What Does a Harmonic Balancer do? As the name suggests Harmonic Balancer has nothing to do with balancing an engine, it absorbs unwanted vibration generated from twist and turn of the crankshaft. Harmonic balancers are highly useful to smooth up vibration dampeners; therefore, its other name is dampeners.
Torsional vibration is the outcome of firing pulses of combustion events. For particular frequencies, the cranking sound might resonate, creating a vibrant and loud vibration. With the help of cylinder firing, the forces are moving to and fro, here, harmonic dampener is essential to run the move continuously. For its constant and smooth functionality, a damaged harmonic balancer needs to be removed before it stops functioning.
