It took a lot of doing and 4 hands to get the pin out of the handle but I got the thing apart and greased and it's like a brand new valve. I was going to replace the spider gasket because the pool level seems to be dropping, but I took the hose off the discharge line and there isn't any water coming out of it. Maybe it is a sometime problem. I hope it isn't something more serious because there are no obvious leaks. At any rate thanks for the response. That problem is solved.
