Seal Replacement

For most seal replacement procedures, the
pump should be completely removed from service and
clamped in a vise. If you are only replacing the reservoir
and/or reservoir seals, you do not have
to remove the
pump from it’s service location. The following instruc-
tions cover the complete disassembly of the pump. Your
pump repair may not require total pump disassembly.
