Tool Part Number Part Description Qty
A 1P-0520 Driver Group 1
B 1U-8605 Seal Guide 1
C 1P-0510 Driver Group 1 Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement.
Illustration 1 g00667833
Use tooling (A) and a suitable press to install bearing cup (13).
Illustration 2 g00667834
Use tooling (A) and a suitable press to install bearing cup (12).
Illustration 3 g00667836
Use tooling (B) and a suitable press, to install bearing cone (11) to shaft (10).
Illustration 4 g00667837
Install shaft assembly (10). Install bearing cone (9). Leave slight bearing end play.
Clean mating surfaces of the pinion housing and the retainer. Apply a continuous bead of 1U-8846 Sealant, as shown.
Illustration 5 g00667852
Use tooling (C) to install seal (8) in retainer (7).
Illustration 6 g00667840
Install the spacer (not shown) on top of bearing cone (9). Use six bolts (6) to install retainer (7).
Illustration 7 g00667841
Place the pinion assembly in a holding fixture. Install yoke assembly (5), shim pack (3), and seal (4).
Illustration 8 g00667842
Install retainer (2), and bolt (1). The torque for bolt (1) is 105 20 N m (75 15 lb ft).Note: The following measurements include seal drag.
Secure the pinion housing in a holding fixture. Use a torque wrench to check the rolling torque on bolt (1). The rolling torque must be 1.3 to 2 N m (11.5 to 17.7 lb in) for new bearings. The torque for used bearings should be .9 to 1.3 N m (7.9 to 11.5 lb in).
If the rolling torque exceeds the specification in Step 10, then increase the number of shims in Step 8.
If the rolling torque does not meet the specification in Step 10, then reduce the number of shims in Step 8.End By:
Install the differential and bevel gear. Refer to Disassembly and Assembly, "Differential and Bevel Gear - Install".
