This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
Belt Operation That Is Too Loud Or Damage When the harmonic balancer starts to wear out, it stops performing its other function as a pulley for the drive belts on your car. This means that the belts on your engine may slip, make more noise, or become damaged. You may notice that you are unable to accelerate effectively as a result of this, that your fuel economy drops, and that your engine misfires or backfires.
What kinds of issues can be brought on by a defective harmonic balancer?
The engine will shake to an extreme degree if the harmonic balancer becomes too worn out or fails and is no longer able to absorb the harmonic vibrations in the correct manner. When traveling at higher speeds, the shaking will become even more evident, which will put more strain on the engine.
Is there a relationship between harmonic balancer and timing?
Timing marks that are not aligned properly are another indication that there may be a issue with the harmonic balancer. Timing marks are susceptible to movement if the layers become separated or slip. Because of this, accurately timing the engine using a timing light will be challenging at best and impossible in most cases.

How exactly does one put a harmonic balancer through its paces?
Turn on your vehicle’s engine and observe the harmonic balancer to determine whether or not it shakes when the engine is operating. To determine whether the balancer moves in and out as the wheel is turning, shine the light from a flashlight straight onto it. If it shakes, the harmonic balancer is not working properly. Remove the key from the ignition.
Does a harmonic balancer require balancing in order to function properly?
Harmonic balancers are not what they are called. Instead of balancing an engine, they work to absorb and eliminate undesired vibration caused by torsional twisting of the crankshaft…. Dampeners function similarly to torsional shock absorbers and are installed in engines to reduce the amount of torsional twist and vibration.
Is it possible for a vehicle to function without a harmonic balancer?
Without the harmonic balancer, you would not have any air conditioning, power steering, alternator, or water pump… And if you don’t have it, you risk damaging the bearings in the engine as well as the crankshaft. Thus, you will need to replace it as soon as possible.
Does the size of a harmonic balancer matter?
When it comes to the harmonic balancer that you install on an engine, size really does matter despite what any other person may tell you.
