Crankshaft Pulley
An automotive crankshaft pulley is a component located at the front of an engine that is responsible for transferring power from the engine's crankshaft to the various accessories that are driven by the engine. The crankshaft pulley is typically made of cast iron or aluminum and is bolted onto the front of the crankshaft. The pulley contains one or more grooves, which correspond to the various belts that drive the engine accessories such as the alternator, water pump, power steering pump, and air conditioning compressor. As the engine crankshaft rotates, it spins the pulley, which in turn drives the accessory belts and powers the various engine accessories. The size and design of the crankshaft pulley can affect the performance of the engine, as a larger or heavier pulley can cause increased rotational mass, reducing the engine's horsepower and efficiency. Proper maintenance of the crankshaft pulley is important to ensure that it operates smoothly and that the accessory belts are properly tensioned. The pulley should be inspected for signs of wear or damage and replaced as necessary to prevent failure and potential damage to the engine or accessories.

When choosing a crankshaft pulley, first confirm the year, make, and engine size. Next, determine the type of belt (V-belt or serpentine belt) you will be using as well as the number of grooves. Next confirm the pulley will match the other pulleys (for example, small block Chevy short or long water pump applications). Finally, from the remaining compatible options, choose the crankshaft pulley that matches your finish, application, and budget needs.
