    Hi everyone. I'm trying to do a little maintenance on a u-7, and I can't seem to get it apart. I've taken off the screw at the bottom of the motor, and the two set screws inside the top of the motor, and I just can't get the bell off. There is a small piece of metal in there I need to take out, and I can't tell if I need a press or what trick I need to separate the bottom of the motor from the bell.

    Any tips or advice?

    Thanks as always.

    Steve

    it's been awhile but isn't there a spring clip on the shaft on the bottom of the motor? Not sure about the U7 but most motors are made this way.

    Yeah, it had a screw in the bottom. Here is a picture to show you... I don't see any clip ring...

    I've tried making a makeshift press out of a few screws and plates, I've tried tapping on the center post there (gently)... tried prying and pulling and no movement on the bell at all. I'm kinda stumped... I took the set screws out of the top inner shaft... and it seems like I should be able to pull it apart... but nothing on the web to show me how to take the thing apart.

    Looks like the bearing might have been hot/cold pressed into the housing, perhaps, Steven?

    That would make sense Andy... Thanks... Bummer, I don't have the tools to undo that. :(
