Adjustment

Input Shaft End Play and Differential Side Bearing Preload
If any of the following parts are replaced, adjust input shaft end play.
- Input shaft
- Input shaft bearing
- Clutch housing
- Transmission case

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. Reinstall differential side bearing outer race without shim(s).
3. Install input shaft and final drive assembly on clutch housing.
4. Install transmission case without input shaft bearing shim(s). Then tighten it to the specified torque. Refer to Manual Transmission/Transaxle; Service and Repair; Transaxle Overhaul; Major Overhaul.
5. Using the following procedures, measure clearance between bearings and transmission case.
- Differential side





a. Attach dial indicator. If clamp diameter of dial indicator is too small or too large, attach dial indicator using a magnetic stand.





b. Insert Tool all the way into differential side gear. Move Tool up and down and measure dial indicator deflection.





- Input shaft side
a. Set dial indicator on end of input shaft.
b. Move input shaft up and down and measure dial indicator deflection.
6. Select shims with proper thickness with SDS table as a guide. Refer to Application and ID.
7. Install selected differential side bearing adjusting shim and differential side bearing outer race.
8. 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 Manual Transmission/Transaxle; Service and Repair; Transaxle Overhaul; Major Overhaul.





c. Measure turning torque of final drive assembly.
Turning torque of final drive assembly (New bearing): 4.9 - 7.8 Nm (50 - 80 kg.cm, 43 - 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.

Mainshaft Bearing Preload
If any of the following parts are replaced, adjust mainshaft bearing preload.
- Mainshaft
- Mainshaft bearings
- Clutch housing
- Transmission case





1. Remove mainshaft rear bearing outer race and shim(s).





2. Reinstall mainshaft rear bearing outer race without shims.
3. Clean mating surfaces of clutch housing and transmission case with solvent.
4. Install mainshaft and mainshaft front bearing outer race into transmission case. Turn mainshaft while holding bearing outer race so that bearings are properly seated.





5. Place Tools (bridge and gauging cylinder) onto machined surface of transmission case. Allow gauging cylinder to rest on surface of mainshaft front bearing outer race. Use proper screw in bridge to lock gauging cylinder in place.





6. Turn bridge over and place Tool (gauging plunger) into gauging cylinder.





7. Place bridge, legs up, onto machined surface of clutch housing. Allow gauging plunger to rest upon mating surface where mainshaft front bearing outer race fits.








8. Measure with feeler gauge distance between gauging cylinder and shoulder of gauging plunger.
9. Use feeler gauge reading to select correct mainshaft preload shim(s).
Mainshaft bearing adjusting shim: Refer to Application and ID.
10. Install selected mainshaft bearing adjusting shim and mainshaft bearing outer race.
11. Check total turning torque after assembly. Refer to ASSEMBLY.
