Crankshaft pulley

The crankshaft pulley sits on the end face of the crankshaft and transmits its rotational motion to the auxiliary drive belt. This belt drives important components such as the alternator, air conditioning compressor, power steering pump, and water pump. Depending on the design, the crankshaft pulley is either a simple pulley or a vibration damper with an integrated elastomer ring. Especially in modern engines, it not only transmits power but also reduces crankshaft vibrations, thus contributing to smooth running and protecting adjacent components. Crucial factors include an exact fit, the correct diameter, the number of grooves, material quality, and precise centering. Defective or worn crankshaft pulleys can lead to belt running problems, vibrations, noise, or damage to auxiliary components. At Autoteile Gossau, you'll find crankshaft pulleys in original and aftermarket quality for many vehicle models.
