I used a dremil on mine and the middle shaft will get hot if you touch it with the cutting wheel when you are cutting away the housing off of the side of the hull! And the whole thing pull right out! I moved the hole and used them again, and used a 2 part epoxy called plastic fustion to re-attach them to the new spot on the sie of the hull! Now when I was cutting the housing I could feel the cutting wheel hitting the center pin or axle and I just made sure I hit it some and not cut into it, just touched it enough to create some heat on the shaft to remove it!
