NOTE: The outer perimeter of the seal is pre-coated
with a special sealant. An additional application of
sealant is not required.
(4) Apply a light coating of gear lubricant on the
lip of pinion seal.
(5) Install seal with Installer C-3972-A and Handle
C–4171 (Fig. 8).

(6) Install socket head bolts into two of the
threaded holes in the companion flange, 180° apart.
(7) Position Holder 6719 against the companion
flange and install a hex head bolt and washer into
one of the remaining threaded holes. Tighten the bolt
and washer so that the Holder 6719 is held to the
flange.
(8) Seat the companion flange on the pinion shaft
with Installer C-3718 and Holder 6719.
(9) Remove the Installer C-3718 and install the
new pinion nut.
CAUTION: Do not exceed the minimum tightening
torque when installing the companion flange at this
point. Damage to the collapsible spacer or bearings
may result.
(10) Tighten the pinion nut until there is zero
bearing end-play (Fig. 9).
(11) Tighten the nut to 271 N·m (200 ft. lbs.).
CAUTION: Never loosen pinion nut to decrease pin-
ion bearing rotating torque and never exceed spec-
ified preload torque. If preload torque or rotating
torque is exceeded a new collapsible spacer must
be installed. The torque sequence will then have to
be repeated.
(12) Rotate the pinion shaft using a (in. lbs.)
torque wrench. Rotating torque should be equal to
the reading recorded during removal plus an addi-
tional 0.56 N·m (5 in. lbs.) (Fig. 10).
(13) If the rotating torque is low, use Holder 6719
to hold the companion flange, and tighten the pinion
nut in 6.8 N·m (5 ft. lbs.) increments until the proper
rotating torque is achieved.
