INSPECTION
Make sure the ball bearing and gear is not deformed or damaged.

ADJUSTMENT
1) Using the ST, measure the height "A" from the AT main case mating surface to ball bearing outer ring contact surface.

2) Using the ST, measure the depth "B", which is from mating surface of extension case to ball bearing outer ring contact surface.

3) 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
