Scav air valves on a 500

Recommended Posts

Very common problem and a little pricy, We use ACF 50 every 100Hrs to prevent the corrosion from building up and seizing the poppet. Hot air and mositure from the compressor will seize it every time. Works well once you start to lube them. Or if it’s stuck closed you can use a bolt and thread it into the poppet to knock it out and clean it up... If you have any more questions feel free to call us. Phoenix Heliparts, Mesa AZ 480-985-7994
