PACKING REPLACEMENT (Continued)
FLUID PUMP REINSTALL
1. Loosen the packing nut and extend piston rod to fully up
position. Slip sleeve (187-047) over the piston rod.
2. Make sure that the spacer tubes (301-048) are in place.
3. Connect the connecting rod with uid the uid pump
by installing the coupling halves (189-046). Slide sleeve
over the coupling halves and secure with retaining ring
(189-048).
4. Secure the uid pump housing to the tie rods (100-328)
and screw locknuts with washers on loosely.
5. 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 disassembly of the
coupling. If any binding, loosen and retighten all the rod
locknuts to improve the alignment. Misalignment causes
premature wear of seal and packings.
6. Tighten the packing nut clockwise until resistance against
the packings can be felt. Turn it one full turn more.
7. 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.
8. Prime the unit and run at maximum pressure for several
minutes, then release the pressure and repeat step 6.
9. Fill the wet cup (packing nut) about 1/3 full of TSO
(Throat Seal Oil).
