INSTALLATION
1. Apply a light coating of gear lubricant on the lip of
pinion seal. Install seal with Installer 8681(2).
2. Install pinion companion flange on the pinion gear
with Installer W-162-D, Cup 8109 and Wrench
6958.
CAUTION: Do not exceed the minimum tightening
torque 217 N·m (160 ft. lbs.) while installing pinion
nut at this point. Failure to follow these instruc-
tions will result in damage.
3. Install a new nut on the pinion gear. Tighten the
nut only enough to remove the shaft end play.
CAUTION: Never loosen pinion nut to decrease
pinion rotating torque and never exceed specified
preload torque. Failure to follow these instructions
will result in damage.
4. Rotate pinion a minimum of ten time and verify pin-
ion rotates smoothly. Rotate the pinion shaft (1) with an inch pound torque wrench (2). Rotating torque should be
equal to the reading recorded during removal plus 0.56 N·m (5 in. lbs.).
5. If rotating torque is low, use Spanner Wrench 6958 to hold the pinion companion flange and tighten the pinion
nut in 6.8 N·m (5 ft. lbs.) increments until proper rotating torque is achieved.
CAUTION: If maximum tightening torque is reached prior to reaching the required rotating torque, the col-
lapsible spacer may have been damaged. Failure to follow these instructions will result in damage.
6. Install propeller shaft.
7. Fill differential with gear lubricant.
