INSPECTION
Gear, Washer, Shaft and Case
lCheck mating surfaces of differential case, side gears and pin-
ion mate gears.
lCheck washers for wear.
Bearings
lMake sure bearings roll freely and are free from noise, cracks,
pitting or wear.
lWhen 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.
lWhen 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.
4. Install lock pin.
lMake sure that lock pin is flush with case.

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 toAT-
461, "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
shim(s).
Suitable shim thickness = Dial indicator deflection + Speci-
fied bearing preload

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-461, "
OVERHAUL".
14. Insert Tool and measure turning torque of final drive assembly.
lTurn final drive assembly in both directions several times
to seat bearing rollers correctly.
lWhen old bearing is used again, turning torque will be
slightly less than the above.
lMake sure torque is close to the specified range.
REDUCTION PINION GEAR BEARING PRELOAD
1. Remove transmission case and final drive assembly from con-
verter housing.
2. Select proper thickness of reduction pinion gear bearing adjust-
ing shim using the following procedures.
