CAMSHAFT
DESCRIPTION
The induction-hardened, forged-steel camshafts are hollow to minimize weight. The camshaft and crankshaft
sprocket teeth are rubber coated, making chain noise indiscernible from other engine noise.
OPERATION
The camshaft is driven by the crankshaft via drive sprockets and a chain. The camshaft has precisely machined
lobes to provide accurate valve timing and duration.
