Seal Removal
NOTE
The seal for this pump consists of two identical seal
assemblies installed back-to-back in tandem. The
two seals are provided for repair under one part
number for the mechanical seal kit.
Before attempting to remove the seal, remove the
oil cavity drain screw and O-ring (34 and 5H) and
drain the oil from the seal cavity.
Disengage the machine screws (38) and use a pair
of flat head screwdrivers to pry the oil chamber
cover (37) and oil seal (35) off the shaft as a unit.
Use caution when removing the oil chamber cover;
the lower seal stationary element and seat will also
come off the shaft. Remove the oil chamber gasket
(5J).
Invert the oil chamber cover and remove the lower
seal stationary element and seat from the cover.
With the oil chamber cover inverted, press the oil
seal (35) out of the oil chamber cover from the back
side.
Lubricate the seal area of the rotor shaft, and slide
the rotating portion of both the lower and upper
seal assemblies off the shaft.
To remove the stationary portion of the upper seal
assembly, slide two stiff wires with hooked ends
along the shaft and hook the stationary seat and
element from the back side. Pull the stationary por-
tion of the seal from the bore of the oil chamber (6).
Stuff a clean tissue into the stationary seal seat
bore or wrap a small rag around the shaft to pre-
vent contamination of the motor cavity.
If no further disassembly is required, proceed with
the appropriate
PUMP END REASSEMBLY
proce-
dures for your specific pump.
Complete disassembly procedures for the pump
motor
are not
included in this manual. Instructions
are provided only for replacement of the pump end
components, the power cable and capacitor. If the
pump fails to run and motor problems are sus-
pected, contact your Gorman-Rupp distributor or
the factory for motor service.
POWER CABLE AND CAPACITOR
REPLACEMENT
(Figures 1 And 2)
Power Cable Removal
With the strainer (39) and suction cover (1) re-
moved, disengage the hardware (16 and 17) and
remove the discharge nipple (15) and loose parts
of the flange assembly (14).
Disengage the hardware (20 and 21) and remove
the handle (19).
Disengage the hardware (24 and 25) and separate
the power cable clip (31) from the outer pump cas-
ing (31).
Remove the hardware (23) securing the cable
gland to the pump casing. Pull the outer pump cas-
ing up off the motor, feeding the cable gland down
through the hole in the casing as the casing is re-
moved.
Remove the holding rods and lockwashers (10 and
11) securing the motor top cover (12) to the upper
motor cover (29).
Raise the motor top cover to expose the power
cable leads and capacitor (13). Remove the con-
nectors (18) from the power cable leads and re-
move the power cable and inner power cable
gland gasket (5E).
It is not necessary to remove the ground wire (28)
unless replacement is required. To remove the
ground wire, disengage the machine screw (27).
If the capacitor (13) requires replacement, remove
the shrink tubing (not shown) and separate the ca-
pacitor leads from the stator leads.
Use a pair of pliers to remove the grommet (5) from
the upper motor cover (29). Use caution not to al-
low the motor leads for the capacitor to slip down
into the motor.
