HOW TO DISMANTLE (HR SHALLOW WELL)
1.
Pull disconnect switch. Disconnect power lines from
pressure switch.
2.
Remove the two cap screws holding the pump to the flange
adapter. Do not 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 a line down the side of the pump with a market to help
alignment during reassembly. Mark the pump from the motor to
the base volute (see Figure 16).
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 17).
7.
To reduce the chance of dropping the pump onto your foot, lay it
down on teh 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 off the end of the
shaft (see Figure 18).
9.
The impellers are keyed to the shaft and do not unscrew. Inset
two screw drivers on opposite sides under the exposed impeller
and pry the impeller off (Figure 19) to remove it.
10. Carefully tap a small screwdriver or thin bladed chisel in between
the intermediate volute and hte pump adapter in two or three
places around the pump to separate the castings (Figure 20).
Do not mar the sealing surfaces; do not break pieces out to the
adapter or volute - the castings are easily damaged.
11. Remove the intermediate volute and slide the impeller spacer off
of the shaft
12. Remove the impeller. Do not disturb the shaft keys if you are only
replacing the seal.
13. Rotate the seal spring retainer cup so that the slot lines up with
the shaft keys; remove the cup and spring.
14. Remove the two cap screws holding the adapter bracket
to the motor.
15. With two screwdrivers on opposite sides of the pump, carefully
pry the pump adapter away from the motor. This will pull the
seal off of the motor shaft. Use caution to make sure that the
ceramic seal does not dig into the shaft and scratch the shaft's
sealing surface.
