Detroit Diesel

The crankshaft shoulder pulley is a vital component in the engine's accessory drive system, designed with precision dimensions to ensure optimal power transmission. Its 117.50 mm width and 188 mm diameter, with a 14-groove V-belt configuration, allow efficient transfer of rotational energy from the crankshaft to auxiliary components. Made from cast iron, this pulley features a painted finish that enhances corrosion resistance and durability under strenuous operating conditions. The V-groove design ensures secure belt engagement, reducing slippage and wear over time. The pulley’s robust construction provides stability during high-torque scenarios, supporting the engine’s overall reliability. Proper installation of this pulley is key to maintaining consistent belt tension and preventing misalignments that could lead to belt failure or accessory malfunction. This component is an essential part of the engine's drive system, and Source One Parts Center supplies it to ensure your engine’s auxiliary systems operate smoothly and efficiently.
