Using a vernier caliper, measure the width of the No. 3 transmission hub sleeve groove (A) and the thickness of the claw part of the gear shift fork No. 4 (B), and calculate the clearance.

Standard clearance (A - B):

0.26 to 0.84 mm (0.0102 to 0.0331 in.)

Check the sliding condition between the No. 1 transmission hub and No. 1 transmission hub sleeve.

Check that the splines of the No. 1 transmission hub sleeve are not worn.

Using a vernier caliper, measure the width of the No. 1 transmission hub sleeve groove (A) and the thickness of the claw part of the No. 1 gear shift fork (B), and calculate the clearance.

Standard clearance (A - B):

0.15 to 0.35 mm (0.00591 to 0.0138 in.)

Using a feeler gauge, measure the clearance between the synchronizer ring and reverse gear.

Standard clearance:

0.70 to 1.50 mm (0.0276 to 0.0590 in.)

0.70 mm (0.0276 in.)

Coat the reverse gear cone with gear oil.

Check the braking effect of the synchronizer ring.

1. Turn the synchronizer ring in both directions while pushing it against the reverse gear cone. Check that the ring locks in both directions.
   

   1. If No. 4 synchronizer ring turns, replace it.
      

Using a feeler gauge, measure the clearance between the synchronizer ring and 1st gear.
