What happens when harmonic balancer is bad?
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.
Why is my crank pulley 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. You can remove these pulleys using the standard tools. Then, check them for flatness or rust. Sometimes, some dirt may get trapped under the pulley.
