Shimming Procedure/Shim Selection
It is very important to adjust bevel gears for the proper
running tolerances. Gear life and gear noise are greatly
affected by these tolerances; therefore, it is very import-
ant to properly adjust any gear set prior to final assembly.
The following procedure can be used on both front differ-
ential or rear drive gear case.
NOTE: All bearings must be installed in the gear
case and the pinion properly installed before proceed-
ing.
Backlash
NOTE: Always set backlash prior to any other
shimming.
1. Install the existing shim or a 0.051-0.055-in. shim on
the gear case side of the ring gear assembly.

2. Install the ring gear with shim in the gear case; then
while holding the pinion stationary, rock the ring
gear forward and back to determine if any backlash
exists. If no backlash exists, install a thicker shim
and recheck.
GC036A
3. Install the existing shim or a 0.063 in. shim on the
cover side of the ring gear; then place the assembled
gear case cover onto the gear case and secure with
three cap screws. Tighten evenly using a crisscross
pattern.

4. Place the appropriate Backlash Measuring Tool into
the splines of the ring gear and install a dial indicator
making sure it contacts the gauge at a 90° angle and
on the index mark.
