Elevation Motor Replacement
Replacement the Elevation Motor
1. Position the elevation motor in its mount. Be sure to hold the motor’s electrical
cable closely against the motor to prevent its being pinched between the motor and
the treadmill frame.
2. Replace and tighten the four screws that hold the elevation motor to the motor
plate. Use a 9/64-inch Allen wrench.
3. Connect the motor cable connector to the connector J5 on the Motor Control Board.
4. At the bottom of the motor plate, replace the drive pulley on the motor shaft.
5. Check vertical alignment of the drive pulley, idler pulley, and right hand elevation
screw bearing. To do this, rest a straightedge on the pulley and the bearing faces,
then position the drive pulley on the shaft until alignment is achieved. See Diagram
