About the Crankshaft

The crankshaft, commonly called the "crank," is arguably the most important part of the engine. It's located towards the lower end, and is positioned horizontally. Its rotation governs essential parts, such as the water and oil pumps, the pistons, and the camshaft(s). The timing gears, more often a belt or chain, are what connect and synchronize the camshaft and crank. This is an essential connection because without the unison between the camshaft and the crankshaft, the engine wouldn't be capable of running. This is why there is often a timing cover protecting the belt, chain, or gears from debris and gravel. The functioning of the main parts are connected and unified at the crankshaft. At either end of the crankshaft, there are main bearing shells, which allow it to rotate staunchly in place.
