    Trick to removing impeller from shaft seal?!!

    We are endeavoring to replace our pool pump motor ourselves but cannot get the impeller off of the old pump. Is there a trick to this? We are holding the shaft end in place while trying to turn the impeller to the right to "untwist" it. However, we can't seem to get a good enough hold on the impeller to put a lot of strength into the turning of it without putting too much stress on the impeller...I'm thinking that we don't want to hurt the impeller...

    Any advice would be greatly appreciated! Thank you!!

    I like to use a strap wrench. It is gentle on the impeller but sometimes they are virtually welded on there.

    Good luck with it.

    Honestly I took mine to the pool shop and they removed it for me.

    While there I bought the new shaft seal from them.

    I then took it home and put the new motor on it and got it all up and running.

    The impeller turns to the left not to the right. If there is a screw in the impeller that turns to the right to loosen. So that is the problem.

    My impeller removed itself when the pump found out I abandoned it and ordered a new energy efficient one. The day after I placed my order, the impeller broke/burned right off the shaft. I don't suggest this method as my new pump is still on its week-long journey accross the country.
