Abstract
An engine assembly may include a camshaft rotationally supported on an engine structure. The camshaft may include a first shaft, a second shaft located in and rotatable relative to the first shaft and a partial cam lobe located on the first shaft. The partial cam lobe may include a peak region and may define a partial bore. A radial distance defined by the partial bore between first and second circumferential ends of the partial bore may be greater than or equal to a radial width of the first shaft. The partial cam lobe may define a recess extending in a radial direction through the partial bore and into the partial cam lobe. The camshaft may include a sleeve located within a radial passage defined by the second shaft and the recess in the partial cam lobe and radially locating the partial cam lobe relative to the second shaft.
