INSPECTION
INSPECT SYNCHRONIZER RING
(a) Check for wear or damage.
(b) Check the braking effect of the synchronizer ring.
Turn the synchronizer ring in one direction while pushing
it to the 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 and gear
cone. Lightly rub the synchronizer ring and gear cone together.
NOTICE:
Ensure the fine lapping compound is completely washed
off after rubbing.
(c) Check again the braking effect of the synchronizer ring.
(d) Using a feeler gauge, measure the clearance between
the synchronizer ring back and gear spline end.
Minimum clearance: 0.5 mm (0.020 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 gear cone.
NOTICE:
Ensure the fine lapping compound is completely washed
off after rubbing.

DISASSEMBLY
1. INSPECT EACH GEAR THRUST CLEARANCE
Using a feeler gauge, measure the thrust clearance of each
gear.
Standard clearance:
0.10 − 0.25 mm (0.0039 − 0.0098 in.)
Maximum clearance:
0.30 mm (0.0118 in.)
2. INSPECT EACH GEAR RADIAL CLEARANCE
Using a dial indicator, measure the radial clearance of each
gear.
Standard clearance:
1st and 2nd gears:
0.009 − 0.060 mm (0.0004 − 0.0024 in.)
3rd gear:
0.015 − 0.066 mm (0.0006 − 0.0026 in.)
Maximum clearance:
1st and 2nd gears:
0.150 mm (0.0059 in.)
3rd gear:
0.200 mm (0.0079 in.)
If the clearance exceeds the maximum, replace the gear, shaft
or needle roller bearing.
3. REMOVE OUTPUT SHAFT CENTER BEARING AND
1ST GEAR ASSEMBLY
(a) Shift the No.1 hub sleeve onto the 2nd gear.

INSPECTION
1. INSPECT 1ST GEAR SYNCHRONIZER RING
(a) Check for wear or damage.
(b) Check the braking effect of the synchronizer ring.
Turn the synchronizer ring in one direction while pushing
it to the 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 and gear
cone. Lightly rub the synchronizer ring and gear cone together.
NOTICE:
Ensure the fine lapping compound is completely washed
off after rubbing.
(c) Check again the braking effect of the synchronizer ring.
(d) Using a feeler gauge, measure the clearance between
the synchronizer ring back and gear spline end.
Minimum clearance: 0.5 mm (0.020 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 gear cone.
NOTICE:
Ensure the fine lapping compound is completely washed
off after rubbing.
2. INSPECT 2ND AND 3RD GEAR SYNCHRONIZER
RINGS
(a) Check for wear or damage.
(b) Install the synchronizer inner ring, middle ring and outer
ring to each gear.
(c) Check the braking effect of the synchronizer ring. Turn the
synchronizer ring in one direction while pushing it to the

(d) Using a feeler gauge, measure the clearance between
the synchronizer ring back and the gear spline end.
Minimum clearance: 0.7 mm (0.028 in.)
If the clearance is less than the minimum, replace the synchro-
nizer ring.
3. INSPECT SHIFT FORK AND HUB SLEEVE CLEAR-
ANCE
Using a feeler gauge, measure the clearance between the hub
sleeves and shift forks.
Maximum clearance: 1.0 mm (0.039 in.)
If the clearance exceeds the maximum, replace the shift fork or
hub sleeve.
4. INSPECT OUTPUT SHAFT AND INNER RACE
(a) Using vernier calipers, measure the output shaft flange
thickness.
Minimum thickness: 5.60 mm (0.2205 in.)
If the thickness is less than the minimum, replace the output
shaft.
(b) Using vernier calipers, measure the inner race flange
thickness.
Minimum thickness: 4.78 mm (0.1881 in.)
If the thickness is less than the minimum, replace the inner race.
(c) Using a micrometer, measure the outer diameter of the
output shaft journal.
Minimum diameter:
2nd gear: 42.975 mm (1.6919 in.)
3rd gear: 31.969 mm (1.2586 in.)
