- ring gear bearing housing nuts
- ring gear bearing housing bolts
Note: Working in a crisscross pattern, loosen each nut 1/4 of a turn. After all of the nuts are fully loosened, remove them and the bolts.
2. Remove:
- ring gear bearing housing (1)
- ring gear (2)
- thrust washer (3)
- ring gear shim(-s) (4)
3. Adjust: ring gear backlash
a. Use the following chart to select the suitable shim(-s) and thrust washer.
- Thinner shim: Ring gear backlash is increased.
- Thicker shim: Ring gear backlash is decreased.
b. If it is necessary to increase the ring gear backlash by more than 0.2 mm, reduce the thrust washer thickness by 0.2 mm for every 0.2 mm increase of ring gear shim thickness.
c. If it is necessary to reduce the ring gear backlash by more than 0.2 mm, increase the thrust washer thickness by 0.2 mm for every 0.2 mm decrease of ring gear shim thickness.
- Rig gear shims: Thickness (mm): 0.25, 0.30, 0.40
- Thrust washers: Thickness (mm): 1.2, 1.4, 1.6, 1.8, 2.0
