Bad Harmonic Balancer: Signs to Watch Out For
- 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.
How does a crankshaft damper work?
The circular device, made of rubber and metal, is bolted at the front end of the crankshaft to help absorb vibrations. The rubber inside the pulley is what actually absorbs the vibrations and keeps them at a safe level. In essence, the device is designed to help prevent crankshaft failure.
How is a harmonic damper used in a crankshaft?
Countering torsional crank motion and harmonic vibration. The harmonic balancer helps minimize torsional crankshaft harmonics and resonance. The damper is composed of two elements: an inertia mass and an energy dissipating element. Most often made of rubber, this element may be composed of a synthetic elastomer, a clutch, a spring or fluid.
What kind of damper is used on cast iron engine?
Over the years many of these engines use solid cast iron or aluminum crank pulley or audible NVH damper (reducing engine noise heard in the occupant compartment). Audible NVH has been the biggest factor in OE manufacturer decisions throughout the vehicle.
When do you need a harmonic damper for a V8 engine?
An interference fit ensures the device moves in perfect step with crankshaft. It is essential on engines with long crankshafts (such as straight-6, straight-8 engines) and V8 engines with cross plane cranks, or V6 and Straight-three engines with uneven firing order.
How does the ATI Super damper protect the crankshaft?
Viscous dampers are effective across a broad frequency range to protect against the crank-destroying and secondary harmonic effect. The ATI Super Damper uses two concentric rings – an inner one to connect to the crankshaft directly, and an outer one, with weight and diameter designed to counteract the torsional vibrations of the crank.
