Check for any wear or damage.

Apply gear oil to the 5th gear cone. Press the No. 3 synchronizer ring against the 5th gear cone and check that the No. 3 synchronizer ring does not turn in the directions shown in the illustration.
If it turns, replace the synchronizer ring.

Using a feeler gauge, check the clearance between No. 3 synchronizer ring and 5th gear with No. 3 synchronizer ring in contact with the cone of the 5th gear.

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. 3 transmission hub sleeve and No. 3 transmission clutch hub.

Check that the edges of the No. 3 transmission hub sleeve spline rear are not worn down.

Using vernier calipers, measure the width of the No. 3 transmission hub sleeve groove (A) and the thickness of the claw part on the No. 3 gear shift fork (B), and calculate the clearance.

Standard clearance (A-B):

0.3 to 0.5 mm (0.012 to 0.020 in.)

Using a caliper gauge, inspect the 5th gear as shown in the illustration.

Standard inside diameter:

29.915 to 29.931 mm (1.1778 to 1.1784 in.)

Maximum inside diameter:

29.931 mm (1.1784 in.)

Using a caliper gauge, inspect the reverse idler gear.

Standard inside diameter:

18.040 to 18.058 mm (0.7102 to 0.7109 in.)

Maximum inside diameter:

18.058 mm (0.7109 in.)

Using a micrometer, inspect the reverse idler gear shaft.

Standard outer diameter:

17.966 to 17.984 mm (0.7073 to 0.7080 in.)

Minimum outer diameter:

17.966 mm (0.7073 in.)
