Using the following formula, calculate clearance "T" to select a shim.

Formula: T mm = (C - 15) - ((A - 15) - B)

[T in = (C - 0.591) - ((A - 0.591) - B)]

T: Clearance

A: Height from the ST upper face to the converter case mating surface

B: Depth from the converter case cover upper face to the bearing catch surface

C: Depth from the ST upper face to the bearing end face

15 mm (0.591 in): Thickness of ST
