A power actuator assembly includes a torque transmission device, a motor mounted to the torque transmission device extending along a motor axis, and a screw coupled to the torque transmission device and extending along a screw axis. An adjustment mechanism interconnects the screw and the torque transmission device and permits selective rotational adjustment between the adjustment mechanism and the torque transmission device to rotate the motor relative to the torque transmission device. A connecting device releasably interconnects the adjustment mechanism to the torque transmission device to permit repeated re-positioning of the motor relative to the torque transmission device.

A worm/worm gear assembly comprises a worm having teeth defined by at least one thread disposed thereon and a worm gear having teeth protruding from a surface thereof. At least one of the worm and the worm gear is fabricated from a resilient material. The teeth of the worm and the teeth of the worm gear are interengaged and in a compressive relationship with each other to maintain double flank contact therebetween. At low- or no-load conditions, the double flank contact is made at the opposing outer edges of each of the teeth. At moderate-load conditions, the contact extends from the opposing outer edges of each of the teeth toward the center of each of the teeth. A method for delashing a gear system comprises disposing the worm in mechanical communication with the worm gear and loading the worm gear to cause the worm gear to compressively engage the worm.
