(2) Install new pinion seal with an aproppriate
installer (Fig. 23).
Fig. 23 Pinion Seal Installation
1 - SPECIAL TOOL C—4171
2 - SPECIAL TOOL C—8108
NOTE: The seal is correctly installed when the seal
flange contacts the face of the differential housing
flange.
(3) Position the pinion yoke on the end of the shaft
with the reference marks aligned.
(4) Seat yoke on pinion shaft with Installer C-3718
and Yoke Holder 6719.
(5) Remove the tools and install the pinion yoke
washer and nut.
CAUTION: Do not exceed the minimum tightening
torque when installing the pinion yoke retaining nut
at this point. Damage to collapsible spacer, if
equipped, or bearings may result.
(6) Hold pinion yoke with Yoke Holder 6719 and
tighten shaft nut to 291.5 N·m (215 ft. lbs.) (Fig. 24).
Rotate pinion shaft several revolutions to ensure the
bearing rollers are seated.

(7) Rotate the pinion shaft using a (in. lbs.) torque
wrench. Rotating resistance torque should be equal
to the reading recorded during removal, plus an addi-
tional 0.56 N·m (5 in. lbs.) (Fig. 25).
CAUTION: Never loosen pinion gear nut to decrease
pinion gear bearing rotating torque and never
exceed specified preload torque. If preload torque
is exceeded a new pinion nut and collapsible
spacer, if equipped, must be installed. The torque
sequence will then have to be repeated.
(8) If the rotating torque is low, use Yoke Holder
6719 to hold the pinion yoke (Fig. 24) and tighten the
pinion shaft nut in 6.8 N·m (5 ft. lbs.) increments
until proper rotating torque is achieved.
NOTE: The bearing rotating torque should be con-
stant during a complete revolution of the pinion. If
the rotating torque varies, this indicates a binding
condition.
(9) Install the propeller shaft with the installation
reference marks aligned.
(10) Tighten the universal joint yoke clamp screws
to 19 N·m (14 ft. lbs.).
