I recently replaced the impeller and seals on my Pentair Ultraflow pump. The only seal I didn't replace was the shaft seal, which of course, is now leaking. I skipped it because I could not get it out of the seal plate and I could not get the seal plate off of the motor. Prying only bent/crushed the baffling on back and I didn't want to crack it. Does anyone have any suggestions as to how to get the seal plate off or shaft seal out of the plate?
