A crankshaft pulley is also referred to as a harmonic balancer, crankshaft damper, vibration damper and crank pulley damper. It is a device which connects directly to the crankshaft of a vehicle’s engine to reduce the torsional vibrations as well as serves as a sort of pulley for the drive belts. Each time that the engine is fired up, there is torque exerted on the crankshaft. So, the crankshaft will deflect when the torque is applied which will set up numerous vibrations as the torque is released. Some engines exert a larger torque and will sync with the vibrations of the crankshaft resulting in what’s called ‘resonance.’ This resonance ends up causing stress much beyond what the crankshaft can handle causing failure. It is in these cases that a vehicle will need to be thoroughly inspected, and the pulley replaced.
In most cases if there is a problem with the crankshaft pulley your car will refuse to start. Some vehicles will turn on the ‘check engine’ light. If you happen to experience any of these problems, then visit a certified mechanic. The mechanic should be able to determine the cause of the failure and then recommend replacing all the associated parts.
There are various size and types of crankshaft pulleys, and so you need to buy one that’s made especially for your vehicle. This can be achieved by searching via part number. However, if you still have a problem you can contact us directly, and we can help you find the right one for your vehicle.
