I have a Kenmore Ken Cart model 116.732. I'm wanting to find out if I can retrofit an old Electrolux model XXX motor to fit, as the fans look like an Electrolux model XXX's fans. The top fan has a nut that I'm unable to remove, I've tried heating it up with a heating gun and using an air ratchet to no avail. The body is in good shape and I don't really want to throw it away. Thank you for your help
