How To... Replace the Drive Motor
Special Service Tools Required: NONE
Note: The Drive Motor weighs approximately 50lbs. It is
also in close proximity to other components. Therefore,
care should be taken when lifting out the Motor not to
injure yourself or bang the Motor up against these
components.
1. Turn the unit power OFF at the switch, and then
unplug the line cord at the wall outlet.
2. Remove the inside Upright Covers, the Front Cover,
and the Motor Cover. See “How to…” in this
section.
3. Disconnect two Cable Connectors from the Motor,
or disconnect the 3-Pin and 5-Pin Connectors
between the Motor and Motor Controller.
4. Loosen the tension on the Drive Motor Belt by
inserting a flat blade screwdriver into the slotted end
of the Idler Arm. Raise the Idler Arm just enough to
install an Allen wrench into the Access Hole of the
Idler Arm to keep it in a raised position.
CAUTION: DUE TO EXTREME
SPRING TENSION, DO NOT RAISE
THE IDLER ARM ANY HIGHER THAN
NECESSARY.
5. Remove the four Lock Nuts, Flat
Washers, and Insulating Washers
from the Motor Studs.
Note: The Motor weighs close to 50 lbs.
Before proceeding to the next step,
make certain that this weight can be
handled.
6. Initially lift the Motor off its studs.
Then move the Drive Motor in
towards the Left Side of the Frame
to allow added clearance between
the Pulley and Lift Motor. Then tilt
the Pulley end up first, and continue
to lift out the Motor at this angle.
Once the motor is out, remove the
Insulating Pad under the Motor
Plate.
Note: Illustration shown, is without a
number of drive and unit components
for clarity purposes.
