Where is the harmonic balancer on a four cylinder engine?
Harmonic balancer lower pulley on a four-cylinder engine. A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be interference fit to the crankshaft in order to operate in an effective manner.
Can a harmonic balancer be removed from a car?
When used on street driven vehicles, the damper manufacturer can provide inspection and service intervals based on the particulars of the engine the damper is being used on. Some performance enthusiasts have been known to remove the harmonic balancer, believing that its mass reduces engine performance.
Can a bad harmonic balancer cause an engine to shake?
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 does a harmonic balancer lower pulley do?
Jump to navigation Jump to search. Harmonic balancer lower pulley on a four-cylinder engine. A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft.
How does a harmonic balancer Balance Your engine?
Contrary to what the name sounds like, a harmonic balancer does not balance your engine literally. Instead, it removes and absorbs unwanted vibrations. This vibration it absorbs comes from the torsional twisting of your engine’s crankshaft. This balancer is simply a circular device made of rubber and steel.
What are the symptoms of a bad harmonic balancer?
They are usually made of rubber and metal, which easily absorbs any harmonic vibrations that could harm the engine otherwise. Usually a problem with the harmonic balancer will produce a few symptoms that can alert the driver of a potential problem that should be serviced.
What causes the timing marks on a harmonic balancer to shift?
Misaligned timing marks. The harmonic balancers found on many vehicles are constructed as two pieces of metal with a rubber layer in between to dampen the vibrations. If the layers separate 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.
Why is a harmonic balancer called a dampener?
Harmonic balancers are often called dampeners, and in truth, they are dampeners in their effect. In operation, Dampeners are similar to a torsional shock absorber, which helps prevent vibration from the engine and dampen torsional twist.
