Incomplete Turbocharger Kit
Cummins®

The 3798351RX Incomplete Turbocharger Kit, manufactured by Cummins, is a specialized product designed for commercial trucks. This kit is integral to the turbocharger system, offering essential components for its operation. Unlike a complete kit, this Cummins part may not include all parts required for a full replacement, such as certain housings or external plumbing. Understanding its role and application is crucial for maintaining and upgrading truck engines.

Basic Concepts of Turbocharging

Turbocharging technology enhances an internal combustion engine’s efficiency and power output by forcing extra air into the combustion chamber ¹. A turbocharger comprises a turbine and a compressor connected by a shaft. Exhaust gases spin the turbine, which in turn spins the compressor, drawing in and compressing air. This compressed air allows for more fuel to be burned, resulting in increased power.

A complete turbocharger kit typically includes all components required for a full replacement, such as the turbocharger core, housings, and necessary plumbing. An incomplete kit, like the 3798351RX, may include core components but require the user to source or reuse certain parts like the turbocharger housing or external piping.

Components of Cummins Incomplete Turbocharger Kit 3798351RX

Compressor Wheel

The compressor wheel is a critical component of the turbocharger kit. It is responsible for compressing the intake air before it enters the engine, thereby increasing the engine’s efficiency and power output. This component is essential for the proper functioning of the turbocharger.

Turbine Wheel

The turbine wheel works in conjunction with the compressor wheel. It is driven by the exhaust gases from the engine, which spin the turbine wheel at high speeds. This, in turn, drives the compressor wheel, creating a continuous cycle of compressed air intake and exhaust gas expulsion.

Center Housing Rotating Assembly (CHRA)

The CHRA is the heart of the turbocharger. It houses both the compressor and turbine wheels and is responsible for the high-speed rotation required for efficient turbocharging. The CHRA is a complex assembly that requires precision engineering to function correctly.

Bearings

Bearings are crucial for the smooth operation of the turbocharger. They support the rotating assembly and reduce friction, allowing the compressor and turbine wheels to spin at high speeds without wearing out prematurely. High-quality bearings are essential for the longevity and performance of the turbocharger.

Seals

Seals are used throughout the turbocharger to prevent leaks of oil, air, and exhaust gases. They ensure that the turbocharger operates efficiently and safely by maintaining the integrity of the system. Proper sealing is critical for the overall performance and reliability of the turbocharger.

Oil Feed Line

The oil feed line supplies lubrication to the turbocharger’s moving parts. Adequate lubrication is vital for reducing wear and tear on the bearings and other components, ensuring that the turbocharger operates smoothly and efficiently.

Wastegate Actuator

The wastegate actuator is part of the wastegate system, which controls the amount of exhaust gas that bypasses the turbine wheel. This helps regulate the boost pressure produced by the turbocharger, preventing over-boosting and ensuring stable engine performance.

Boost Control Solenoid

The boost control solenoid is an electronic component that regulates the boost pressure by controlling the wastegate. It receives signals from the engine control unit (ECU) to adjust the wastegate position, thereby fine-tuning the turbocharger’s performance to match the engine’s requirements.

Gaskets and O-Rings

Gaskets and O-rings are used to create seals between various components of the turbocharger. They are essential for preventing leaks and ensuring that the turbocharger operates within specified parameters. High-quality gaskets and O-rings are critical for the turbocharger’s durability and efficiency.

Mounting Brackets

Mounting brackets are used to secure the turbocharger to the engine. They provide a stable and secure attachment point, ensuring that the turbocharger remains in place during operation. Proper mounting is essential for the turbocharger’s performance and longevity.

Conclusion

The 3798351RX Incomplete Turbocharger Kit is a valuable component for enhancing the performance and efficiency of commercial truck engines. Its precise engineering, high-quality materials, and targeted repair capabilities make it a cost-effective solution for maintaining and upgrading turbocharger systems. Regular maintenance and proper installation are key to maximizing the benefits of this Cummins part.
