Adjustment

ADJUSTMENT
Differential Side Bearing Preload
If any of the following parts are replaced, adjust differential side bearing preload.
- Differential case
- Differential side bearing
- Clutch housing
- Transmission case





1. Remove differential side bearing outer race (transmission case side) and shim(s).





2. Install differential side bearing outer race without shim(s).
3. Install final drive assembly on clutch housing.
4. Install transmission case on clutch housing.
- Tighten transmission case fixing bolts to the specified torque.





5. Set dial indicator on front end of differential case.
6. Insert Tool all the way into differential side gear.
7. Move Tool up and down and measure dial indicator deflection.
8. Select shim considering bearing preload.
- Suitable shim thickness = Dial indicator deflection + specified bearing preload
- Differential side bearing adjusting shims and preload: Refer to Application and ID.
9. Install selected shim(s) and differential side bearing outer race.





10. Check differential side bearing turning torque.
a. Install final drive assembly on clutch housing.
b. Install transmission case on clutch housing.
- Tighten transmission case fixing bolts to the specified torque.
c. Measure turning torque of final drive assembly.
Turning torque of final drive assembly (New bearing): 2.0 - 7.8 Nm (20 - 80 kg.cm, 17 - 69 inch lbs.)
- When old bearing is used again, turning torque will be slightly less than the above.
- Make sure torque is close to the specified range.
- Changes in turning torque of final drive assembly per revolution should be within 1.0 Nm (10 kg.cm, 8.7 inch lbs.) without binding.
Mainshaft Bearing Preload
If any of the following parts are replaced, adjust mainshaft bearing preload.
- Mainshaft
- Mainshaft bearings
- Clutch housing
- Transmission case





1. Remove case cover, O-ring, mainshaft bearing adjusting shim, spacer and mainshaft rear bearing outer race from transmission case.
2. Install mainshaft assembly on clutch housing.
3. Install transmission case on clutch housing.
- Tighten transmission case fixing bolts to the specified torque.





4. Install mainshaft rear bearing outer race on inner race.





5. Measure distance from transmission case to bearing outer race.
- Make sure that bearing is properly seated.
6. Select shim. Refer to Application and ID.
7. Check total turning torque after assembling.
