[3] SERVICING

(1) Differential Gears, Spiral Bevel Pinion, Bevel Gear Case and Bracket

Bi-speed Turn Clutch Assembly
1. Put back the stakes of the nut (1) and remove it.
2. Pull out the ball bearing (2) with a puller and remove the plain
washer (3) shifter collar (4) and shifter (5).
3. Remove the bi-speed turn coupling (6), clutch discs (7), friction
plates (8), and bi-speed turn clutch drum (13).
4. Remove the thrust collar (10), bi-speed turn gear (11) and inner
ring (12) from the bi-speed turn clutch drum (13).
5. Remove the gear shaft (14).
(When reassembling)
• Apply molybdenum desulphid (Three Bond 1901 or equivalent) to
the inner ring.
• Replace the staking nut with a new one and after checking the
turning torque of staking nut (1), be sure to stake it.
• After installing the gear shaft (14) with the bearing, reinstall the
bi-speed turn clutch assembly.
Tightening torque Staking nut
IMPORTANT
• After tightening the staking nut (1) to the specified torque,
be sure to check the turning torque (0.8 to 1.0 N·m, 0.08 to
0.10 kgf·m, 0.59 to 0.73 ft-lbs) of spiral bevel pinion shaft
assembly.

Clearance between Differential Case (Differential Case Cover)
and Differential Side Gear
1. Measure the differential side gear boss O.D..
2. Measure the differential case bore I.D., and calculate the
clearance.
3. Measure the differential case cover bore I.D., and calculate the
clearance.
4. If the clearance exceeds the allowable limit, replace faulty parts.
