Well, I think I have found a solution for my seal problem. For the others that might be interested,I found a new style seal that fits tight on the shaft but a little loose in the casting. I put the shaft in the unit fit the seal over the shaft and set set the seal in with J-B weld, then verily easily pulled the shaft out. Not much movement going on there or heat so I think it will work. The seal is a Federal Mogul #252277 wish me luck, just need to stop the grease leak.
