CAUTION!
These parts can be easily damaged. Use care in
handling. Each part should be inspected
separately if parts are to be reused.
Always replace the O-rings.
Lubricate the small O-ring with petroleum jelly
and insert into the I. D. of the bronze rotating
ring.
Lubricate the large O-ring and place the O. D. of
the seal-stationary.
It is recommended that all shaft seal parts be
replaced. If parts are to be reused, they must be
protected from being damaged by the shaft
during removal. Remove the large retaining ring
located on the shaft end of the pump.
Remove the side opposite the tangs from the
groove first.
The rotating seal ring (bronze ring) is also held in
its position by the O-ring. It can be removed with
the help of two screw drivers.
