What are the symptoms of a bad harmonic balance?
The most common symptoms of a bad harmonic balancer include:
- Engine Vibrations. The harmonic balancer’s job is to dampen vibrations applied to the crankshaft.
- Noticeable Harmonic Balancer Wobble.
- Unusual Noises.
- Illuminated Check Engine Light.
- Visible Wear or Damage.
What causes harmonic balancer failure?
If the rubber layer in the harmonic balancer dries or wears out, it can cause the entire harmonic balancer to completely fail by separating. If the harmonic balancer separates, the engine belts will usually come off and the vehicle will be left without engine accessories.
Can a harmonic balancer go bad?
Over time, the crankshaft harmonic balancer can go bad from constant exposure to chemicals, the elements, or from old age. Signs that your crankshaft harmonic balancer needs to be replaced include: The engine is loud and you feel vibrations coming from your engine.

Where is the harmonic balancer on a car?
Racing Technology A common part found on all high-performance engines is a harmonic damper (or harmonic balancer, as they are often called). Found at the front of the engine attached to the snout of the crankshaft, harmonic dampers are used to quell the harmonics of the crankshaft.
When do you need a harmonic balancer NHRA?
NHRA requires the use of an SFI 18.1 harmonic damper for any car running faster than 10.99 in the quarter-mile. Beyond that requirement, any engine that has been modified for increased horsepower and/or higher rpm limit can benefit from the use of a quality harmonic damper.”
What causes the seal on a harmonic balancer to loose?
Heat and engine vibration can cause the seal to become; hard and loose its sealing ability. As a result, allowing residual engine crankcase pressure; to force oil past the seal and out from the engine. Because the seal rides against the inner hub of the balancer; it can cause grooves in the seal surface.
