pump and set the drive assembly aside.
4. Remove the two 3" socket
head caps crews using a 1/4"
allen wrench. Separate the
pump back plate and piston
assembly from the pump body
(see
Figure R-2 ).
5. If the piston assembly
remained with the pump back
plate when it was removed,
pull the piston out of the back
plate and set it aside. If the
piston stayed in the main
pump body, pull it out of the
cylinder. If the piston assembly
is difficult to remove from the
pump body, insert a small
allen wrench or Phillips screwdriver through the coupling pin hole. This will provide a “t-
handle” with a better grip for extracting the piston
assembly.
Be aware not to damage the surface of the
piston shaft.
6. Remove the large o-ring (8012588) from its groove in
the side of the pump back plate that faces the pump
body. Remove the wiper block and spacer (if present)
from the pump back plate. Use needle-nosed pliers to
pull the old wiper block seal out of the wiper block. See
Figure R-3
. ( Note: This seal is usually damaged during
removal. Be sure you have a replacement on hand
before removing it.)
7. From the side of the pump back plate that contained the large o-ring, insert a round drift of
slightly smaller diameter than the hole for the piston shaft. ( Note : a small socket on an
extension or a wooden dowel makes a suitable drift). Tap the drift with a mallet to drive the
two backup washers, two piston shaft seals and the piston shaft bushing out of the pump
back body. See
Figure R-4 .
8. Remove the remaining two 3/4" socket head cap
screws from the check valve plate using a 1/4"
allen wrench. Separate the check valve plate from
the pump body. If it is difficult to remove, try
rotating the check valve plate 90°. This provides a
better grip for pulling the check valve plate from the
pump body.
9. After the check valve plate has been separated from
the pump body, the membrane tube plug will
remain in either the check valve plate or the pump
end of the membrane housing. Use one of the following procedures to remove it:
A. If the membrane tube plug remains in the membrane housing, insert a hard, thin edge
(e.g., a dull pocket knife) between the tube plug and the fiberglass molding of the
membrane housing. Work the blade sideways to pry the tube plug out slightly, until
there is enough of a gap between the tube plug body and the membrane housing to
