Every internal combustion engine contains a crankshaft. Since the pistons move in a linear direction, the crankshaft converts their movement into a rotational motion. This is necessary to keep the engine functioning properly.
A harmonic balancer is a special pulley mounted onto the very end of the crankshaft. It rotates the drive belts connected to the engine, which is how rotational energy is generated. Many different electrical components inside the car depend on the pulley for mechanical power, including the air conditioner compressor and the alternator.
In other words, the harmonic balancer ensures that mechanical power is evenly distributed to the most critical components of the vehicle. If you were to have a bad or malfunctioning harmonic balancer, it would cause your crankshaft to bounce. Energy problems and worn-out bearings would follow this symptom.
