Why does a crankshaft pulley break?
Similarly, you may ask, why would a crankshaft pulley break?
When an engine has a bearing failure, the excessive clearance can cause the crank to have a “jump rope” effect inside the engine. The crankshaft can bend severely or even break in some cases. In cases where a nitrided crankshaft is bent, it is usually not recommended to straighten.
Secondly, does the crankshaft pulley move? The camshaft and crankshaft pulleys are directly attached to the engine (camshaft and crankshaft) and will only rotate if the engine is running or manually rotating the engine by placing a socket and breaker bar to the crankshaft pulley bolt.
Just so, how do I know if my crankshaft pulley is bad?

- 2) Alternator Failure. The crankshaft pulley is responsible for powering the alternator.
- 3) Power Steering Pump Failure.
