Iíd like to rescue an old Yale dial but Iíd like some guidance before I use brut force. In the attached pictures, is the spindle attached to the upper part of the spindle/dial with threads or pressed on (see the space circled in red)? If itís pressed on, should I use a wedge to separate it, clean it off and press it back on with JB Weld or just use a brass hammer to push it together? You canít tell from the picture but itís currently off center.

Thanks!!
