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.
(b) Using a press, remove the center bearing, 1st gear,
needle roller bearing, inner race and synchronizer ring.
4. REMOVE LOCKING BALL ON OUTPUT SHAFT

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
gear cone. Check that the ring locks.
If it does not lock, replace the synchronizer ring.

(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.)
If the outer diameter is less than the minimum, replace the out-
put shaft.

(d) Using a micrometer, measure the outer diameter of the in-
ner race.
Minimum diameter: 42.975 mm (1.6919 in.)
If the outer diameter is less than the minimum, replace the inner
race.
(e) Using a dial indicator, check the shaft runout.
Maximum runout: 0.06 mm (0.0024 in.)
If the runout exceeds the maximum, replace the output shaft.

INSPECTION
1. INSPECT COUNTER 5TH GEAR RADIAL CLEAR-
ANCE
(a) Install the spacer, counter 5th gear and needle roller bear-
ing to the counter gear.
(b) Using a dial indicator, measure the counter 5th gear radial
clearance.
Standard clearance:
0.009 − 0.060 mm (0.0004 − 0.0024 in.)
Maximum clearance:
0.150 mm (0.0059 in.)
If the clearance exceeds the maximum, replace the counter
gear, needle roller bearing or counter 5th gear.
2. INSPECT COUNTER GEAR
Using a micrometer, measure the outer diameter of the counter
shaft journal.
Minimum diameter:
Part A: 26.975 mm (1.0620 in.)
Part B: 29.950 mm (1.1791 in.)
If the outer race is less than the minimum, replace the counter
gear.
3. INSPECT REVERSE IDLER GEAR RADIAL CLEAR-
ANCE
Using a dial indicator, measure the reverse idler gear radial
clearance.
Standard clearance:
0.041 − 0.074 mm (0.0016 − 0.0029 in.)
Maximum clearance:
0.194 mm (0.0076 in.)
If the clearance exceeds the maximum, replace the gear or
shaft.
4. INSPECT REVERSE IDLER GEAR AND SHIFT ARM
SHOE CLEARANCE
Using a feeler gauge, measure the clearance between the re-
verse idler gear and shift arm shoe.
Standard clearance:
0.20 − 0.41 mm (0.0079 − 0.0161 in.)
Maximum clearance:
0.90 mm (0.0354 in.)
If the clearance exceeds the maximum, replace the shift arm
shoe or reverse idler gear.
