RE-SHIMMING THE PINION HOUSING
The pinion housing shim may require replacement if the ring and pinion gear or pinion housing is replaced.
Pinion housing shims are available from 0.005” to 0.021” in increments of 0.001”. Locate the number printed on the
flat surface of the pilot bearing shaft of the pinion gear. It should be a number ranging from -5 to +5. This is the
amount in 0.001” increments to add to the “standard” shim. For example, if the number on the shaft is ‘-3’ then the
standard shim (0.015) plus ‘-3’ equals 0.012. The correct shim would be 0.012”.
If you cannot locate the number on the shaft, start with the standard shim and adjust as required per the contact
pattern chart below.
