Product Description

Unrivaled Precision Engineering

Exceptional Compatibility

Premium - Grade Construction

The Cummins 3925009 compression spring, bearing the distinct part number 3925009, exemplifies unrivaled precision engineering. This number isn't just a code; it represents the high - quality standards Cummins upholds in manufacturing this vital component. As a direct replacement part, it ensures a seamless fit within Cummins engine systems, embodying reliability and excellence. The manufacturing process adheres to strict tolerances, with dimensional accuracy maintained within ±0.05mm for critical dimensions, guaranteeing a perfect match for installation.

This compression spring is engineered for extensive compatibility with Cummins engines. Specific Engine Models: It functions seamlessly with the 5.9L and 6.7L Cummins engines. In 5.9L Cummins engines, which were installed in Dodge Ram trucks from 1994 - 1998, it plays a crucial role in maintaining optimal oil pressure. By exerting a consistent force of 50 - 60 N within the oil pressure system, it ensures smooth operation and prevents damage caused by abnormal pressure. For 6.7L Cummins engines, it regulates and maintains safe oil pressure levels between 3 - 5 bar, which is essential for long - term reliability. Additionally, it is compatible with models like the QSB6.7 and integrates well across the QSB, QSC, and QSL series engines. In the QSB6.7 engine, it helps in proper valve operation, ensuring efficient combustion by precisely controlling the valve opening and closing times within a tolerance of ±0.02 milliseconds.

Crafted from high - strength alloy steel with a tensile strength of over 1500 MPa, the 3925009 compression spring offers remarkable resistance to fatigue, corrosion, and high - temperature environments. Its advanced manufacturing process, which includes precision coiling and heat - treatment at 850 - 900 °C, guarantees consistent quality and precise dimensions. The spring can withstand cyclic loading up to 1 million cycles without significant degradation, ensuring peak performance even in the harshest conditions. This premium - grade construction reduces the risk of breakdowns and costly repairs, providing long - lasting durability. It also has a corrosion resistance rating that allows it to perform well in environments with up to 50% relative humidity without signs of rust or degradation for over 500 hours.
