Shift Fork Clearance Inspection

NOTE: If replacement is required, always replace the synchro sleeve and hub 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: 1.00 mm (0.039 in.)

  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 hub.
    • If one arm of the shift fork shows more wear than the others, the fork may be bent and needs to be replaced.

    Standard: 

    1-2 Shift Fork: 7.4-7.6 mm (0.29-0.30 in.) 

    3-4,5-6, Reverse Shift Fork: 6.2-6.4 mm (0.24-0.25 in.)

  3. Measure the clearance between each shift fork, reverse shift piece, and shift arm A. 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.)

  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.

    Standard: 16.8-17.0 mm (0.661-0.669 in.) 

    Service Limit: 16.7 mm (0.657 in.)

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

    Standard: 0-0.4 mm (0-0.016 in.) 

    Service Limit: 0.5 mm (0.020 in.)

  6. Measure the width of the 1-2 shift lever.
    • If the width is less than the service limit, replace the 1-2 shift lever.
    • If the width is within the service limit, replace the shift fork or shift piece.

    Standard: 17.0-17.2 mm (0.669-0.677 in.) 

    Service Limit: 16.9 mm (0.665 in.)
