Abstract
An engine camshaft drive includes timing belt pulleys which are angularly adjustable on their respective camshafts to provide manual adjustment of the engine valve timing. The arrangement features combination securing and adjusting means in the form of a threaded stud having an eccentric body portion intermediate its ends that coacts with a radially elongated opening in its associated drive sprocket to provide angular adjustment of the sprocket on the camshaft, while the stud also provides means for securing the drive sprocket to the camshaft when the adjustment has been completed.
