1. Remove transmission case while slightly tilting it to prevent 5th
shift fork from interfering with case.
SMT188A
2. Draw out reverse idler spacer and fork shaft, then remove 5th
and 3rd & 4th shift forks.
Be careful not to lose shifter cap.
SMT082A
3. Remove control bracket with 1st & 2nd shift fork.
Be careful not to lose shifter cap.
SMT577
4. Remove gear components from clutch housing.
a. Remove three screws and detach bearing retainer.
One of these three screws is torx type and should be
removed with a suitable tool, as shown.
SMT579
b. Remove input shaft together with mainshaft by tapping lightly.
Always withdraw mainshaft straight out. Failure to do so
can damage resin oil channel on clutch housing side.
Do not draw out reverse idler shaft from clutch housing
because these fittings will be loose.
When removing input shaft, be careful not to scratch oil
seal lip with shaft spline.

2. Reinstall 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. Refer to MT-30.
SMT454-A
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 preload and adjusting shims:
Refer to SDS, MT-121, MT-122.
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. Refer to MT-30.

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.

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.
Tighten transmission case fixing bolts to the specified
torque. Refer to MT-30.
SMT650A
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.

15. Measure total turning torque.
Total (Final drive + Mainshaft) turning torque (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.
