M/T Shift Forks Clearance Inspection

NOTE: 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 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.
    Standard:
    1st/2nd shift fork:
    6.7−6.9 mm (0.26−0.27 in.)
    3rd/4th, 5th/6th shift fork:
    7.4−7.6 mm (0.29−0.30 in.)


  1. Measure the clearance between the shift fork (A) and the shift piece (B). If the clearance exceeds the service limit, go to Step 4 .
    Standard:
    0.2−0.5 mm (0.008−0.020 in.)


  1. Measure the width of the shift piece.
    • If the width is not within the standard, replace the shift piece.
    • If the width is within the standard, replace the shift fork.
    Standard:
    15.9−16.0 mm (0.626−0.630 in.)
