Its role in these systems contributes to the overall efficiency and reliability of the truck. Proper function of the pivot shaft bracket ensures that these systems operate smoothly, which is vital for the truck’s performance.

Integration with Throttle Lever

The Pivot Shaft Bracket securely mounts the throttle lever, allowing it to pivot smoothly around a fixed point. This pivot point is critical for the lever’s function, as it enables the driver or operator to modulate the engine’s throttle with ease. The bracket ensures that the lever’s motion is consistent and reliable, which is vital for maintaining engine performance and responsiveness ⁴.

Connection to Throttle Bracket

The Pivot Shaft Bracket interfaces directly with the Throttle Bracket, forming a stable connection that supports the lever’s movement. This connection is designed to withstand the forces exerted during operation, ensuring that the throttle lever remains aligned and functional. The stability provided by the bracket is essential for the accurate transmission of the driver’s inputs to the engine’s throttle system.

Role in Throttle Control Bracket Assembly

In the Throttle Control Bracket assembly, the Pivot Shaft Bracket plays a supporting role by providing a mounting point for other components. It helps in maintaining the structural integrity of the assembly, ensuring that all parts work in unison. This is particularly important in high-stress environments where the reliability of the throttle control system is paramount.

Functionality within Throttle Kit

When incorporated into a Throttle Kit, the Pivot Shaft Bracket enhances the kit’s overall performance by ensuring smooth and precise throttle operation. The bracket’s design allows for easy installation and adjustment, making it a versatile component in various throttle kit configurations. Its role in the kit is to provide a solid foundation for the throttle lever, enabling fine-tuned control over the engine’s throttle.

Conclusion

The Cummins 3930407 Pivot Shaft Bracket is a key component in the efficient operation of engine systems, particularly those involving throttle control. Its role in supporting and facilitating the movement of the throttle lever is essential for the accurate and reliable modulation of engine power.
