Tappet clearance, also known as valve clearance, is the small gap between the rocker arm and the top of the valve stem (Yoke). Engineers can observe and adjust tappet clearance only when the valves are in a closed position and the engine is cooled at the compression stroke.
What is tappet clearance and how should you properly adjust it based on the engine’s needs? When talking about ship engines, this is one of the few issues that will come up sooner or later. Hence, it is an important skill for any engineer that will eventually troubleshoot engine problems.
In this article we delve into the basics of measuring, and adjusting tappet clearance to solve common engine issues on ships. After reading this post you should have a better idea of what tappet clearance is and why it’s important
