c. Measure turning torque of final drive assembly.
Turning torque of final drive assembly (New bearing):
Refer to SDS, MT-121.
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 N·m (10 kg-cm, 8.7 in-lb)
without binding.
Mainshaft Bearing PreloadNJMT0091S02If any of the following parts are replaced, adjust mainshaft bearing
preload.
Mainshaft

1. Remove case cover, O-ring, spacer, mainshaft rear bearing
adjusting shim and mainshaft rear bearing outer race from
transmission case.
2. Install mainshaft assembly on clutch housing.
3. Install transmission case on clutch housing.

4. Install mainshaft rear bearing outer race on inner race.
SMT599
5. Measure distance (“”) from transmission case to bearing outer
race.
Make sure that bearing is properly seated.
6. Select shim considering bearing preload.
Suitable shim thickness = measure distance (“”) − 12.5 mm
(0.492 in) + (specified bearing preload)
Mainshaft rear bearing preload and adjusting shims:
Refer to SDS, MT-121.
7. Check total turning torque after assembling. Refer to
“ASSEMBLY”, MT-51.
