8. Place the entire assembly into the outlet body with the female side of the packing set facing
down.
9. Set the guide bearing into the outlet body.
10. Screw the packing nut into the outlet body only up to two or three
threads; do not tighten at this time.
Note If you have converted to a Magnapak fluid section, the
configuration is slightly different. The packing set and
piston cups are replaced with a bushing and cup seals.
You will need to lubricate parts using PAT-LS-OIL or
Gun Oil on the parts and insert as shown.
11. Place the new O-ring on to the piston adapter and thread into the
piston rod.
12. Slide one piston cup onto the piston body with the open side of the
cup facing up.
13. Slide the piston cup back-up ring groove side up against the piston
cup.
14. Install the second piston cup open side down against the backup ring.
15. Slide the spacer ring against the second piston cup.
16. Coat the threads of the piston nut and screw it onto the piston body.
17. Place a new chrome ball into the piston body.
Note Be careful not to drop, dent, or scratch the chrome ball. Damage to the ball will
cause the unit not to function properly.
18. Set the piston ball spring into the piston body with the small end against the ball.
19. Coat the threads of the piston body and screw it onto the adapter.
20. Tighten the piston nut and the piston body.
21. Slide the piston rod up through the outlet body and then tighten the packing nut enough to
hold the rod in place.
22. Install a second new chrome ball, then the foot valve guide into the foot valve.
23. Compress the ball stop and insert it into the foot valve groove.
24. Slide a new O-ring onto the cylinder ends and lubricate with red grease.
25. Position one end of the cylinder into the foot valve.
26. Use lithium grease on the pump cylinder tie rod threads and screw into the outlet body (if
they were removed).
27. Slide the cylinder with the foot valve over the piston rod assembly and start the hex nuts
onto the ends of the tie rods.
28. Tighten the hex nuts uniformly until wrench tight.
29. Use a ¼” metal rod or screwdriver to tighten the packing nut.
