The Automatic Timing Lock for Caterpillar engines simplifies TDC valve/injection timing by providing a spring-loaded pin that can be easily engaged and disengaged. The tool is ideal when working on the engine in-situ or when the specialized turning tool is unavailable or unable to be used. Removes the need for an assistant to acquire TDC and begin valve and fuel injection timing procedures.
