INSPECTION

Check the ball bearing and gear for break or damage.

ADJUSTMENT

1) Using the ST, measure the height "A" from the AT main case mating surface to the 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.
ST 499575400 GAUGE





3) Calculation formula:
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 + 0.0012]
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

Specification:
0.05 - 0.25 mm (0.0020 - 0.0098 in)

4) Select the reduction gear shim so that the clearance is within the specified range.
