M/T Housing Mainshaft Thrust Clearance Adjustment
  1. Zero a dial gauge (A) on the end of the mainshaft.
  1. Turn the mainshaft holder bolt (B) clockwise; stop turning when the dial gauge (A) has reached its maximum movement. The reading on the dial gauge is the amount of mainshaft thrust clearance.
    NOTE: Do not turn the mainshaft holder bolt more than 60 degrees after the needle of the dial gauge stop moving. Applying more pressure with the mainshaft holder bolt could damage the transmission.
  1. If the reading is with in the standard, the clearance is correct. If the reading is not within the standards, select the appropriate shim needed from the table, and recheck the thrust clearance.
    Standard:
    0.11−0.18 mm (0.004−0.007 in.)

    (Example)
    Measure reading:
    1.93 mm (0.0759 in.)
    Subtract the total clearance measurement from the middle of the clearance standard 0.14 mm (0.0055 in.)

    1.93 − 0.14 = 1.79 mm (0.0705 in.)
    Select the shim closest to the amount calculated, for example the 1.78 mm (0.0701 in.) shim.

  1. With oil guide plate M and the appropriate size shim installed in the transmission housing, check the thrust clearance again to verify the clearance is within the standard.
