Installation

INSTALLATION




1. Apply a light coating of gear lubricant on the lip of pinion seal.
2. Install new pinion seal with Installer C-4076-B (1) and Handle C-4735 (2).




3. Install flange on the pinion shaft with the reference marks aligned.
4. Install flange (1) with Installer C-3718 (2).




5. Install new pinion nut. Hold flange (1) with Holder C-3281 (2) and tighten pinion nut to 285 Nm (210 ft. lbs.). Rotate pinion several revolutions to ensure the bearing rollers are seated.

NOTE: Do not exceed the minimum torque 285 Nm (210 ft. lbs.) when installing the pinion nut at this point.




6. Measure pinion torque to rotate (1) with an inch pound torque wrench (2). Pinion torque to rotating should be equal to recorded reading plus an additional 0.56 Nm (5 in. lbs.).

If pinion torque to rotate is low, tighten pinion nut in 6.8 Nm (5 ft. lbs.) increments until pinion torque to rotating is achieved.


CAUTION: Never loosen pinion nut to decrease pinion bearing rotating torque. If pinion torque to rotating is exceeded, a new collapsible spacer must be installed. Failure to follow these instructions will result in damage to the axle.




7. Install propeller shaft (1) with axle flange (2) installation reference marks aligned.
8. Install rear brake components.
