This is where the harmonic balancer comes into play. The piston transfers that force onto the crankshaft and as this happens it can generate a rotate and return motion through the crankshaft. When an engine cylinder fires, there is force applied to the piston. In a majority of vehicles, it is also used as a pulley for drive belts which power other accessories on the engine, such as the alternator, power steering and air conditioning. Its job is to reduce vibration in your engine.
