Abstract: Apparatus for permitting selective adjustment of the angular position of a sprocket or gear relative to a driven shaft for changing the timing of an internal combustion engine includes a circular sprocket carried on an end face of the cam shaft in axial alignment with the shaft's axis of rotation. A first pin extends from the end face parallel to the axis of rotation at a location radially outwardly thereof through an enlarged opening in the sprocket. An adjusting plate is engaged with the sprocket on the side opposite the end face. The adjusting plate is positively engaged with the first pin with a second pin extending between the adjusting plate and the sprocket parallel to the axis of rotation but at a radial location different than the first pin such that angular adjustment of the adjusting plate about the axis of the first pin produces angular adjustment of the sprocket relative to the axis of rotation of the shaft.
