Why is my car pulley making noise?
Why is my car pulley making noise?
Idler pulley slippage is likely to follow after it becomes worn out enough. This will cause the pulley to bind and then rub against the engine belt. As a result, there will be squealing noises coming from the engine area that will only get worse until the pulley is replaced.
How much does it cost to replace a crankshaft damper?
The average cost for crankshaft damper replacement is between $364 and $402. Labor costs are estimated between $124 and $157 while parts are priced between $239 and $245. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.
How do I know if my vibration damper is bad?
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.
What does a damper pulley do?
A damper pulley, commonly known as a crankshaft pulley, is a pulley mounted at the front end of the crankshaft. It drives the acces- sory belts, which in turn drive the alternator, air conditioning compressor, power steering pump, water pump etc.
What causes a harmonic balancer to go bad?
Over time, the crankshaft harmonic balancer can go bad from constant exposure to chemicals, the elements, or from old age. If this happens, the crankshaft may develop cracks and ultimately fail.
What is a crankshaft damper?
A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be interference fit to the crankshaft in order to operate in an effective manner.
What are the symptoms of a bad harmonic balancer?
If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
What does a vibration damper do on an engine?
The damper is designed to absorb torsional and vertical vibrations from the crank, as a result of the engine combustion process.
Can you drive without a harmonic balancer?
The harmonic balancer is essentially part of the crankshaft pulley. And because the belts that go around the crankshaft pulley run all of the car’s accessories, without the harmonic balancer you’d have no air conditioning, no power steering, no alternator and no water pump.
