M/T Shift Fork Clearance Inspection

NOTE: The synchro sleeve and synchro hub should be replaced as a set.

1. Measure the clearance between each shift fork (A) and its matching synchro sleeve (B). If the clearance exceeds the service limit, go to Step 2 .

   Standard: | 0.35−0.65 mm (0.014−0.026 in.)
   Service Limit: | 1.0 mm (0.039 in.)

1st/2nd, 3rd/4th, 5th/6th:
Reverse:

1. Measure the thickness of the shift fork fingers.
   - If the thickness is not within the standard, replace the shift fork.
   - If the thickness is within the standard, replace the synchro sleeve.
   - If one arm of the shift fork shows more wear than others, the fork may be bent and needs to be replaced.
   Standard:

   1st/2nd, 3rd/4th, 5th/6th: | 7.4−7.6 mm (0.29−0.30 in.)
   Reverse: | 6.2−6.4 mm (0.24−0.25 in.)

1. Measure the clearance between the shift fork (A) and shift piece (B). If the clearance exceeds the service limit, go to Step 4 .

   Standard: | 0.2−0.6 mm (0.008−0.024 in.)
   Service Limit: | 0.7 mm (0.028 in.)

1. Measure the width of the shift piece.
   - If the width is not within the standard, replace the shift piece.
   - If the width is within the standard, replace the shift fork.

   Standard: | 12.8−13.0 mm (0.50−0.51 in.)
