Pinion shim thickness (T) =
M - 24.50
Example:

If "T" is 26.06 mm,
T =26.06 - 24.50
=1.56
4. Select the pinion shim(s) (T) as follows.

Available shim thicknesses:
0.70, 0.75, 0.80 and 0.85 mm
Example:
If "T" is 1.65 mm, then the pinion shim is
1.60 mm.
If "T" is 1.56 mm, then the pinion shim is
1.55 mm.
