Repacking the Fluid Section
1. Remove the foot valve assembly using the steps in the
“Servicing the Valves” procedure above.
NOTE: The outlet valve does not need to be
disassembled from the piston rod for this
procedure.

2. Slide the retaining
ring up on the slider
assembly to expose
the connecting pin.
3. Push the connecting
pin forward through
the slider assembly
and piston. The
connecting pin will
fall into a recessed
area of the gear box
housing where it can
be retrieved.
4. Using 3/8” a hex
wrench, loosen and
remove the two pump
manifold mounting
screws.
5. Pull the pump
manifold down off of
the gear box housing.
6. Slide the piston
rod out through the
bottom of the pump
manifold.
7. Loosen and remove
the retainer nut and
piston guide from the
pump manifold.
8. Remove the upper
and lower packings
from the pump
manifold.
9. Clean the pump manifold and install the new upper and
lower packings. Refer to the illustration below for proper
packing orientation.
Large Beveled Edge
Install upper packing
with raised lip
facing down.
Raised Lip
Install lower packing
with large beveled
edge facing up.
10. Inspect the piston rod for wear and replace if necessary.
11. Insert the piston guide into the retainer nut. Thread the
retainer nut into the pump manifold until it is hand tight.
12. Slide the piston guide tool (included in the repacking kit)
over the top of the piston rod and insert the piston rod
through the bottom of the pump manifold. Using a rubber
mallet, tap the bottom of the piston rod lightly until the
piston rod is in position in the pump manifold.
NOTE: coat the piston guide tool and the piston rod
with grease before inserting them into the pump
manifold.
13. Using a wrench, tighten the retainer nut securely.
14. Position the pump block underneath the pump housing
and push up until it rests against the pump housing. When
the connecting pin hole on the piston rod lines up with the
hole in the slider assembly, insert the connecting pin.
15. Slide the retaining ring down over the connecting pin.
IMPORTaNT: Make sure the transducer is aligned properly
with the hole in the pump manifold during reassembly.
Improper alignment may cause damage to the transducer
gasket.
16. Thread the pump manifold mounting screws through the
pump manifold and into the gear box housing. Tighten
securely.
17. Reassemble the inlet valve assembly into the pump
manifold.
18. For Upright Cart units, thread the siphon tube into the inlet
valve and tighten securely. Make sure to wrap the threads
on the down tube with PTFE tape before assembly.
Replace the return hose into the hose clip on the siphon
tube.
19. For Low Boy cart units, insert the elbow on the suction set
assembly into the bottom of the inlet valve housing. Push
the retaining ring up into the groove inside the inlet valve
housing to secure the suction set assembly in position.
Push the return hose onto the return hose fitting on the
pump manifold and secure in position with the return hose
clamp.
20. Place the front cover on the gear box housing and secure
in position using the four front cover screws.
21. Turn on the sprayer by following the procedure in the
“Operation” section of this manual and check for leaks.
NOTE: Repacking kit P/N 0551677 is available. For best
results use all parts supplied in this kit.
