This valve guide for the OM457 EEV engine’s constant throttle system is made from gray cast iron, combining wear resistance with thermal stability. Its length of 34 mm and bore diameter of 8.06 mm ensure precise alignment within the cylinder head, guiding the intake or exhaust valve accurately during operation. The outer diameter of 13 mm provides a secure fit, minimizing movement and ensuring consistent valve seating. Proper valve guide function is vital for maintaining valve alignment, preventing oil leaks, and ensuring smooth valve operation. This component's material choice offers excellent longevity even under high temperature and stress conditions, which are typical in heavy-duty engines. Regular maintenance and timely replacement of worn guides are essential for sustained engine performance and emission compliance.
