Procedure 6.5 - Replacing Drive Motor
1. Set the treadmill’s on/off switch in the “off” position and remove the treadmill’s power cord
from the AC outlet.
2. Remove the treadmill’s hood.
3. The drive motor and flywheel are balanced as a matched pair. Since the flywheel is
balanced to a specific motor, flywheels should not be removed from one motor and installed
on a different motor. If the drive motor is replaced, the drive motor and flywheel should be
replaced as a unit.
4. Disconnect the red and black drive motor wires from the lower PCA and green-yellow wire
from its frame ground.
