Camshaft

DESCRIPTION





Fig. 6

Both nodular iron camshafts have six bearing journal surfaces and two cam lobes per cylinder (Fig. 6). Flanges at the rear journals control camshaft end play. Provision for a cam position sensor is located on the intake camshaft on the rear of the cylinder head. A hydrodynamic oil seal is used for oil control at the front of the camshaft.

OPERATION
The camshaft is driven by the crankshaft via drive sprockets and belt. The camshaft has precisely machined lobes to provide accurate valve timing and duration.
