Output Shaft Bearing Preload

1. Select proper thickness of output shaft bearing adjusting spacer using the following procedures.
a. Remove paper rolled around output shaft.
b. Place bearing retainer on output shaft.




c. Place output gear bearing inner race on bearing retainer.
d. Measure dimensions "G" and "H" and calculate dimension "F".

"F": Distance between the surface of output gear bearing inner race and adjusting shim mating surface of output shaft.

F = H - G




- Measure dimension "G" between end of output shaft and surface of output gear bearing inner race.
- Measure in at least two places.




- Measure dimension "H" between end of output shaft and adjusting spacer mating surface of output shaft.
- Measure in at least two places.
- Calculate dimension "F".

F = H - G




e. Measure distance "I" between end of output gear (adjusting spacer mating surface) and bearing inner race fitting surface.
f. Calculate dimension "T(2)".

"T(2)": Distance between adjusting spacer mating surface of output gear and output shaft
T(2) = F - I

g. Select proper thickness of output shaft bearing adjusting spacer using SDS table as a guide.




2. Install bearing retainer on transmission case.




3. Place output shaft on bearing retainer.
4. Place output shaft bearing adjusting spacer selected in step 1 - g on output shaft.
5. Press output gear bearing inner race on output gear.
6. Press output gear on output shaft.




7. Tighten output gear lock nut to specified torque




8. Remove idler gear to measure output shaft preload.




9. Measure turning torque of output shaft.
- When measuring turning torque, turn output shaft in both directions several times to seat bearing rollers correctly.

Turning torque of output shaft: 0.25 - 0.88 N.m (2.5 - 9.0 kg-cm, 2.2 - 7.8 in-lb)




10. Install idler gear and tighten lock nut to specified torque.
11. After properly adjusting "turning" torque, clinch idler gear and output gear lock nuts as shown.




12. Install new gasket and side cover on transmission case.
