Richard,the beveling of the outer edge as Peanut has recommended can be done with a Dremal tool.You just want to use your finger and feel for a sharp edge,put a 45 degree angle on that edge until you don't feel scraping with your finger.I would install the new seal with out push rod in,by hand with gasket sealer on outside,lube the push rod before installing it.
