Obtain the thickness of washer using the following formula to select the washer.

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

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

T: Shim thickness

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

B: Height from ST upper face to the drive pinion retainer mating surface 0.35 - 0.70 mm (0.014 - 0.028 in): Clearance
