5. Remove two retaining rings (4) and slip the sleeve of
the coupling down and remove both coupling
halves. This will disconnect fluid pump from the con-
necting rod.
6. Using a 7/8” box wrench disconnect the high pres-
sure fluid line from the pump.
7. Using a 9/16” wrench, unscrew the two tie rod lock-
nuts (10).
8. Pull the pump off the tie rods.
Fluid Pump Reinstall
1. Loosen the packing nut and extend piston rod to
fully up position.
2. Insert one of the retaining rings through the packing
nut and rest the sleeve on top of it.
3. Connect the connecting rod with the fluid pump by
installing the coupling halves. Slide sleeve over the
coupling halves and secure with retaining ring.
4. Remove the retaining ring from the packing nut and
insert into coupling halves.
5. Secure the fluid pump housing to the tie rods and
screw locknuts with washers on loosely.
6. Tighten the tie rod locknuts evenly to 30 ft. lb.
NOTE: After all the rod locknuts are tight, the alignment
of both rods should allow easy assembly and disassem-
bly of the coupling. If any binding, loosen and retighten
all the rod locknuts to improve the alignment. Misalign-
ment causes premature wear of seal and packings.
7. Tighten packing nut clockwise until resistance
against the packings can be felt. Turn it one full turn
more.
