  4. Obtain the thickness of washer using the following formula.

    Calculation formula:

    T (mm) = (A - 15) - (B - 15) - (0.75 - 0.95)

    [T (in) = (A - 0.591) - (B - 0.591) - (0.030 - 0.037)]

    T: Washer thickness

    A: Depth from the ST upper face to the washer catch surface

    B: Height from the ST upper face to the mating surface of the intermediate case

    15 mm (0.591 in): Thickness of ST

    0.75 - 0.95 mm (0.030 - 0.037 in): Clearance

  5. Select the washer to meet the value "T" obtained from step 4.
