    Replacing a motor


    I am looking to replace my AO Smith motor (I think the bearings are gone - it's making a weird noise AND I broke the starter switch when investigating). I have one question - seems kinda stupid, but how do I get the diffuser off the drive shaft? The whole thing turns (obviously) but when I try and hold the shaft at the other end with a screw driver I just can't free it - is there some sort of trick I'm not trying?

    I'm also assuming the loud noise is the motor - I don't see what else it could be.........?

    Once I get the Diffuser/Impaller off, is it pretty simply to switch in the new motor - just looks like a rewire and then replace the parts?

    The shaft is likely left hand threaded...which way have been turning it?
