Abstract
A two-piece sheave assembly is provided for a tire lift/carrier winch. The sheave assembly includes a molded plastic, one-piece sheave component that is molded to include a first sheave side plate, an integral sheave center hub with a cable-wrapping track thereon and optionally an integral annular toothed driven ring gear for mating with a toothed drive gear of the winch. The molded plastic sheave component is attached to a second sheave side plate, which may be metal, to form the two-piece sheave assembly. Apertures for the winch drive shaft and the pivotable cable end fitting are integrally molded in the first sheave component.
