Selecting Pinion Housing Shims
The pinion housing shims are available in thickness from 0.005" to 0.021", in increments
of 0.001", to correctly position the pinion gear. However, the standard shim thickness is
0.015" thick.
The following numbering system is used on pinions to indicate the amount you must
add or subtract from the standard shim in order to correctly position the pinion gear.
Locate the number on the flat surface on the small shaft at the end of the pinion gear.
Match the number with the shim required.
