6. Grease piston packings and sleeve top edge.
7. Carefully slide piston assembly into top of sleeve.
8. Grease top inch or two of piston rod that will go
through the cylinder throat packings.
9. Grease o-ring (315m) and place on sleeve. Slide
sleeve/piston rod assembly into bottom of cylinder.
Replace o-ring (315n) if desired. NOTE: O-ring
(315n) is not required for safe pump operation.
10. Reassemble intake valve with new o-ring (315a),
seat (309a) and ball (315b). Seat may be flipped
over and used on other side. Clean seat thoroughly.
Place intake spring (315r) on top of ball guide (317).
11. Install intake valve on cylinder. If a wrench is used,
torque to 200 +/- 15 ft-lb. If a wrench is not used, be
sure intake valve is tight against cylinder.
12. Torque seal and packing nut (312) down onto throat
adjustment spacer (302) to 140 +/- 10 in-lb. Remove
throat adjustment spacer (302) when pump pack-
ings begin to leak after too much use. Then tighten
packing nut down until leakage stops or lessens.
This allows approximately 100 gallons of additional
operation before a repacking is required.
