Valve Rocker Arm 14441-Z0J-000

This is an exhaust valve rocker arm used for small engines and equipment like pressure washers. Rocker arms transmit motion from a camshaft to valves, controlling valve timing and duration. If your engine struggles to start, misfires, or will not start, inspect the rocker arm(s) for excess play, wear, or bending due to high temperatures. To replace it, disconnect the spark plug and/or starting coil, remove the valve cover, and locate the rocker arm(s). Rotate the camshaft until pistons are up and rocker arms are loose. Slide out the pin, remove the old rocker arm, and install the new one with its pin. Tighten the adjustment screw to the manufacturer specifications, reinstall the spark plug, replace valve cover sealant, and reattach the cover.
