Components of the 3804612 Overhaul Kit

The 3804612 Overhaul Kit by Cummins is a comprehensive assembly designed to facilitate the complete restoration of an engine to its original working condition. Each component within this kit plays a critical role in ensuring the engine’s reliability, performance, and longevity post-overhaul. Below is a detailed description of the key components included in this kit and their respective roles:

• Retaining Ring (175755): This component is essential for securing various parts within the engine, ensuring they remain in place under operational conditions. Its role is to prevent the displacement of critical components, thus maintaining the integrity of the engine’s assembly.

• Piston Pin (191970): The piston pin connects the piston to the connecting rod, allowing for the conversion of linear motion into rotational motion. Its durability and precision are vital for the smooth operation of the engine.

• Connecting Rod Bearing (214950): These bearings are crucial for reducing friction between the connecting rod and the crankshaft. They ensure smooth operation and are pivotal in maintaining the engine’s efficiency and longevity.

• Rectangular Ring Seal (215090): This seal is used to prevent leaks between mating surfaces within the engine. Its role is critical in maintaining the engine’s pressure integrity and preventing the escape of fluids or gases.

• O Ring Seal (3032874): Similar to the rectangular ring seal, the O ring seal is employed in various applications throughout the engine to ensure a tight seal, preventing leaks and maintaining system pressure.

• Cylinder Liner (3065405): The cylinder liner provides a smooth surface for the piston to move against, reducing wear on the cylinder walls. It is a critical component for maintaining compression and efficiency within the engine.

• Engine Piston (3095746): As one of the core components of the engine, the piston is responsible for converting the energy from the combustion process into mechanical motion. Its condition directly affects the engine’s performance and efficiency.

• Oil Pan Gasket (3099083): This gasket seals the oil pan to the engine block, ensuring that engine oil remains contained within the lubrication system. Its integrity is essential for maintaining proper lubrication and preventing oil leaks.

• Main Bearing - Standard Set (3801260): Main bearings support the crankshaft within the engine block, reducing friction and wear. Their condition is critical for the smooth operation and longevity of the engine.

• Upper Engine Gasket Set (4024920): This set includes various gaskets that seal the upper portion of the engine, including the cylinder head to block interface. These gaskets are vital for maintaining compression and preventing leaks.

• Piston Ring Set (4089489): Piston rings seal the combustion chamber, control oil consumption, and transfer heat from the piston to the cylinder walls. Their condition directly impacts the engine’s efficiency, power output, and oil consumption.

Conclusion

The Cummins 3804612 Overhaul Kit is an essential tool for maintaining and repairing truck engines, offering a comprehensive set of components designed to restore engines to like-new condition.
