Abstract: A fuel pump drive gear assembly is provided which includes torsional absorption elements positioned between a drive gear and a fuel pump hub. The drive gear includes a plurality of apertures for receiving a plurality of projections formed on the fuel pump hub. The torsional absorption elements are positioned in the apertures between the projections and the drive gear so as to frictionally engage a surface of both the projection and the drive gear, thus creating a mechanical driving connection between the rotating drive gear and the fuel pump hub. The torsional absorption elements have adequate stiffness to provide the necessary torque to drive the fuel pump, while retaining sufficient flexibility to permit relative rotational movement between the driving gear and the fuel pump hub for absorbing the vibratory loads imposed upon the gear assembly by the fuel pump without compromising the timing between the fuel pump and engine.

Abstract: A deflectable trunnion assembly that has a deflectable eye member or hook. The trunnion assembly is connectable to a pulley block of a hoist. The trunnion assembly has a trunnion block on which a deflectable spherical roller thrust bearing rides. The eye member rides on the spherical roller thrust bearing. The trunnion block is covered by a cover that contains a dome. The eye member ends in a pin that has a balled end. The balled end of the pin rotates within the dome, during deflection within the spherical roller thrust bearing of the trunnion assembly.

Abstract: A unitized portable hoist having a base structure. A support structure is attached to the base structure. A hoist drum is rotatable attached to hydraulic motors which are in turn attached to the base structure. A crown block is attached to the base structure below the hoist drum. An electric motor drives a hydraulic pump, both of which are attached to the base structure. The hydraulic pump drives the hydraulic motors. A cable is taken up and let out by the hoist drum. A fall block rides on the cable.
