The timing drive system has been designed to provide quiet performance and reliability to support a NON free-
wheeling engine. 

The timing drive components include a crankshaft sprocket (4), camshaft sprockets, tensioner pulley, hydraulic 
tensioner and a timing belt (3). The water pump (2) is driven by the back side of the timing belt (3). The right 
and left camshaft sprockets are keyed and not interchangeable because of the cam sensor pick-up wheel on the 
left sprocket. See Fig. 295.
