CV Boot - Inner

CV BOOT - INNER

REMOVAL
1. Remove large boot clamp which retains inner tripod joint sealing boot to tripod joint housing and discard. Remove small clamp which retains inner tripod joint sealing boot to interconnecting shaft and discard. Remove the sealing boot from the tripod housing and slide it down the interconnecting shaft.

CAUTION: When removing the tripod joint housing from the spider assembly, hold the bearings in place on the spider trunnions to prevent the bearings from failing away.





2. Slide the tripod joint housing off the spider assembly and the interconnecting shaft (Fig. 22).








3. Remove snap ring which retains spider assembly to interconnecting shaft (Fig. 23). Remove the spider assembly from interconnecting shaft. If spider assembly will not come off interconnecting shaft by hand, it can be removed by tapping spider assembly with a brass drift (Fig. 24). Do not hit the outer tripod bearings in an attempt to remove spider assembly from interconnecting shaft.
4. Slide sealing boot off interconnecting shaft.
5. Thoroughly clean and inspect spider assembly, tripod joint housing, and interconnecting shaft for any signs of excessive wear. If any parts show signs of excessive wear, the driveshaft assembly will require replacement. Component parts of these driveshaft assemblies are not serviceable.

INSTALLATION





1. Slide inner tripod joint seal boot retaining clamp, onto interconnecting shaft. Then, slide the replacement inner tripod joint sealing boot onto the interconnecting shaft. Inner tripod joint seal boot MUST be positioned on interconnecting shaft, so the raised bead on the inside of the seal boot is in groove on interconnecting shaft (Fig. 25).








2. Install spider assembly onto interconnecting shaft (Fig. 26). Spider assembly must be installed on interconnecting shaft far enough to fully install spider retaining snap ring. If spider assembly will not fully install on interconnecting shaft by hand, it can be installed by tapping the spider body with a brass drift (Fig. 27). Do not hit the outer tripod bearings in an attempt to install spider assembly on interconnecting shaft.





3. Install the spider assembly to interconnecting shaft retaining snap ring into groove on end of interconnecting shaft (Fig. 28). Be sure the snap ring is fully seated into groove on interconnecting shaft.
4. Distribute 1/2 the amount of grease provided in the seal boot service package (DO NOT USE ANY OTHER TYPE OF GREASE) into tripod housing. Put the remaining amount into the sealing boot.





5. Align tripod housing with spider assembly and then slide tripod housing over spider assembly and interconnecting shaft (Fig. 29).

6. Install inner tripod joint seal boot to interconnecting shaft clamp evenly on sealing boot.








7. Clamp sealing boot onto interconnecting shaft using crimper, Special Tool C-4975-A and the following procedure. Place crimping tool C-4975-A over bridge of clamp (Fig. 30). Tighten nut on crimping tool C-4975-A until jaws on tool are closed completely together, face to face (Fig. 31).

CAUTION: Seal must not be dimpled, stretched or out of shape in any way. If seal is NOT shaped correctly, equalize pressure in seal and shape it by hand.

8. Position sealing boot into the tripod housing retaining groove. Install seal boot retaining clamp evenly on sealing boot.

CAUTION: This positioning procedure determines the correct air pressure inside the inner tripod joint assembly prior to clamping the sealing boot to inner tripod joint housing. If this procedure is not done prior to clamping sealing boot to tripod joint housing sealing boot durability can be adversely affected.

CAUTION: When venting the inner tripod joint assembly, use care so inner tripod sealing boot does not get punctured, or in any other way damaged. If sealing boot is punctured, or damaged in any way while being vented, the sealing boot can not be used.





9. Insert a trim stick between the tripod joint and the sealing boot to vent inner tripod joint assembly (Fig. 32). When inserting trim stick between tripod housing and sealing boot ensure trim stick is held flat and firmly against the tripod housing. If this is not done damage to the sealing boot can occur. If inner tripod joint has a Hytrel (hard plastic) sealing boot, be sure trim stick is inserted between soft rubber insert and tripod housing not the hard plastic sealing boot and soft rubber insert.
10. With trim stick inserted between sealing boot and tripod joint housing, position the interconnecting shaft so it is at the center of its travel in the tripod joint housing. Remove the trim stick from between the sealing boot and the tripod joint housing. This procedure will equalize the air pressure in the tripod joint, preventing premature sealing boot failure.
11. Position trilobal boot to interface with the tripod housing. The lobes of the boot must be properly aligned with the recess's of the tripod housing.
12. Clamp tripod joint sealing boot to tripod joint, using required procedure for type of boot clamp application.

CRIMP TYPE BOOT CLAMP
If seal boot uses crimp type boot clamp:
^ Clamp sealing boot onto tripod housing using Crimper, Special Tool C-4975-A.





^ Place crimping tool C-4975-A over bridge of clamp (Fig. 33).





^ Tighten nut on crimping tool C-4975-A until jaws on tool are closed completely together, face to face (Fig. 34).

LATCHING TYPE BOOT CLAMP
If seal boot uses low profile latching type boot clamp:
^ Clamp sealing boot onto tripod housing using clamp locking tool, Snap-On YA3050 or an equivalent.





^ Place prongs of clamp locking tool in the holes of the clamp (Fig. 35).





^ Squeeze tool together until top band of clamp is latched behind the two tabs on lower band of clamp (Fig. 36).
