Can a bad harmonic balancer ruin your engine?

A harmonic balancer has rubber internal construction. When it fails it either rips off completely or wobbles. If it rips off it can go through the radiator or other engine parts. A wobble will negate its purpose of absorbing damaging resonance vibrations, and the crankshaft may break.

Can a bad harmonic balancer cause engine failure?

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.

Can a car run with a bad harmonic balancer?

The harmonic balancer also acts as a pulley for your vehicle's drive belts so when it begins to fail your engine's belts may slip, operate noisily or become damaged. You may experience this as an inability to accelerate efficiently, dips in fuel economy and engine misfiring or backfiring.

What happens when your harmonic balancer goes out?

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.

Can you run an engine without harmonic balancer?

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. ... And without it, you can do damage to the crankshaft and the engine bearings.

How do I know if my harmonic balancer has slipped?

There is a scribe mark on the face of the balancer you can see while it is installed. The mark is chiseled across between the center hub and the outer ring. Rotate the engine with a 3/4 wrench and look closely for the mark. If the mark on the hub is not aligned with the mark on the ring then it is slipped.

Can a bad harmonic balancer cause power loss?

These can wear down over time, especially when engine performance modifications are made to increase torque. A failing harmonic balancer can cause catastrophic engine damage.

Does harmonic balancer affect timing?

Another symptom of a potential problem with the harmonic balancer is, misaligned timing marks. If the layers separate or slip, the timing marks can shift. This will make it, difficult if not impossible; to properly time the engine with a timing light.

Can a bad harmonic balancer cause overheating?

Most likely the harmonic balancer is not the reason for why the car is overheating. ... I recommend having a certified mechanic, such as one from YourMechanic, come to your home or office to check the cooling systemfor any malfunctioning that is leading to the overheating.

How much does it cost to replace a harmonic balancer?

The cost to replace the harmonic balancer could be around $100 to $500 depending on your vehicle type.

What happens if crankshaft pulley breaks?

When a crankshaft pulley fails (or the timing belt due to a badly maintained crankshaft pulley), the timing of the engine is completely thrown off. Even a rotation or movement of a few millimetres can start to cause problems in a system so precise.

Is crankshaft pulley same as harmonic balancer?

Is a crankshaft pulley and harmonic balancer the same thing? - Quora. No! They are two different things. The harmonic balancer slides onto the front of the crankshaft which has a keyway on it to keep it from slipping and a bolt and wide washer holds it in place.

Can a harmonic balancer leak oil?

The reason for such a nifty product to exist is after time the Neoprene timing cover seal wears a deep groove into the steel snout of the harmonic balancer. This allows oil to leak from the timing cover and if the oil leak is left neglected, road dirt and grime attracts to oil-covered areas and sticks.

Is a harmonic balancer necessary?

Lastly, friction-style dampers rely on internal clutch discs to quell harmonics. “High-performance balancers are necessary to prolong the life of your engine,” said Nick Orefice, of Fluidampr. ... Uncontrolled torsional vibration can damage and reduce the life of engine components.

How important is a crankshaft pulley?

How the Crankshaft Pulley Reduces Damage. Located outside the engine block, the crankshaft pulley is essential to ensure other engine components operate in unison to allow the vehicle to run smoothly.

What does the harmonic balancer do?

The harmonic balancer helps minimize torsional crankshaft harmonics and resonance. The damper is composed of two elements: an inertia mass and an energy dissipating element. Most often made of rubber, this element may be composed of a synthetic elastomer, a clutch, a spring or fluid.

What causes a crank pulley to wobble?

If the fan-belt pulleys that bolt to the harmonic balancer are dismounted, bent, or distorted, it may cause the crankshaft pulley to wobble. ... Sometimes, some dirt may get trapped under the pulley. Furthermore, the crankshaft pulley tends to wobble if it isn't appropriately torqued.

How do I know if my crankshaft pulley is bad?

The most common symptoms of a bad crankshaft pulley are engine vibration and irregular engine idle. It may also result in a damaged alternator, power steering pump, or a failed transmission if you are unlucky.

How long do harmonic balancers last?

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.
