In my experience the sump screen is always broken in the flat area. I don't think I ever seen one broken in the corrugated area. This latest 650 is no different. After cleaning everything in solvent, I removed the broken screen. There is a raised edge around the frame left over from the manufacturing process. Using a fine file, I cleaned up the edges making them flat as possible. I used a piece of .020 aluminum stock and formed it to match the shape of the frames and JB Welded it in place.
