Roller Tappet
Detroit Diesel

The roller tappet is a pivotal component in the valve train, translating camshaft rotation into linear motion to operate the engine’s valves. With a length of approximately 74.35 mm and an outer diameter of 32.65 mm, it is built to withstand the repetitive forces of high-performance engines. The roller surface reduces friction between the camshaft and valve components, leading to quieter operation and less wear. Properly functioning tappets are essential for maintaining accurate valve timing, which directly impacts engine efficiency and power. Regular inspection and precise adjustment are necessary to prevent misfires and ensure optimal performance. When selecting reliable tappets for heavy-duty engines, Source One Parts Center offers durable, high-quality solutions designed for longevity and consistent operation in demanding environments.
