Role of Part 111670 Tube Brace in Engine Systems

The Part 111670 Tube Brace is an integral component in the structural integrity and efficient operation of various engine systems. Its application spans across multiple subsystems, enhancing both performance and reliability.

Breather & Filler and Related Components

In the breather & filler system, the Tube Brace provides essential support to the breather mounting tube and the crankcase breather. This support ensures that the breather system maintains optimal alignment and structural stability, which is vital for the efficient venting of gases from the crankcase. Additionally, it aids in the secure attachment of the engine breather and oil filler, contributing to a leak-free environment.

Engine Control Module and Fuel Systems

For the engine control module (ECM) and fuel systems, the Tube Brace plays a supportive role in the fuel pump coupling and fuel pump plumbing. By providing a stable mounting point, it ensures that the fuel lines and couplings remain securely in place, reducing the risk of fuel leaks and maintaining consistent fuel delivery to the engine.

Oil Systems

In oil systems, the Tube Brace is utilized in the oil fill arrangement and oil gauge setup. It ensures that the oil fill tube and gauge are properly aligned and supported, facilitating accurate oil level readings and secure oil filling processes. This is particularly important in high-performance engines where precise oil levels are essential for optimal lubrication.

Pressure and Manifold Systems

The Tube Brace is also integral in pressure tube manifolds, where it supports the manifold structure, ensuring even distribution of pressure across the system. This is crucial for components like the rocker lever housing and support, where consistent pressure is required for reliable operation.

Turbocharger Systems

In turbocharger applications, the Tube Brace is employed in turbocharger mounting, plumbing, and vent plumbing. It provides the necessary support for turbocharger water supply mounting, ensuring that the turbocharger remains securely attached and aligned. This support is vital for maintaining turbocharger efficiency and preventing performance issues due to misalignment.

Valve Cover & Filler and Vent Systems

For the valve cover & filler and vent systems, the Tube Brace supports the vent and mounting tube, as well as the vernier throttle. This support ensures that the vent tubes remain properly aligned, facilitating efficient venting of gases from the valve cover and maintaining stable throttle operation.

Jacobs Brake and Throttle Accessory Support

Lastly, in systems involving the Jacobs brake and throttle accessory support, the Tube Brace provides the required structural support. This ensures that these components remain securely in place, contributing to the overall reliability and performance of the engine system.
