SEAL REPLACEMENT INSTRUCTIONS
SPM25
Press the old seal out of the plate.
USE EXTREME CARE IN REMOVING THE
SEAL. Press it straight out of the
seal bore. If a punch and hammer are
used, move the punch around the seal
so that it causes even movement of the
seal down the bore. Do not mar
machined surfaces of the plate.
(Fig. 114)
After the seal has beer freed from
the bore, wash the seal plate in
solvent and blow it;dry. Inspect
the bore for significantly deep
grooves and scratches. Polish the
bore only with Number 400 Grit Emery
Cloth.
Wash and dry the plate again and
apply a liquid gasket sealer (such
as “Permatex”) to the bore surface.
