Disassembly:
1. Before beginning disassembly, run the watermaker and stop it when the piston shaft is at its
farthest point of travel away from the pump (toward the drive assembly). This provides enough
room for sliding the rubber boot
back toward the pump in Step 3.
2. Use the 11/16" open-end
wrench to disconnect the two
high-pressure hoses (coming
from the membrane housing)
from the tube connectors on the
check valve plate and the valve
assembly. Loosen the hose
clamps and remove the
reinforced plastic seawater
intake and reject brine hoses.
See Figure R-1.
3. Use the 1/2" open-end wrench
to remove the four hex nuts
securing the pump back plate to
the drive assembly. Then pull the
pump away from the drive assembly to expose as much of the piston shaft as possible. Slide the
black rubber boot on the piston shaft toward the pump to expose the shaft coupling pin. Use a
small screwdriver or allen wrench to push the coupling pin out of the shaft. (Note: the coupling
pin is a loose fit and may fall out
on its own. Do not lose it.) Sepa-
rate the pump from the drive
assembly and set the drive
assembly aside in a safe place.
Slide the black rubber boot off
the piston shaft. Move the pump
to a clean work surface for
further disassembly. See Figure
R-2.
4. Use a large crescent wrench to
remove the plastic intake hose
barb from the check valve plate.
Use the same wrench to loosen
the outlet adaptor in the check
valve plate. Then use the 1/4"
allen wrench to remove the six
sockethead flange bolts that hold
the check valve plate to the
pump body. Separate the check
valve plate from the pump body and remove the large o-ring (8012532) seal between them. See
Figure R-2.
