MAINTENANCE AND REPAIR
2. Install the cable inlets (236) and clamps (238)
on the cables (234). Install new rubber seals
(235); locate the new seals above the deforma
tion mark left on the cables by the old seals.
3. Cut the motor cables (234) above the seal de
formation marks. Strip the cable's outer insula
tion so that the individual leads are long enough
to make motor connections; the ground leads
must be longer than the others.
4. Install new ends and ground connectors on the
new leads. Remove the identification sleeves
from the old leads, and install on the new wire
ends. Install identifying sleeves or markers
identical to those on the old leads on the new
leads.
5. Lubricate the outside of the cables, and pull the
rubber seals (235) down to within two inches
(51 mm) of the end of the cable sheaths. Pull the
cable inlets (236) down the cables until flush
with the rubber seals.
6. Insert the cable leads into the motor cover
(230), making certain that the rubber seals bot
tom in the cover, and that the cable inlets (236)
seat flush against the seals. Secure the cable
inlets and installed components with the
screws (237).
7. Install the cable clamps (238), and secure with
the screws (239).
8. Install the insulation sleeves (414) in the upper
bearing cover (222). Thread the leads from the
stator (301) through the insulation sleeves, and
seat the upper bearing cover in the motor hous
ing (302).
Refer to the wiring diagrams in INSTAL
LATION, Section B, when connecting all
motor leads. Misconnected leads could
severely damage the motor, and cause
injury or death to personnel.
9. Connect the leads from the motor and control
cables, and from the stator (301), to the terminal
boards (226).
10.Secure the ground connectors with the screws
and washers (228 and 229).

FIGURE E-3. Moisture Switch Check
11.The moisture switch (224) should be checked
and, if required, adjusted any time the motor is
opened for service.
The switch is extremely sensitive to atmo
spheric moisture and contamination from
handling; therefore,
make sure
hands are
clean and dry before touching the switch.
When installing a replacement switch, re
move it from the air‐tight plastic shipping
bag prior to installation to allow it to accli
mate to local humidity levels
before
check
ing and adjusting the clearance as follows.
See FIGURE E-4, and install the switch in a simple
bell circuit or other test circuit. Use a feeler gauge
to check clearance between the expander and
switch body; clearance should be 0.100 inch (2,5
mm).
