See VACUUM/PRESSURE TESTING and LU­
BRICATION before putting the pump back into
service.
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.
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 (49) and power ca­
ble (46) 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 (65 and 66) securing the head to the
motor housing (80). Raise the head for access to
the electrical connections.
Pull the male and female connector sleeves (31,
33, 35 and 37) apart, then pull the cable lead and
overload protector lead plugs (32), and run capaci­
tor lead plugs (36) from the motor and overload
protector lead receptacles (34) and run capacitor
receptacles (38).
Remove the assembled head, power cable (46)
and run capacitor (41). Remove the head O‐ring
(22).
To disconnect the power cable from the head, re­
move the hardware (50 and 51) securing the cable
chain (52) and handle (48) to the head. Unscrew
the cable locknut (40) and remove the beveled
washer (39). Pull the cable out of the head.
Remove the hardware (56 and 57) securing the run
capacitor holder (58), and remove the run capaci­
tor (41) from the head.
If necessary, remove the remaining hardware (50
and 51) securing the handle to the head.
To remove the start capacitor (59), pull the male
and female connector sleeves (27 and 29) apart,
then pull the capacitor lead plugs (28) from the re­
ceptacles (30). Disengage the hardware (63 and
64) and remove the capacitor and holder (62).
Remove the hardware (67 and 68), disconnect the
motor lead and remove the overload protector
(69).
Remove the hardware (70 and 71) and ring clamp
(21). Using caution not to strain any electrical
leads, lift the mounting plate (20) while guiding the
electrical leads through the grommet (23) to ac­
cess the centrifugal switch contact (73). Remove
the hardware (75, 76 and 77) and separate the mo­
tor lead terminals (74) from the contact.
Carefully remove the mounting plate; the bearing
shim (19) will become a free part. Disengage the
hardware (72) to remove the centrifugal switch
contact.
NOTE
The centrifugal switch actuator (17) is a press fit
onto the rotor shaft and cannot be removed until the
