In addition reference should also be made to the following manuals when required. TSD 4 700 Workshop Manual TSD 4701 Workshop Manual-Electrical TSD 4736 Product Support Information TSD 4737 Engine Management Systems Before commencing a service schedule always refer to TSD 4736 Product Support Information for any amendments that may have affected the procedures or settings quoted in this chapter since its publication. Precautions The following information should be used as a guide to features that are essential for the safety and health of the operator and the protection of the car. This list is not exhaustive and further details are contained in TSD 4700 Workshop Manual Chapter A. Workshop safety Never work beneath the car if it is only supported on a jack. Always ensure car stands or blocks are used to support the car as a precaution against jack failure. Refer to figure B2-1 for correct support and jacking locations. Raising the front of the car Position the car on a level surface. Fig. B2-1 Car jacking positions and support locations 1 Trolley jack position (front) 2 Car stand positions (front) 3 Sill block positions (front) 5/88 Printed in England © Rolls-Royce Motor Cars Limited 1988 Ensure that the gear range selector is in the park position then remove the gearchange fuse from the fuseboard. (fuse A6 on fuse panel F2). Apply the parking brake and chock the rear wheels. Position a jack under the front pivot mount for the lower triangle levers on the sub-frame (see fig. B2-1) and raise the car to the required height. Alternatively jack up the car using one of the front jacking points situated on the car underbody (see fig. B2-1) utilizing the car jack. Place stands beneath the lower triangle lever/s to support the suspension. Raising the tear of the cat Position the car on a level surface. Ensure that the gear range selector is in the park position. then remove the gearchange fuse from the fuseboard. (fuse A6 on fuse panel F2). If it will be necessary to rotate the transmission during the work procedure the gear range selector should be moved to the neutral position prior to removing the gearchange fuse. Apply the parking brake and securely chock the front wheels. Position a jack beneath the centre of the final drive casing (see fig. 82-1 ), not on the final drive crossmember. Ensure a piece of hard wood is placed between the jack head and the final drive casing. Raise the car to the required height. Alternatively, jack up the car using one of the rear jacking points situated on the car underbody (see fig. B2-1) utilizing the car jack. 4 5 6 Sill block positions (rear) Car stand positions (rear) Trolley jack position (rear) TSO 4702 82-1 Place stands beneath the trailing arms to support the suspension (see fig. B2-1 ). Supporting the car When work is to be carried out which requires the removal or raising off the ground of the road wheels, the suspension and body should always be supported. The use of suitable stands and blocks positioned as necessary in the locations shown in figure B2-1 is recommended. Special wooden blocks should be produced for location beneath the body sill jacking points to prevent the sills being damaged by the support blocks. For dimensional details refer to figure 82-2. If a road wheel is removed, even for a short period, it is always advisable to support the car body at the jacking point adjacent to the wheel being removed as a precaution against jack failure. If the car jacking point on the sill is being utilized to raise the car. position a support beneath the suspension. Gearchange fuse When work is to be carried out on the car which entails running the engine, always ensure that the gear range selector lever is in the park position and that the gearchange fuse {fuse A6 on fuse panel F2) is removed from the fuseboard, prior to starting the engine. Fuel The fuel is highly flammable, and extreme care must be exercised whenever the system is opened (i.e. pipes or unions disconnected) or when the fuel is drained. The following basic rules should apply. Disconnect the battery. A0412 Fig. B2-2 A B C D E F G H Hardwood sill block 44,45 mm (1.750 in) 228,60 mm (9.0 in) 53,98 mm (2.125 in) 25.40 mm (1.0 in) 63,50 mm (2.50 in) 19,05 mm (0.750 in) 101,60 mm (4.0 in) 79,38 mm (3.1 25 in) Place 'No Smoking' signs in the vicinity of the vehicle. Ensure that adequate fire fighting equipment is available in the vicinity of the vehicle. Protective clothing including safety goggles, gloves, and aprons should be worn at all times by the operator. If fuel is to be removed from the fuel tank, it should be siphoned into a suitable covered container. When draining the fuel system on cars fitted with catalytic converters. it is most important that the system is not completely drained by running the engine. otherwise damage to the catalytic converter will result. Fuel pressure The fuel injection system contains fuel that may be under high pressure. 5,2 bar to 5,9 bar (75 lbf/in2 to 85 lbf/ in2 ). Therefore. to reduce the risk of possible injury and fire, always ensure that the system is depressurized (see the relevant section for details). Hydraulic system Before attempting any work on the hydraulic systems of the car. service personnel must be fully conversant with the precautions required to ensure adequate safety and correct system operation. The hydraulic systems operate at high pressure. Pipes and components must never be removed when the hydraulic systems are in a charged state. Before any work. except a specified test. is carried out on the hydraulic systems, they must be depressurized. When fitting new components to the hydraulic systems always ensure that they are suitable for use with a mineral oil hydraulic system. Operation of the brakes (engine not running) The service brakes (i.e. footbrake) consists of two independent all power systems. The power for these systems. in the form of hydraulic pressure, is provided by two engine driven hydraulic pumps. When the engine stops, a limited reserve of pressure remains stored in the hydraulic accumulators which are mounted on the engine. Due to brake operation. natural internal leakage, and levelling system operation, this energy will be slowly depleted. Although a number of brake applications will be available immediately the engine stops, it is recommended that the service brakes are not utilized when the engine is not running. Always remember that if the car is being manoeuvred without the engine running. the footbrake will not stop the car if the pressure in the hydraulic systems is exhausted. Battery charging Batteries give off a gas when charging. which is flammable and explosive. Therefore, never bring a naked flame, lighted cigarette, cigar, or pipe near the battery. Always shield the eyes and face from the battery. 5/88 82-2 Exhaust gases The danger from inhaling exhaust gases cannot be over emphasized. When operating the engine in a confined space or workshop. always ensure that the area is well ventilated. Whenever possible the exhaust gases should be ducted out of the building. Sitting in the car with the car's air conditioning system operating will not eliminate the danger. Health hazards In the interests of health and hygiene, items used in service workshops such as lubricants. anti-freeze. hydraulic system mineral oil, solvents. cleaning agents. adhesives. etc. should be treated with extreme caution. Always follow the manufacturer's instructions for use. storage, and waste disposal. These items can be of a toxic nature and must not be swallowed or the vapours that may be given off inhaled. Always keep these items away from children. Engine oils Prolonged and repeated contact with mineral oil will result in the removal of natural fats from the skin, leading to dryness. irritation, and dermatitis. In addition. used engine oil contains potentially harmful contaminants which may cause skin cancer. Adequate means of skin protection and washing facilities should be provided. Health protection precautions Avoid prolonged and repeated contact with oils. particularly used engine oils. Wear protective clothing. including impervious gloves where practicable. Do not put oily rags in pockets. Avoid contaminating clothes, particularly underpants. with oil. Overalls must be cleaned regularly. Discard unwashable clothing and oil impregnated footwear. First Aid treatment should be obtained immediately for open cuts and wounds. Use barrier creams, applying before each work period, to help the removal of oil from the skin. Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Preparations containing lanolin replace the natural skin oils which have been removed. Do not use petrol. kerosine, diesel fuel, gas oil, thinners, or solvents for washing skin. If skin disorders develop, obtain medical advice. Where practicable. degrease components prior to handling. Where there is a risk of eye contact, eye protection should be worn. for example. chemical goggles or face shields; in addition an eye wash facility should be provided. See also HSE Cautionary Notice SHW 397 'Effects of Mineral Oil on the Skin'. Cleaning agents and solvents When using cleaning agents and solvents the following precautions should be observed. 5/88 Printed in England © Rolls-Royce Motor Cars Limited 1988 Cleaning agents and solvents should only be used in well ventilated areas. Ensure that they are kept in clean containers and that the lids fit securely. Always replace the lids immediately after use. Do not store or carry solvents in open containers. Clearly label all containers. The issue of all solvents should be closely controlled. Containers should be kept in locked storerooms with a responsible person in possession of the key. In the event of a major spillage. the area should be evacuated and then thoroughly ventilated. Do not dispose of solvents into open drains. Avoid skin contact as much as possible. If contact is likely, wear PVC gloves and an appropriate barrier cream. Always protect eyes with goggles if there is any danger of the solvents coming into contact with the eyes. Use solvents sparingly, cleaning only small areas at a time. After use cloths used for cleaning should be deposited in a closed metal container. Care should be taken when working in a pit to avoid being overcome with the vapours from some solvents. These are heavier than air, and therefore collect at low levels. Do not smoke in the vicinity of solvents. Do not allow solvents near any naked flame. hot surfaces. or welding arcs. Fuel (Petrol) Fuel is a narcotic and inhalation of heavy concentrations of vapour should be avoided. Repeated or prolonged contact with the skin can cause skin disorders. It should not be used for cleaning the skin as it removes the natural oils. Fuel may contain up to 5% of Benzene as an antiknock additive. Benzene is extremely injurious to health (being carcinogenic) therefore, all contact should be kept to an absolute minimum, particularly inhalation. Suitable protection should always be used e.g. gloves, aprons, goggles. Fuel has a sufficiently high vapour pressure to cause a hazardous build~up of vapour in poorly ventilated areas. The vapours are irritant to the eyes and lungs and if high concentrations are inhaled it may cause nausea, headache. and depression. Handling asbestos These notes are for the guidance of service personnel handling components containing asbestos. There is no application on current Rolls-Royce or Bentley cars involving the use of free asbestos fibres. All components containing asbestos are produced with the asbestos bonded into a matrix. Asbestos is used in the following components. Heat shields. Parking brake pads. Engine gaskets. Gearbox brake bands. TSO 4702 B2-3 In non current cars asbestos is also used in service brake pads and linings and where applicable in the brake servo linings. The form of asbestos used in these applications is chrysotile asbestos. When disposing of parts identified as containing asbestos. refer to Waste products disposal on this page. It is not recommended to cut, abrade, or machine parts containing asbestos. In the event of it being necessary, dust formation is reduced by wetting of the work piece; use hand tools or low speed tools where possible. Use of local extraction and approved masks is recommended. The extracted material may need to be treated as asbestos dust. Waste products disposal Environmental protection precautions It is illegal to pour used oil on to the ground. down sewers or drains, or into water courses. The burning of used engine oil in small space heaters or boilers is not recommended unless emission control equipment is fitted; in cases of doubt check with the Local Authority. Dispose of used oil through authorised waste disposal contractors. to licensed waste disposal sites, or to the waste oil reclamation trade. If in doubt. contact the Local Authority for advice on disposal facilities. Always avoid skin contact with waste products whenever possible (see Health hazards on page B2-3). Asbestos When disposing of parts identified as containing asbestos, the following procedures are advised. Hard waste, i.e. parts where the asbestos is bonded by a matrix, may be handled and disposed of without special precautions [ref. United Kingdom Control of Pollution (Special Waste) Act 1980]. [lust containing asbestos should be removed by vacuum cleaning. In the United Kingdom the vacuum cleaner must be approved to BSI 5415 Amendment 4, Section 2.2 1976 - Vacuum Cleaner·Wet and/or Dry. The bags containing the dust should be disposed of by a method approved by your Local Authority. When cleaning or servicing vacuum cleaners it is necessary to wear an air fed, or approved disposable mask. Use of a wet cloth for cleaning is advised, which should be disposed of in a similar manner to the asbestos dust. Further information regarding the handling of asbestos can be obtained in the United Kingdom from local Health and Safety offices. Shock dampers Each shock damper contains nitrogen gas under pressure. On no account should the damper be subjected to undue force of any description. Do not clamp the damper in a vice. To render a shock damper safe for disposal, drill a small hole 25 mm ( 1.0 in) from the closed end of the outer tube. The escaping gas should not be allowed to come into contact with the eyes or skin whilst under pressure. Immediately the hole has been drilled, stand clear and allow the nitrogen gas to disperse to atmosphere. Car protection Prior to commencing a service schedule the car should be suitably protected. For this purpose. car protection kit RH 2662. wing covers RH 2684, and wing cover liners RH 2685 should be used. Hydraulic braking and levelling system WARNING Use only hydraulic system mineral oil {LHM) to replenish the braking and levelling systems. Do not use brake fluids (Castrol RR363. Universal. or any other type). The use of any type of brake fluid, even in very small amounts. will cause component failure necessitating extensive rectification to the braking and levelling systems of the car. Always ensure before fitting any seals. hoses, pipes. etc. that they are suitable for a mineral oil system. For details of correct component identification reference should be made to TSD 4 700 Workshop Manual Chapter G. Always ensure that two sealed containers of hydraulic system mineral oil (LHM) are fitted in the luggage compartment. Always ensure that no foreign matter enters the systems when work is being carried out. Hydraulic system mineral oil (LHM) Hydraulic system mineral oil is Green in colour. It is essential that only approved hydraulic system mineral oil is used (see Chapter A). Contamination of mineral oil hydraulic systems or components with any conventional vegetable or synthetic type of brake fluid will cause seals and hoses to deteriorate which could result in eventual brake faults. To avoid contamination all mineral oil containers and components should be stored in a clearly defined area away from that used for conventional brake fluid. Hydraulic system mineral oil can cause damage to tyres. In the event of mineral oil coming into contact with a tyre. damage can be prevented if the mineral oil is removed immediately using a soap solution. Finally, wash the tyre with clean water. Battery It is imperative that the battery is disconnected before commencing work on the electrical system or components. or if any electric arc welding is to be used on the car. Always remove the battery from the car before charging. 