Obtain the thickness of washer using the following formula.
Calculation formula:

T (mm) = (A - 15) - (B - 15) - (0.35 - 0.70)

[T (in) = (A - 0.591) - (B - 0.591) - (0.014 - 0.028)]

T: Washer thickness

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

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

15 mm (0.591 in): Thickness of ST

0.35 - 0.70 mm (0.014 - 0.028 in): Clearance

Select the washer matching value "T" obtained from step 4).
