What happens when the harmonic balancer goes bad?
What happens when the harmonic balancer goes bad?
The harmonic balancer is specifically designed to absorb harmonic engine vibrations as engine speeds rise. If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively.
What are the symptoms of a bad crankshaft harmonic balancer?
Symptoms of a Bad or Failing Crankshaft Harmonic Balancer. 1 1. Engine vibration. One of the first symptoms of a potential problem with the harmonic balancer is engine vibration. The harmonic balancer is 2 2. Misaligned timing marks. 3 3. Separated harmonic balancer.
What happens when a harmonic damper goes bad?
One automotive part that frequently gets overlooked is the harmonic balancer (also known as a vibration damper or crankshaft damper). Although the component is often forgotten, when it fails, it can cause major problems—including severe engine damage.
How are harmonic dampeners and balancers used in an engine?
Adding mass to the crankshaft assembly is one solution for minimizing vibrations in some engines, but this approach increases rotating mass of the crank and overall weight of the vehicle. The other cure is a crankshaft pulley with a harmonic dampener/balancer. A harmonic balancer is like a punching bag for the crankshaft.
The harmonic balancer is specifically designed to absorb harmonic engine vibrations as engine speeds rise. If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively.

How does a harmonic damper and balancer work?
“The harmonic balancer (damper) controls the twist to achieve durability and efficiency,” says LeBarron, who notes that not all dampers are constructed or function the same. “A dampener is like a rubber motor mount,” says Tom Lieb, founder and CEO of Scat Enterprises.
Where can I buy a harmonic balancer puller kit?
With the rattle gun the bolt came loose straight away. I had already purchased a harmonic balancer puller kit from super-cheap for $25, however had to buy three new bolts for it. The bolts provided in the kit had the wrong thread!
What causes a crankshaft harmonic balancer to fail?
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.
What is the function of the harmonic balancer?
The harmonic balancer is an engine component found on virtually all rotating internal combustion engines and plays an important role in protecting the engine from dangerous harmonic vibrations and potential damage.
What are the symptoms of a bad harmonic balancer?
Another more serious symptom of a problem with the harmonic balancer is a separated harmonic balancer. If the rubber layer in the harmonic balancer dries or wears out, it can cause the entire harmonic balancer to completely fail by separating.
Do you need elastomer damper for harmonic balancer?
It is participating rather than reacting.” The OEM style balancers are designed to smooth out harmonics at a specific rpm, but the minute an engine builder goes in and changes to a different crank, stroke or whatever, that OEM balancer is no longer going to work. You would need an elastomer damper, according to balancer manufacturers.
What is the purpose of a crankshaft harmonic balancer?
The crankshaft harmonic balancer is a device connected to the front of an engine’s crankshaft, usually built into the crankshaft pulley. Its purpose is to absorb and reduce harmonic vibrations from the engine as the crankshaft rotates, as harmonic vibrations at high engine speeds can…
How do I change the harmonic balancer on my car?
Every engine is different, so if you want to change the harmonic balancer on your car, you’ll need to search around various car forums and Web sites to see how it’s done on your specific model. Generally, you’ll want to remove the belt from the crankshaft pulley and then take the harmonic balancer mounting bolt off with a socket and ratchet.
Why do you need a harmonic imbalancer in your engine?
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.
One of the first symptoms of a potential problem with the harmonic balancer is engine vibration. The harmonic balancer is specifically designed to absorb harmonic engine vibrations as engine speeds rise. If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively.
How do you know if your harmonic balancer is bad?
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.
When do you need to replace a harmonic balancer?
There is no fixed time for this but there are symptoms from which it can be inferred that the balancer needs a replacement. As time goes by, the harmonic balancer attached to the crankshaft can go bad due to continuous contact with chemicals, from other elements and/or from old age.
Signs of a Bad Crankshaft Harmonic Balancer Increased Engine Vibration. When the crankshaft balancer loses its harmonic functions, the issue it is supposed to control comes out in full force. Disrupted Timing Marks. The crankshaft harmonic balancer is usually found in the front of the crankshaft pulley and is attached to the crankshaft. Detached Harmonic Balancer. Loud Noise from the Engine Bay.
