Fluid Pump Reinstall
1. Loosen the packing nut and extend piston rod to
fully up position. Slip sleeve over the piston rod.
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 rings.
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.
8. Start the pump and operate it slowly (at low engine
speed) to check the piston rod for binding. Adjust tie
rod lock nuts if necessary to eliminate binding.
9. Prime the unit and run at maximum pressure for
several minutes, then release the pressure and
repeat step 6.
10. Fill the wet cup (packing nut) with five drops of TSO
(Throat Seal Oil).
