1. Slide the upper packing (20) off the grey sizing/insertion
tool (towards the tip) and install into the top of the pump
housing with the raised lip (23) facing down. Save the
upper packing sizing/insertion tool for use in step 6.
2. Place the upper bushing (19) into the top of the housing
and tighten with an adjustable wrench (torque to 300-
360 in-lbs). This will drive the upper packing (20) into the
correct position.
3. Tilt the pump backwards so that it is laying on its back.
Remove the plastic wrap from the lower packing and red
pre-form tool.
Cut the plastic wrap with a scissors. Do not cut
plastic wrap with a utility knife as damage can
occur to the O-rings.
Attention
4. Slide the lower packing (21) off the pre-form tool (towards
the top). Insert the lower packing partially into the bottom
of the pump block so that the beveled edge (24) of the
packing faces up.
5. Thread the inlet valve housing (22) back into the bottom
of the pump housing by hand to drive the lower packing
into place. Once tightened as far as it will go, unthread
and remove again.
6. Place the grey insertion tool over the top of the piston
assembly (18). Coat the piston guide tool and the piston
rod with grease before inserting them into the pump
housing.
7. Insert the piston assembly into the bottom of the pump
block and push upward until the hole in the piston is
aligned with the hole in the yoke (17). Discard insertion
tool.
Make sure the piston is inserted precisely through
the middle of the upper and lower packing.
Coming in at an angle will bump the piston into
Attention
the sides of the packings and cause damage.
8. Apply any type of household grease to the piston and yoke
area to prolong life. Apply to the holes in the yoke where
the dowel (16) is inserted.
9. Install the dowel pin (16) to connect the yoke (17) to the
piston (18). The piston may have to be moved up or down
to do this.
10. Install the yoke screw (14) and washer (15) to secure the
dowel pin.
11. Turn pump right side up and apply a few drops of Piston
Lube or light household oil between the top nut (19) and
piston (18). This will prolong the seal life.
12. Reinstall the inlet valve assembly (22). Tighten by hand
until it cannot be tightented further, and then tighten
another 1/2 turn with a wrench. This will automatically
secure the lower packing (21) into place.
13. If equipped, replace pusher assembly (26) onto inlet valve
assembly.
14. Install front cover and three screws.
15. Reinstall the pressure control knob. Secure with the screw.
16. Reinstall the suction tube and return tube.
If the knob bottom (25) has been removed
i
from the pressure switch assembly, it must be
re-calibrated prior to reinstallation.
