Compatibility with Engine Models

The Cummins Lockplate part number 3628969 is designed to fit seamlessly with a range of Cummins engine models. This lockplate is an essential component in securing various parts within the engine assembly, ensuring that the engine operates efficiently and reliably.

K38 and K50 Engines

The Lockplate 3628969 is compatible with both the K38 and K50 engine series. These engines are known for their robust construction and are often used in heavy-duty applications. The lockplate ensures that the engine’s internal components remain securely fastened, preventing any movement that could lead to mechanical failure.

QSK38 and QSK50 Engines

For the QSK38 and QSK50 engines, the Lockplate 3628969 is specifically engineered to fit these models. The QSK series is designed for high-performance applications, and the lockplate plays a crucial role in maintaining the integrity of the engine’s assembly. This part is particularly important in the QSK38 CM2150 MCRS and QSK50 CM2150 MCRS models, where it helps in securing the components under high-stress conditions.

Additional Models

The Lockplate 3628969 also fits the QSK38 CM850 MCRS and QSK50 CM2350 K108 engines. These models benefit from the lockplate’s ability to maintain precise alignment and secure fastening of engine parts, ensuring optimal performance and longevity.

Role of Part 3628969 Lockplate in Engine Systems

The Part 3628969 Lockplate is an essential component that ensures the secure fitting and alignment of various engine components. Its primary function is to maintain the integrity and stability of the engine’s exhaust system and related assemblies.

Exhaust Manifold and Related Components

In the exhaust system, the Lockplate plays a significant role in the Exhaust Manifold Mounting Assembly and the Exhaust Manifold Mounting. It secures the Exhaust Manifold to the engine block, ensuring that there are no gaps or misalignments that could lead to exhaust leaks. This is particularly important in high-performance engines where precise fitting is necessary to maintain efficiency and reduce emissions.

For engines with Exhaust Left Bank Manifold and Exhaust Right Bank Manifold, the Lockplate ensures that these manifolds are correctly positioned and tightly secured. This is vital for balanced exhaust flow, which contributes to overall engine performance and longevity.

Turbocharger Integration

When a Turbocharger is part of the engine system, the Lockplate assists in the secure mounting of the Exhaust Manifold Conversion Kit. This kit often requires precise alignment to ensure that the turbocharger can operate efficiently. The Lockplate helps in maintaining this alignment, thus supporting the turbocharger’s function in boosting engine performance.

Cylinder Head and Gasket Sets

The Lockplate also interacts with the Quad Cylinder Head Gasket Set and the Quadrant Cylinder Hardware Gasket Set. By ensuring that these gaskets are correctly positioned and secured, the Lockplate helps in maintaining the seal between the cylinder head and the engine block. This is essential for preventing coolant or oil leaks, which could otherwise lead to engine damage.

Upper Engine Gasket Kit

In the context of the Upper Engine Gasket Kit, the Lockplate ensures that all components within this kit are properly aligned and secured. This includes the Single Head Gasket Kit and the Single Head Gasket Set, which are critical for maintaining the integrity of the upper engine assembly.

Manifold Exhaust Mounting

Finally, the Lockplate is instrumental in the Manifold Exhaust Mounting. It ensures that the manifold is correctly attached to the exhaust system, facilitating smooth and efficient exhaust flow. This is particularly important in engines where the exhaust system plays a significant role in performance, such as in high-revving engines or those with forced induction.

Conclusion

In summary, the Cummins Lockplate 3628969 is a versatile and essential component that ensures the secure assembly of various Cummins engine models, including the K38, K50, QSK38, and QSK50 series. Its role in maintaining the integrity and stability of the engine’s exhaust system and related assemblies is crucial for the overall performance, efficiency, and reliability of the engine system.
