Calculation formula:

Select the ball bearing shim from the table to adjust clearances within 0.05 - 0.25 mm (0.0020 - 0.0098 in).

When clearances are 0.05 mm (0.0020 in):

T (mm) = B - A + 0.23

[T (in) = B-A+ 0.0091]

When clearances are 0.25 mm (0.0098 in):

T (mm) = B - A + 0.03

[T (in) = B - A+ 0.0011]

T: Shim clearance

A: Height from the mating surface of the AT main case to the ball bearing outer ring end surface

B: Depth from mating surface of extension case to ball bearing outer ring contact surface
