Components of Cummins Oil Cooler Seal Kit 3801198

The Cummins Oil Cooler Seal Kit, identified by the part number 3801198, is meticulously designed to ensure the integrity and efficiency of the oil cooling system. Each component within this kit plays a role in maintaining the seal and functionality of the oil cooler assembly. Below is a detailed look at the components included in this kit and their specific roles:

• 67946 Plain Washer: This component serves as a spacer or shim within the assembly, ensuring proper alignment and spacing between other components. Its role is in maintaining the structural integrity of the oil cooler.

• 212161 O Ring Seal: The O ring seal is fundamental in preventing oil leaks by creating a tight seal around moving or stationary parts within the oil cooler. Its elasticity allows it to conform to irregularities on mating surfaces, ensuring a leak-proof environment.

• 218245 Lubricating Oil Cooler Cover Gasket: This gasket is positioned between the oil cooler cover and the cooler itself. Its primary function is to seal the cover to the cooler, preventing oil from escaping and contaminants from entering the cooling system.

• 3006745 Retaining Ring: The retaining ring is used to secure components in place within the oil cooler assembly. It ensures that parts such as seals and gaskets remain in their designated positions, contributing to the overall stability and functionality of the system.

• 3007713 O Ring Seal: Similar to the 212161 O ring seal, this component is essential for sealing connections within the oil cooler. It helps in maintaining the pressure and purity of the oil circulating through the cooler.

• 3008017 Oil Cooler Support Gasket: This gasket provides a seal between the oil cooler and its support structure. It is vital for preventing oil leaks at this junction and ensuring that the cooler is securely mounted.

• 3010030 Lubricating Oil Cooler Cover Gasket: Acting as a duplicate or replacement for the 218245 gasket, this component ensures that there is no failure in the sealing process should one gasket need to be replaced or if the kit is used for a repair involving both covers.

• 3023868 Bypass Valve Body Gasket: This gasket seals the bypass valve body within the oil cooler system. It is crucial for maintaining the integrity of the bypass function, which allows oil to flow around the cooler when necessary, ensuring consistent oil temperature and pressure.

• 3045979 O Ring Seal: Another O ring seal included in the kit, this component is used in various sealing applications within the oil cooler assembly. Its flexibility and durability make it an essential part of the kit, ensuring that all connections are sealed effectively.

Conclusion

The Cummins Oil Cooler Seal Kit 3801198 is a vital component for maintaining the efficiency and reliability of heavy-duty truck engines.
