Cummins Engine Part 4371673: Banjo Connector Screw

The 4371673 Banjo Connector Screw is a critical component in the Cummins engine ecosystem, specifically designed to ensure secure and leak-proof connections in various fluid systems. This part is integral to the operational integrity of several Cummins engines, including the QSK19, CM850, and MCRS series.

QSK19 Series

In the QSK19 series, the 4371673 Banjo Connector Screw is utilized in the fuel and hydraulic systems. Its primary function is to maintain a tight seal between the banjo fitting and the fuel line or hydraulic hose, preventing any leaks that could compromise engine performance or safety. The QSK19 engines, known for their robust design and high performance, rely on such precision components to deliver consistent power and reliability.

CM850 Series

For the CM850 series, the 4371673 Banjo Connector Screw plays a crucial role in the engine’s cooling and lubrication systems. Ensuring that coolant and oil flow through the system without any interruptions is vital for maintaining optimal engine temperatures and preventing wear and tear. The CM850 engines, often used in heavy-duty applications, benefit from the durability and precision of this part, contributing to their longevity and efficiency.

MCRS Series

In the MCRS series, the 4371673 Banjo Connector Screw is employed in both the fuel and lubrication systems. The MCRS engines, designed for marine applications, require components that can withstand the harsh marine environment. This part ensures that all connections are secure and leak-proof, which is essential for the safety and reliability of marine vessels. The precision and quality of this screw are critical in maintaining the performance of the MCRS engines under demanding conditions.

By integrating the 4371673 Banjo Connector Screw into these engines, Cummins ensures that each component works seamlessly together, providing the reliability and performance that their customers expect.

Role of Part 4371673 Banjo Connector Screw in Engine Systems

The 4371673 Banjo Connector Screw is instrumental in ensuring the seamless operation of various engine systems. In the context of the motor, this component facilitates the secure connection of hydraulic lines, which are essential for the operation of the fuel injection system. It ensures that the high-pressure fuel lines maintain integrity, preventing leaks and ensuring consistent fuel delivery to the injectors. This reliability is paramount for the motor’s performance, as any inconsistency in fuel delivery can lead to inefficient combustion and reduced engine efficiency.

When considering the starting system, the 4371673 Banjo Connector Screw plays a supportive role by ensuring that the hydraulic lines connected to the starter motor’s actuators are securely fastened. This connection is vital for the precise operation of the starter motor, which relies on hydraulic pressure to engage the flywheel and initiate engine cranking. The secure fitting provided by the Banjo Connector Screw ensures that hydraulic pressure is maintained, allowing for a smooth and reliable start-up process.
