Here's why:
* Crankshaft pulley: It's directly attached to the crankshaft, the main rotating shaft of the engine. The crankshaft pulley transmits power from the engine to the alternator (and other accessories) via the belt.
* Harmonic balancer: This name is more accurate for the specific type of crankshaft pulley often used in modern engines. It's designed to dampen vibrations and harmonics generated by the engine, making it smoother and quieter.
While the crankshaft pulley is the primary name, referring to it as a harmonic balancer is technically more accurate, especially in modern cars.
