M/T Shift Fork Clearance Inspection

M/T Shift Fork Clearance Inspection

NOTE: If replacement is required, always replace the synchro sleeve and synchro hub as a set.

1. Measure the clearance between the 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 (A).
- If the thickness is less than 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 the others, the fork may be bent and needs to be relaced.










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










4. Measure the width of shift arm A.
- If the width is less than the service limit, replace shift arm A.

- If the width is within the service limit, replace the shift fork or the reverse shift piece.










5. Measure the clearance between the 1st/2nd shift lever and the each shift fork and shift piece. If the clearance exceeds the service limit, go to step 6.















6. Measure the width of the 1st/2nd shift lever.
- If the width is less than the service limit, replace the 1st/2nd shift lever.

- If the width is within the service limit, replace the shift fork or the shift piece.
