Go get a small wood screw that is long. Drill two small holes in the seal opposite each other. (Just large enough to help start the screw.) Run the screw in, being careful not to bottom it on the alum housing. Then, take a pair of needle nose pliers, grip the screw right at the seal and pry against the housing. Alternate sides. Sometimes, you don't even need two screws. They usually just pop out! Every now and again, this method doesn't work. But you'll have it apart, so if you have to you can pull the pin. I've changed the seal on the right side like this many times. Good luck!
