Procedure 6.3 - Replacing the Lift Motor, Rotation Sensor or
Magnet Hub (1L Units)
Remove the magnet hub and rotation sensor bracket from the defective lift motor and mount
them on the new lift motor. Unless the magnet and/or rotation sensor are defective, do not
remove them from their mounting positions on the magnet hub and sensor bracket.
WARNING
Always turn off the circuit breaker and unplug the treadmill before you remove the treadmill hood.
Removing the Lift Motor
1. Remove the hood.
2. Remove the red lift motor lead from the lift motor capacitor, but leave the remaining red wire
connected to the terminal.
3. Remove the black lift motor lead from the lift motor capacitor, but leave the remaining black
wire connected to the terminal.
4. Disconnect the connector on the white lift motor lead.
Note:
Do not disconnect J3 from the lower PCA. The connector disconnected in the previous step
connects the white lift motor lead to J3.
5. Disconnect the molex connector on the rotation sensor wire assembly from connector J2 on
the lower PCA.
Note:
When the rotation sensor wire assembly is disconnected from the lower PCA, the zero sense
switch must be disconnected as well.
6. Disconnect the two blue wires on the rotation sensor wire assembly from the zero sense
switch terminals.
7. Place the treadmill on its left side.
8. Remove the two shoulder screws and nuts that secure the lift motor to the treadmill frame
(see Diagram 6.3). Remove the lift motor and set it aside.
9. Remove the set screw that secures the magnet hub to the lift motor. Set aside the magnet
hub.
