Greetings to all, I decided to do maintenance on my kick up rudder and it has been impossible for me to remove my old 3/8 pintles from the casting to replace them with new 1/2 pintles. I have tried everything, penetrating oil, hammer blows, even a tie rod extractor tool and nothing, it does not move. any technique or trick to remove it? I would appreciate any answer that helps me, thanks.
