Shift Fork Clearance Inspection

WARNING: This page is about a different variant/trim than selected.

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 (0.0138-0.0256 in)

Service Limit: 1.0 mm (0.039 in)

Measure the thickness of the shift fork (A) 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.
  Standard:
  
  1st/2nd shift fork: 6.7-6.9 mm (0.264-0.272 in)
  
  3rd/4th, 5th/6th shift forks: 7.4-7.6 mm (0.291-0.299 in)

Service Limit: 0.6 mm (0.024 in)

Measure the width of the shift piece (A).
- If the width is not within the standard, replace the shift piece.
- If the width is within the standard, replace the shift fork or the reverse shift piece.
