2. If the bearing cup (23) was removed, press new
bearing cup into the carrier assembly (15) (Fig. 35).
3. If the bearing cup (10) was removed, place shims
(14) into the carrier assembly (15). Press new bearing
cup into the assembly (Fig. 36).
4. If a new carrier assembly (15) is being installed, pro-
ceed as follows:
A. Press bearing cup (10) into the assembly with out
any shims (14).
B. Place pinion gear (8) with bearing cone (9)
installed into the carrier assembly and bearing cup.
C. Measure and note distance from the centerline of
the ring gear to the bottom of the pinion gear teeth us-
ing a depth micrometer (Fig. 32 and 37).
D. Note shimming dimension on the pinion gear
(Fig. 33). If the dimension is (+) positive, add the di-
mension to 3.750 inch. If the dimension is (–) nega-
tive, subtract the dimension from 3.750 inch.
For Example: If the pinion gear shaft is 4.
Add 0.004 to 3.750 to get 3.754 inch. If the pinion
gear shaft is etched –4. Subtract 0.004 from 3.750 to
get 3.746 inch.
E. Now determine the difference between the mea-
surement taken in a step C and the value calculated
in step D. This difference is the
new shim thickness.
F. Remove bearing cup from the carrier assembly.
G. Install required shim thickness and bearing cup
into the carrier assembly.
IMPORTANT: The pinion gear (8) and ring gear (32)
are supplied only as a matched set. Matching num-
bers on both gears are etched for verification. When
using a new gear set, make sure the matching num-
bers are verified before using (Fig. 33).
5. Install pinion gear (8) and bearing cone (9) into the
carrier assembly (15). Place bearing spacer (24), shims
(21), and bearing cone (22) on to the shaft of the pinion
gear (Fig. 38).
