ABSTRACT:
A selectively engageable motor-drive assembly operable for moving a vehicle door or ramp to enable manual operation or motorized operation is provided, having a motor, a pulley drawing a cable attached to the door or ramp, a torque-multiplying arrangement positionable between a fully-engaged position and a partially-disengaged position, and an actuator mechanism for positioning the torque-multiplying arrangement in accordance with a selection of manual or motorized operation. The actuator mechanism may be actuated by a solenoid that is activated by an operator through a control unit. Also, a cam may be provided to define the movement of the actuator mechanism.
