the rear differential pinion seal.
a. Removal
1.
2.
Remove parking brake rotor (2) from pinion flange (4).
3.
Using a lb-in. torque wrench, measure torque required to rotate pinion (5) and record
measurement.
4.
Count and record number of exposed threads on end of pinion (5) and mark locknut (3) and
pinion (5) for assembly.
5.
Remove locknut (3) and pinion flange (4) from pinion (5).
6.
Remove pinion seal (6) from pinion (5).
b. Installation

2.
Install pinion flange (4) and locknut (3) on pinion (5).
3.
Tighten locknut (3) to original position.
4.
Tighten locknut (3) in small increments, until torque required to rotate pinion (5) exceeds original
measurement by 2 lb-in. (0.2 Nm).
NOTE
Perform step 5 if replacing front pinion seal.
5.
Connect front propeller shaft (11) to pinion yoke (12) with two straps (9) and four capscrews (10).
Tighten capscrews (10) to 13-18 lb-ft (18-24 Nm).
