Pinion Seal - Installation
INSTALLATION
1. Apply a light coating of gear lubricant on the lip of pinion seal.
2. Install new pinion seal with Seal Installer C-3972-A (1) and Driver Handle C-4171 (2).
3. Position flange on pinion shaft with the reference marks aligned.
4. Install flange on pinion shaft with Flange Installer C-3718 and Flange Holder C-3281.
5. Install pinion washer and a new pinion nut. The convex side of the washer must face outward.
6. Hold flange with Flange Holder C-3281 and tighten pinion nut to 285 Nm (210 ft. lbs.). Rotate pinion several revolutions to ensure bearing rollers
are seated. NOTE: Do not exceed the minimum tightening torque 285 Nm (210 ft. lbs.) when installing the companion flange retaining nut
at this point.
7. Rotate pinion several times to ensure bearings are seated.
8. 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.
9. Install propeller shaft.
10. Install rear brake components.
