Kits Required:
• UMP Replacement Kit (P/N 144-327-4)
• Pigtail (P/N 410156-001)

Figure 29. Extractable Lock-Down Nuts
Confirm that the lifting eyebolt is properly torqued to 10 ft-lbs (13.6 N•m) with a
minimum of 6 full threads installed. Occasionally, eyebolts are removed after pump
installation and corrosion m ay occur in the threaded areas of the wiring
compartment cover (eyebolt plug) and the eyebolt. If corrosion has occurred, the
cover and eyebolt should be replaced.
3.
Utilize the lifting eyebolt to lift out the extractable unit and place it on a clean surface.
Removal of the
extractable section of the pump must be conducted with caution.
Make certain that the extractable
section remains centered within the riser pipe and that no portion of the extractable binds during the removal
process. If binding occurs during removal, stop and determine the cause of the binding and correct the
situation before proceeding with removal.
4.
Remove the UMP by removing the four bolts holding the discharge head as shown in Figure 23 on page 25.
Discard the old gasket and fasteners.
5.
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
reduced.
