14 Reassemble the outlet valve assembly into the piston rod
using the new o-ring, outlet valve seal, and outlet valve ball
that came with the repacking kit. Apply blue Loctite to the
threads of the outlet valve retainer. Torque the outlet valve
retainer to 150 in./lbs.
Never use a wrench on the piston rod itself. This could
cause damage to the piston and cause leakage.
15. Insert the new piston guide into the retainer nut. Thread
the retainer nut into the fluid section housing until it is
hand tight.
16. Slide the piston guide tool (included in the repacking kit)
over the top of the piston rod.
17. Insert the piston rod into the bottom of the fluid section
housing, through the lower packing, through the upper
packing, and out through the retainer nut. Using a rubber
mallet, tap the bottom of the piston rod lightly until the
piston rod is in position in the fluid section housing.
18. Using a wrench, tighten the retainer nut. Torque to 550-
600 in./lbs.
19. Slide the top of the piston rod into the T-slot on the slider
assembly.
20. Position the fluid section underneath the pump housing by
lining up the pump housing dowel pins with their
respective holes in the top of the fluid section housing.
Push the fluid section up towards the pump housing,
engaging the dowel pins, until the fluid section housing
rests against the pump housing.
21. Insert the two socket screws that secure the fluid section
to the pump housing and alternately snug, tighten, and
torque the screws to 400-440 in./lbs.
22. Reassemble the inlet valve using the new inlet valve seal,
o-ring, and inlet valve ball. Thread the inlet valve
assembly into the fluid section housing and torque to 350-
400 in./lbs.
23. Position the front cover over the pump housing. Secure
the front cover using the four front cover screws.
24. Using a 11/16” open-end wrench, attach the fluid hose to
the fitting on the back of the fluid section. Tighten
securely.
25. Turn on the sprayer by following the procedure in the
“Operation” section of this manual and check for leaks.
NOTE: Repacking kit P/N 755-165 is available. For
best results use all parts supplied in this kit.
NOTE: Make sure the raised lip on the bottom of the
lower packing assembly is fully outside the
packing around the piston rod after insertion
of the piston rod.
NOTE: Coat the piston guide tool and the piston rod
with grease before inserting them into the fluid
section housing.
NOTE: Use the T-slot on the slider assembly to hold
the piston rod in position while securing the
outlet valve retainer.
