ing. Do not disassemble the motor unless it is nec-
essary and a clean, well-equipped shop is avail-
able.

NOTE

It is recommended that a pump with a defective mo-
tor be returned to Gorman-Rupp, or to one of the
Gorman-Rupp authorized Submersible Repair
Centers.

The electrical power used to operate
this pump is high enough to cause inju-
ry or death. Make certain that the plug
on the pump power cable is discon-
nected from its receptacle.

Carefully inspect any O-rings or gaskets before re-
moval and cleaning to determine if a proper seal
and compression existed prior to disassembly. If
sealing was faulty or questionable, the cause must
be determined and corrected before reassembly.
Replace any parts as required.

Head And Power Cable Removal

Total disassembly of the head (21) and power ca-
ble (31) is not always required. Disassemble and
replace only the parts proven defective by inspec-
tion or testing. See Electrical Testing in
TROUBLESHOOTING.

The head and power cable may be serviced with-
out disassembling the motor housing or pump
end, or without draining the oil from the motor cav-
ity. However, the oil must be drained before at-
tempting to disassemble the motor housing and
components.

Secure the pump in an upright position. Remove
the hardware (18 and 19) securing the head to the
motor housing (10). Raise the head for access to
the electrical connections.

Pull the male and female connector sleeves (26,
28, 40 and 42) apart, then pull the cable lead plugs
lead plugs (41) from the overload protector and
ground lead receptacles (43).

Remove the assembled head and power cable.
Remove the head gasket (50).

To disconnect the power cable from the head, re-
move the hardware (32 and 33) securing the cable
lock (30) and handle (36) to the head. Remove the
hardware (37 and 38) and pull the cable out of the
head.

If necessary, remove the remaining hardware (32
and 33) securing the handle to the head.

To remove the start capacitor (22), pull the male
and female connector sleeves (26 and 28) apart,
then pull the capacitor lead plugs (27) from the re-
ceptacles (29). Remove the hardware (24 and 25)
securing the start capacitor holder (23), and re-
move the start capacitor from the mounting plate
(17).

Remove the hardware (48 and 49), disconnect the
motor lead and remove the overload protector
(47).

Using caution not to strain any electrical leads, lift
the mounting plate (17) while guiding the electrical
leads through the grommet (20) to access the cen-
trifugal switch contact (14). Remove the hardware
(12 and 13) and separate the motor lead terminals
(11) from the contact.

Carefully remove the mounting plate; the bearing
shim (45) will become a free part. Disengage the
hardware (15 and 16) to remove the centrifugal
switch contact (14).

NOTE

The centrifugal switch actuator (51) is a press fit
onto the rotor shaft and cannot be removed until the
rotor is removed.

See Head And Power Cable Installation if no fur-
ther disassembly is required.

Rotor And Shaft Removal

See PUMP END DISASSEMBLY and remove all
pump end components and Head And Power
Cable Removal and remove the head and cable.

Carefully lift the rotor/shaft (53) with assembled
bearings (45 and 47) and centrifugal switch actua-
tor (51) from the motor housing. Use caution to pre-
