Every time the cylinders fire, torque is transferred into the crankshaft. The crankshaft deflects under this torque, which sets up vibrations when the torque is released. At certain engine speeds the torque imparted by the cylinders are in synch with the vibrations in the crankshaft, which results in a phenomenon called resonance This resonance causes stress beyond what the crankshaft can withstand, resulting in crankshaft failure. The accessory pulley acts as a balancer and prevents these vibrations from destroying your crankshaft.
