I have a Case 580 Super M that I am trying to replace the hoses that actuate the extendahoe cylinder. My question is concerning the pin that anchors the piston to the boom. After removing the spring clips from both ends of the pin, the pin still refuses to be tapped out. I have watched the youtube video of this procedure and the pin in the video slides easily in and out. I was wondering if the ends of my pin may be deformed slightly making removal difficult. I didn't want to really pound on it until I knew for sure.
