- Obtain the thickness of transfer drive gear shim using the following formula to select one to three transfer drive gear shims.
T mm = A - B - (0.05 - 0.25)
[T in = A - B - (0.002 - 0.01)]
T: Shim thickness
A: Height from the ST upper face to the ball bearing catch surface
B: Height from ST to transmission case mating surface
0.05 - 0.25 mm (0.002 - 0.01 in): Clearance
