Shimming Process
Installation Information
This skim kit is to replace
the bearing spacer within the
pump housing. If the housing,
drive shaft, shaft bearings or
end cover is replaced during
servicing, the original bearing
spacer can no longer be used to
assure proper bearing set.
Shimming procedures
1. Measure the thickness of
the existing
bearing spacer
2. To obtain a starting point,
stack shims to a few
thousandth of an inch less
than the measurement
of existing bearing spacer
Then insert shims into the
end cover in the same
location as the removed
.
bearing spacer
3. Assemble the housing
(without interface 0-ring
seals), shaft bearings,
shaft and end cover. Install
the end cover cap screws
and torque to 61±6.1 Nm.

4. Using a dial indicator,
. measure drive shaft end
play. Target shaft end play
range is .0005" to .003"
(.013 to .08 mm). Add or
remove shims to achieve
proper shaft end play. If no
.
movement of the shaft is
observed, shims will need
to be removed and steps 3
and 4 repeated.
5. Finish the assembly of the
pump.
