What happens if harmonic balancer is loose?
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.
Can a failed harmonic balancer cause a crankshaft to break?
What Happens When a Harmonic Balancer Fails. Although the harmonic balancer may seem simple enough, if it fails, it can cause major problems. Without the balancer dampening unwanted crankshaft vibrations, engine failures, such as worn rod bearings and a broken crankshaft, may result.
What makes a harmonic balancer go bad?
Over time, the crankshaft harmonic balancer can go bad from constant exposure to chemicals, the elements, or from old age. If this happens, the crankshaft may develop cracks and ultimately fail.
What happens when the harmonic balancer goes bad?
This harmonic balancer is designed to absorb the vibrations of the engine as you accelerate faster. But if the balancer starts to go bad for any reason, the vibrations won’t be absorbed anymore. This will cause the engine to shake profusely the faster you go.
What happens when the crankshaft pulley goes bad?
But if the balancer starts to go bad for any reason, the vibrations won’t be absorbed anymore. This will cause the engine to shake profusely the faster you go. 2) Alternator Failure. The crankshaft pulley is responsible for powering the alternator. So naturally, if the crankshaft pulley goes bad, then you can expect the alternator to stop working.
How much does it cost to replace a crankshaft balancer?
The cost to replace a bad crankshaft pulley/harmonic balancer is anywhere from $350 to $400. The cost of labor is around $150 to $180 and the cost of parts is around $200 to $220. It is not the most expensive replacement job, but it is not too cheap either.
