Inspect removed parts at disassembly to determine if they can
be reused. Cracked castings should never be reused. Scored or
worn pump shafts should be replaced. Gaskets should be
replaced at reassembly simply as a matter of economy. They are
much less expensive to replace routinely than to replace
individually as the need arises. While motors and motor
controls are often returned to the manufacturer for repairs it is
usually more practical and economical to repair the pump at the
job site or the pump repair shop.
Cleaning of most parts can be accomplished with the use of
clean rags.
