Differential Gear Assembly Removal

1. Remove the Differential Side Gears, Thrust Washers, Dif-
ferential Pinion Gears, and the Differential Pinion Shaft
from the Final Gear. (Fig. 17)
2. Inspect the Side and Pinion Gears and Pinion Shaft for
scoring, pitting, discoloration and chipped or broken
teeth.

Differential Pinion Shaft and Gears Tolerance
1. Using calipers (digital recommended) measure the O. D.
(X) of the Pinion Shaft. (Fig. 18)

Axle Seal Removal

1. After the Differential Gear Assembly and Axles have
been removed, take out the (2) Axle Seals at each end of
the Upper Case. (Fig. 19)
Fig. 19, Axle Seal Removal
Extreme caution should be taken when remov-
ing Seals from the Upper Case. Immediately behind
each Axle Seal is a press-fit bushing. If damaged, the
Upper Case must be replaced, bushings can not be
replaced separately.
Seals should be replaced every time the Axles
are removed.
2. Measure the I. D. (Y) of the Pinion Gears. (Fig. 18)
If the clearance (Y-X) is > 0.50 mm (0.019 in), replace the
3.
Pinion Shaft and/or Pinion Gears.
◆ Example of an Unacceptable Tolerance:
Pinion Shaft O. D. (X) = 14.75 mm
Pinion Gear I. D. (Y) = 15.30 mm
Y (15.30 mm) - X (14.75 mm) = 0.55 mm of
clearance. This is
replacement is necessary.
