DETERMINING SHIM THICKNESS
Shim thickness need only be determined if any of
the following parts are replaced:
• Transaxle case
• Differential carrier
• Differential bearing retainer
• Extension housing
• Differential bearing cups and cones
Refer to Bearing Adjustment Procedure in rear
of this section to determine proper shim thickness for
correct bearing preload and proper bearing turning
torque.
When rebuilding, reverse the above procedure.

to seal retainer to case.
BEARING ADJUSTMENT PROCEDURES
GENERAL RULES ON SERVICING BEARINGS
(1) Take extreme care when removing and in stalling
bearing cups and cones. Use only an arbor press for
installation, as a hammer may not properly align the
bearing cup or cone. Burrs or nicks on the bearing seat
will give a false end play reading, while gauging for
proper shims. Improperly seated bearing cup and cones
are subject to low-mileage failure.
(2) Bearing cups and cones should be replaced if they
show signs of pitting or heat distress.
If distress is seen on either the cup or bearing rollers,
both cup and cone must be replaced.
Bearing end play and drag torque specifica-
tions must be maintained to avoid premature
bearing failures.
Used (original) bearing may lose up to 50 of the
original drag torque after break-in.
All bearing adjustments must be made with no
other component interference or gear inter-
mesh, except the transfer gear bearing.
OUTPUT SHAFT BEARING
With output shaft gear removed.
(1) Install a 13.65 mm (.537 inch) and a 1.34 mm
(.053 inch) gauging shims on the planetary rear annu-
lus gear hub using grease to hold the shims in place.
The 13.65 mm shim has a larger inside diameter and
must be installed over the output shaft first. The 1.34
mm shim pilots on the output shaft.
(2) Install output shaft gear and bearing assembly,
torque to 271 N
Im (200 ft. lbs.).
(3) To measure bearing end play:
(a) Attach Tool L-4432 to the output shaft gear.
(b) Mount a steel ball with grease into the end of
the output shaft.
(c) Push and pull the gear while rotating back and
forth to insure seating of the bearing rollers.
(d) Using a dial indicator, mounted to the tran-
saxle case, measure output shaft end play.
(4) Once bearing end play has been determined,
refer to the output shaft bearing shim chart for the
required shim combination to obtain proper bearing
setting.
(a) The 12.65 mm (.498 inch), 13.15 mm (.518 inch)
or 13.65 mm (.537 inch) shims are always in-
