During routine maitenance on my pump today, I was changing out all the o-rings and gaskets, shaft seal, ect. I put the pump back together and started up the pump/filter. About 3 minutes into running, heard bang inside my pump. Tore the pump down again and discovered that the impeller had seperated from the shaft. Now my question is how do I get the remaining piece off the shaft. I have held the one end with a wrench but I cannot get enough leverage to turn the old remaining brass fitting off. Any suggestions.
Thank you in advance.