5/88 B2-4 Lambswool rugs To clean the rugs remove them from the car, then shake and beat them to release any dust and grit. Comb the wool with a suitable wire comb or coarse bristle brush to free the wool fibres. If a rug is wet. allow it to dry at room temperature. Never expose the rug to direct heat or dry it on a radiator or towel rail. To remove slight stains or congealed dirt use a mild carpet shampoo solution. Immerse a clean cloth into the solution. then lightly wring out. Clean an area of approximately 0, 1 m 2 (1 ft2). taking care not to over-wet the rug. then wipe with a clean dry cloth. Repeat this procedure over the remaining area of the rug. Allow the rug to dry then comb the rug to free the wool fibres. If the rugs become heavily soiled or stained they should be sent to a specialist sheepskin cleaner. Never send the rugs to a laundry or drycleaner. Never use an aqueous washing process. Always ensure that the cleaning specialist is aware that the inner felt of the rugs must be removed prior to the cleaning process being carried out. Engine cooling system Every three months; check the coolant level. If necessary top-up with the correct anti-freeze/water mixture. Regular maintenance In addition to the service schedules listed, the following maintenance should be carried out. Engine Weekly or every 800 kilometres (500 miles) whichever is the earlier; check the engine oil by means of the dipstick; top-up if necessary. Lamp units Weekly; check the lamp units for operation; rectify any faults. Tyre pressures Weekly; check the tyre pressures including the spare; adjust if necessary. Check the tread depth of all tyres and inspect the tyres for damage. Windscreen and headlamp washer reservoirs Weekly; check the washer fluid level; top-up if necessary. Hydraulic reservoirs Monthly; check the level of hydraulic mineral oil in the reservoirs. Depressurize the hydraulic systems by pumping the brake pedal until the low brake pressure warning panels on the facia illuminate. Continue-to pump the pedal for at least a further 20 applications to ensure complete depressurization. Start and run the engine for four minutes with the car unladen. prior to checking the level. Top-up if necessary to the indicated maximum level. Use only hydraulic system mineral oil (LHM). Refer to page B2-4 for further information before carrying out this operation. 5/88 Printed in England © Rolls-Royce Motor Cars Limited 1988 TSO 4702 B2-5 Section B3 Engine Change the engine oil The sump should be drained when the engine is warm, preferably after the car has completed a run. To drain the oil, position the car over a pit or on a ramp. Place a container in position beneath the drain plug situated on the right-hand side of the sump. Remove the drain plug and allow the oil to drain from the sump. Do not flush the sump with paraffin or petrol. Fit the drain plug ensuring that the washer is correctly positioned and in good condition. To replenish the sump with oi I, open the filler cap marked ENGINE OIL (see fig. B3-1 ). Add clean oil to the engine and after allowing sufficient time for the oil to reach the sump, check that the oil is up to the MAX mark on the dipstick. Do not overfill. In order to obtain an accurate indication of the oil level ensure that the car is standing on level ground. Important The engine lubrication system incorporates a therrnostatical ly controlled oi I cooler, therefore the following additional procedure must be carried out to ensure the correct oil level is obtained. Drive the car to enable the engine oil to attain the temperature required to actuate the oil cooler thermostat. To ascertain that the thermostat has actuated, a rise in the temperature of the oil cooler return pipe situated adjacent to the air intake filter can be felt. This temperature rise occurs as hot oil begins to flow from the oil filter housing, where the thermostat is situated, to the oil cooler mounted in front of the coolant radiator matrix. Do not attempt to attain the required engine oil temperature rise with the car stationary. When it has been ascertained that the engine oil has been passing through the cooler, thus filling this part of the lubrication system, switch off the ignition. Allow sufficient time to elapse for the oil to drain into the sump, then check the oil level in the normal manner as described previously. Do not check the oil level with the engine running. Fig. B3-1 Engine oil filter and dipstick Fig. 83-2 Engine oilfilter location pedestal until the rubber seal contacts the sealing face, then tighten the filter a further half turn; do not over-tighten. Renew the engine oil filter Drain the engine oil as described under Change the engine oil. Place a container under the filter to collect any oil that may be spilt. Remove the filter by unscrewing it from the engine in an anti-clockwise direction (see fig. 83-2). Thoroughly clean the filter seating face on the engine. Lightly smear the rubber sealing ring on the new filter with clean engine oil. Screw the filter onto the 9/88 Check the drive belts Before commencing to adjust the drive belts inspect them for signs of wear or cracking. Any belts found unsatisfactory should be renewed. TSO 4702 Printed in England © Rolls-Royce Motor Fill the engine with clean engine oil until the MAX level is reached on the dipstick. Run the engine and check the filter joint for leakage. Carry out the full oil level check procedure as described under Change the engine oil. Cars Limited 1988 83-1 If after adjustment, a matched pair of belts have a marked variation in tension, a new pair should be fitted. Always renew both belts in a matched pair, even if only one belt is faulty. Two belt tension loads are specified; a new belt load for replacement (new) belts and a retensioning load for belts which are satisfactory for further service. The belt tension must be checked at a point midway between two pulleys (see fig. 83-3) by use of a belt tension meter. Important Always ensure that the drive belts are tensioned to the figures given below. The incorrect tensioning of a belt can be the cause of belt faults such as breakage. slip, twist, etc. A belt tension meter such as the Atlas Capco or an equivalent type should be used in order to obtain the accuracy required. Belt dressing must not be applied to prevent belt slip. Crankshaft to coolant pump/steering pump The belt tension meter reading should be as follows, New belt load 40,8 kgfto45.4 kgf (90 lbf to 100 lbf) Retensioning load 36,3 kgfto 40,8 kgf (80 lbfto 90 lbfl The tension of this matched pair of belts is adjusted by altering the position of the steering pump. Slacken the setscrew securing the steering pump mounting bracket pivot and the clamping setscrew on the belt tensioner situated below the steering pump (see fig. 83-3). Carefully adjust the tensioner until the correct belt tension is attained.

Plug gap setting 1,0 mm (0.040 in). Before removing the sparking plugs the 9/88 Printed in England © Rolls·Royce Motor Cars Limited 1988 Fig. 83-5 Distributor lubrication point surrounding area should be thoroughly cleaned to preventthe ingress of foreign matter when the plugs are removed. Fit the new plugs ensuring that the gaps are correctly set and that each plug is fitted with a sealing washer. Torque tighten each plug to between 24,4 Nm and 29,8 Nm (2,5 kgf m and 3,0 kgf m, 18 lbf ft and 22 lbf ft). Lubricate the distributor (Not applicable to Bentley Turbo R) Lubrication of the spindle is the only routine maintenance required. To carry out this operation remove the moulded cap of the distributor and the rotor arm. Do not remove the cover from the distributor baseplate (see fig. B3-5). Lubricate the spindle shaft bearings by applying two drops of engine oil to the spindle beneath the rotor arm. Clean the cap internally and externally prior to fitting using a suitable clean cloth. TSD 4702 83-3 Clean the distributor caps (Bentley Turbo R) To remove the distributor caps, press down on the heads of the retaining hooks and turn them to their released position. Carefully lift off each cap noting its position. Clean the caps internally and externally using a suitable clean cloth. When fitting the caps always ensure they are correctly positioned and secured by the retaining hooks. Check all induction system hoses (Bentley Turbo RI Inspect the induction system hoses for serviceability. Renew all faulty hoses. Check the hose clips for tightness but do not overtighten. When renewing a hose, thoroughly clean the area around the hose connections prior to removal. This procedure will prevent the ingress of foreign matter into the induction system. If the connections are to remain disconnected for a period of time, the open pipe ends should be suitably blanked. Lubricate the accelerator linkage Lubricate the accelerator linkage ball joints and clevis pins with approved grease. Examine the ball joints for wear and adjust if necessary. Renew any worn clevis pins. Examine the linkage for correct operation. For details of linkage setting procedures, reference should be made to TSD 4737 Engine Management Systems Manual, Chapter K.

