Precision and reliability in engine control are paramount for any commercial vehicle. The 1124111800010 Retracting Spring of Throttle is a critical, yet often overlooked, OEM component that ensures exactly that in FOTON trucks. This spring plays a vital role within the throttle assembly, guaranteeing the throttle valve returns to its idle position smoothly and consistently every time the accelerator pedal is released. As a fundamental part among genuine Foton truck parts, the 1124111800010 is essential for maintaining optimal fuel efficiency, reducing emissions, and ensuring predictable vehicle behavior. A failure in this small component can lead to serious drivability and safety issues, making the genuine 1124111800010 spring a key item for proactive maintenance and repair.

The 1124111800010 is a torsion spring specifically designed for the throttle body assembly of FOTON diesel engines. Its primary function is mechanical and failsafe: to provide a consistent return force that closes the throttle plate when the driver’s foot is lifted from the accelerator pedal. In modern engines with electronic throttle control (ETC), this spring works as a critical backup system to the electronic motor, ensuring the throttle can default to a safe idle position even in the unlikely event of an electronic system failure.
This component is engineered for thousands of cycles under high-temperature and vibration-prone conditions in the engine bay. The precise tension and fatigue resistance of the genuine 1124111800010 spring are calibrated to match the specific throttle body design, ensuring smooth operation without sticking or binding. Choosing the correct 1124111800010 OEM part is therefore not just about fitment, but about preserving the engineered safety and response profile of your FOTON truck’s engine management system.
Using a non-OEM or incorrect tension spring for part number 1124111800010 can have significant consequences. A spring with too weak a tension may cause delayed throttle closure or a high idle speed, impacting fuel economy and emissions. Conversely, a spring that is too strong can make the accelerator pedal feel heavy, increase wear on the throttle shaft, and potentially strain the electronic throttle actuator. The genuine 1124111800010 component guarantees the exact specified return force and durability, maintaining the vehicle’s original performance and safety margins.
Ensures immediate and consistent closure of the throttle valve to the idle position, providing predictable engine deceleration and pedal feel.
Acts as a crucial mechanical failsafe in electronic throttle systems, promoting a “fail-idle” condition for enhanced vehicle safety.
Prevents throttle “hang-up” at higher-than-desired angles, directly contributing to proper idle fuel control and lower emissions.
The following table provides detailed technical data for the genuine 1124111800010 Retracting Spring, based on common specifications for such OEM throttle components.
| Parameter | Specification / Details |
|---|---|
| OEM Part Number | 1124111800010 |
| Product Name | Retracting Spring Of Throttle / Throttle Return Spring |
| Brand | FOTON (Original Equipment Manufacturer) |
| Primary Material | High-Carbon Spring Steel (Oil-Tempered for Heat Resistance) |
| Spring Type | Torsion Spring |
| Surface Finish | Protective Coating (e.g., Zinc or Phosphate) for Corrosion Resistance |
| Core Function | To provide mechanical return force for the throttle valve plate. |
| Compatible Systems | Throttle Body Assembly (Both mechanical linkage and electronic throttle control – ETC) |
| Key FOTON Engine/Model Fit | Commonly found in throttle bodies for FOTON ISF 2.8L, 3.8L diesel engines and associated truck models (Auman, Ouhuo, etc.) |
Recognizing the signs of a worn or failed 1124111800010 spring is crucial for preventive maintenance. A compromised spring can manifest in several drivability issues:
If you observe any of these symptoms, inspecting the throttle body and specifically the 1124111800010 return spring should be a priority. Do not ignore these signs, as they can affect safety and operational costs.
Replacing the 1124111800010 spring typically requires access to the throttle body assembly. For safety, the battery should be disconnected, especially on vehicles with electronic throttle control, to prevent unintended throttle actuation. The old spring is carefully removed, noting its exact orientation and mounting points. The new genuine 1124111800010 spring is then installed in the identical position.
It is critical that the spring is not over-stretched or twisted during installation, as this can permanently alter its tension. After installation, a basic relearn procedure for the electronic throttle body may be required on some FOTON models to reset the ECU’s learned idle position. Always refer to vehicle-specific service information. This part, 1124111800010, is compatible with a range of FOTON commercial vehicles equipped with the relevant throttle body, including popular series like Auman, Ouhuo, and Tornado.
The 1124111800010 Retracting Spring of Throttle is a perfect example of a small component with a massive responsibility. It sits at the heart of the engine’s air control system, ensuring precise throttle operation, fuel efficiency, and, most importantly, vehicle safety. For fleet managers and owners of FOTON Auman, Ouhuo, and other models, specifying the genuine 1124111800010 OEM part during repairs is a non-negotiable best practice. It guarantees the correct mechanical properties and fit, preserving the engineered performance and reliability of your commercial vehicle. Never compromise on a component that directly controls your engine’s power.
