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 .
    Standard:
    0.35−0.65 mm (0.014−0.026 in.)
    Service Limit:
    1.0 mm (0.039 in.)

  1. 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 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:
    7.4−7.6 mm (0.29−0.30 in.)

  1. 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 in.)
    Service Limit:
    0.62 mm (0.024 in.)

  1. 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 reverse shift piece.
    Standard:
    16.9−17.0 mm (0.665−0.669 in.)
