rod horizontal with wooden support, if necessary. Remove
the seal washer (12), outlet valve seat (11), outlet valve
ball (10), outlet valve cage (9) lower packing set (4), lower
packing spring (8) and spring retainer (7).
6. Using a 1/2" extension bar attached to a 1/2" drive ratchet,
insert the end of the extension bar into the square opening
of the foot valve cage (17) inside the foot valve housing
(21). Unscrew and remove the foot valve cage along with
the wave washer (16) from the foot valve housing.
7. Remove the PTFE o-ring (3), foot valve ball (18), foot valve
seat (19), and seat o-ring (20) from the foot valve housing
(21).
8. Remove the o-ring (15) from the pump cylinder (14)

1. Place a new seat o-ring (20) into the groove in the bottom
of the foot valve housing (21).
2. Inspect the foot valve seat (19) for wear. If one side is worn,
flip the seat to the unused side. If both sides are worn,
install a new seat. Place the new or flipped seat (worn
side down) into the bore at the bottom of the foot valve
housing (21).
3. Place a new foot valve ball (18) onto the foot valve seat (19).
Using a 1/2" extension bar attached to a 1/2" drive ratchet,
insert the end of the extension bar into the square opening
of the foot valve cage (17) and screw the foot valve cage
into the foot valve housing (21). Torque the cage to 240
in.-lbs. (20 ft.-lbs.).
4. Place the wave washer (16) on top of the foot valve cage (17).
5. Insert a new PTFE o-ring (3) into the groove of the foot
valve housing (21). Lubricate the o-ring using oil or grease.
6. After soaking the leather packings in oil (preferably linseed
oil), reassemble the lower packing set (4). Place the set
onto the outlet valve housing (13) with the peak of the
"V" packings pointing down toward the hex on the outlet
valve housing.
All leather packings must be soaked in
i
CoolFlo hydraulic oil for 15–20 minutes before
installation. Soaking the packings too long will
cause the packings to swell and create difficulty
during reassembly.
7. Inspect the outlet valve seat (11) for wear. If one side is
worn, flip the seat to the unused side. If both sides are worn,
use a new seat. Insert the outlet valve cage (9) outlet valve
ball (10), new or flipped seat (worn side away from ball), and
a new seal washer (12) into the displacement rod (6).
8. Clean the threads on the outlet valve housing (13) and coat
the threads with blue Loctite #242. Make sure the Loctite is
only on the threads.
9. Place the lower packing spring (8) onto the outlet valve
housing (13) followed by the spring retainer (7).
10. Screw the displacement rod (6) and the outlet valve
housing (13) together. Tighten in a vise to 50 ft..-lbs. (68
Nm).
11. Insert the PTFE o-ring (3) into the upper grove of the
motor/pump block.
12. Insert the upper packing set (4) into the motor/pump block
with the peak of the "V" packings pointing up toward the
motor.
The packings must be soaked in hydraulic oil
i
before installation.
13. Place the upper packing spring (5) into the motor/pump
block with the small tapered end facing up toward the
motor/pump block.
14. Insert the displacement rod (6) up through the upper
packings in the motor/pump block.
15. Align the holes in the displacement rod (6) and the
hydraulic piston rod and insert the connecting pin (2).
Replace the retaining ring (1) over the connecting pin.
16. Thread the short threads of the pump cylinder (14) into the
motor/pump block and tighten with a strap wrench.
17. Place the o-ring (15) onto the top grove of the pump
cylinder (14).
18. Thread the foot valve housing (20) onto the pump cylinder
(14), tighten with a strap wrench and then back off to align
the siphon hose.
It is not necessary to over-tighten the foot valve
i
housing. O-ring seals perform sealing function
without excessive tightening. Full thread
engagement is sufficient. The foot valve housing
may be rotated backward up to 1/2 turn from full
engagement for convenient hose position.
For siphon hose attachment, it is critically
important that the threads of the siphon hose fit
snugly into the foot valve housing with the hose
assembly couplings PTFE taped and sealed to
prevent air leakage.
