MAINTENANCE & REPAIR PAGE E - 9
MOTOR DISASSEMBLY
Disassembly of the motor is rarely required except
to replace the rotor, stator, bearings or motor hous­
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 before ser­
vicing.
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 (58) and power ca­
ble (55) 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 (81 and 82) securing the head to the
motor housing (97). Raise the head for access to
the electrical connections.
Pull the male and female connector sleeves (40
and 42) apart, then pull the lead plugs (41) from the
auto control device (78) out of the cable lead recep­
tacles (43). Pull the green ground lead plug (41)
out of the ground lead receptacle (43). Disengage
the nut securing the white wire from the socket
housing (69) to the on point assembly (31) and
separate the wire from the on point assembly.
Pull the male and female connector sleeves (44
and 46) apart, then pull the capacitor lead plugs
(45) from the stator lead receptacles (47).
Remove the assembled head, power cable (55)
and run capacitor (50). Remove the head O‐ring
(26).
To disconnect the power cable from the head, re­
move the hardware (59 and 69) securing the cable
chain (64) and handle (57) to the head. Unscrew
the cable locknut (49) and pull the cable out of the
head.
Remove the hardware (65 and 66) securing the run
capacitor holder (67), and remove the run capaci­
tor (50) from the head.
If necessary, remove the remaining hardware (59
and 60) securing the handle to the head.
If the start capacitor (72) or auto control device (78)
require replacement, pull the male and female con­
nector sleeves (36 and 38) apart, then pull the lead
plugs (37) of the wires from the start capacitor out
of the receptacles (39) on the blue C1 leads from
the stator. Disengage the hardware (79 and 80) se­
curing the auto control device to the mounting
plate (24). Turn the auto control device over, disen­
gage the hardware (76 and 77) and remove the
holder (75) and capacitor from the auto control de­
vice.
To remove the auto control device, separate any re­
maining connector sleeves, plugs and recep­
tacles. Separate the pin and socket housings (69
and 71). If necessary, remove the socket and pin
contacts (68 and 70).
Remove the hardware (83 and 84), disconnect the
motor lead and remove the overload protector
(85).
Remove the hardware (86 and 87) and ring clamp
(25). Using caution not to strain any electrical