Place a clean container beneath the radiator drain plug. Remove the radiator drain plug. Remove the expansion bottle pressure cap and allow sufficient coolant to drain from the system for the coolant level to fal I below that of the thermostat housing. Fit the radiator drain plug. Disconnect the electrical connector from the thermostat housing cover. Remove the setscrews securing the thermostat housing cover. Remove the cover. The cover can be moved away from the housing without detaching the outlet hose. Lift the thermostat from the housing (see fig. B4-1). Remove the old gasket material from the thermostat housing and cover. Ensure that no material enters the thermostat housing. Check that the two faces are clean and dry. Insert a new thermostat into the housing. Place a new gasket in position on the housing and fitthe cover. Connect the electrical connection removed from the housing cover. Top-up the cooling system with the correct coolant mixture as described under Renew the coolant. Reverse flush the coolant system Warning Do not under any circumstances use an alkaline compound or detergent to clean the system. Such compounds have a detrimental chemical action on aluminium alloys. Drain the engine coolant system as described in Renew the coolant. Disconnect the expansion bottle hoses and fit blanks to the radiator stub pipes. Remove the top and bottom hoses from the radiator matrix. Fit a waste pipe to the upper {inlet) connection of the radiator. Apply mains water under pressure through the lower (outlet) connection of the radiator until the water runs clear. This should remove all loose sediment. Remove the thermostat as described in Renew the thermostat, then replace the cover. Produce a suitable adaptor to fit onto the cover outlet and connect via a hose to the mains water supply. Apply mains water pressure. Flush the coolant passages until the water runs clear. Fitthe thermostat, and cover. Use a new thermostat cover gasket. To flush the heater system, detach the matrix feed 9/88 Printed in England © Rolls-Royce Motor Cars Limited 1988 Fig. 84-1 Thermostat housing assembly hose at the water tap and the return hose at the coolant pump connection. Connect a waste pipe to the feed hose connection and a water main connection to the return connection. Turn on the water and reverse flush the matrix until the water runs clear of foreign matter. Examine the coolant hoses for deterioration or damage and renew as necessary. Connect all hoses and fill the system with the recommended coolant mixture as described under Renew the coolant. Examine the condition of all coolant hoses Inspect all coolant hoses for sign of deterioration, cracking, weak spots, etc. Any faulty hose should be removed and a new hose fitted. When renewing a hose always ensure that it does not foul other components and that it is not kinked so as to cause complete or partial restriction of the coolant flow. Check all coolant hose clips for tightness Examine all the coolant hose connections for signs of leakage and check the worm drive clips for tightness. Never overtighten a clip in an attempt to seal a leaking connection. In the event of a hose connection leaking when the worm drive clips have been tightened, drain the cooling system to a level below the leaking hose. Remove and inspect the hose and its connecting component for signs of damage. If necessary renew the faulty component and refill the system with coolant as described in Renew the coolant. TSO 4702 B4-1 Renew the coolant Drive the car onto a ramp; move the gear range selector to the park position and apply the parking brake. Remove the gearchange fuse from the fuse board, (fuse A6 on fuse panel F2). Place a container beneath the radiator drain plug to collect the coolant. Remove the radiator drain plug. Remove the expansion bottle pressure cap and allow the coolantto drain into the container. Check all hoses for serviceability and renew as necessary. Fill the system with fresh coolant of the specified concentration as follows. Warning This procedure must be carried out exactly as described. Incorrect filling will create air locks within the engine and cause irreparable damage due to resultant overheating. Ensure that the radiator drain plug is fitted and tightened. Remove the bleed plug from the top of the radiator, by unscrewing it anti-clockwise. Disconnect the radiator to expansion bottle hose from the radiator, and hold the hose above the level of the radiator top tank. Fill the expansion bottle to the MAX level mark. Fit the pressure cap to the expansion bottle. Using a small funnel or a suitable size hose, inserted in the bleed plug aperture, fill the system using the correct coolant/anti-freeze and water mixture. Pour the mixture into the system slowly to avoid air locks. When the coolant flows from the radiator stub pipe, reconnect the hose. Fit the radiator bleed plug. Start and run the engine. Turn the air conditioning system function control to the defrost position. This procedure opens the heater system water tap. Run the engine for a minimum of five minutes. After five minutes, check that warm air is passing from the demister outlets. Run the engine for a further two minutes at between 2000 rev/min and 2500 rev/min to purge the system of air. Switch off the ignition. If necessary, carefully remove the expansion bottle pressure cap and top-up the coolant to the MAX level. Note Removal of the pressure cap while the engine and radiator are still hot requires extreme care. If the cap is removed too soon after stopping the engine, scalding fluid and steam, under pressure, can be blown out. To remove the cap, turn it slowly anticlockwise until a check position is reached. Wait for any pressure in the system to be exhausted, then continue to turn the cap until it is released. Check the coolant anti-freeze concentration The cooling system is filled initially with a coolant solution comprising equal parts of approved coolant/anti-freeze and water. This mixture gives frost protection down to a temperature of -37°C (-35°F}. The coolant should contain fifty percent of an approved coolant/anti-freeze at all times, as this not only provides frost protection, but also prevents corrosion of the coolant passages, and raises the boiling temperature of the coolant. The trade name of the coolant/anti-freeze is ICI 007/400F (obtainable under a Rolls-Royce and Bentley label} and should be used all year round. Do not mix ICI 007/400F ortop-up with any other brand of coolant/anti-freeze. The anti-freeze concentration should be checked in the expansion bottle. If the strength of the coolant mixture requires increasing, sufficient coolant should be drained from the radiator and replaced with undiluted coolant/antifreeze (see fig. 84-2). Afterwards run the engine until normal operating temperature is attained and the new coolant/antifreeze has become thoroughly mixed with the existing mixture. Stop the engine and again check the concentration in the expansion bottle. Failure to allow the new anti-freeze to circulate properly will result in a false reading. An acceptable level of anti-freeze concentration is between 45% and 50%. Therefore, as a hydrometer may be inaccurate where readings above 40% are expected, it is recommended that a refractometer is used. For details refer to TSD 4700 Workshop Manual, Chapterl. Note If a refractometer is not available and a hydrometer has to be used a scale reading of between 1,06 and 1,07 should be obtained, with the coolant at room temperature, for the mixture to be correct. Check the coolant level Warning The cooling system becomes pressurized during engine running. Therefore, extreme care should betaken when removing the expansion bottle pressure cap from an engine that is warm or at normal running temperature. Do not remove the bleed plug from the radiator or disconnect the radiator to expansion bottle hose when the system is pressurized. Routine check To check the level outside a normal service schedule (e.g. Regular maintenance) and when no cooling/ heating system fault is reported or suspected. proceed as follows. If the engine is hot ensure that the coolant level in the translucent expansion bottle is at the MAX mark. Top-up if necessary and repIace the expansion bottle cap. If the engine is cold ensure that the coolant level in the translucent expansion bottle is half-way between the MIN and MAX marks. Top-up if necessary and replace the expansion bottle cap. 9/88 84-2 If the coolant level in the expansion bottle is either below the MIN mark or there is no coolant in the expansion bottle, carry out the following Full check procedure. Furl check Ensure the gear range selector is in the park position and apply the parking brake. Remove the gearchange fuse from the fuseboard (fuse A6 on fuse panel F2). Check the coolant level in the translucent expansion bottle. If the level is low or the bottle is empty, allow the engine to cool, then remove the pressure cap from the expansion bottle. To remove the cap, turn it slowly anti-clockwise until a check position is reached. Wait for any pressure in the system to be exhausted, then continue to turn the cap until it is released. Remove the bleed plug from the top of the radiator, by unscrewing it anti-clockwise. Disconnect the radiator to expansion bottle hose from the radiator, and hold the hose above the level of the radiator top tank. Fill the expansion bottle to the MAX level mark. Fit the pressure cap to the expansion bottle. Using a small funnel or a suitable size hose, inserted in the bleed plug aperture, fill the system using the correct coolanuanti-freeze and water mixture. Pour the mixture into the system slowly to avoid air locks. When coolant flows from the radiator stub pipe, reconnectthe hose. Fit the radiator bleed plug. Start and run the engine. Turn the air conditioning system function control to the defrost position. This procedure opens the heater system water tap. Run the engine for a minimum of five minutes. After five minutes, check that warm air is passing from the demister outlets. Run the engine for a further two minutes at between 2000 rev/min and 2500 rev/min to purge the system of air. Switch off the ignition. If necessary, carefully remove the expansion bottle pressure cap and top-up the coolant to the MAX level. Note Removal of the pressure cap while the engine and radiator are still hot requires extreme care. If the cap is removed too soon after stopping the engine, scalding fluid and steam, under pressure, can be blown out. To remove the cap, turn it slowly anti· clockwise until a check position is reached. Wait for any pressure in the system to be exhausted, then continue to turn the cap until it is released.

