Disassembly
1. Remove siphon tube assembly. Unthread foot valve (16)
and pump cylinder (12) 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
motor pump block.
4. Remove the motor pump block, 37)( 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 displacement rod and remove piston seat (11) with
wrench while holding the displacement rod horizontal with
wooden support, if necessary. Remove ball (10), lower
packing set (4), lower packing spring (9), sleeve (8), and
spring retainer (7).
6. Remove ball cage (14), 37)( o-ring (3), and ball (15).
7. Replace connecting pin (2) and retainer ring (1) .
8. Remove o-ring (13) from pump cylinder (12)
Reassembly
1. Place ball (15) into foot valve (16), followed by ball cage
(14).
2. Insert 37)( o-ring (3) into lower groove of foot valve (16).
3. Place lower packing set (4) onto piston seat (11) with the
peak of the “V” packings pointing down toward the foot
valve.
4. Clean the threads on piston seat (11) and coat the threads
with blue Loctite. Make sure no Loctite is on the seat.
5. Place ball (10) onto piston seat (11).
6. Place lower packing spring (9) onto piston seat (11),
followed by sleeve (8) and spring retainer (7).
7. Screw displacement rod (6) and piston seat (11) together.
Tighten in a vise to 75 ft./lbs.
8. Insert 37)( o-ring (3) into upper grove of the motor pump
block.
9. Insert upper packing set (4) into the motor pump block with
the peak of the “V” packings pointing up toward the motor.
10. Place upper packing spring (5) into the motor pump block
with the small tapered end facing up toward the motor pump
block.
11. Insert displacement rod (6) up through the upper packings in
the motor 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 (12) into the
motor pump block and tighten with a strap wrench.
14. Place o-ring (13) onto the top grove of pump cylinder (12).
15. Thread foot valve (16) onto pump cylinder (12), tighten with
a strap wrench, then back off to align the siphon hose.

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. The foot valve 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 with the hose
assembly couplings PTFE taped and sealed to
prevent air leakage.
NOTE: Packings must be soaked in oil before
installation.
NOTE: Packings must be soaked in oil before

NOTE: Use 37)( tape on all threaded pipe connections.
