Camshaft

DESCRIPTION
The nodular iron camshaft is mounted in the engine block and supported with four steel backed Babbitt bearings. A thrust plate, located in front of the first bearing, is bolted to the block and controls the camshaft end play.

OPERATION
The camshaft is driven by the crankshaft through a timing chain and sprockets. The camshaft has precisely machined (egg-shaped) lobes to provide accurate valve timing and duration.
