M/T Shift Fork Clearance Inspection

M/T Shift Fork Clearance Inspection

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.










2. 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 and the synchro hub as a set.
- If one arm of the shift fork shows more wear than others, the fork may be bent and needs to be replaced.










3. Measure the clearance between each shift fork (A) and the shift arm (B). If the clearance exceeds the service limit, go to step 4.










4. Measure the width of the shift arm.

- If the width is not within the standard, replace the shift arm.
- If the width is within the standard, replace the shift fork or the reverse shift piece.
