Fiat 126 / 5 00 Motomax driveshaft mounting instruction. ©motomax.pl The single-side (set half) contains with: Interconnecting axle with inner tripod joint and outer B-F cv joint, sideplate with bearing, stub axle, seal, seeger circlip, outer joint’s boot clamps, grease and nyloc nut. • Dismount the differential mechanism with half-shafts from the gearbox body. • Disassemble the differential mechanism, and remove the half-shafts with the “stones”. • Introduce the stub axles into the differential side (crown) gears. • Assemble the differential casing with original bearing covers. • Regulate precisely the side bearing tension and final drive clearance. (!!!) • Install the side bearing carriers (included in the set). - Take an attention to the o-ring position (!), and screw tight the M6 bolts. • Pull out the stub axle, using the hole in the splined end. Fix the stub axle in the right position by seeger circlip. • Place the seal rings in the side plates casing. • Repeat the stub axle installation process for other side of the car. • Install the joint housing on to the splined part of the stub axle. You may have to tap it on with a hammer. • Attach the joint housing to the stub axle using the provided 27mm nyloc self-locking nut. Apply the nyloc nut with the locking ring FIRST! (opposite to standard use). • Tighten the nut to the factory recommended torque. Be sure to check the bearing preload and make sure the axle rotates freely. • Check the rubber damper is placed in the hole at the end of the axle shaft. • Fill up the joint housing with a half of the grease volume, and introduce the joint ball-cage into the housing. • Install the wire ring into the channel inside the joint housing to keep the ball-cache on place. • Install the inner joint of the driveshaft onto the gearbox stub axle, pulling the joint to outside direction. (There is a spring inside the joint). • Fill the joint housing and the cv joint boot with second half of grease. • Slide the rubber boot onto outer joint. • Place one end of the wire clamp ring onto the clamp place, and using the small clamp as a guide, rotate the axle until the wire ring is completely on place . This will install the wire ring without damaging the rubber boot. • Close the shaft side of the joint boot with a universal clamp. • Repeat the joint installation process for other side of the car. This completes the installation.
