The engine crank pulley is a critical component that plays a vital role in the overall performance of an internal combustion engine. Its primary function is to convert the rotational energy generated by the crankshaft into kinetic energy, which is then transferred to the serpentine belt. The crank pulley is typically located at the front of the engine and serves as the drive point for various accessories such as the alternator, power steering pump, and air conditioning compressor. In some engines, the crank pulley also serves as a harmonic balancer, helping to reduce vibrations and improve overall engine stability.
