The Harmonic Balancer is a device located in front of the crankshaft of an internal combustion engine. When the cylinder fires, force is applied to the crankshaft that causes it to twist and vibrate. This creates stress which the crankshaft can't withstand, resulting in its failure. The harmonic balancer is installed to prevent the failure of the crankshaft. Its purpose is to absorb the vibrations produced in the shaft.
The harmonic balancer is a pulley-like device made of two cast-iron components connected by a rubber ring. The rubber ring absorbs vibrations in the crankshaft produced by the movement of the piston. It is also called a damper. The heavy mass of the device helps to maintain the stability of the moving parts in the engine. If you encounter any difference in the performance of your car's harmonic balancer, you should replace it as soon as possible to avoid engine damage. The Used Part stocks a wide range of harmonic balancer replacements for every car make and model.