The smallest particle of dirt in the transmission fluid could interfere with the correct operation of the unit. It is also important that only an approved fluid is used (see Chapter A}. Check the transmission fluid level The fluid level can only be checked accurately when the car is standing on a level surface, the engine is running at idle speed, and the transmission fluid is at normal operating temperature approximately 77°C ( 170°F). The dipstick and filler tu be are situated on the right-hand side of the engine compartment. On four door cars remove the protective cover from the windscreen wiper mechanism to gain access to the dipstick. Ensure that the following safety procedure is undertaken to isolate the mechanism prior to removing the cover. Ensure that the windscreen wiper control switch situated on the facia is in the off position. Remove a windscreen wiper relay, preferably number three. On cars prior to 1989 model year the relay is situated adjacent to the windscreen washer reservoir (see fig. B5-1 A}. On 1 989 model year cars the relay is situated between the spring pot brackets on the right-hand side of the engine compartment. To gain access to the relay. Remove the cover panel (see fig. B5-1 C). To remove the relay pull it vertically from its rnounti ng. Always clean the top of the dipstick before removing it from the filler tube. As an initial check. the fluid level may be checked after starting from cold as follows. Apply the parking brake. Start and run the engine for three to four minutes with the gear range selector in the park position. Allow the engine to achieve a normal idle speed. Whilst sitting in the driving seat, firmly apply the footbrake and move the gear range selector through the full range of gear positions pausing briefly in each range. Return the selector to the park position. Immediately check the fluid level with the engine running at idle speed. The level should be 25 mm (1 in) below the FULL HOT mark on the dipstick. Top-up to this level if necessary. Important When checking the fluid level with the engine running, take care to avoid any moving parts such as drive belts, pulleys, fan blades, etc. Care should also be taken to avoid contact with hot engine components. After this initial check a further check should be carried out as fol lows.

This should ensure the transmission has reached normal operating temperature. It is essential thatthis temperature is attained. Do not top-up the fluid level to the FU LL HOT mark on the dipstick when the fluid is only warm, as this will result in an overflow situation when the normal operating temperature is attained. Overfilling will result in fluid being discharged from the transmission breather pipe. Position the car on a level surface, firmly apply the parking brake and select park with the gear selector lever. Carry out the procedure described for the in itia I check. With the transmission fluid at normal operating temperature the level of the fluid should be within the cross hatched area marked on the dipstick (see fig. 85-1). TSD 4702 85-1 If necessary add fluid by pouring it down the tiller tu be, with the engine still running, until the flu id is to the FU LL HOT mark on the dipstick. Do not overfill. When the fluid level is correct. switch off the engine and fit the windscreen wiper mechanism cover and relay. Renew the transmission fluid Place a clean container having am inimum capacity of 3 litres (5 Imp pt, 6 US pt) beneath the drain plug situated on the corner of the transmission sump (see fig.B5·2). Remove the drain plug and allow the oi I to drain from the sump. After draining the sump, ensure that the sump plug is clean then fit it to the sump. Torque tighten the plug to between 21 Nm and 27 Nm (2, 1 kgf m and 2,7 kgfm, 151bfftand201bfft). From within the engine compartment, remove the transmission dipstick as described under Check the transmission fluid level. Add 2,8 litres (5 Imp pt, 6 US pt) of an approved fluid to the sump, pouring the fluid down the filler tube. Check the fluid level as described under Check the transmission fluid level. Fit a new intake strainer Drain the transmission sump as described under the heading. Renew the transmission fluid, then proceed as follows. Remove the setscrews securing the transmission sump and lower the sump. Drain the fluid from the sump and discard the gasket. Unscrew the setscrew securing the intake strainer and pipe assembly to the transmission; remove the strainer assembly (see fig. 85-3). Remove the intake pipe from the strainer and discard the strainer. Clean the transmission sump and the intake pipe with paraffin and dry with compressed air. Fit a new 'O' ring to the intake pipe and lubricate the 'O' ring with clean transmission fluid. Ensure that a new rubber seal is fitted to the pipe bore in the new intake strainer, then fit the intake pipe into the strainer. Fit the intake strainer and pipe assembly to the transmission and torque tighten the securing setscrew to 14 Nm (1 .4 kgf m, 10 lbfft). Fit the transmission sump using a new gasket and torque tighten the sump setscrews to 16 Nm (1,7kgfm, 121bfft). Add 4,5 litres (8 Imp pt, 9.6 US pt) of an approved fluid to the sump, pouring the fluid down the filler tube, then follow the fluid level checking procedure described under Check the transmission fluid level. Lubricate the gear range selector control rod Lubricate the clevis pins in the control rod linkage at the left-hand side of the transmission, with a few drops of clean engine oil.

Remove the level plug located in the rear face of the final drive casing. The oil in the casing shou Id be up to the level plug orifice. If necessary, top-up with an approved oil. Fit the level plug complete with a new joint washer. Renew the final drive oil It is advisable to carry out this operation when the oil is warm, e.g. immediately after the car has completed a run. Position the car on a ramp or over a pit and clean the area around the drain and level plugs (see fig. B7-1). Place a container beneath the drain plug, then remove both the drain and level plugs. When the oil has drained, fit the drain plug complete with a new joint washer. Using a syringe, fil I the casing to the level plug orifice with an approved oil. Approximately 2,3 litres (4.0 I mp pt, 4.8 US pt) of oil will be required. Fit the level plug complete with a new joint washer and check for leaks. Check the condition of the drive-shaft joint covers The drive-shaft joints enclosed by convoluted seals, are filled with lubricant on initial assembly. If upon inspection a seal is found to be leaking or damaged the joint should be inspected and a new seal fitted as described in TSD 4700 Workshop Manual, Chapter J.

B8-1 ). If necessary, top-up to th is level with approved flu id. Start and run the engine until it reaches normal operating temperature, approximately 77°C (170°F), then stop the engine. Remove the filler cap and check the fluid level in the reservoir. If necessary, add an approved fluid to raise the level to the MAX mark on the dipstick; do not overfill. Ensure that the filler cap is securely replaced. Check the condition of the steering ball joints and covers Examine the condition of the rubber cover seals on the track rod ball joints (see fig. B8-2) and check the ball joints for wear and damage. Fig. 88-1 If the bal I joints are worn or the rubber covers are damaged or in poor condition, new ball joints should befitted. For full information refer to TSD 4700 Workshop Manual, Chapter N. Check the condition of the steering rack convoluted seals Examine the condition of the convoluted seals on the rack and pinion unit (see fig. B8-2) and check the tightness of the seal clips. If the seals are satisfactory, tighten the clips as necessary. If the convoluted seals are found to be damaged or in poor condition, the rack and pinion unit shou Id be removed from the car and new seals fitted.

Check the ball joints for wear and examine the rubber covers for serviceability. If the ball joints are worn or the rubber covers are damaged or in poor condition, new bal I joint assemblies should be fitted as necessary. For ful I information refer to TSD 4700 Workshop Manual, Chapter H. Check the condition of the rear strut convoluted seals Examine the condition of the convoluted seals on the rear suspension struts. If the seals are found to be damaged or in poor condition, the struts should be removed as described in TSD 4700 Workshop Manual, Chapter G and new seals fitted. Lubricate the levelling valve ball joints Examine the rubber covers on the levelling valve ball joint and torsion rod pivot for serviceability (see fig. 89-3). If the covers are satisfactory, ease them back and clean the joints. Lubricate the joints with an approved grease. When cover renewal is necessary proceed as follows. Mark the torsion bar clamp and the stabilizer bar with correlation marks to assist in repositioning of the torsion bar clamps upon assembly. Slacken the torsion bar 'U' bolt attached around the stabilizer bar (see fig. 89-3). Withdraw the torsion bar from the levelling va Ive ball joint and spherical bearing. Discard the covers and clean the joints. Lubricate the joints with approved grease. Fit new rubber covers and assemble the components by reversing the removal procedure. Align the correlation marks then push the torsion bar as far as possible into the spherical bearing. Withdraw the torsion bar between 0,50 mm and 0, 75 mm (0.020 in and 0.030 in), then torque tighten the torsion bar 'U' clamp nuts to between 5,2 Nm and 6,2 Nm (0,53 kgf m and 0,63 kgf m; 3.8 lbf ft and 4.6 lbf ft). Ensure that the area of contact between the clamp and the stabilizer bar is free of grease, oil, etc. Check the car levelled height as described in TSO 4700 Workshop Manual, Chapter G.

