I have searched this forum but was not able to find the proper way to remove the front crank plug for constant speed prop. I have a new Lycoming IO-390 with the supplied manuals and all I can find is it needs to be removed.
I recall mention of drilling a small hole in the center and securing a small bolt or screw and pull on that. I'm not liking drilling due to the chips. Tapping or applying a screw will make more.
I also recall or at least I think I recall someone mentioning using the ball side of a hammer and hitting the hammer with another , caving in the plug loosening it. How solid is this plug? Is it like a frost plug on industrial engines, if so I do believe that is how they are removed.
Thanks Ron
