diate (48) so that the lower bearing (31) seats
squarely in the intermediate bearing bore.
Secure the gasket (14) to the cap with a light coat­
ing of gasket adhesive.
Position the intermediate over the bearing and
align the mounting holes with those in the bearing
cap. Apply `Never‐Seez' or equivalent compound
to the threads of the capscrews (12). Install the
capscrews and lockwashers (13); torque the caps­
crews evenly in a cross‐sequence to 20 ft. lbs. (240
in. lbs. or 2,8 m. kg.).
Motor Housing And Intermediate Reassembly
(Figure E-1)
Use fresh solvent to clean the bores and all gasket
surfaces of the motor housing (18), 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 (15, 16
and 43). Position the gaskets on the motor hous­
ing, making sure the gaskets are properly seated
and the adhesive holds them securely.
Install a three‐leg sling in the intermediate flange
holes and lower the assembled intermediate and
rotor assembly into the motor housing. Use cau­
tion to guide the upper bearing 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 (44). Secure
the intermediate to the motor housing with the
hardware (45 and 46); torque the nuts evenly in a
cross sequence to 120 ft. lbs. (1440 in. lbs. or 16,6
m. kg.).
Refer to PUMP END REASSEMBLY, and reas­
semble the pump end components.
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.
(Figure E-2)
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, gland bushing and terminal housing onto
the cable, allowing approximately 3 ft. (1 m) of ca­
ble to extend beyond the terminal housing. Tempo­
rarily tape the green and yellow ground wires to the
cable.