Set the steering in the straight ahead position. Set suitable alignment equipment onto the front wheels following the manufacturer's instructions and take a reading. If adjustment is necessary, slacken the pinch bolts securing the track rod adjusters (see fig. B9-4). Rotate the adjusters to bring the wheels into the straight ahead position {zero toe-in}. Rotate the adjusters by equal amounts to give an overall toe-in figure of between 0° 7' and 0° 17'. Tighten the pinch bolts then check the toe-in again. When the toe-in is correct torque tighten the pinch bolts and fit new split pins. 9/88 89-2 Section B10 Brake and hydraulic systems A wARNING Use only hydraulic system mineral oil (LHM) to replenish the braking and levelling systems. Do not use brake fluids (Castrol RR363, Universal, or any other type). The use of any type of brake fluid, even in very smal I amounts, will cause component failure necessitating extensive rectification to the braking and levelling systems of the car. Always ensure before fitting any seals, hoses, pipes, etc., that they are suitable for a mineral oil system. For details of correct component identification reference should be made to TSD 4700 Workshop Manual, Chapter G. Always ensure thattwo sealed containers of hydraulic system mineral oil (LHM} are fitted in the luggage compartment. Always ensure that no foreign matter enters the systems when work is being carried out. Check the integrity of the reservoir seal In order to protect against claims of liability for hydraulic system contamination, it is recommended that the integrity of the reservoir locking wire and seal are checked (see fig. B10·1 I prior to work being undertaken. If possible this operation should be carried out in the presence of the owner or his/her representative. If the seal or wire are broken, or ifit is suspected, that the hydraulic system is contaminated, carry out the test procedure detailed in TSD 4700 Workshop Manual, Chapter G. It is important that the test is carried out even when the hydraulic system mineral oil is to be renewed as this will not prevent the deterioration of components which have been in contact with contaminated mineral oil. Brake fluids and mineral oil are immiscible and with large amounts of contamination separation of the fluids will occur on standing, due to the greater density of the conventional fluids. A further indication of the mixing of conventional brake fluid and mineral oil is its cloudy appearance. To carry out contamination tests, a kit is available from Rolls-Royce Motor Cars Limited part number RH 2841. Important Always wire lock and seal the reservoir lid locking rings after it has been ascertained that the systems are not contaminated and all work on the systems has been completed. 9/88 Printed in England © Rolls-Royce Motor Cars Limited 1988 Fig. 810·1 Hydraulic system reservoirs 1 Hydraulic systems seal 2 Reservoir filler connection and level indicator (No. 2 system) 3 Reservoir filler connection and level indicator (No. 1 system) Check the reservoir mineral oil levels The mineral oil reservoirs of the hydraulic systems are situated on the left-hand side of the engine compartment. To check the oil level, first depressurize the hydraulic systems by pumping the brake pedal until the two warning panels situated on the facia illuminate. With the car unladen and on level ground, start and run the engine for approximately four minutes to charge the systems. The mineral oil level in both reservoirs should be checked by observing the position of the green indicator tube in the sight glass situated on the top of each reservoir (see fig. 810-1 ). The level is correct when the indicator tube is level with the top of the black band on the sight glass. If the indicator tube is below the black band, the reservoir requires topping-up with an approved hydraulic system mineral oil. It is important that only an approved hyd rautic system mineral oil is used (see Chapter A) and that exceptional cleanliness is observed when topping-up the hydraulic systems. Under no circumstances should a conventional (i.e.RR363 or Universal type) brake fluid be used. Note Ensure that brake disc pad renewal is not required prior to topping-up the reservoirs. When new pads are fitted mineral oil will be returned to the reservoirs (see Check the brake disc pads for wear}. TSD 4702 810-1 To top-up a reservoir proceed as follows. Clean the area around the reservoir filler connection and remove the blanking plug from the aperture. Obtain a dispenser of hydraulic system mineral oil. Pull the plug from the top of the dispenser cap, then enter and firmly push the targer end of the filler tube supplied with the dispenser into the cap. The tube will lock into the cap and also pierce the dispenser seal situated below the cap when fully inserted. Taking care notto squeeze the dispenser, enter the special nozzle on the filler tube into the hole in the reservoir filler. Push the nozzle in fully, then turn the nozzle clockwise to lock it into position, When inserting the nozzle sufficient pressure will have to be applied to overcome the spring pressure of the ball valve which seals the reservoir filler. With the nozzle correctly inserted, squeeze the dispenser to inject the mineral oil into the reservoir until the correct level is attained. To release the nozzle turn it anti-clockwise. Remove any mineral oil that may have been spilt, then insert the blanking plug into the filler aperture. Repeat the procedure on the other reservoir if necessary. Check the condition of all brake pipes and hoses Examine the metal brake and levelling system pipes for damage and corrosion, particularly those in exposed positions. Examine the hoses for chafing and surface cracking. Faulty pipes and hoses should be renewed as described in TSD 4700 Workshop Manual, Chapter G. Renew all flexible hoses Depressurize the hydraulic systems as described in TSD 4700 Workshop Manual, Chapter G. Completely drain the mineral oil from the hydraulic systems as described under Renew the hydraulic system mineral oil. Thoroughly clean the area around the hose connections and remove the respective hoses noting the following points. To avoid contamination fit the new hose immediately the old hose has been removed. Alternatively, fit approved blanks to the open connections until the new hoses are to be fitted. Before fitting a new hose, ensure it is thoroughly clean and conforms with the hydraulic system mineral oil requirements. When fitting new hoses, ensure that they are routed to clear other components and that clearance is maintained during full suspension or engine movement where applicable. Tighten all pipe connections to the torque figures given in TSD 4700 Workshop Manual, Chapter G. Overtightening can cause pipe flare distortion and consequent leakage. When all the hoses have been renewed, ensure that all the bleed point nipples are closed, then fill the systems with new hydraulic system mineral oil as described under Renew the hydraulic system mineral oil. Bleed the hydraulic systems as described in TSD 4700 Workshop Manual, Chapter G and check the systems for leaks. Renew the brake caliper seals To renew the brake caliper seals it is necessary to remove the brake calipers from the car. For full details, refer to TSD 4700 Workshop Manual, Chapter G. Check the brake disc pads for wear Remove the road wheel trims and slacken the wheel nuts. Jack-up the car and support it with stands and sill blocks (see Section 82). Remove the road wheels and examine all the brake disc pads for wear. All the brake pads must be renewed when any of the pad linings are worn to within 3 mm (0.12 in) of the steel backing plate. The pads should also be renewed if this thickness is likely to be reached before the next service check. To renew the brake pads, refer to TSD 4700 Workshop Manual, Chapter G. If new brake pads are to be fitted which have different recommended linings from those on the old pads, the disc faces should be cleaned prior to fitting the new pads. All traces of the old pad lining material should be removed by hand rotating the disc whilst applying coarse grade emery cloth to the disc faces. Do not emery the disc faces radially. Always ensure that the pads fitted to all six brake calipers have the same type and grade of pad lining. When fitting new brake pads it will be necessary to press the caliper pistons back into their bores to allow the new brake pads to be inserted. Always ensure that the mineral oil reservoirs do not become overfull with hydraulic mineral oil being returned into the system. Before connecting the electrical cable from the inner brake pad on the front brake calipers, check that the brake pad wear warning circuit is functional. To carry out the check, connect the black/blue cable to the black earth cable. Switch on the ignition and press the footbrake pedal; the brake pad wear warning panel situated on the facia should illuminate. Repeat the test on the other caliper. Fit the road wheels and lower the car. If new brake pads have been fitted, an initial running-in period of between 1100 kilometres and 1300 kilometres (700 miles and 800 miles) should be observed. During this running-in period the brakes should not be applied harshly or for prolonged periods from high speeds except in an emergency. Towards the end of the running-in period, the force with which the brakes are applied may be progressively increased. When the fitting operation has been completed, start and run the engine to pressurize the systems. 