The crankshaft pulley (pulley damper) is a device designed to damp or prevent mechanical vibrations in the system of internal combustion engines. The task of the pulley is to rotate the belt drive of the gas distribution mechanism and additional equipment, to provide a shock-absorbing effect under loads, to absorb vibrations.

This part serves as a means of transferring torque from the crankshaft to the attachment using transmission belts. In addition, it is designed to smooth out vibrations in the operation of the crankshaft (if additionally equipped with a damper - a rubber layer between the working disc and the inner cage).

It should be noted that the pulley, along with other parts in the motor, is responsible for the well-coordinated operation of several mechanisms in the car, and its failure causes many unpleasant problems. They have special teeth and grooves for toothed belts. This type is used in most modern passenger cars. It is worth noting that all the pulleys need auxiliary parts - washers and bolts of the corresponding brands.
