15. INSPECT SYNCHRONIZER RING NO.2 (FOR FOURTH
SYNCHRONIZER RING)
(a) Coat the 4th gear cone with gear oil. Check the braking
effect of the synchronizer ring No.2. Turn the synchroniz-
er ring No.2 in one direction while pushing it to the 4th
gear cone. Check that the ring locks.
If the braking effect is insufficient, apply a small amount of the
fine lapping compound between the synchronizer ring No.2 and
4th gear cone. Lightly rub the synchronizer ring No.2 and 4th
gear cone together.
NOTICE:
Ensure the fine lapping compound is completely washed
off after rubbing.
(b) Check again the braking effect of the synchronizer ring
No.2.
(c) Using a feeler gauge, measure the clearance between
the synchronizer ring No.2 back and 4th gear spline end.
Standard clearance:
0.75 ± 1.65 mm (0.0295 ± 0.0649 in.)
If the clearance is less than the minimum, replace the synchro-
nizer ring and apply a small amount of the fine lapping com-
pound on 4th gear cone.
NOTICE:
Ensure the fine lapping compound is completely washed
off after rubbing.
16. INSPECT SYNCHRONIZER RING NO.2 (FOR THIRD
SYNCHRONIZER RING)
(a) Coat the 3rd gear cone with gear oil. Check the braking
effect of the synchronizer ring No.2. Turn the synchroniz-
er ring No.2 in one direction while pushing it to the 3rd
gear cone. Check that the ring locks.
If the braking effect is insufficient, apply a small amount of the
fine lapping compound between the synchronizer ring No.2 and
3rd gear cone. Lightly rub the synchronizer ring No.2 and 3rd
gear cone together.
NOTICE:
Ensure the fine lapping compound is completely washed
off after rubbing.
(b) Check again the braking effect of the synchronizer ring
No.2.

compound on the 3rd gear cone.
NOTICE:
Ensure the fine lapping compound is completely washed
off after rubbing.
17. INSPECT TRANSMISSION HUB SLEEVE NO.2
(a) Check the sliding condition between the transmission hub
sleeve No.2 and transmission clutch hub No.2.
(b) Check that the spline gear's edges of the transmission
hub sleeve No.2 is not worn down.
(c) Using a vernier calipers, inspect the transmission hub
sleeve No.2 and gear shift fork No.2 as shown in the il-
lustration.
Standard clearance:
0.15 ± 0.35 mm (0.0059 ± 0.0137 in.)
If the clearance exceeds the standard clearance, replace the
transmission hub sleeve No.2 and gear shift fork No.2.
18. INSTALL TRANSMISSION HUB SLEEVE NO.2
(a) Coat the transmission hub sleeve No.2 with gear oil,
install it to the transmission clutch hub No.2.
NOTICE:
Do not set the transmission hub sleeve No.2 and the trans-
mission clutch hub in incorrect orientation.
(b) Install the 2 synchromesh key springs with 3 synchro-
mesh shifting keys No.2 to the transmission clutch hub
No.2.
