What happens when harmonic balancer fails?
Although the harmonic balancer may seem simple enough, if it fails, it can cause major problems. Without the balancer dampening unwanted crankshaft vibrations, engine failures, such as worn rod bearings and a broken crankshaft, may result. A faulty balancer can damage the belt and engine-driven accessories as well.
How long does harmonic balancer last?
On certain engines, sometimes these last forever, last the life of the engine. And certain engines they might only last 50,000 miles or less than 10 years.
Can you drive with a bad harmonic balancer?
With the harmonic balancer no longer working the crankshaft will bounce on the main bearings which cause wear and damage as you drive. It can also even tear up drive belts and come apart entirely which creates a serious safety risk to your surroundings as your vehicle moves.
What causes crankshaft pulley failure?
All components come with a recommended torque, this should be checked before the parts are tightened. Similarly, if the belt tension is too strong or the auxiliary equipment has failed the pulley will also fail. The cause is linked to the coupling having made contact with the flywheel rim.
Can you start a car 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.
Can a harmonic balancer be repaired?
The good news is, the harmonic balancer can easily be repaired with a kit that usually retails for under $10.

How do you know if you need a new harmonic balancer?
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.
What does it cost to replace harmonic balancer?
How critical is the harmonic balancer?
A harmonic balancer sounds like a crucial part on a spaceship in some pulpy 1950s sci-fi story, or something you need so you can play music with hobos when you’re ridin’ the rails. However, it’s actually an important part on your engine that helps your crankshaft last as long as possible.
Is a harmonic balancer the same as a harmonic damper?
A harmonic balancer (sometimes called crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly.
Can harmonic balancer be repaired?
How do I know when to change my harmonic balancer?
Signs that your crankshaft harmonic balancer needs to be replaced include:
- The engine is loud and you feel vibrations coming from your engine.
- The pulley belt may slip causing your vehicle to backfire or misfire.
- The vehicle’s ignition timing will be off.
- The vehicle will not start at all.
Can a faulty harmonic balancer cause a crankshaft 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.

What does the harmonic balancer do in an engine?
Harmonic balancers are misnamed. They do not balance an engine, rather they absorb and remove unwanted vibration due to torsional twisting of the crankshaft. They are in effect vibration dampeners and are frequently called dampeners.
