MAINTENANCE AND REPAIR PAGE E - 16
With the motor housing and stator positioned up­
side down, carefully lower the assembled inter­
mediate, rotor shaft and bearings into the motor
housing until the female terminal (14) can be se­
curely attached to the male terminal (15) on the
moisture sensor.
Position the intermediate so the holes for the
mounting hardware in the intermediate align with
those in the motor housing and press the inter­
mediate into the motor housing until fully seated.
Apply “Never‐Seez” or equivalent compound on
the threads of the capscrews (12) and secure the
intermediate to the motor housing with the hard­
ware (11 and 12). Torque the capscrews to 28 ft.
lbs. (327 in. lbs. or 3,8 m. kg.).
Terminal Housing Assembly Installation
(Figure E-1)
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 po­
sition and locked out, or that the power
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 to make
electrical connections.
Secure the pump in upright position with the hoist­
ing bail and terminal housing assembly removed.
Clean the area round the motor housing opening
with fresh cleaning solvent, being carful not to al­
low any dirt, debris or cleaning solvent to enter the
motor housing.
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.
Make sure that the terminal housing O‐ring sup­
plied with the replacement terminal housing as­
sembly is securely installed on the shoulder of the
terminal housing and that it is clean and undam­
aged. Check to ensure that the power and control
cable ground leads are securely attached to the in­
side of the terminal housing body.
Make sure the contacts on the ends of the power
and control cable leads are firmly installed in their
respective housings and position the terminal
housing over the opening in the top of the motor
housing.
Check to ensure that the contacts on the ends of
the motor stator leads are firmly installed in their re­
spective housings. Check to ensure that any wire
connectors installed on the stator leads are tight
and secured with heat shrink tubing.
The plastic housings on the ends of the power and
control cable leads are color‐coded to match the
housings on the leads coming off the stator. Match
each cable lead housing with its corresponding
stator lead housing and firmly press them together
until they lock in place.
When all of the cable lead housings are securely
locked into the stator lead housings, slide the ter­
minal housing assembly down over the studs in the
top of the motor housing. Secure the terminal
housing to the motor housing by tightening the
hardware (8 and 11) in an alternating pattern until
the terminal housing is fully seated in the motor
housing. Torque the hex nuts (11) to 27 ft. lbs. (3,7
m. kg.).
After installing the motor housing, perform the vac­
uum check described below to ensure the water‐
tight integrity of the pump.
Reconnect the power and control cable leads to
the control box. Check pump rotation as described
in OPERATION, Section C, before putting the
pump back into service.
