Engine Valve Spring for OM457 EEV
Detroit Diesel

This valve spring is engineered to maintain consistent tension on the engine’s intake or exhaust valves, ensuring they open and close at precise timings during each cycle. Its specific dimensions—such as a free length of 73.60 mm and a wire diameter of 4.35 mm—are chosen to withstand the high stresses of the engine’s valve train, resisting fatigue and deformation over extensive service hours. The inner diameter of 24.70 mm and outer diameter of 33.40 mm provide a perfect fit within the valve assembly, contributing to stable valve operation. The compressed length of 35.25 mm indicates its ability to return to shape after each cycle, maintaining proper valve clearance. This spring’s strength and durability are crucial for preventing valve float at high RPMs, thus protecting the engine from potential damage.
