MAINTENANCE AND REPAIR
Rotor And Intermediate Installation
(Figure E-1)
Use
fresh
solvent to clean the bores and all gasket
surfaces of the motor housing (20), completely re
moving any old gasket and cement material. In
spect the sealing surfaces for burrs, nicks and pits
which could cause a poor seal, and repair or re
place as required.
Most cleaning solvents are toxic and
flammable. Use them only in a well ven
tilated area; free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain
ers.
Apply `3M Gasket Adhesive No. 847' or equivalent
compound to the motor housing gaskets (18, 19
and 42). Position the gaskets on the motor hous
ing, making sure the gaskets are properly seated
and the adhesive holds them securely.
Using a three‐leg sling and lifting eyes in the inter
mediate flange holes, carefully lower the as
sembled intermediate and rotor assembly (23) into
the motor housing (20), guiding the upper bearing
(24) into the motor housing bearing bore. Tap the
intermediate with a soft faced mallet until it mates
tightly with the motor housing.
Apply `Never‐Seez' or equivalent compound on the
threads of the motor housing studs (45). Secure
the intermediate to the motor housing with the
hardware (46 and 47); torque the nuts evenly in a
cross sequence to 120 ft. lbs. (1440 in. lbs. or 16,6
m. kg.).

Terminal Housing And Power Cable
Reassembly And Installation
(Figure E-2)
The electrical power used to operate
this pump is high enough to cause inju
ry or death. Make certain that the control
handle on the control box is in the OFF
position and locked out, or that the pow
er supply to the control box has been
otherwise cut off and locked out, before
attempting to open or service the pump
assembly. Tag electrical circuits to pre
vent accidental startup. Obtain the ser
vices of a qualified electrician, and refer
to the wiring diagram(s) in INSTALLA
TION, Section B, to make electrical con
nections.
Clean the exterior of the power cable with warm
water and mild detergent. Check for obvious physi
cal damage. Check the cable for continuity and in
sulation resistance (see
Electrical Testing
in
TROUBLESHOOTING
).
Do not
attempt repairs
except to cut off either end of the cable;
splicing is
not recommended
. Reinstall any wire tags or ter
minals which may have been removed.
Never attempt to alter the length or re
pair any power cable with a splice. The
pump motor and cable must be com
pletely waterproof. Injury or death may
result from alterations.
Use oil to lightly lubricate the outside of the pump
power cable (13), and the bores of the terminal
housing (16), terminal gland (12) and gland bush
ing (8) for ease of assembly. Slide the terminal
gland, cable grip (11), gland bushing, terminal
washer (7) and terminal housing on the cable, al
lowing approximately 3 ft. (0,9 m) of cable to ex
