(3) Assembly
NOTE: When the drive pinion and ring gear are
reused, assemble using the same shims as
removed. When the drive pinion and ring
gear are replaced, adjust the shims as
described below. The ring gear and pinion
are serviced only as a matched set and
must be replaced together.
If the drive pinion and ring gear are replaced:
The drive pinion and ring gear are identified by an
assembly number which is stamped into the end of the
drive pinion gear and on the circumference of the ring gear.
In addition, a “Value of Error” number is also stamped into
the end of the pinion gear.
The tolerance value is no stamped when the tolerance is
zero. This number is prefixed with a (+) or (-) to indicate
the amount of error from zero adjustment. If the value of
error is greater on the new pinion than on the old pinion,
additional shims will be required. If the value of error is
less on the new pinion than on the old pinion, the number
of shims must be decreased.
Example:
Replaced pinion ·················································· -0.2 mm
New pinion ························································· ±0.0 mm
-0.2 + 0.0 = -0.2
Decrease the shims by 0.2 mm
(4) Differential ring Gear and Pinion Assembly
1. Assemble the differential pinion shaft, pinion gears,
thrust washers dowel pins and side gears as shown,
Figure 370X.
2. Install the ring gear on the case and tighten new bolts
and additional lock washers to the specified torque.
3. Bend the tabs to secure the bolts.
4. If removed, install the two drive pinion bearings in the
housing.
5. Assemble the thrust washer, shims and pinion shaft
front bearing on the shaft. Insert the pinion shaft into
the housing from the front while installing the rear
bearing, fixed gear, washer and lock nut as shown.
