Abstract
An engine assembly includes an engine structure, a camshaft supported on the engine structure, a first cam phaser coupled to a first axial end of the camshaft, and a locating pin. The camshaft includes a first shaft, a second shaft, a first cam lobe and a second cam lobe. The first shaft defines a first opening. The second shaft is supported within the first shaft and defines a second opening. The first cam lobe is located on and fixed for rotation with the first shaft. The second cam lobe may be located on the first shaft and fixed for rotation with the second shaft. During assembly, the first cam phaser is located on the camshaft and the locating pin may be inserted through the first and second openings to rotationally fix the first and second shafts. The first cam phaser is then secured to the camshaft.
