M/T Countershaft Assembly Clearance Inspection

  1. Measure the clearance between the 1st gear (A) and the distance collar (B) with a feeler gauge (C). If the clearance is more than the service limit, go to Step 2 .
    Standard:
    0.06−0.16 mm (0.002−0.006 in.)
    Service Limit:
    0.25 mm (0.010 in.)


  1. Measure the thickness of the distance collar.
    • If the thickness is not within than the standard, replace the distance collar.
    • If the thickness is within the standard, go to Step 3 .
    Standard:
    21.53−21.58 mm (0.848−0.850 in.)


  1. Measure the thickness of the 1st gear.
    • If the thickness is less than the standard, replace 1st gear.
    • If the thickness is within the standard, replace the 1st/2nd synchro hub and revers gear as a set.
    Standard:
    21.42−21.47 mm (0.843−0.845 in.)


  1. Measure the clearance between the 2nd gear (A) and 3rd gear (B) with a feeler gauge (C). If the clearance is more than the service limit, go to Step 5 .
    Standard:
    0.06−0.14 mm (0.02−0.006 in.)
    Service Limit:
    0.23 mm (0.009 in.)


  1. Measure the thickness of the distance collar.
    • If the thickness is not within the standard, replace the distance collar.
    • If the thickness is within the standard, go to Step 6 .
    Standard:
    26.53−26.56 mm (1.044−1.046 in.)


  1. Measure the thickness of the 2nd gear.
    • If the thickness is less than the standard, replace 2nd gear.
    • If the thickness is within the standard, replace the 1st/2nd synchro hub and revers gear as a set.
    Standard:
    26.42−26.47 mm (1.040−1.042 in.)
