Role of Part 3681287 Shim in Engine Systems

Part 3681287 Shim is an essential component in ensuring the precise operation of various engine systems. Its primary function is to provide the necessary clearance adjustments between moving parts, which is vital for the efficient and reliable performance of the engine.

Lubricating Oil Pump

In the lubricating oil pump, this part plays a significant role in maintaining the correct clearance between the pump’s rotor and stator. This ensures that the pump operates within its designed parameters, providing optimal oil flow and pressure. Proper clearance is essential for preventing metal-to-metal contact, which could lead to increased wear and potential failure of the pump.

Lubricating Oil Pump Kit

When integrated into a lubricating oil pump kit, the shim helps in fine-tuning the pump’s performance during installation or maintenance. By adjusting the clearance, technicians can ensure that the pump meets the specific requirements of the engine, enhancing lubrication efficiency and prolonging the lifespan of engine components.

Lubricating Pump Kit

Similarly, in a lubricating pump kit, Part 3681287 Shim allows for precise adjustments that are crucial for the pump’s reliable operation. This is particularly important in high-performance or high-stress applications where even minor deviations can impact overall engine health.

Overhaul Kit

In an overhaul kit, the shim is often used to restore or modify clearances during engine rebuilds. This ensures that all components within the engine, including the oil pump, operate with the correct tolerances. Proper clearance adjustments are key to achieving smooth operation and preventing premature wear.

Conclusion

The Cummins 3681287 Shim is a critical component for maintaining the precise operation and efficiency of commercial truck engines. Its role in providing necessary clearance adjustments between components ensures optimal performance and longevity of the engine systems. Regular maintenance and proper installation are essential for maximizing the benefits of this part.
