Standard clearance:
15.2 to 15.4 mm (0.598 to 0.606 in.)
Maximum clearance:
15.4 mm (0.606 in.)
HINT
If the clearance exceeds the maximum, replace the No. 4 gear shift fork with a new one.
7. INSPECT REVERSE AND 5TH SHIFT HEAD
(a) Using a vernier caliper, measure the clearance of the reverse and 5th shift head groove.
Standard clearance:
15.2 to 15.4 mm (0.598 to 0.606 in.)
Maximum clearance:
15.4 mm (0.606 in.)
HINT
If the clearance exceeds the maximum, replace the reverse and 5th shift head with a new one.
8. INSPECT NO. 4 SYNCHRONIZER RING
(a) Apply manual transmission gear oil to the taper cone of the counter 6th gear, and then hold the No. 4 synchronizer ring in position with your hand to measure the clearance between the No. 4 synchronizer ring and counter 6th gear by using a feeler gauge.
Standard clearance:
0.88 to 1.52 mm (0.0346 to 0.0598 in.)
Minimum clearance:
0.88 mm (0.0346 in.)
NOTICE:
Check the entire circumference of the gear.
HINT
If the clearance is less than the minimum, replace the No. 4 synchronizer ring and counter 6th gear with a new one.
(b) Apply manual transmission gear oil to the taper cone of the counter 6th gear, and then hold the No. 4 synchronizer ring in position with your hand to check that it does not slide in the circumferential direction.
HINT
If the No. 4 synchronizer ring slides, replace the No. 4 synchronizer ring and counter 6th gear with a new one.
9. INSPECT COUNTER 6TH GEAR
(a) Using a cylinder gauge, measure the inside diameter of the counter 6th gear.
Standard inside diameter:
34.015 to 34.040 mm (1.33917 to 1.34016 in.)
Maximum inside diameter:
34.040 mm (1.34016 in.)
HINT
If the inside diameter exceeds the maximum, replace the counter 6th gear with a new one.
10. INSPECT NO. 4 TRANSMISSION HUB SLEEVE
(a) Check that the spline gear edges of the No. 4 transmission hub sleeve are not worn down.
HINT
If it shows any sign of wear, replace the No. 4 transmission hub sleeve with a new one.
(b) Install the No. 4 transmission hub sleeve to the No. 4 transmission clutch hub, and then check that it slides smoothly.
HINT
If it does not slide smoothly, replace the No. 4 transmission hub sleeve and No. 4 transmission clutch hub with a new one.
11. INSPECT NO. 4 TRANSMISSION HUB SLEEVE CLEARANCE
(a) Using a vernier caliper, measure the claw width of the No. 4 gear shift fork.
Standard width:
7.9 to 8.0 mm (0.311 to 0.315 in.)
Minimum width:
7.9 mm (0.311 in.)
HINT
If the width is less than the minimum, replace the gear No. 4 shift fork with a new one.
(b) Using a vernier caliper, measure the groove of the No. 4 transmission hub sleeve and then calculate the clearance with the No. 4 gear shift fork.
Standard clearance:
0.15 to 0.35 mm (0.00590 to 0.0138 in.)
Maximum clearance:
0.35 mm (0.0138 in.)
HINT
If the clearance exceeds the maximum, replace both the No. 4 gear shift fork and No. 4 transmission hub sleeve with a new ones.
12. INSPECT REVERSE IDLER GEAR SUB-ASSEMBLY
(a) Using a cylinder gauge, measure the inner diameter of the reverse idler gear sub-assembly.

22.040 to 22.061mm (0.86771 to 0.86854 in.)
Maximum inside diameter:
22.061mm (0.86854 in.)
HINT
If the inside diameter exceeds the maximum, replace the reverse idler gear sub-assembly with a new one.
13. INSPECT REVERSE IDLER GEAR SHAFT
(a) Using a micrometer, measure the outer diameter of the reverse idler gear shaft.
Standard outer diameter:
21.979 to 22.000 mm (0.86531 to 0.86614 in.)
Minimum outer diameter:
21.979 mm (0.86531 in.)
HINT
If the outer diameter is less than the minimum, replace the reverse idler gear shaft with a new one.
