(9) Torque output shaft retaining nut to 271 N´m
(200 ft. lbs.) (Fig. 260).
(10) Set up Tool L-4432 and C-4658 as shown in
(Fig. 261). Install dial indicator and measure output
shaft end play.(11) Using an in. lb. torque wrench, measure out-
put shaft bearing turning torque (Fig. 262).
(12) Install stirrup and strap. Install bolts but do
not tighten.
NOTE: Once the stirrup assembly is positioned
onto the output gear, it is necessary to ªclockº the
stirrup against the flats of the output gear retaining
nut.
(13) Rotate stirrup clockwise against flats of gear
retaining nut (Fig. 263).

(14) Torque stirrup and strap bolts to 23 N´m (200
in. lbs..) (Fig. 264).
(15) Bend tabs of strap up against ªflatsºof retain-
ing bolts to prevent bolts from backing out of gear in
the event they come loose.
(16) Install transfer shaft and gear. (Refer to 21 -

ADJUSTMENTS
ADJUSTMENT - OUTPUT SHAFT BEARING
(1) With output shaft gear removed, install a 13.65
mm (0.537 inch) and a 1.34 mm (0.053 inch) gauging
shims on the planetary rear annulus gear hub usinggrease 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´m (200 ft. lbs.).
(3) To measure bearing end play:
(4) Attach Tool L-4432 to the output shaft gear.
(5) Mount a steel ball with grease into the end of
the output shaft.
(6) Push and pull the gear while rotating back and
forth to insure seating of the bearing rollers.
(7) Using a dial indicator, mounted to the trans-
axle case, measure output shaft end play.
(8) Once bearing end play has been determined,
refer to the output shaft bearing shim chart.
(9) The 12.65 mm (0.498 inch), 13.15 mm (0.518
inch) or 13.65 mm (0.537 inch) shims are always
installed first.These shims have lubrication slots
which are necessary for proper bearing lubrica-
tion.
(10) Shims thinner than 12.65 mm listed in the
chart are common to both the transfer shaft and out-
put shaft bearings.
(11) Use Tool L-4434 to remove the retaining nut
and washer. To remove the output shaft gear use Tool
L-4407.
(12) Remove the two gauging shims and install the
proper shim combination, making sure to install the
12.65, 13.15, or 13.65 mm shim first. Use grease to
hold the shims in place. Install the output shaft gear
and bearing assembly.
(13) Install the retaining nut and washer and
torque to 271 N´m (200 ft. lbs.).
(14) Using an inch-pound torque wrench, check the
turning torque.The torque should be between 3
and 8 inch-pounds.
(15) If the turning torque is too high, install a
0.05mm (0.002 inch) thicker shim. If the turning
torque is too low, install a 0.05 mm (0.002 inch) thin-
ner shim. Repeat until the proper turning torque is 3
to 8 inch pounds.
