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. Using 3/8" a hex
wrench, loosen and
remove the two
pump block mounting
screws.
3. Pull the pump block
down approximately
1/2" from the gear
box housing.
4. Slide the pump
block and piston
rod forward until the
piston rod is out of
the T-slot on the
slider assembly.
5. Slide the piston
rod out through the
bottom of the pump
block
6. Loosen and remove
the retainer nut and
piston guide from the
pump block.
7. Remove the upper and lower packings from the pump block.
8. Clean the pump block.
9. Locate the new upper and lower packings and pack the
areas between the packing lips with grease. Lubricate the
o-rings on the exterior of the packings with grease.
10. Inspect the piston rod for wear and replace if necessary.
11. Insert the upper packing into the top of the pump block
with the raised lip on the packing facing down.
12. Insert the piston guide into the retainer nut. Thread the
retainer nut into the pump block until it is hand tight.
13. Pre-form the lower packing using the lower packing sizing
tool (included in the repacking kit).
14. Insert the lower packing partially into the bottom of the
pump block so that the side that has the o-ring closest to
the face of the packing faces up.
Install upper packing
with raised lip
facing down.
Raised Lip
15. Push the lower packing into position using the lower
packing insertion tool (see Fluid Section Assembly parts
list for lower packing insertion tool P/N).
16. Inspect the piston rod for wear and replace if necessary.
NOTE: coat the piston guide tool and the piston rod
with grease before inserting them into the pump
block.
17. Place the piston insertion tool (included in the repacking
kit) over the top of the piston rod.
18. Insert the piston rod into the bottom of the pump block,
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 pump block.

rod.
20. Using a wrench, tighten the retainer nut into the pump
block. Torque to 300-360 in. lbs.
21. Slide the top of the piston rod into the T-slot on the slider
assembly.
22. Position the pump block underneath the gear box housing
and push up until it rests against the gear box housing.
IMPORTaNT: Make sure the transducer is aligned properly
with the hole in the pump block during reassembly.
Improper alignment may cause damage to the transducer
gasket.
23. Thread the pump block mounting screws through the
pump block and into the gear box housing. Torque to 400-
440 in. lbs.
24. Reassemble the foot valve assembly into the pump block.
NOTE: During reassembly, make sure the o-ring
between the pump block and foot valve housing
is lubricated with grease and in position.
25. Thread the siphon tube into the foot valve housing and
tighten securely. Make sure to wrap the threads on the
siphon tube with Teflon tape before assembly. Replace
the return hose into the clamp on the siphon tube.
26. Thread the return hose into the pump block and tighten
securely.
