The V Ribbed Belt 3697256 is compatible with the ISG12 CM2880 G107 and QSG12 CM2880 G112 engines. These engines are part of the Cummins G-series, known for their robust performance and reliability in various applications. The belt’s design ensures it can handle the specific torque and rotational speeds of these engines, providing a stable and durable connection between the engine’s crankshaft and the ancillary components.

QSG12/X12 CM2350 G110

The V Ribbed Belt 3697256 also fits the QSG12/X12 CM2350 G110 engine. This engine, part of the Cummins Q-series, is engineered for high-performance applications, offering a balance of power and efficiency. The belt’s precision engineering ensures it can withstand the demands of this engine, maintaining optimal tension and alignment to prevent slippage and ensure longevity.

Role of Part 3697256 V Ribbed Belt in Engine Systems

The V ribbed belt, specifically part 3697256, is an essential component in the efficient operation of various engine systems. It is primarily responsible for transferring rotational force from the crankshaft to other auxiliary components, ensuring their synchronized operation.

Integration with the Belt System

In the engine’s belt system, the V ribbed belt plays a pivotal role. It is designed to fit snugly within the belt routing system, which includes pulleys and tensioners. The belt’s ribbed design enhances its grip on the pulleys, reducing slippage and ensuring consistent power transmission. This setup is vital for maintaining the proper function of components driven by the belt, such as the alternator, power steering pump, and air conditioning compressor.

Connection to the Fan Drive

The fan drive is another component where the V ribbed belt is integral. The belt connects to the fan drive pulley, which is responsible for rotating the engine cooling fan. As the crankshaft turns, the V ribbed belt transmits this motion to the fan drive, causing the fan to rotate and draw air through the radiator. This process is essential for dissipating heat from the engine, preventing overheating, and maintaining optimal operating temperatures.

Ensuring Smooth Operation

To ensure the smooth operation of the V ribbed belt within these systems, it is important to maintain proper tension and alignment. The belt tensioner automatically adjusts the belt’s tension, accommodating wear and thermal expansion. Regular inspection and maintenance of the belt and associated components are recommended to prevent issues such as belt wear, cracks, or misalignment, which can lead to decreased efficiency or complete failure of the driven components.

Conclusion

The Cummins 3697256 V Ribbed Belt is a critical component in the operation of heavy-duty trucks, ensuring the efficient and reliable performance of engine accessories.
