PUMP ASSEMBLY/DISASSEMBLY
MODEL NOS. 3P740A 2-STAGE PUMP
AND 4RJ96A 3-STAGE PUMP
(For assembly instructions for Single
Stage pump Model Nos. 4P037, 4P038,
and 4P039, turn to Page 14).
1. Turn OFF power to pump at
disconnect switch. Disconnect power
lines from pressure switch.
2. Remove the two cap screws holding
the pump to the flange adapter.
Don’t disturb the piping in the well.
3. Remove the flange adapter gasket
and scrape the surfaces clean.
4. Leaving the tubing in place, unscrew
and remove the straight barbed
fitting at the pressure switch.
5. Draw an index line down the side of
the pump with a marker to help
alignment during reassembly. Mark
the pump from the motor to the
base volute (See Figure 11).
6. Turn the pump upside down on the
bench and block it. Remove the four
cap screws from the base. With a
mallet, tap upward on the base to
loosen it. Lift the base off of the
intermediate volute (See Figure 12).
7. To reduce the chance of dropping
the pump onto your foot, lay it down
on the bench; block it so it won’t roll.
8. Hold the motor shaft with pliers or
vice grips through the opening in the
pump adapter. Unscrew the impeller
nut from the end of the shaft (See
Figure 13).
9. The impellers are keyed to the shaft
and do not unscrew. Insert two
screwdrivers on opposite sides under
the exposed impeller and pry the
impeller off (See Figure 14) to
remove it.
10.Carefully tap a small screwdriver or
thin bladed chisel in between the
intermediate volute and the pump
adapter in two or three places
around the pump to separate the
castings (See Figure 15). Do not mar
the sealing surfaces; do not break
pieces out of the adapter or volute –
the castings are easily damaged.
