ABSTRACT:
A barrel-type internal combustion engine includes a power output shaft assembly with a sliding joint. A power output shaft has a pair of spaced apart bearing surfaces and a plurality of radial splines between the bearing surfaces. A cam plate has a central hub and a cam track extending therefrom. The central hub has a longitudinal bore for receiving the shaft. The bore has a pair of spaced apart bearing surfaces and a plurality of radial splines between the bearing surfaces. When assembled, the power shaft is received in the bore of the hub, the bearing surfaces are generally aligned and the splines engage such that the shaft and cam plate are coupled for rotation about the rotational axis of the shaft and the cam plate is longitudinally slidable on the shaft.
