Role of Part 3006342 Throttle Lever Stop in Engine Systems

The Throttle Lever Stop, identified by part number 3006342, plays a significant role in ensuring the precise operation of various engine components. Its primary function is to limit the travel of the throttle lever, thereby controlling the amount of fuel delivered to the engine. This is essential for maintaining the desired power output and ensuring efficient engine performance.

In conjunction with the fuel pump and fuel pump housing, the Throttle Lever Stop helps regulate the fuel supply. This is particularly important in systems where the fuel pump is calibrated to specific performance parameters. The stop ensures that the fuel pump does not over-deliver, which could lead to inefficient combustion or even engine damage.

When integrated with the FP & Gov Sump (Fuel Pump & Governor Sump), the Throttle Lever Stop assists in maintaining the correct fuel-air mixture. This is vital for the operation of components like the fuel aftercooler pump and the fuel D B. H. pump, where precise fuel delivery is necessary to achieve optimal cooling and performance.

In systems utilizing the fuel pump AFC-VS (Aftercooler Fuel Control - Variable Speed), the Throttle Lever Stop ensures that the variable speed functionality operates within safe limits. This is important for the fuel pump aftercooler body and the fuel pump housing assembly, where consistent and controlled fuel flow is required to prevent overheating and ensure longevity of the components.

Additionally, the Throttle Lever Stop is instrumental in scenarios where the fuel pump is paired with calibration options such as fuel pump @ cal code or fuel pump and cal. code. These calibrations are designed to fine-tune the engine’s performance under various operating conditions, and the stop ensures that these calibrations are not exceeded.

For engines equipped with the non-AFC VS FP/Gov. Sump, the Throttle Lever Stop provides a mechanical limit that complements the governor’s role in fuel management. This is particularly relevant in maintaining the integrity of the fuel pump body and the fuel pump housing, ensuring they operate within their designed parameters.

In summary, the Throttle Lever Stop (part 3006342) is a key component in the orchestration of fuel delivery and engine performance. It works in tandem with various fuel system components to ensure that the engine operates efficiently and within its specified limits, thereby contributing to the overall reliability and performance of the engine system.
