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.
The good news is, the harmonic balancer can easily be repaired with a kit that usually retails for under $10.
Cost of Harmonic Balancer Replacement On average for most vehicles, it can cost about $200 to replace a harmonic balancer.
Hello – No, welding the harmonic balancer to the crankshaft is not a good idea for at least 2 reasons. … Welding the hub to the crank will almost certainly pass enough heat to the rubber portion of the balancer to damage it.
A faulty balancer can result in a knocking, rattling, or squeaking sound that corresponds with engine speed. In some cases, the noise is bad enough to be mistaken for an internal engine problem.
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. And without it, you can do damage to the crankshaft and the engine bearings.
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.
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.
if the squealing only occured when the car started it would be more likely a water pump bearing. If it only occurs when you enage the AC then it is a compressor issue. A harmonic balancer reduces vibration by allowing some slipage between the belts and the engine.
“A repair sleeve will fix the end of your harmonic balancer.
The air conditioning compressor has a clutch on it that should spin freely as well but it will not be rotating the internals of the compressor. … That you cannot rotate either cam or crankshaft pulleys by hand is completely normal. If you were able to rotate them bare handed, THEN you would have a problem.
If the torque is not set properly, the engine vibration and running of the drive belt over the harmonic balancer can cause the harmonic balancer pulley to loosen and fly off the engine. … A professional or a repair manual should be consulted for the correct torque for your vehicle.
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.
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.
The purpose of the harmonic balancer is to reduce engine vibration and in many cases, serves as a pulley for drive belts. … 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.
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.
The job of the balancer is to help eliminate these harmonics before the cause problems. The circular device, made of rubber and metal, is bolted at the front end of the crankshaft to help absorb vibrations. It’s usually connected to the crank pulley, which drives accessories like the air conditioner.Mar 5, 2019
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.
In spite of its name, a Harmonic Balancer does not actually balance the rotating assembly. It absorbs torsional vibration so it is not transfered to the other parts of the engine. This is why it is also called a “damper” or “dampener”.

If you don’t have a puller or you don’t want to buy it, you can use a durable strap in pulling it. Simply insert the strap in the space and around to position the strap firmly around the center of the balancer. Then secure and pull the strap to remove the pulley. It will surely do the trick.
Is a harmonic balancer bolt reverse thread? Yes, that bolt is normal thread, counterclockwise loosens it. The engine turns the opposite direction as the bolt removal direction to gaurantee that it won’t back out.
How often should you replace harmonic balancer? How long should a 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.
The repair of a crankshaft is a very difficult and tedious process that requires true mechanical knowledge, and is best left to the professionals. There are various types of crankshaft repair, like polishing, crankshaft pulley repair, canal cleaning, bearing replacement, crankshaft balancing, dressing, and grinding.
How long does a crankshaft pulley last? They should last 70k ish, trouble is when you buy a new one its not a new one, its one that has been sitting on a shelf in a FGP warehouse for ten years.
