DRIVE PINION AND RING
GEAR SET
When replacing a ring gear and
pinion, note that the original factory
insta\led (pinion locating) shim is o1
the correct thickness to adjust for
individual variations in both the car--
rier housing dimension and in the
original gear set dimension. There-
fore, to select the correct shim thick-
ness for the new gear set to he in-
stalled, follow these steps:
1. Measure the thickness of the
original pinion locating shim with
a micrometer.
2. Note the shim adjustment num-
ber on both the old pinion and the
new pinion. Each pinion gear is
marked with an
adju~tmcnt
number
such as the ·~·I marking in Fig. 24.
3. Refer to the tahle in Part 4-3
for the correct amount of shim thick-
ness change. The amount that is
shown under the new pinion shim
adjustment number and in line with
the old pinion number is the amount
of change that should be made to
the original shim thickness.
If the old pinion is marked +4,
for example, and the new pinion is
marked -2, the table indicates that
0.006 inch of shim stock should be
added to the original shim pack.
If the original shim pack was lost
or if a new axle housing is being in-
stalled, substitute a nominal 0.030
inch shim for the original, and re-
peat the foregoing steps for a trial
huild-up. If any further shim change
is necessary, it will be indicated in
the tooth pattern check.
A new ring gear and pinion
should always be installed in an
