Components of the 4376175 Overhaul Kit by Cummins

O Ring Seal (3678756)

The O Ring Seal is a critical component within the 4376175 Overhaul Kit, ensuring that all fluid systems within the engine remain sealed and leak-free. Its role is to provide a tight seal around various engine components, preventing the escape of oils and other fluids, which is essential for maintaining engine efficiency and longevity.

Oil Pan Gasket (4026684)

The Oil Pan Gasket is designed to seal the oil pan to the engine block, preventing oil leaks. This gasket is vital for maintaining the engine’s lubrication system integrity, ensuring that oil is retained within the system to lubricate moving parts and reduce friction.

Upper Engine Gasket Set (4352145)

The Upper Engine Gasket Set includes various gaskets that seal the upper portion of the engine, such as the cylinder head to the engine block. These gaskets are essential for maintaining the engine’s compression and preventing coolant and oil leaks, which are critical for engine performance and reliability.

Pressure Relief Valve (4357177)

The Pressure Relief Valve plays a role in regulating the pressure within the engine’s lubrication system. By relieving excess pressure, it protects the engine from damage due to over-pressurization, ensuring smooth operation and prolonging the life of engine components.

Lubricating Oil Filter (4367100)

The Lubricating Oil Filter is responsible for removing contaminants from the engine oil, ensuring that the oil remains clean and effective in lubricating engine components. This filter is essential for maintaining engine health by preventing wear and tear caused by impurities in the oil.

Engine Piston Kit (4376243)

The Engine Piston Kit includes pistons, piston rings, and other related components that are essential for the engine’s combustion process. These components work together to ensure efficient combustion, proper sealing of the combustion chamber, and smooth operation of the engine.

Fuel Filter (4920586)

The Fuel Filter is designed to remove impurities from the fuel before it reaches the engine’s combustion chamber. This ensures that the engine receives clean fuel, which is crucial for efficient combustion, reduced emissions, and prolonged engine life.

Main Bearing Kit (5406110)

The Main Bearing Kit includes bearings that support the crankshaft within the engine block. These bearings are essential for reducing friction and wear between the crankshaft and the engine block, ensuring smooth rotation and efficient engine operation.

Liner Kit (5472970)

The Liner Kit consists of cylinder liners that provide a smooth surface for the pistons to move within the engine block. These liners are crucial for maintaining engine efficiency, reducing friction, and ensuring proper sealing of the combustion chamber.

Conclusion

The Cummins 4376175 Overhaul Kit is a comprehensive solution for maintaining and repairing heavy-duty truck engines. By providing high-quality components and facilitating thorough engine overhauls, this part ensures that engines are restored to optimal condition, enhancing performance, reliability, and longevity. Regular maintenance and adherence to manufacturer guidelines are essential for maximizing the benefits of this Cummins part.
