Role of Part 3034986 Rectangular Ring Seal in Engine Systems

The 3034986 Rectangular Ring Seal is integral to maintaining the integrity and efficiency of various engine systems. Its application spans across multiple components, ensuring optimal performance and longevity.

Integration with Bearing and Gasket Components

In bearing and gasket assemblies, the 3034986 Rectangular Ring Seal provides a reliable barrier against oil and gas leakage. When integrated into a bearing/gasket kit, it enhances the seal between moving parts, reducing friction and wear. This is particularly important in high-stress areas where precision and durability are paramount.

Application in Oil Pan and Lubricating Systems

The seal is frequently used in oil pan assemblies, including the EBM (Engine Block Module) pan and oil systems. It ensures that the oil pan gasket set maintains a tight seal, preventing oil leaks that could lead to engine damage. Additionally, in the lubricating oil suction tube and mounting transfer tube, the seal helps maintain consistent oil flow, which is essential for proper lubrication of engine components.

Role in Piston/Liner and PDC BM Assembly

In the PDC (Piston/Liner) and PDC BM (Bearing Module) assembly, the 3034986 Rectangular Ring Seal plays a key role in sealing the interfaces between the piston, liner, and bearing module. This seal is vital for maintaining compression and preventing oil contamination in the combustion chamber.

Usage in Lower Engine Gasket and Overhaul Kits

The seal is also a component in lower engine gasket sets and overhaul kits. Its inclusion in these kits ensures that during engine maintenance or rebuilds, all critical sealing points are addressed. This comprehensive approach helps in achieving a leak-free engine, enhancing overall performance and reliability.

Function in Suction and Plumbing Arrangements

In suction arrangements and oil pan plumbing, the 3034986 Rectangular Ring Seal ensures that the suction tube and transfer tubes remain sealed. This is important for maintaining the efficiency of the oil circulation system, which is crucial for engine cooling and lubrication.

Summary of Component Interactions

• Bearing/Gasket and Bearing/Gasket Kit: Enhances seal integrity and reduces friction.
• EBM Pan and Oil Systems: Prevents oil leaks and maintains oil flow.
• PDC and PDC BM Assembly: Ensures compression and prevents oil contamination.
