8. Install new collapsible spacer (1) on pinion gear
and install pinion in housing.
9. Tap pinion flange onto the pinion.
10. Install flange washer and a new nut on pinion and
tighten pinion nut until there is zero end-play.
11. With a torque wrench and Flange Wrench C-3281
tighten the pinion nut to 285 N·m (210 ft. lbs.).
CAUTION: Never loosen pinion nut to decrease
pinion bearing rotating torque and never exceed
specified preload torque. If preload torque or rotat-
ing torque is exceeded a new collapsible spacer
must be installed. Failure to follow these instruc-
tions will result in damage.
12. Slowly tighten the nut in 6.8 N·m (5 ft. lbs.) incre-
ments
until
the
desired
rotating
torque
is
achieved. Measure rotating torque frequently with
an inch pound torque wrench (2) to avoid over
crushing the collapsible spacer.
13. The pinion rotating torque should be:
•
Original Bearings: 1 to 3 N·m (10 to 20 in. lbs.).
•
New Bearings: 2 to 5 N·m (15 to 35 in. lbs.).
