Role of Part 4970950 Plain Washer in Engine Systems

In the context of engine systems, the part 4970950 Plain Washer is utilized to ensure the proper functioning and longevity of various components. Here’s how it integrates with specific engine parts:

Filter Systems

The Plain Washer is often employed in filter systems to maintain a secure connection between the filter housing and the engine block. This ensures that the filter remains properly seated, allowing for efficient filtration of contaminants from the engine oil. A well-seated filter prevents oil leaks and maintains the integrity of the filtration process, which is essential for engine performance and durability.

Lubricating Oil Pathways

In lubricating oil systems, the Plain Washer plays a role in sealing connections within the oil pathways. This includes the interfaces between the oil pump, oil galleries, and various engine components. By providing a reliable seal, the Plain Washer helps maintain consistent oil pressure and flow, which is vital for the lubrication of moving parts and the reduction of friction and wear.

Filter Kit Assemblies

When installing a filter kit, the Plain Washer is used to ensure that all components within the kit are properly sealed. This includes the connections between the filter housing, the filter element, and any associated plumbing. A secure seal is necessary to prevent oil leaks and to ensure that the filter kit functions as intended, providing clean oil to the engine.

Lubricating Oil Filter Head

The Plain Washer is also integral to the assembly of the lubricating oil filter head. It ensures that the filter head is tightly connected to the engine block or the filter housing. This connection is important for maintaining the structural integrity of the filter assembly and for ensuring that the filter head can effectively manage the flow of oil through the filtration system.

Oil Bypass Filter

In systems equipped with an oil bypass filter, the Plain Washer is used to seal the connections between the bypass filter and the main oil filtration system. This ensures that the bypass filter can effectively manage excess oil flow during high-demand situations, preventing overloading of the primary filter and maintaining optimal engine lubrication.

Overall, the part 4970950 Plain Washer is a small yet significant component in ensuring the reliability and efficiency of engine systems by providing necessary seals and connections in various critical applications.
