The crankshaft pulley is an important part of the timing belt drive and other auxiliary elements of the internal combustion engine. The product is located at the front of the shaft. The pulley drives the camshaft, cooling fan, generator, power steering pump, pneumatic system compressor, etc. In addition, the part performs the functions of damping along with the flywheel and balancers. This becomes possible due to the fact that during the production of automobile pulleys, they are balanced using special equipment. This device, together with other parts of the power plant, is used to ensure the coordinated work of a variety of mechanisms in the car. Therefore, in the event of its premature failure, one has to face various unpleasant moments.
