bearing end-play. It will not be possible at this point
to achieve zero bearing end-play if a new collapsible
spacer was installed.
(13) Tighten the nut to 285 N·m (210 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.
(14) Using Yoke Holder 6719, crush collapsible
spacer until bearing end play is taken up.
(15) Slowly tighten the nut in 6.8 N·m (5 ft. lbs.)
increments until the desired rotating torque is
achieved. Measure the rotating torque frequently to
avoid over crushing the collapsible spacer (Fig. 35).
(16) Check bearing rotating torque with an inch
pound torque wrench (Fig. 35). The torque necessary
to rotate the pinion gear should be:
•
Original Bearings — 1 to 2 N·m (10 to 20 in. lbs.).
•
New Bearings — 1 to 5 N·m (10 to 30 in. lbs.).
(17) Install propeller shaft.
(18) Install differential in housing.
