Service And Repair
7. Remove the packer wiring compartment cover. Remove and discard the O-ring from the cover and set aside
the cover. Observe the three wiring connections sealed in the compartment. Make a note of which wire from
the packer connects to which wire from the pigtail (it should be like colored wires connecting to like colored
wires). Cut the wires close to the epoxy-filled bags and discard the bags.
8. Look at the end of the discharge head. Pull the pigtail connector out of its socket in the discharge head and
remove and discard the pigtail. Remove the O-ring in the sidewall of the connector's socket in the discharge
head.
9. Get the new pigtail assembly and uncoil the pigtail so it lays flat.
10. Get a 0.551'' ID x 0.070'' wide O-ring from the Hardware/Seal Kit. Lubricate the O-ring with petroleum jelly
and insert it in the sidewall of the connector's socket in the end of the discharge head.
11. Push the pigtail wires into the connector's socket until they exit into the packer's wiring compartment. At the
discharge (connector) end of the pigtail, rub some petroleum jelly over the connector's outside surface and
push it into its socket in the discharge head. Take care to align the connector index tab with the notch in the
socket as shown in the drawing on the right in Figure 28 on page 32.
12. Place the new gasket from the UMP replacement kit on the new UMP so that all the holes align.
Gaskets from competitive UMPs will not seal properly and performance will be re-

duced.
13. Align the UMP positioning dowel so it inserts in the proper hole in the discharge head (again ref. Figure 28 on
page 32) and push the UMP into position using hand force only. The UMP should be snug against the
discharge head prior to installing the UMP retaining bolts.
WARNING
Use hand force to push the UMP onto the discharge head. If the UMP does not seat
snug against the discharge head, remove the UMP and correct the problem.
14. Install the four UMP retaining bolts and lock washers. Snug and then torque the bolts using a cross pattern
technique to 7 ft-lbs (11 N•m).
WARNING
Do not use the bolts to pull the UMP into position. Use the cross pattern to snub and
torque the bolts. Do not over torque the bolts. Not following these instructions may ca-
sue parts to fail.
15. Carefully pull on the pigtail wires where they exit the packer wiring compartment. Cut pigtail wires
approximately 8 inches (200 mm) beyond top of packer. Visually inspect the wire insulation to make sure it is
undamaged.
16. There will be three wires to the male connector installed in the packer's housing and three from the three-wire
pigtail from the UMP. Strip insulation off all six wires 5/16 inches (8 mm).
17. Connect like colored wires from the UMP to like colored wires to the male connector with supplied butt splice
connectors and making a mechanical crimp. (Note: refer to notes made in Step 7 before connecting these
wires). Pull on each wire to verify a reliable crimp was achieved.
