Valve Cone Keeper Half for OM457 EEV
Detroit Diesel

The valve keeper cone half is a critical securing component designed to lock the valve spring retainer in place on the valve stem. With a height of 9.70 mm, it provides a precise fit that prevents spring or retainer slippage, ensuring reliable valve operation during engine cycles. Made from high-strength steel, this cone half withstands the intense stresses and thermal cycles within the cylinder head, contributing to safe and stable valve seating. Proper engagement of this part ensures that the valve assembly remains intact under high pressure and vibration, reducing the risk of catastrophic engine failure. Its steel construction offers excellent durability, resisting wear over many miles of operation. Source One Parts Center recommends this part to ensure the longevity and safety of the valve train assembly in heavy-duty engine applications.
