Can a harmonic balancer be rebuilt?
Also know, what happens if your harmonic balancer goes 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.
Accordingly, how do I know if my harmonic balancer is bad?
Signs of a Bad Crankshaft Harmonic Balancer
- Increased Engine Vibration.
- Disrupted Timing Marks.
- Detached Harmonic Balancer.
- Loud Noise from The Engine Bay.
- Rubber Ring Going Bad.
- Check Belts.
- Listen for Irregular Beats.
The harmonic balancer should not wobble at all. Before you condemn the motor for having rod or crankshaft knock you should have the crankshaft harmonic balancer checked for a broken one. If it is bad then it can cause a loud knocking noise.
