What happens when the harmonic balancer goes 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.

How do I know if my harmonic balancer is bad?

The most common symptoms of a bad harmonic balancer include:

1. Engine Vibrations. The harmonic balancer’s job is to dampen vibrations applied to the crankshaft.
2. Noticeable Harmonic Balancer Wobble.
3. Unusual Noises.
4. Illuminated Check Engine Light.
5. Visible Wear or Damage.

How long will a bad 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. This is a good example – because it’s got such a massive piece of rubber – you can see the rubber literally tears apart into two sections.

Will a car start with a bad harmonic balancer?

Bad Ignition Timing/No Start Without a functioning harmonic balancer your vehicle’s ignition timing will be thrown off. According to the automotive diagnostic website AA1 Car, bad ignition timing is due to an erratic signal from the camshaft sensor caused by harmonic balancer’s inability to stabilize the component.

When should I replace 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.

Why is my harmonic balancer wobbling?

Excessive belt tension. An over-tightened belt may cause crankshaft snout runout and harmonic balancer wobble.

Is crankshaft pulley same as harmonic balancer?

A harmonic balancer is a front end accessory drive component that is connected to the crankshaft of an engine. Harmonic balancers do have many names, though, such as damper, crankshaft pulley and crankshaft balancer, among others.

Is it bad to drive without a harmonic balancer?

The harmonic balancer is essentially part of the crankshaft pulley. And without it, you can do damage to the crankshaft and the engine bearings.

Do harmonic balancers wear out?

Harmonic balancers do have many names, though, such as damper, crankshaft pulley and crankshaft balancer, among others. While this part may not wear, or be known to wear, as quickly as a traditional idler pulley or belt tensioner, balancers do in fact wear and eventually must be replaced.

Should I replace harmonic balancer bolt?

As long as it’s not over tighten (as with any bolt really) it still can be used. If it’s something as simple as a harmonic balancer bolt I don’t worry about it. Now if it’s head bolts or main bolts then I’ll replace them. Even though they generally can be reused.

How do you test a harmonic balancer?

Start your engine and check the harmonic balancer to see if it wobbles while the engine is running. Take a flashlight and shine it directly onto the balancer to see if it goes in and out while rotating. If it wobbles, the harmonic balancer is bad. Turn off the ignition.

What are the symptoms of a bad harmonic balancer?

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.

What are the symptoms of a bad crankshaft harmonic balancer?

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.

How do you remove the harmonic balancer bolt?

Insert one bolt through each corner of the puller and into the balancer. Tighten each bolt with a wrench. Remove the harmonic balancer. To remove the balancer, turn the threaded rod which runs through the center of the puller in a clockwise direction with a wrench.
