Exhaust Valve Spring for OM457 EEV
Detroit Diesel

This exhaust valve spring is engineered to maintain consistent tension on the exhaust valve, ensuring proper valve closure during engine cycles. Its precise dimensions, including a free length of 69.70 mm and wire diameter of 4.20 mm, are designed to withstand extreme thermal and mechanical stresses typical of OM457 engines. The spring’s inner and outer diameters are calibrated to provide reliable seating and prevent valve float, which can lead to engine misfires or damage. Proper valve spring performance is crucial for maintaining optimal combustion timing, reducing emissions, and ensuring smooth engine operation. High-quality materials and manufacturing standards enhance durability, preventing fatigue and failure over extensive service periods. Regular inspection and replacement of worn springs are vital to avoid engine performance issues.
