11.
Install the roller bearing and new lock nut on
the carrier shaft. Torque tighten the nut but do
not lock (peen) the nut to the shaft (see torque
specifications).
12.
Perform the planetary gear carrier height
adjustment as follows:
a. Reassemble the final drive half-cases
leaving the differential ring and pinion
assembly out of the case. Torque tighten
case bolts (see torque specifications).
b. Fit the pre-load shims in the case and install
the carrier bearing race using a brass drift.
c. Lubricate both planetary carrier bearings
with gear oil and install the carrier assembly
in the final drive case using a new gasket.
Torque tighten the bolts (see torque
specifications).
d.
Clean the contact face of the final drive
case and ensure that the thrust washer has
been removed from the top of the planetary
carrier shaft.
e. Position the special measuring tool
J 28867/3 (part of the A/T Tool Kit) on the
final drive case.
Use a depth gauge to measure the distance from
the top face of the special tool to the top of the
planetary carrier shaft (with thrust washer
removed). Fig. 73
f. Subtract the measurement from 120 mm
(4.724 in.) to obtain dimension "A". Fig. 73
13.
Perform the planetary gear carrier bearing
pre-
load adjustment as follows:
a. Install the planetary carrier and gasket in
the final drive case. Torque tighten the
bolts (see torque specifications).
b. Wrap a piece of string around the planetary
gear carrier and pull with a spring scale to
measure the bearing pre-load.

Take the measurement while the carrier is rotating.
The bearing pre-load should be:
New Bearings:
5—12
Nm (1 -3
lb. ft.).
Used Bearings: Turn free without play.

CASE MEASUREMENT
Fig. 74 BEARING PRE-LOAD ADJUSTMENT
Notice:
Perform steps "c" and "d" if the bearing pre-load
is NOT WITHIN specification:
c. Remove the planetary gear carrier from the
case.
d.
Remove the planetary gear carrier bearing
outer race from the final drive case and
adjust the thickness of the shim pack to
obtain the proper bearing pre-load. Re-
install planetary gear carrier and check
adjustment.
e. After pre-load is checked and adjusted,
remove the planetary gear carrier, separate
the final drive case, and reassemble the
final drive (see FINAL DRIVE RE-
ASSEMBLY section for procedures).
