Differential Side Bearing Preload

1. Install differential side bearing outer race without adjusting shim on transmission case.
2. Install differential side bearing outer race on converter housing.




3. Place final drive assembly on transmission case.
4. Install transmission case on converter housing and tighten transmission case fixing bolts to the specified torque.




- RE4F04A -
5. Attach dial indicator on differential case at converter housing side.
6. Insert Tool into differential side gear from transmission case side.
7. Move Tool up and down and measure dial indicator deflection.




- RE4F04V -
5. Set Tool on differential case at converter housing side and attach dial indicator on Tool.
6. Insert the other Tool viscous coupling from transmission case side.
7. Move Tool up and down and measure dial indicator deflection.

- RE4F04A and RE4F04V -
8. Select proper thickness of differential side bearing adjusting shim(s).

Suitable shim thickness = Dial indicator deflection + Specified bearing preload

Bearing preload: 0.05 - 0.09 mm (0.0020 - 0.0035 in)

9. Remove converter housing from transmission case.
10. Remove final drive assembly from transmission case.
11. Remove differential side bearing outer race from transmission case.
12. Reinstall differential side bearing outer race and shim(s) selected from SDS table on transmission case.
13. Reinstall converter housing on transmission case and tighten transmission case fixing bolts to the specified torque.




14. Insert Tool into viscous coupling and measure turning torque of final drive assembly.
- When measuring turning torque, turn final drive assembly in both directions several times to seat bearing rollers correctly.

Turning torque of final drive assembly (New bearing): 0.78 - 1.37 N.m (8.0 - 14.0 kg-cm, 6.9 - 12.2 in-lb)

- When old bearing is used again, turning torque will be slightly less than the above.
- Make sure torque is close to the specified range.
