Using a dial indicator, check the input shaft runout.

Maximum runout:

0.015 mm (0.000591 in.)

Using a micrometer, measure the outer diameter of the input shaft journal surface, at the locations indicated.

Standard outer diameter:

Part A:

24.885 to 24.900 mm (0.9797 to 0.9803 in.)

Part B:

28.991 to 29.006 mm (1.1414 to 1.1420 in.)

Part C:

30.985 to 31.000 mm (1.2199 to 1.2205 in.)

Part D:

24.985 to 25.000 mm (0.9837 to 0.9843 in.)

Minimum outer diameter:

Part A:

24.885 mm (0.9797 in.)

Part B:

28.991 mm (1.1414 in.)

Part C:

30.985 mm (1.2199 in.)

Part D:

24.985 mm (0.9837 in.)

Using a cylinder gauge, measure the inside diameter of the 4th gear.

Standard inside diameter:

34.015 to 34.031 mm (1.3392 to 1.3398 in.)

Maximum inside diameter:

34.031 mm (1.3398 in.)

Using a cylinder gauge, measure the inside diameter of the 3rd gear.

Standard inside diameter:

36.015 to 36.031 mm (1.4179 to 1.4185 in.)

Maximum inside diameter:

36.031 mm (1.4185 in.)

Check for wear and damage.

Coat the 4th gear cone with gear oil.

Turn the synchronizer ring in one direction while pushing it against the 4th gear cone.

Check that the ring locks.
If the 4th gear synchronizer outer ring does not lock, replace the synchronizer ring.

Using a feeler gauge, measure the clearance between the synchronizer ring back and the gear spline end.

Standard clearance:

0.75 to 1.65 mm (0.0295 to 0.0650 in.)

Minimum clearance:

0.75 mm (0.0295 in.)

Check for wear and damage.

Coat the 3rd gear cone with gear oil.

Turn the synchronizer ring in one direction while pushing it against the 3rd gear cone.

Check that the ring locks.
If the 3rd gear synchronizer outer ring does not lock, replace the synchronizer ring.

Using a feeler gauge, measure the clearance between the synchronizer ring back and the gear spline end.

Standard clearance:

0.75 to 1.65 mm (0.0295 to 0.0650 in.)

Minimum clearance:

0.75 mm (0.0295 in.)

Check the sliding condition between the No. 2 transmission hub sleeve and the No. 2 transmission clutch hub.

Check that the edges of the No. 2 transmission hub sleeve spline gear are not worn down.

Using a vernier caliper, measure the width of the No. 2 transmission hub sleeve groove (B) and the thickness of the claw part on the No. 2 gear shift fork (A), and calculate the clearance.

Standard clearance (B - A):

0.15 to 0.35 mm (0.00591 to 0.0138 in.)
