Shift Fork Clearance Inspection
Shift Fork Clearance InspectionNOTE: 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 inch)
Service Limit: 1.0 mm (0.039 inch)
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.
- If one arm of the shift fork shows more wear than others, the fork may be bent and needs to be replaced.
Standard: 7.47.6 mm (0.29 - 0.30 inch)
3. Measure the clearance between the shift fork (A) and the shift arm (B). If the clearance exceeds the service limit, go to step 4.
Standard: 0.2 - 0.5 mm (0.008 - 0.020 inch)
Service Limit: 0.62 mm (0.024 inch)
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 shift piece.
Standard: 16.9 - 17.0 mm (0.665 - 0.669 inch)
