Procedure: Lift motor shroud
The drive motor is located below the plastic shroud at the front of the treadmill. To remove
the shroud at access the motor, proceed as follows:
1. Remove the Philips-head screw at the center of the front edge of the shroud.
2. Lift up the front of the shroud, lifting from both sides to separate the Velcro strips.
3. Lift the shroud up the vertical rails as far as it can go, then suspend it using a bungee
cord looped over the gooseneck rail and hooked up under the upper edge of the shroud.
Tip the Treadmill on its side
Lift either side of the treadmill and tip the treadmill on its side. This makes accessible both
the elevation motor and the belt drive train below the motor plate.
Remove the Elevation Motor
1. Using pliers, remove the end cap (tap nuts) from both ends of the wheel axle at the front
end of the treadmill.
2. Remove the wheels and the bushings from both ends of the axle, then remove the axle
from the treadmill.
3. At the bottom of the motor plate, loosen the idler pulley-mounting nut using a 17-mm
socket wrench. See Diagram A.
