Installation (Fig. 32)
NOTE: When installing new bearing cones, press only
on the inner race of the bearing cone.
1. If the inner bearing cone was removed, press a new
bearing cone all the way onto the input shaft/pinion gear.
2. Place the shaft and bearing assembly in the bearing
case and install the outer bearing cone.
NOTE: The bearings must be completely seated.
There should be no input shaft/pinion gear end play.
3. Coat a new oil seal with grease and install as shown
(Fig. 33). The seal should be installed with the garter
spring towards the hydraulic motor.
4. Coat new O-ring with grease. Install O-ring in the oil
seal collar and install the collar.
5. Install a new stake washer. Install the lock nut finger
tight.
6. Set the bearing preload by securing the bearing case
in a vise. Thread a M12 x 1.5 hex head cap screw into
the splined end of the input shaft/pinion gear and slowly
tighten the lock nut until 4 to 6 in-lb (0.4 to 0.7 N- -m) of
force is required to rotate the input shaft/pinion gear in
the bearing case.
