impeller removal

Hi,

I am looking for information on removing an impeller form my pump motor. I need to replace the seal and slinger. My question is is the impeller a rt or lt hand thread and does anyone have any tricks for getting it off. I have tried having someone hold a large screwdriver at the one end and using a socket on the impeller formed acorn nut but have been unable to remove it. I don't want to have to destroy it and buy a new one.


Thanks for any help

Spa pumps (http://www.hottubworks.com/SpaParts/PumpsLanding.php) will normally have a right hand thread. So when you remove the back plate on the motor and use a screw driver in the slot you would want to turn the screwdriver to the left and the impeller in the opposite direction. Unfortunately it is not uncommon to break a impeller (http://www.hottubworks.com/SpaParts/PumpParts.php) when trying to remove. You can get rust built up on the shaft and will freeze the impeller onto it.
