valve seat in the bore for the intake check valve assembly. It too should be installed with the
beveled edge of the valve seat facing outward, or against your finger.
3. With the o-ring side facing down (facing the valve seat), lower one of the poppet valves (they are
both identical) into the bore for the reject check valve assembly. The poppet valve should be level
and in the center of the valve seat at the bottom of the bore, with the narrow stem facing up.
Lower a new valve spring over the stem of the poppet valve. Next, lower a valve retainer into the
bore. Note that one side of the retainer has a
circular groove that must engage the end of the
valve spring. Finally, replace the o-ring on the
outlet adaptor and screw the adaptor into the
reject check valve bore and tighten. The tube
fitting should still be installed in the outlet
adaptor. If not, install and tighten. Be careful not
to damage the o-ring on the tube fitting. This o-
ring is not included in the RSK. Test your
installation by inserting a small screwdriver into
the hole for the reject check valve on the side of
the check valve plate opposite the tube fitting.
The reject poppet valve should move up and
down freely.
4. Refer again to Figure R-3. Working from the other side of the check valve plate, use the same
procedure to assemble the intake poppet valve, valve spring and valve retainer. After testing the
action of the intake check valve, install the plastic intake hose barb.
5. Lubricate a new o-ring (8012532) with silicon grease and install it into its groove in the pump
side of the check valve plate. Taking care that the intake check valve components do not fall out of
their bore, bring the check valve plate and the pump body together, align them, and install the six
sockethead flange bolts to hold the assembly together. Tighten these fasteners snugly. (If a torque
wrench is available, tighten to approximately 120140 in.-lbs.) See Figure R-6.
6. Lubricate the inside of the cylinder in the pump body with silicon grease. Insert the piston
assembly through its hole in the pump back plate and slide it as far as it will go toward the pump
back plate, as shown in Figure R-7. Install the two o-rings (8012830) and (8012444) in their
grooves in the pump back plate. Make
sure the relief valve spring is installed in
the pump body. Bring the pump back
plate and pump body together
carefully, first guiding the piston into the
cylinder in the pump body, and then
pressing the back plate as close as
possible to the pump body. Install the
four sockethead flange bolts and tighten
snugly (approximately 120140 in.-
lbs.).
