Components of the Cummins Turbocharger Repair Kit 3545479

Plain Washer (3504967)

The plain washer is a fundamental component in the turbocharger repair kit. It serves as a spacer and load distributor, ensuring even pressure distribution across the turbocharger assembly. This helps in maintaining the integrity and alignment of other components during the repair process.

Turbocharger Thrust Bearing (3524285)

The turbocharger thrust bearing is critical for the proper functioning of the turbocharger. It supports the axial loads generated during operation, ensuring smooth rotation and reducing wear on the turbocharger shaft. This bearing is essential for maintaining the turbocharger’s efficiency and longevity.

O Ring Seal (3524693)

The O ring seal is vital for creating a tight, leak-proof seal in various joints and connections within the turbocharger. It prevents the escape of pressurized air and oil, which is crucial for maintaining the turbocharger’s performance and preventing contamination.

Retaining Ring (3526103)

The retaining ring secures components in place within the turbocharger assembly. It is used to hold bearings, seals, and other parts in their correct positions, ensuring that they do not move or become misaligned during operation. This is important for the overall stability and reliability of the turbocharger.

Split Ring Seal (3527368 and 3527546)

The split ring seals are designed to provide a reliable seal in applications where a continuous seal might be difficult to install. These seals are used in various turbocharger components to prevent leaks and ensure that the turbocharger operates efficiently. Their split design allows for easy installation and removal during the repair process.

Regular Hexagon Nut (3529372)

The regular hexagon nut is a common fastening component used throughout the turbocharger repair kit. It is used to secure various parts together, ensuring that the assembly remains intact under operational stresses. Its hexagonal shape allows for easy tightening and loosening with standard tools.

Turbocharger Bearing (3533194)

The turbocharger bearing supports the rotating shaft of the turbocharger, allowing it to spin smoothly and efficiently. Proper bearing function is essential for reducing friction and wear, which directly impacts the turbocharger’s performance and lifespan.

Thrust Ring (3533196)

The thrust ring works in conjunction with the thrust bearing to manage axial loads within the turbocharger. It helps in maintaining the proper alignment and spacing of components, ensuring that the turbocharger operates smoothly and efficiently.

Hexagon Head Set Screw (5329304)

The hexagon head set screw is used for precise adjustments and secure fastening within the turbocharger assembly. It allows for fine-tuning of components and ensures that parts remain in their correct positions, contributing to the overall performance and reliability of the turbocharger.
