To eliminate the necessity of having to
remove and replace the nylon/glass filled
pulley when installing a replacement
motor, the complete motor/pulley and
plate assembly will be serviced (as
shown in the illustration) ready to be
mounted to the base. However, should a
nylon/glass filled pulley become dam-
aged in the field, a service replacement
pulley is available. The pulley can be
removed and replaced as follows:
REMOVAL: It is necessary to use a puller
with at least a three (3) inch spread.

1. Remove the shaft cover at the rear of
the motor and "backup" the end of
the motor shaft with a socket. This
will prevent internal damage to the
motor when tapping on the opposite
end of the shaft during pulley instal-
lation.
2. With the hub fingers out, position
the pulley over the motor shaft until
the splines begin to mesh.
3. Place a 1/2 inch 1.0. deep socket,
pipe, etc., over the hub fingers and
gently tap the pulley over the
splines until it bottoms out on the
shaft shoulder.
NOTE: When the pulley has been prop-
erly positioned against the shaft shoul-
der, the hub fingers
at
the pulley front
should be located in the shaft groove.
4. Replace the shaft cover at the rear of
the motor and reinstall.
MOTOR CIRCUIT TESTING
The motor overload protector, motor
starting switch and the motor are the
three components that should be tested if
the motor assembly is suspected of being
the cause of a service problem. The
power cord should be unplugged and all
wiring connections from the machine
wiring harness to the motor starting
switch should be disconnected before
any testing is done to the motor.
Overload Protector
The overload protector is built into the
motor and is not serviceable. The con-
tacts of the overload protector are nor-
mally closed and open in response to a
temperature rise, an excessive amperage
draw or a combination of both. The
contacts reset automatically when they
cool off. All automatic washers are
