Camshaft

DESCRIPTION
Two overhead camshafts provide valve actuation, one front (radiator side of cylinder bank) and one rear (Fig. 5). The front camshaft is provided with a distributor drive and is longer. Both camshafts are supported by four bearing journals, thrust for the front camshaft is taken at journal two and the rear at journal three. Front and rear camshaft driving sprockets are interchangeable.

OPERATION
The camshafts are driven by the crankshaft via drive sprockets and a belt. The camshafts have precisely machined lobes to provide accurate valve timing and duration.
