Removal (Fig. 32)
1. Remove the cover plate, gasket and gear case as-
semblyfromtheaxleassembly.Removethegasketand
any remaining gasket material.
2. Remove theretainingrings and thedrivengear from
the input shaft/pinion gear.
3. Remove input shaft/pinion gear assembly from the
gear case. Remove the shims and bearing c ase O-
rings.
4. Release the stake washer and remove the lock nut.
Remove and discard the stake washer.
5. Drive the input shaft/pinion gear out from the outer

NOTE: The bearings must be completely seated.
There should be no input shaft/pinion gear end play.
3. Coat anew oil seal with grease and install as shown
