Camshaft

Fig. 4

DESCRIPTION
Two overhead camshafts provide valve actuation, one left (front cylinder bank) and one right (rear cylinder bank) (Fig. 4). The distributor is directly driven by the right camshaft. Both camshafts are supported by four bearing journals integral with the cylinder head. A flange at the rear of the camshaft acts as a thrust collar. Right and left 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.
