INSPECTION
Gear, Washer, Shaft and Case
●Check mating surfaces of differential case, side gears and pin-
ion mate gears.
●Check washers for wear.
Bearings
●Make sure bearings roll freely and are free from noise, cracks,
pitting or wear.
●When replacing taper roller bearing, replace outer and inner
race as a set.

ASSEMBLY
1. Attach side gear thrust washers to side gears, then install pinion
mate thrust washers and pinion mate gears in place.
2. Insert pinion mate shaft.
●When inserting, be careful not to damage pinion mate
thrust washers.
3. Measure clearance between side gear and differential case with
washers following the procedure below:
a. Set Tool and dial indicator on side gear.
b. Move side gear up and down to measure dial indicator deflec-
tion. Always measure indicator deflection on both side gears.
c. If not within specification, adjust clearance by changing thickness of differential side gear thrust washers.

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. Tighten trans-
mission case fixing bolts to the specified torque. Refer to AT-
421, "OVERHAUL" .
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.
8. Select proper thickness of differential side bearing adjusting

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. Refer to
AT-421, "

14. Insert Tool and measure turning torque of final drive assembly.
●Turn final drive assembly in both directions several times
to seat bearing rollers correctly.
●When old bearing is used again, turning torque will be
slightly less than the above.
●Make sure torque is close to the specified range.
