Tripot Housing/Tripot Seal Replacement

Figure 10 - Inboard Joint Disassembly:

Required Tools:

J8059 Snap Ring Pliers J35910 Seal Clamp Tool

1. Place halfshaft in vise (use protective covers over vise jaws).

2. Remove seal clamp protectors (Figure 10) if used, from inner C/V joint and cut clamp(s) from seal with a pair of side cutters. For swage ring removal use a hand grinder to cut through the ring (taking care not to damage the housing).

3. Remove tripot housing from halfshaft and wipe grease from tripot assembly roller bearings and housing. Thoroughly degrease the housing and allow to dry prior to assembly.

Important: Handle tripot spider assembly with care. Tripot balls and needle rollers may separate from spider trunnions.

4. Slide seal up on the shaft and inspect rollers, needle bearings, and trunnions. Check housing for unusual wear, cracks, and other damage. Replace housing and/or tripot assembly as needed.

Figure 11 - Snap Ring and Spider Removal:

5. To remove the spider assembly (also required for seal replacement), spread the spacer ring with tool J8059 or equivalent and slide the ring and spider assembly up on the shaft (Figure 11). This will provide access to the shaft retaining ring in the groove at the end of the shaft. Remove the retaining ring, spider assembly, spacer ring, and seal.

Figure 12 - Small Retaining Clamp Installation:

6. Clean the shaft. If rust is present in the seal mounting area (grooves), wire brush this area (Figure 12).

7. Slide the new small seal clamp and seal onto the shaft to the proper position.

8. Secure the clamp with tool J35910, breaker bar and torque wrench. Torque small clamp to 136 N-m (100 lbs.ft.). Check clamp ear gap dimension (Figure 12).

Figure 13 - Proper Inboard Stroke Positioning:

9. Install convolute retainer over seal capturing four convolutes (Figure 13).

Important: Joint must be assembled with convolute retainer in position as shown in Figure 13. Seal damage will result if joint is not assembled to dimension shown.

Figure 14 - Spider Assembly Installation:

10. Install spacer ring and spider assembly (with counterbore toward end of shaft) on the shaft far enough to allow installation of the retaining ring at the end of the halfshaft (Figure 14).

11. Install the retaining ring and push the spider assembly toward the end of the shaft until retaining ring is covered by the spider assembly counterbore. Install the spacer ring and make sure it is seated in its groove.

12. Pack the seal and housing with grease supplied in the kit, (the amount of grease supplied in this kit has been premeasured for this application), place the large metal clamp on the seal, then place the housing over the spider assembly and snap the seal onto the housing.

Figure 15 - Large Retaining Clamp Installation:

13. Secure the large metal clamp and seal to the housing with tool J35910, breaker bar and torque wrench. Torque the large clamp to 176 N-m (130 lbs.ft.). Check clamp ear gap dimension (Figure 15).
