The following procedures assume the rear axle assembly<br />
has been removed from the machine (see Rear Axle<br />
Assembly Removal in this section).<br />
Removal (Fig. 30)<br />
1. Remove the cover plate, gasket and gear case assembly<br />
from the axle assembly. Remove the gasket and<br />
any remaining gasket material.<br />
2. Remove the retaining rings and the driven gear from<br />
the input shaft/pinion gear.<br />
3. Remove input shaft/pinion gear assembly from the<br />
gear case. Remove the shims and bearing case O-<br />
rings.<br />
4. Release the stake washer and remove the locknut.<br />
Remove and discard the stake washer.<br />
5. Drive the input shaft/pinion gear out from the outer<br />
bearing cone and bearing case. Remove and discard<br />
the oil seal and O-ring.<br />
Installation (Fig. 30)<br />
NOTE: When installing new bearing cones, press only<br />
on the inner race of the bearing cone.<br />
1. If the inner bearing cone was removed, press a new<br />
bearing cone all the way onto the input shaft/pinion gear.<br />
2. Place the shaft and bearing assembly in the bearing<br />
case and install the outer bearing cone.<br />
NOTE: The bearings must be completely seated.<br />
There should be no input shaft/pinion gear end play.<br />
3. Coat a new oil seal with grease and install as shown<br />
(Fig. 31). The seal should be installed with the garter<br />
spring towards the hydraulic motor.<br />
4. Coat new O-ring with grease. Install O-ring in the oil<br />
seal collar and install the collar.<br />
5. Install a new stake washer. Install the lock nut finger<br />
tight.<br />
6. Inspect all gears, shafts, bearings, spacers and<br />
cases for damage and wear. Replace components as<br />
necessary.<br />
NOTE: Replacement input shaft/pinion gears are only<br />
available in matched ring and pinion sets.<br />

6. Set the bearing preload by securing the bearing case<br />
in a vise. Thread a M12 x 1.5 hex head cap screw into<br />
the splined end of the input shaft/pinion gear and slowly<br />
tighten the locknut until 4to6in-lb(0.4to0.7N-m)of<br />
force is required to rotate the input shaft/pinion gear in<br />
the bearing case.<br />
