Standard:
Minimum:
If the diameter is less than the minimum, replace the counter gear shaft.
8. INSPECT COUNTER SHAFT REVERSE GEAR
(a) Using a cylinder gauge, measure the inside diameter of the reverse gear.

51.015 to 51.040 mm (2.00846 to 2.00944 in.)
Maximum inside diameter:
51.040 mm (2.00944 in.)
If the inside diameter exceeds the maximum, replace the reverse gear.
9. INSPECT COUNTER SHAFT GEAR 1ST SPEED
(a) Using a cylinder gauge, measure the inside diameter of the 1st gear.
Standard inside diameter:
54.015 to 54.040 mm (2.12657 to 2.12755 in.)
Maximum inside diameter:
54.040 mm (2.12755 in.)
If the inside diameter exceeds the maximum, replace the 1st gear.
10. INSPECT COUNTER SHAFT 2ND SPEED GEAR
(a) Using a cylinder gauge, measure the inside diameter of the 2nd gear.
Standard inside diameter:
60.015 to 60.040 mm (2.36279 to 2.36377 in.)
Maximum inside diameter:
60.040 mm (2.36377 in.)
If the inside diameter exceeds the maximum, replace the 2nd gear.
11. INSPECT NO. 3 TRANSMISSION HUB SLEEVE
(a) Using a vernier caliper, measure the width of the No. 3 transmission hub sleeve groove (A) and the thickness of the claw part on the No. 4 gear shift fork (B), and calculate the clearance.
Standard clearance (A - B):
0.26 to 0.84 mm (0.0102 to 0.0331 in.)
If the clearance is outside the specification, replace the No. 3 transmission hub sleeve and No. 4 gear shift fork.
12. INSPECT NO. 1 TRANSMISSION HUB SLEEVE
(a) Check the sliding condition between the No. 1 transmission clutch hub and No. 1 transmission hub sleeve.
(b) Check that the spline gear teeth of the No. 1 transmission hub sleeve are not worn.
(c) Using a vernier caliper, measure the width of the No. 1 transmission hub sleeve groove (A) and the thickness of the claw part on the No. 1 gear shift fork (B), and calculate the clearance.
Standard clearance (A - B):
0.15 to 0.35 mm (0.00590 to 0.0138 in.)
If the clearance is outside the specification, replace the No. 1 transmission hub sleeve and No. 1 gear shift fork.
13. INSPECT NO. 4 SYNCHRONIZER RING
(a) Using a feeler gauge, measure the clearance between the synchronizer ring and reverse gear.

Minimum clearance:
0.70 mm (0.0276 in.)
If the clearance is less than the minimum, replace the synchronizer ring.
(b) Coat the reverse gear cone with gear oil. Check the braking effect of the synchronizer ring. Turn the synchronizer ring in one direction while pushing it onto the reverse gear cone. Check that the ring locks.
14. INSPECT NO. 1 SYNCHRONIZER RING SET (for 1st Gear)
(a) Using a feeler gauge, measure the clearance between the synchronizer ring and 1st gear.
