Crankshaft
A precision machined part that channels the power produced by the pistons. The crankshaft converts the power from the pistons into rotary motion.
The crankshaft consists of the following elements:
Crankshaft main journals: Polished surfaces that fit into the main bearings of the engine block.
Crankshaft rod journals: Polished surfaces that are offset from the main journals. The connecting rods are bolted to the rod journals.
Counterweights: The crankshaft has a series of counterweights which prevent vibration
Crankshaft flange: A surface where the flywheel is bolted.
Crankshaft snout: A narrow protrusion that fits through the front of the engine block.
