How To Change Out Harmonic Balancer On 1999 Buick Century Youtube
Symptoms of a Bad or Failing 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 every bit the crankshaft rotates, as harmonic vibrations at high engine speeds can crusade accelerated wear and impairment to the components. They are usually made of condom and metallic, which easily absorbs whatsoever harmonic vibrations that could harm the engine otherwise. Usually a trouble with the harmonic balancer volition produce a few symptoms that can warning the driver of a potential problem that should be serviced.
ane. Engine vibration
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 quondam 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.
two. Misaligned timing marks
Another symptom of a potential problem with the harmonic balancer is misaligned timing marks. The harmonic balancers constitute on many vehicles are constructed as ii pieces of metal with a rubber layer in between to dampen the vibrations. If the layers dissever or slip, the timing marks, which are usually stamped into the front of the pulley, can shift and thus throw off the placement of the timing marks. This will brand information technology difficult, if not impossible to properly fourth dimension the engine with a timing light.
3. Separated harmonic balancer
Another more serious symptom of a trouble 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 past separating. If the harmonic balancer separates, the engine belts will usually come up off and the vehicle will be left without engine accessories.
The harmonic balancer is an engine component found on virtually all rotating internal combustion engines and plays an important function in protecting the engine from unsafe harmonic vibrations and potential damage. For this reason, if yous suspect that your harmonic balancer may be having an consequence, have the vehicle inspected by a professional technician, such as one from YourMechanic. They will be able to determine if the vehicle needs a crankshaft harmonic balancer replacement.