9/88 810-2 Switch off the ignition. Apply the footbrake to allow the brake pads to attain their correct positions and remove any excess clearance between the brake pads and the discs. Check the hydraulic system mineral oil level as described under Check the reservoir mineral oil levels and correct if necessary. If an overfull situation is shown the surplus mineral oil should be bled from the system at a brake caliper bleed point. Check the condition of the brake caliper dust excluders (when changing brake pads) The condition of the caliper dust seals should be checked whenever the brake pads are removed. Inspect the seals for signs of damage, heat hardening, or general deterioration and renew if necessary. When fitting new seals, ensure that the seal retaining clips are correctly located. Check the parking brake pads for wear Securely chock the front wheels then raise the rear of the car. Place sill blocks under the rear body sills and also support the rear trailing arms. Do not allow the suspension struts to support the full suspension load. Remove the rear wheels and release the parking brake to the off position. Disconnect the caliper actuation rod from the caliper lever (see fig. B 10-2). Unscrew and remove the caliper adjuster and collect the adjuster clicker plate. Unhook the pad retention spring from each pad, noting the larger spring is fitted to the inner pad. Remove the pads from the caliper. Check the thickness of the lining material on each pad. Pads which are worn to within 1,6 mm (0.062 in} or less of the steel backing plate should be renewed. To fit the pads, attach the retention springs then locate the pads into position and hook the springs onto the caliper. Complete the assembly by reversing the removal procedure, then adjust the calipers as described under the heading Adjust the parking brake calipers and cables. Note If new parking brake pads have been fitted, the following bedding-in procedure should be carried out after adjusting the parking brake. Drive the car at approximately 48 km/h (30 mile/h) and apply the parking brake to bring the car to rest; it is important that this is done gently and progressively. The parking brake must not be applied fully and no attempt should be made to lock the wheels. This operation should be carried out nine times, allowing at least one minute to elapse between stops to prevent the linings overheating. Finally adjust the caliper as described under the heading Adjust the parking brake calipers and cables. Lubricate the parking brake linkage Remove any accumulation of dirt and old grease from the linkage. Renew any worn clevis pins. 9/88 Printed in England © Rolls-Royce Motor Cars Limited 1988 6 5 4 W290 Fig. 810-2 Parking brake mechanism 1 Actuation rod 2 Centralizing straps 3 Parking brake pads 4 Brake disc 5 Adjuster clicker block 6 Adjuster Fig. B10-3 Parking brake adjustment 1 Guide rod and return spring 2 Drive-shaft 3 Actuation lever 4 Suspension strut 5 Brake caliper 6 Actuation rod 7 Caliper adjuster 8 Mounting bracket 9 Spring abutment bracket Lubricate the parking brake linkage clevis pins, fulcrum pins, and the rear cable adjusters with approved grease. TSD 4702 810-3 Adjust the parking brake calipers and cabfes Before any adjustments are made to the parking brake rear cables the caliper on each rear wheel should be set as follows. Remove the clevis pin connecting the brake cable to the actuation lever. Check and adjust if necessary the length of the actuation rod, to obtain a measurement of 63 mm (2.5 in) between the exposed face of the jaw lock-nut and the face of the opposite jaw. Ensure that the parking brake caliper is on its 'off stop'. Check that the clearance (see fig. B 10-3 point A) between the washer on the spring guide rod and the spring abutment bracket is approximately 6 mm (0.250 in) at the point of minimum clearance. Bend the abutment bracket as necessary. Note The washer fitted to the end of the spring guide rod must not act as the parking brake 'off stop' as this will cause caliper pad misalignment. Connect the rear brake cable to the actuation lever. Ensure that the parking brake is in the off position. Adjust the rear cables at the adjusters (see fig. B 10-4) so that the caliper operating levers return to their off-stops under the influence of their return springs with no appreciable slackness in the cables. Note The cables must be adjusted so that the equalizer link on the intermediate linkage (see fig. B 10-41 lies at right angles with the centre line of the car with the parking brake in the off position. To check the cable adjustment, adjust both rear cables at the equalizer Ii nk until the caliper off-stops are just clear of the calipers. Measure the gap produced at each off-stop and lengthen the cables by this amount. With the cables correctly adjusted, check that the centralizing straps (see fig. B 10-2) are pushing the pads away from the discs when the parking brake is in the off position. If not, remove the nut and bolt securing the straps, bend the straps outward (i.e. away from the disc} then refit them. Ensure that the straps are pushed downward towards the adjusting nut Fig. 810·4 Parking brake rear cabfe adjustment point whilst tightening the nut and bolt securing them to the caliper. Check that the distance between the pad and the disc is the same on each side of the caliper; if not, reset the centralizing straps. Raise each rear wheel in turn so that it is free to rotate and adjust each caliper as follows. Turn the caliper adjuster (see fig. B 10-3} clockwise until the pads just grip the disc; at this point it should only just be possible to rotate the road wheel by hand. Turn the adjuster anti-clockwise a quarter turn (i.e. three clicks on the nut) to obtain the minimum clearance between the pads and disc. Check the hydraulic accumulator pressures De pressurize the hydraulic systems as described in TSD 4700 Workshop Manual, Chapter G. Fit a pressure gauge RH9727 into the relevant system service point by means of a suitable high pressure pipe. The service point locations are shown in figure 810-5. Start the engine. The gauge needle should immediately rise to between 31 bar and 62 bar (450 lbf/in2 and 900 lbf/in2} indicating the nitrogen gas pressure in the accumulator sphere. In the event of the gas pressure being below 31 bar (450 lbf/in2) a new sphere should be fitted. If on first starting the engine, the pressure gauge needle fluctuates violently, rapidly climbs to 172 bar (2500 lbf/in2) and then immediately falls to zero on application of the brake pedal, complete loss of nitrogen gas pressure from the accumulator sphere is indicated. After the initial pressure rise the pressure should slowly increase to between 165 bar and 180 bar (2393 lbflin2 and 261 O lbf/in2}. At this pressure the accumulator cut-out valve should actuate and the hydrau lie pump cease to charge the accumulator. After the cut-out pressure has been reached, note the pressure to which the gauge settles. This setting takes up to one minute and the pressure should not be more than 10 bar (150 lbf/in 2 ) below the cut-out pressure. The pressure should then remain steady unless the brake peda I is applied or the level ling system actuated. Fit a bleed tu be onto the bleed screw of the gauge connecting pipe. Open the bleed screw and allow the pressure gauge reading to fall. When the pressure has fallen to between 140 bar and 155 bar (2030 lbf/in2 and 2248 lbf/in2) the accumulator control valve should allow the hydraulic pump to recharge the accumulator. If the cut-in and cut-out pressures of the accumulator are outside the limits quoted the accumulator valve assembly must be renewed. If the pressure continues to fall after the accumulator has reached the cut-out pressure of between 165 bar and 180 bar (2393 lbf/in2 and 2610 I bf/i n2) and then settles, an internal leak is indicated. If observation of the gauge shows that the pump is still pumping (needle fluctuating with the pump pulses) without giving a rise in pressure, then there is a leak equal to the pump flow at that pressure.

