and pump cylinder (11) with strap wrench.
2. Slide the retainer ring (1) up with a small screwdriver, then
push the connecting pin (2) out.
3. Pull displacement rod (6) through the lower cavity of the
pump block.
4. Remove the pump block,
PTFE
o-ring (3), upper packing
spring (5), and upper packing set (4).
5. Hold displacement rod (6) in a vise by the flats at the top of
the rod and remove piston seat (10) with a wrench while
holding the displacement rod horizontal with wooden
support, if necessary. Remove ball (9), lower packing set
(4), lower packing spring (8), and spring retainer (7).
6. Remove ball cage (13),
PTFE
o-ring (3), and ball (14).
7. Replace connecting pin (2) and retainer ring (1) .
8. Remove o-ring (12) from pump cylinder (11)
Reassembly
1. Place ball (14) into foot valve (15), followed by ball cage
(13).
2. Insert
PTFE
o-ring (3) into lower groove of foot valve (15).
3. Place lower packing set (4) onto piston seat (10) with the
peak of the “V” packings pointing down toward the foot
valve.
4. Clean the threads on piston seat (10) and coat the threads
with blue Loctite. Make sure no Loctite is on the seat.
5. Place ball (9) onto piston seat (10).
6. Place lower packing spring (8) onto piston seat (10),
followed by spring retainer (7).
7. Screw displacement rod (6) and piston seat(10) together.
Tighten in a vise to 75 ft./lbs.
8. Insert
PTFE
o-ring (3) into upper grove of pump block.
9. Insert upper packing set (4) into pump block with the peak
of the “ V” packings pointing up toward the motor.
10. Place upper packing spring (5) into the pump block with the
small tapered end facing up toward the pump block.
11. Insert displacement rod (6) up through the upper packings in
the pump block.
12. Align the holes in displacement rod (6) and the hydraulic
piston rod and insert connecting pin (2).
13. Thread the short threads of pump cylinder (11) into the
pump block and tighten with a strap wrench.
14. Place o-ring (12) onto the top grove of pump cylinder (11).

NOTE: It is not necessary to over-tighten the foot valve.
O-ring seals perform sealing function without
excessive tightening. Full thread engagement is
sufficient.
For siphon tube attachment, it is critically
important that the threads of the siphon tube fit
snugly into the foot valve with the tube
PTFE
taped and sealed to prevent air leakage.
NOTE: Packings must be soaked in oil before
installation.
