What are the symptoms of a bad harmonic balancer?
What are the symptoms of a bad harmonic balancer?
- Cracked, bulging or missing rubber.
- Harmonic balancer wobbles.
- Separatation between the hub and outer ring.
- Timing marks slipped. Timing error code or mis-fire.
- Excessive wear on main bearings.
- Oil pump failure.

- Loosening or broken bolts.
How to identify a failing harmonic balancer?
harmonic balancers keep failing
- Heat stress
- Road salt
- Ozone attacking the rubber components of the balancer
- Stress from integrated drive pulleys
- Loads from other devices (powers steering pump, air conditioning compressor, alternator, air pump, water pump
- Road debris inflicted damage
- Crankshaft failure (broken or cracked)
How to troubleshoot a harmonic balancer?
How to Troubleshoot a Harmonic Balancer
- Loosen the lug nuts on the driver-side wheel by turning them 45 degrees counterclockwise with a tire wrench.
- Raise the front of the vehicle onto jack stands. ...
- Finish removing the lug nuts and pull the wheel off the wheel hub assembly.
How do you know if your harmonic balancer is bad?
10 Signs The Harmonic Dampener Has Failed or is Close to Failing
- Incorrect timing marks If the outer ring has separated from the inner ring, the timing marks will move. ...
- Worn edges on the belt The outer ring can move so much that the grooves are no longer aligned with the rest of the accessories’ pulleys. ...
- Engine vibration If you have an odd engine vibration and no misfire codes, check the dampener for damage.
What are the symptoms of a bad harmonic balancer?
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.Sep 16, 2020
Can u drive with a bad harmonic balancer?
It's not okay to drive with a bad harmonic balancer. The bouncing crankshaft will wear on the main bearings. It can also tear up drive belts and possibly come apart posing a danger to people and property.Jun 9, 2020
Can a car run 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.Jul 28, 1999
Can a bad harmonic balancer cause engine vibration?
Engine vibration 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.Jan 8, 2016
How much does it cost to fix a harmonic balancer?
How much does a harmonic balancer usually cost? A harmonic balancer replacement can be as low as $150 to over $550.
Does harmonic balancer affect timing?
Does Harmonic Balancer Affect Timing? A potential problem with the harmonic balancer is misalignment of timing marks. The timing marks can shift if the layers are separated or slip. The timing light will be out, which will make it difficult to time the engine properly.Dec 2, 2021
Can you repair a harmonic balancer?
The good news is, the harmonic balancer can easily be repaired with a kit that usually retails for under $10.Oct 10, 2017
What would cause a harmonic balancer to break?
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.Jan 14, 2016
There Are Basically, Two Types of Harmonic Balancers
What Is The Most Common, Harmonic Balancer Failure
- The rubber isolation ring deteriorates completely. As a result, the pulley completely dislodges, from the center portion of the balancer.
Heat, Seems to Be The Biggest Cause of Failures
- The constant twist/untwist movement, causes the rubber to heat. The most damaging cause, would be engine overheating. That extra heat can dramatically accelerate, deterioration of the rubber isolation ring. In addition to heat deterioration; fluid contamination can also, accelerate decomposition of the rubber isolation ring. The oil and coolant contamination; softens the rubbe…
Conclusion
- So, a simple way to think of the harmonic balancer is like a, massive stress reliever. Because, it absorbs the violent torsion of the modern-day engine. Thank You !
