Detroit Diesel

This cast iron belt pulley is integral to the engine's accessory drive system, translating rotational power from the crankshaft to various components such as the alternator, power steering, and water pump. Its precise dimensions, including a width of 111 mm and an outer diameter of over 234 mm, ensure proper fitment and balanced operation within the belt drive assembly. The multiple grooves accommodate even load distribution and reduce belt slippage, enhancing overall system efficiency. Made from durable cast iron, it provides resistance to wear and thermal stresses, which are common in heavy-duty applications. The bolt circle and bore diameter are meticulously designed for secure mounting and alignment, critical for maintaining belt tension and preventing premature component wear. This pulley’s reliable construction helps maintain engine accessory operation, contributing to vehicle reliability and performance.