The bleed screws are located on each pair of brake calipers (except the rear caliper on the front wheels of cars fitted with anti-lock braking}, on the deceleration conscious pressure limiting valve and on the righthand inner sill from the rear suspension struts. A drain tube is not required at the accumulator bleed screws as these are an integral part of the accumulators and when opened allow the mineral oil to flow from the accumulator spheres back to the reservoirs. Drain the mineral oil from the reservoirs and clean the reservoirs as described in TSD4700 Workshop Manual, Chapter G. After the system has completely drained, close all the bleed screws and ensure that any disturbed pipes are connected and correctly torque tightened. TSO 4702 810-5 Fill the reservoirs with fresh hydraulic system mineral oil (see Chapter A), until the top of the green indicator tube is approximately 3 mm (0.125 in) below the bottom edge of the black ring on the indicator sight glass. Run the engine for approximately four minutes with the car unladen, then top-up the reservoirs until the top of the green indicator tube is up to the top of the black ring on the indicator sight glass. Never allow the mineral oil level to fall below the minimum level (i.e. top of the green indicator tube below the bottom of the indicator sight glass). Check for leaks, especially around all pipes, connections, etc., which have been disturbed. The hydraulic systems must then be bled completely as described in TSD 4700 Workshop Manual, Chapter G. 9/88 B10-6 Section B11 Fuel system Safety precautions It is important that before a fuel line is opened or the fuel tank drained or siphoned, that the workshop safety precautions given in Section 82 are observed. The fuel in the system may be pressurized, except for the fuel tank and return lines. Therefore, it is recommended that the fuel system be depressurized before dismantling any part of the system. To depressurize the system proceed as follows. Clean the inlet connection to the fuel filter. Wrap an absorbent cloth around the joint and carefu Ily slacken the pipe nut to release any pressurized fuel from the system. Tighten the pipe nut. It should be noted that the system will still contain unpressurized fuel. Renew the main fuel filter The main fuel filter is situated on the car underframe (see fig. 811-1 ). The element is housed in a sealed container and no attempt shou Id be made to clean it; always fit a new unit. Place a container beneath the filter to collect any petrol that drains from the filter. Depressu rize the fuel system as described under Safety precautions. Carefully remove the inlet and outlet pipe connections from the filter. Slacken the worm drive clip retaining the filter to the mounting bracket and withdraw the filter. Remove the unions fitted into both ends of the filter and discard the filter. Clean and fit the unions together with new sea Ii ng washers into the new filter. Fit the new tilter by reversing the removal procedure noting the direction of flow arrow marked on the outside of the filter casing. Drain any accumulation of water from the fuel tank Unscrew the union connecting the fuel return line to the fuel distributor. Blow compressed air into the fuel return line to force any fuel in the line into the tank. Slightly jack-up the car on the right-hand side and siphon the fuel from the fuel tank. Lower the jack. Pour 4,5 litres (1 Imp gal, 1.2 US gal} of Exxonva rsol or Shel IM ineral spirit 135 into the fuel tank and rock the car from side to side, to thoroughly mix the spirit with any water remaining in the tank.

To gain access to the battery, turn back the carpet at the right-hand side of the luggage compartment and lift off the battery cover panel. Dependent on the cars specification, either a Chloride 069 low maintenance type or a Delco Freedom maintenance free type 12 volt battery is fitted. Chloride 069 battery Battery electrolyte specific gravity check Remove the vent cover from the top of the battery, ensure the top of the battery is clean prior to removal. Using a hydrometer check the specific gravity of the electrolyte in each cell and compare the readings obtained with the following table. Caution The electrolyte in the battery is a corrosive acid. Do not allow the electrolyte to come into contact with the eyes, skin, fabric, or paintwork. Flush any contacted areas immediately and thoroughly with water. If the eyes are affected, flush for at least 15 minutes and obtain prompt medical attention. Air temperature below32°C (90°F) Specific Gravity 1.270to 1.290 1.180to 1.200 1.090to 1.110 Condition of Battery Fully charged Half discharged Fully discharged Air temperature above 32°C (90°F) Specific Gravity 1.220 to 1.240 1. 150 to 1.170 1.070to 1.090 Condition of Battery Fully charged Half discharged Fully discharged If the specific gravity readings of all the cells are uniform and within the range of 1.240to 1.270the battery is in an acceptable state of charge. If the readings are uniform but below 1.220 the battery should be recharged. Always remove the battery from the car for recharging. If the specific gravity of the electrolyte in one cell differs markedly from the others (i.e. the reading is 0.040 or more, lower than the remainder), then a defect must be suspected and rectified as necessary. Battery electrolyte level check Before correcting the electrolyte level ensure that the battery is in a high state of charge (see Battery electrolyte specific gravity check). The level of the battery electrolyte in each cell should be contacting the indicator bar situated above the separators. If the electrolyte level is low top-up using distilled water until the level is attained. Do not overfill. 9/88 Printed in England © Rolls-Royce Motor Cars Limited 1988 Warning Batteries give off a gas when charging which is flammable and explosive, therefore never bring a naked flame, lighted cigarette, cigar, or pipe near the battery. Always shield the eyes and face from the battery. Delco Freedom battery The top of the battery is sealed and the battery requires no periodic maintenance. However, a temperature compensated hydrometer is built into the top cover of the battery. The hydrometer gives a visual indication of the battery's state of charge. To check the hydrometer first wipe the top of the battery clean. If a green dot is visible in the top of the hydrometer the battery is sufficiently charged. If the top of the hydrometer is dark with no green dot visible, the battery requires charging. Do not charge the battery if the top of the hydrometer is clear or a light yellow colour with no green dot visible. This indicates that the battery requires replacing. Battery voltage check The state of charge of the battery can be checked by taking a voltage reading across the battery terminals using a digital voltmeter or multimeter. The instrument must be accurate to within 0.1 volts. Before a reading is taken on batteries that have recently received a charge, the residual effect of the surface charge on the battery plates must be removed to avoid a false reading. The surface charge can be removed by applying an electrical load to the battery e.g. by connecting a high rate discharge tester for 15 seconds or. if the battery is connected to the car by switching on the headlamps for one minute, before a reading is taken. To ascertain the state of charge of the battery, compare the reading with the following table. Voltage 12.8 volts 12.6 volts 12.5volts 12.4volts State of charge 100% 82% 75% 60% A minimum reading of 12.5 volts (75% charge} is acceptable. Below this reading the battery should be recharged. Clean and check the battery terminals The top of the battery should always be kept clean and dry. If corrosion of the battery leads or terminals has occurred it should be removed as follows. Disconnect the battery leads and using hot water or a dilute solution of ammonia carbonate, wash them thoroughly until all corrosion has been removed. TSD 4702 812-1 Finally wash with clean water to remove the ammonia carbonate solution. Remove any corrosive deposit from the terminal posts using a cloth moistened with ammonia carbonate solution then wash with clean water. Dry the battery leads and terminal posts. Connect the battery leads to the terminal posts. Liberally coat the terminals with petroleum jelly. Check all exterior lamps for operation Actuate the respective switches and check for lamp illumination and function i.e. hazard warning and turn flashers, headlamp dip/main beam, headlamp flash. When checking the fog lamps the main lighting switch must be on. On 1989 model year Bentley four door cars, conforming to a Japanese and USA specification, the front fog lamps are fitted in board of the head lamps. Cars with front fog Iamps fitted In the PARK position the front lamps must be switched on before the rear fog lamps will illuminate. With the main lighting switch in the HEAD position, the fog lamps can be illuminated together or independently. On cars conforming to a Swiss specification, the front and rear fog lamps should only illuminate together when the main lighting switch is in the PARK position. If the switch is turned to the HEAD position, the front fog lamps should extinguish when the headlamps are on dipped beam. When main headlamp beam is selected both front and rear fog lamps should extinguish. Cars without front fog lamps The rear fog lamps will only illuminate when the main lighting switch is in the HEAD position. The respective facia tell-tales should also be checked for illumination during these operations. With the lighting in the PARK and HEAD positions, switch on the ignition. Check the facia instruments for illumination; the panel illumination dimming switch sh ou Id also be checked for correct operation. Dim dip On cars conforming to a United Kingdom specification, the headlamps should illuminate on dipped beam but at a reduced light intensity when the ignition is switched on with the lighting switch in the PARK position. When the lighting switch is turned to the HEAD position, the headlamps should function at full power. Daylight running On 1989 model year cars conforming to a Canadian and Swedish specification, the headlamps should illuminate on dipped beam but at a
