Definition: Cranching, also known as "crankshaft" or "crank", is a mechanical part of an internal combustion engine that rotates on its own axis and provides the driving force for the crankshaft. It's typically made out of steel or aluminum and has a flat top with a series of gears at each end that rotate in opposite directions to drive the engine. The cranking mechanism is responsible for turning the cylinder head, which is connected to the cylinders through the pistons and connecting rods
