9. Tighten differential case couple bolts.
10. Place ring gear on differential case and tighten ring gear bolts.
Tighten bolts in a criss-cross pattern, lightly tapping bolt head
with a hammer.
Then bend up lock straps to lock the bolts in place.
11. Install side bearing inner cone.
12. Check differential torque.
AdjustmentNBPD0040For quiet and reliable final drive operation, the following five adjust-
ments must be made correctly:
1. Side bearing preload
2. Pinion gear height
3. Side bearing preload
4. Ring gear-to-pinion backlash. Refer to SDS, PD-62.
5. Ring and pinion gear tooth contact pattern

PINION GEAR HEIGHTNBPD0040S011. Make sure all parts are clean and that the bearings are well
lubricated.
2. Assemble the pinion gear bearings into the pinion pre-load
shim selector tool, J34309.

IRear Pinion BearingÐ the rear pinion bearing pilot,
J34309-8, is used to center the rear pinion bearing only. The
rear pinion bearing locking seat, J34309-4, is used to lock the
bearing to the assembly.
IFront Pinion BearingÐ make sure the J34309-3, front pin-
ion bearing seat is secured tightly against the J34309-2 gauge
anvil. Then turn the front pinion bearing pilot, J34309-5, to
secure the bearing in its proper position.

3. Place the pinion preload shim selector tool gauge screw
assembly, J34309-1, with the pinion rear bearing inner cone
installed, into the final drive housing.
