M/T Reverse Shift Fork Clearance Inspection

  1. Measure the clearance between reverse idler gear (A) and the reverse shift fork (B) with a feeler gauge (C). If the clearance is more than the service limit, go to Step 2 .
    Standard:
    1.30−1.90 mm (0.051−0.075 in.)
    Service Limit:
    2.5 mm (0.098 in.)


  1. Measure the width of the reverse shift fork.
    • If distance is not within the standard, replace the reverse shift fork with a new one.
    • If distance is within the standard, replace the reverse idler gear with a new one.
    Standard:
    13.5−13.8 mm (0.53−0.54 in.)
