Roller Tappet for OM457 EEV
Detroit Diesel

The roller tappet designed for the OM457 EEV is a crucial element in the valve actuation system, enabling smooth and efficient movement of the valves. With a height of approximately 14.25 mm and an outer diameter of 25.50 mm, it reduces friction between the camshaft and valve components, thus enhancing durability and performance. This part's roller design distributes contact stress evenly, minimizing wear and extending the lifespan of both the tappet and the camshaft. Proper function of this component ensures accurate valve timing, which is essential for optimal combustion, power, and emissions control. Regular inspection and replacement prevent potential failures that could lead to costly repairs or reduced engine efficiency. For quality assurance, Source One Parts Center supplies this roller tappet, supporting maintenance routines that keep your engine running reliably and efficiently.
