Calculate clearance "T" using the following formula.

Calculation formula:

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

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

T: Clearance

A: Depth from the ST upper face to the bearing end surface

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

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

15 mm (0.591 in): Thickness of ST
