Camshaft Transmission
The timing belt that drives both camshafts and the coolant pump is a conventional single-tooth belt. The camshafts' belt pulleys are secured with three screws in each camshaft. The holes for the screws are oval to enable correct setting of the camshafts' position. Tensioning of the timing belt is obtained using a mechanical belt tensioner. The belt tensioner presses on the belt via a tensioner roller mounted on a lever. The idler roller on the belt's other side prevents the belt from starting to vibrate.
