Abstract: An improved springless engine compensator comprising a first load bearing flange, a compensator bushing member, an output ring member threadably mounted on the compensator bushing member, a second load bearing flange. The flanges and the compensator bushing are fixedly mounted to an input shaft. The output ring member is mounted between the flanges for limited axial and rotational movement relative to the input shaft. The compensator absorbs rotational shock loads while transferring rotational loads from an input shaft to the output ring member. Compensating rotation is easily and precisely adjustable with the use of shims. Uniquely, the output ring member simultaneously compensatingly rotates and moves; axially on the compensator bushing member, and is captively restrained by the bearing flanges. Buffer members can be provided if desired between the mating faces of the flanges and the output ring member.
