(3) Disassembling Differential Gear
Spiral Bevel Gear
1. Remove the external circlip (6) and the 21T spiral bevel gear (5)
with bearing (4).
2. Remove the bearing (1).
3. Remove the differential case cover mounting screws and
remove the differential case cover.
4. Tap out the roll pin (14) and draw out the differential pinion shaft
(13) and pinion gears (10), differential side gear (11) and shim.
(When reassembling)
• Replace the external circlip (6) with new one.
• Check the differential pinion gears (10), pinion shaft (13) for
excessive wear. If these parts are damaged or excessively
worn, replace the parts they mesh with, or are sliding on.
• Apply molybdenum disulfide (Three Bond 1901 or equivalent) to
inner circumferential surface of differential pinions, side gear
and shim.
• Install the parts to there original position.
• Face the roll pin (14) as shown in the photo.
