Crankshaft Pulley

Product Description

AEP Part No. - 21653150

This is a brand new Crankshaft Pulley.

The crank pulley (also called crankshaft damper, torsional damper, or vibration damper) is connected to the crankshaft of an engine to reduce torsional vibration.

When the engine is started, torque is imparted to the crankshaft. The crankshaft deflects under this torque, which sets up vibrations when the torque is released. At certain engine speeds the torques imparted by the cylinders are in synch with the vibrations in the crankshaft, which results in resonance. This resonance causes stress beyond what the crankshaft can withstand, resulting in crankshaft failure.

To prevent this vibration, the Crankshaft pulley is attached to the front of the crankshaft. The Pulley is composed of mass and an energy dissipating element. The mass resists the acceleration of the vibration and the energy dissipating (rubber/clutch/fluid) element absorbs the vibrations.

Over time, the energy dissipating (rubber/clutch/fluid) element can deteriorate from age, heat, cold, or exposure to oil or chemicals. Unless rebuilt or replaced, this can cause the crankshaft to develop cracks, resulting in crankshaft failure.

Our products are backed by a comprehensive warranty, which means in the unlikely event of failure due to defective workmanship or materials within twelve months of fitting, the product will be replaced free of charge.
