What are the symptoms of a bad crankshaft pulley?

[Arya]

Crankshaft pulley damage has a significant impact on the vehicle. The car's power performance will be very poor, and the engine may produce unusual sounds when idling or accelerating. Below is a detailed introduction to the crankshaft pulley: 1. The car pulley is mainly installed on the car engine crankshaft to drive the camshaft, water pump, generator, air conditioning compressor, power steering pump, and other components. 2. The function of the pulley: It drives the water pump, generator, and air conditioning compressor to work. The water pump ensures the normal water circulation of the engine for cooling purposes. The generator charges the battery to ensure the normal operation of various electrical circuits in the car. The air conditioning pump, also known as the compressor, is used in the air conditioning system. 3. Advantages of pulley drive: The pulley drive can mitigate load impacts; it operates smoothly with low noise and vibration. The structure of the pulley drive is simple and easy to adjust. The manufacturing and installation precision of the pulley drive is not as strict as that of meshing drives. The pulley drive has an overload protection function. The center distance between the two shafts in the pulley drive can be adjusted over a wide range.
