This rocker arm adjuster, or valve lash adjuster, is a genuine OEM replacement part used in lawn tractors. It is approximately one inch long and made of steel. It is responsible for adjusting the clearance between the rocker arm and valve stem, which allows the valves to open and close as needed. The adjuster will need to be replaced if the threads are stripped, or if it is cracked, or worn down. Remove the spark plug wire to prevent accidental starting and remove the valve cover from the engine to access the rocker arm. Detach the rocker arm and unthread the faulty adjuster. Screw the new adjuster into the rocker arm and use a feeler gauge to set the correct intake clearance. Reinstall the arm into the engine and return the valve cover to complete the repair.
