The gear assembly is contained in a housing assembly and includes a first gear rotatably mounted to the housing and having connecting means to the motor output shaft. The first gear has end journals and a worm disposed therebetween. A second gear is carried for rotation on the lead screw and is in meshing engagement with the first gear. The housing assembly includes adjustable supporting means for supporting an end journal. The adjustable supporting means includes an adjustable set bearing that is threadably insertable into an access port into contact with an end journal. The adjustable set bearing has an inner smooth concentric surface for supporting an end journal of the worm and allowing rotatable movement of the end journal. An outer surface of the adjustable set bearing is threaded while an inner cylindrical access port is also threaded for selectable adjustment of the set bearing within the access port.
