Throttle Lever Spring
Cummins®

The Throttle Lever Spring, part number 173717, manufactured by Cummins, is a critical component designed for use in commercial trucks. Cummins, a well-established name in the automotive industry, is renowned for its commitment to quality and innovation. This spring plays a significant role in the throttle control system of trucks, contributing to the overall performance and efficiency of the vehicle ¹.

Basic Concepts

Throttle lever springs are integral to the throttle control system in vehicles. Their primary function is to return the throttle lever to its default position when the accelerator pedal is released. This ensures that the engine operates within the desired parameters and maintains a consistent idle speed. The spring interacts with the throttle lever, accelerator pedal, and other components to facilitate smooth and responsive throttle control ².

Purpose and Function

The Throttle Lever Spring 173717 is designed to assist in maintaining the desired throttle position in a truck. When the accelerator pedal is pressed, the throttle lever moves, allowing more air into the engine and increasing power output. Upon releasing the pedal, the spring returns the lever to its original position, ensuring the engine returns to idle or the previously set throttle position. This mechanism is vital for smooth engine performance and efficient operation ³.

Key Features

The Throttle Lever Spring 173717 boasts several key features that enhance its performance and durability. Its design is engineered to withstand the rigors of commercial truck operation, ensuring reliable function over time. The spring is made from high-quality materials, providing resilience and longevity. Additionally, its precise engineering ensures consistent performance, contributing to the overall reliability of the throttle control system.

Benefits

Incorporating the Throttle Lever Spring 173717 into a truck’s throttle control system offers several advantages. Improved throttle response allows for more precise control over the engine’s power output, enhancing drivability. Enhanced fuel efficiency is another benefit, as the spring helps maintain optimal throttle positions, reducing unnecessary fuel consumption. Furthermore, the spring’s robust construction increases reliability, ensuring consistent performance even in demanding operating conditions.

Installation and Maintenance

Proper installation of the Throttle Lever Spring 173717 is crucial for ensuring optimal performance. The installation process may require specific tools and should be carried out according to the manufacturer’s guidelines to avoid damage to the spring or other components. Routine maintenance is also important to ensure the spring remains in good condition. This may include periodic inspections for signs of wear or damage and ensuring that all related components are functioning correctly.

Troubleshooting

Common issues with the Throttle Lever Spring 173717 may include difficulty in returning the throttle lever to its default position or inconsistent throttle response. These symptoms can often be traced back to a faulty spring. Troubleshooting steps may involve inspecting the spring for visible damage, testing its tension, and ensuring that all related components are functioning correctly. If a fault is detected, the spring may need to be replaced or repaired to restore proper function.

Role of Part 173717 Throttle Lever Spring in Engine Systems

The Throttle Lever Spring, identified as part 173717, is an essential component in the orchestration of various engine systems. It is intricately involved in the modulation of the throttle, which in turn regulates the fuel and air mixture entering the engine.

When integrated with the Throttle Assembly Lever and the Throttle Lever Assembly, the spring ensures smooth and consistent movement of the throttle lever. This is vital for maintaining the desired engine speed and performance. The spring’s tension aids in the return motion of the Throttle Lever after it has been actuated, ensuring that the throttle does not remain in an open position longer than necessary.

In conjunction with the Lever and Link Assembly and the Throttle Lever Link, the spring contributes to the precise control of the throttle position. This is particularly important in systems where fine adjustments are required, such as in the Vernier Throttle Control.

The spring also interacts with the Pierce Governor and the Solenoid and Mounting Valve. Here, it assists in the governor’s function to maintain a steady engine speed under varying loads by providing the necessary force to adjust the throttle lever position.

Furthermore, the Throttle Lever Spring works in tandem with the EBM: Lever and the Lever Throttle to ensure that the throttle response is immediate and accurate. This is especially important in systems where rapid changes in engine speed are required.

In fuel systems, such as those with a Fuel Sub 24V Pump, the spring’s role is to maintain a consistent throttle position, which directly affects the fuel delivery rate. This ensures that the engine receives the correct amount of fuel for the given operating conditions.

Lastly, the spring is part of the Throttle Linkage & Gov. system, where it helps in the smooth transmission of motion from the operator’s control to the throttle mechanism itself. This is essential for the overall efficiency and responsiveness of the engine system.

Conclusion

The Throttle Lever Spring 173717 is a vital component in the throttle control system of commercial trucks. Its role in ensuring smooth and responsive throttle control, maintaining engine performance, and enhancing fuel efficiency cannot be overstated. Proper installation, maintenance, and troubleshooting are essential to ensure the longevity and reliability of this Cummins part.
