The key’s offset design allows it to fit snugly within the specified grooves of the engine components, ensuring that the shafts and pulleys remain in precise alignment. This alignment is crucial for the efficient transfer of power and the overall longevity of the engine.

K50 Engine

Similar to the K19 and K38, the K50 engine also relies on this part. This engine, known for its robust performance, benefits from the key’s ability to maintain the alignment of its rotating components. The precise fit and durability of the key contribute to the engine’s reliability and operational efficiency.

V903 Engine

The V903 engine, another model in the Cummins lineup, also utilizes this part. This engine’s design incorporates the key to ensure that the various shafts and pulleys operate in perfect harmony. The key’s role in maintaining alignment is vital for the V903’s performance, particularly under heavy-duty conditions.

Grouping by Design and Application

The K19, K38, and K50 engines, while distinct in their specifications, share a similar design philosophy that emphasizes reliability and efficiency. The use of this part across these models underscores its importance in maintaining the integrity of the engine’s mechanical components. The V903 engine, though different in its configuration, also benefits from this key’s precision fit and durability, ensuring optimal performance and longevity.

Role of Part 200708 Offset Woodruff Key in Engine Systems

This part is integral to the synchronization and secure fitting of various components within an engine system. Its application ensures precise alignment and reliable operation of key engine parts.

Integration with Camshaft and Gear Systems

In the context of the camshaft and gear assembly, the Offset Woodruff Key facilitates the accurate positioning of the camshaft. This alignment is essential for the camshaft to interact correctly with the valve train, ensuring optimal valve timing and engine performance. The key’s offset design allows for minor adjustments in the camshaft’s position, which can be vital for fine-tuning engine operation.

Function in Left Bank Camshaft Applications

For the left bank camshaft (L.B. Camshaft), the Offset Woodruff Key plays a similar role. It secures the camshaft in place relative to the crankshaft, maintaining the necessary timing between the two. This is particularly important in engines with multiple camshafts, where precise timing is required to avoid interference and ensure smooth operation.

Role in Injector Alignment

The Offset Woodruff Key is also used in the alignment of injectors. Proper positioning of injectors is crucial for fuel delivery timing, which directly impacts combustion efficiency and engine performance. The key ensures that injectors are correctly aligned with the engine’s combustion chambers, contributing to consistent fuel delivery and combustion.

Application in Long Block Assemblies

In a long block assembly (such as the Long Block Assy. - 50), the Offset Woodruff Key is employed to secure various rotating components. This includes not only camshafts but also gears and other rotating parts that require precise alignment. The key’s role in these assemblies helps maintain the integrity of the engine’s timing and operational harmony.
