When a crankshaft pulley fails (or the timing belt due to a badly maintained crankshaft pulley), the timing of the engine is completely thrown off. Even a rotation or movement of a few millimetres can start to cause problems in a system so precise.

What tool is used to remove crankshaft pulley?
Q: What tool is used to remove the crankshaft pulley? The tool suitable for removing a crankshaft pulley is a half-inch drive impact gun. You could also use a torque wrench to secure it properly.
What happens if the harmonic balancer breaks?
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. A faulty balancer can damage the belt and engine-driven accessories as well.
What pulley is making noise?
Does a crankshaft pulley spin freely?
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.
How do I stop my crankshaft pulley from turning?
How do I turn my crankshaft pulley by hand?
The most precise way to rotate the engine over by hand is to place a large socket on the front crankshaft bolt, attach a long ratchet wrench, and rotate the crank. The longer the wrench handle the more precise the movement.
Can you run an engine without a harmonic balancer bolt?
Indeed, if it’s the crank pulley and the harmonic balancer comes off with it and the engine continues to run that can damage the crankshaft. That would be very bad. Other pulleys could get distorted if a fastener is missing and in such condition could damage the drive belt riding on the pulley.
