Calculate the following formula.
T (mm) = A - B - (0.05 - 0.25)

[T (in) = A - B - (0.002 - 0.01)]

T: Moving distance of reduction drive gear

A: Depth from the ST upper face to the reduction drive gear end surface

B: Depth from the ST upper face to the reduction drive gear end surface

0.05 - 0.25 mm (0.002 - 0.01 in): Clearance
Select one to three reduction drive gear shims so that the total thickness meets the value obtained from step 5).
