Oil Seal-Pinion
Remove1. Release both drive shafts from differential assembly.
2. Reference mark propeller shaft and pinion flanges to aid reassembly.
3. Remove 4 nuts and bolts securing propeller shaft to differential. Release propeller shaft and tie aside.
4. Check and record the torque required to rotate the pinion and differential.
CAUTION: Drive shafts must be removed to obtain correct torque to turn figure.
5. Using LRT-51-003 to restrain differential flange, remove nut and washer securing pinion flange. Discard nut.
6. Remove pinion flange.
7. Carefully remove and discard oil seal, take care not to damage oil seal recess.
8. Remove oil thrower.
9. Remove pinion bearing inner race.
10. Remove and discard collapsible spacer.
Refit
1. Fit new collapsible spacer.
2. Fit pinion bearing and oil thrower.
3. Clean pinion flange and oil seal recess.
4. Fit new oil seal using LRT-51-010.
5. Fit pinion flange and washer.
6. Restrain pinion flange using LRT-51-003.
7. Fit new pinion nut and tighten to 190 Nm (140 ft. lbs.)
8. Check for end float on pinion. If end float exists continue to tighten pinion nut until end float is removed.
9. Continue to tighten pinion nut until correct preload is obtained.
10. Pinion preload is 1.7 - 2.8 Nm (1.2 - 2.1 ft. lbs.), if higher replace collapsible spacer.
CAUTION: Do not tighten pinion nut to more than 373 Nm (275 ft. lbs.), or the collapsible spacer will compress too far.
11. Clean propeller shaft flange and mating face.
12. Position propeller shaft to rear axle and align reference marks.
13. Tighten propeller shaft nuts and bolts to 65 Nm (48 ft. lbs.).
14. Fit drive shafts.
15. Check differential oil level.
