(10) Use a suitable pry tool or slide hammer
mounted screw to remove the pinion gear seal.
INSTALLATION
(1) Apply a light coating of gear lubricant on the
lip of pinion seal. Install seal with Installer C-3972-A
and Handle C-4171 (Fig. 8).
(2) Install yoke on the pinion gear with Screw
8112, Cup 8109, and Holder 6958 (Fig. 9).
CAUTION: Do not exceed the minimum tightening
torque when installing the pinion yoke at this point.
Damage to the collapsible spacer or bearings may
result.
(3) Install the yoke washer and a new nut on the
pinion gear and tighten the pinion nut until there is
zero bearing end-play.
(4) Tighten the nut to 271 N·m (200 ft. lbs.).
CAUTION: Never
loosen
pinion
gear
nut
to
decrease pinion gear bearing rotating torque and
never exceed specified preload torque. If preload
torque or rotating torque is exceeded a new col-
lapsible spacer must be installed. The torque
sequence will then have to be repeated.
(5) Rotate the pinion shaft using a (in. lbs.) torque
wrench. Rotating torque should be equal to the read-
ing recorded during removal plus an additional 0.56
N·m (5 in. lbs.) (Fig. 10).
(6) If the rotating torque is low, use Holder 6958 to
hold the pinion yoke (Fig. 11), and tighten the pinion
shaft nut in 6.8 N·m (5 ft. lbs.) increments until the
proper rotating torque is achieved.
CAUTION: If the maximum tightening torque is
reached prior to reaching the required rotating
torque, the collapsible spacer may have been dam-
aged. Replace the collapsible spacer.
(7) Align the installation reference marks on the
propeller shaft and yoke and install the propeller
shaft.
(8) Add gear lubricant to the differential housing,
if necessary. Refer to the Lubricant Specifications for
gear lubricant requirements.
(9) Install the brake drums. Refer to Group 5,
Brakes, for proper procedures.
(10) Install wheel and tire assemblies.
