22. Place a pinion nut on the pinion, torque the
pinion nut to a minimum of 200 ft. lbs. (Figure
37).
NOTE: If the bearings are being reused, follow
the same process as above, except the pinion
torque-to-rotate must be set at 1 to 2 in. lbs.
over the pinion torque-to-rotate obtained during
teardown. The bearings are already broken in, so
setting a used bearing to a torque meant for a
new bearing will cause the old bearing to fail
prematurely.
Differential Case Disassembly
1. Remove the differential bearings using a Miller
puller set number C-293-PA and inserts 8353
(Figure 39).
NOTE: There is no set maximum torque because
each spacer collapses differently. Once the
spacer starts to collapse, continue checking for
25 to 35 in. lbs. torque to rotate using a 50 in.
lb. wrench.
23. Turn the torque wrench four revolutions,
taking a reading while the wrench is moving on
the fourth turn.
NOTE: Be sure to inspect the bearings for
damage that could cause bearing failure.
Also, look at the differential case bearing trun-
nions for signs of damage (Figure 40).
24. Tighten the pinion nut slowly, checking the
torque-to-rotate often (Figure 38).
NOTE: It is important that the maximum pinion
torque- to- rotate is not exceeded. However, a
minimum torque to rotate of 25 in. lbs. must be
met. The pinion preload is now set. Be sure to write
down this number because it will be needed later.
