Pinion Seal - Installation

INSTALLATION

Special Tools:






CAUTION:
If the pinion seal is being removed or replaced, the pinion bearings, collapsible spacer and pinion flange nut must be replaced.





1. Install new pinion seal (3) with (C-4735) and (C-4076-B) (1).





2. Install flange on the pinion shaft with the reference marks aligned.

3. Install two bolts into the threaded holes in the companion flange, 180° apart.

4. Position (6719A) (2) against the companion flange and install a bolt and washer into one of the remaining threaded holes. Tighten the bolts so holder is held to the flange.

5. Align marks on pinion and companion flange and install on pinion shaft with (C-3718) and (6719A).

6. Install a new pinion nut.

7. Hold companion flange with (6719A) (2) and tighten pinion nut with a torque wrench (3) to 285 Nm (210 ft. lbs.).

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






8. Rotate pinion several times to ensure pinion bearings are seated.

9. Measure pinion torque to rotate (1) with an inch pound torque wrench (2). Pinion torque to rotate 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.

NOTE: Once the proper pinion torque to rotate is achieved, the pinion nut must be staked to the pinion to prevent pinion nut movement.

10. Align marks and install drive shaft. .

11. Install rear brake rotors components.
