Components of the 3356972 Overhaul Kit by Cummins

Engine Piston Kit (3802747)

The engine piston kit is a fundamental component of the 3356972 Overhaul Kit. It includes essential parts such as pistons, piston rings, and possibly wrist pins. This kit is designed to replace worn-out pistons and rings, ensuring the engine’s cylinders maintain proper compression and efficiency. The piston kit plays a critical role in the overall performance and longevity of the engine by reducing friction and wear.

Salvage Sleeve (3904166)

The salvage sleeve is included to address issues with worn or damaged cylinder walls. By installing a salvage sleeve, technicians can restore the cylinder to its original dimensions without the need for a complete engine rebuild. This component is crucial for maintaining the engine’s compression and preventing oil consumption, thereby extending the engine’s operational life.

Piston Pin (3934047)

The piston pin, also known as the wrist pin, connects the piston to the connecting rod. It allows for the smooth transfer of motion from the piston to the crankshaft. The inclusion of a new piston pin in the overhaul kit ensures that this critical connection remains strong and reliable, reducing the risk of mechanical failure during engine operation.

Oil Pan Gasket (3938162)

The oil pan gasket is a sealing component that prevents oil leaks from the oil pan. A fresh gasket is vital in an overhaul kit to ensure that the engine’s lubrication system remains intact. Proper sealing of the oil pan is essential for maintaining oil pressure and preventing contamination of the engine’s internal components.

Upper Engine Gasket Set (4089649)

The upper engine gasket set includes various gaskets that seal the upper portion of the engine, such as the cylinder head gasket, intake manifold gasket, and exhaust manifold gasket. These gaskets are critical for maintaining the engine’s combustion efficiency and preventing coolant or oil leaks. Replacing these gaskets during an overhaul ensures that the engine operates within optimal parameters.

Conclusion

The Cummins 3356972 Overhaul Kit is a comprehensive solution for maintaining and restoring heavy-duty truck engines. By providing essential replacement parts and ensuring optimal engine performance, this kit plays a vital role in the longevity and reliability of heavy-duty engines. Regular maintenance, proper installation, and adherence to safety guidelines are key to maximizing the benefits of this overhaul kit.
