Differential Pinion Shaft, Differential Pinion and Differential Side
Gear
1. Take out the differential side gear (3) and shim (2).
2. Tap out the dowel pin (6).
3. Pull out the differential pinion shaft (7), then take out the
differential pinions (5), thrust collars (4), differential side gear
(10) and shim (9).
A Arrange the parts to know their original positions.
(When reassembling)
A Apply molybdenum disulfide (Three Bond 1901 or equivalent)
to the inner circumferential surface of the differential side
gears (3), (10) and differential pinions (5).
A Apply grease to the outer surface of the pinion thrust collars (4)

Checking Bearing
1. Hold the inner race, and push and pull the outer race in all
directions to check for wear and roughness.
2. Apply transmission fluid to the bearing, and hold the inner
race. Then, turn the outer race to check rotation.
3. If there is any defect, replace it.
Clutch Disc Wear
1. Measure the clutch disc thickness with vernier calipers.
2. If the thickness is less than the allowable limit, replace it.
