Motor Re-Wire to reverse spin

Post by seminaryfleming »

Hello!

I have an old Shopsmith Mark V Greenie (Gilmer Belted) that is slowly dying of some abuse (before my time, but it looks like it got banged around as multiple parts have suffered metal stress fractures including spindles, casing, mountings, and bearings.) I want to rescue the bandsaw and motor and just use the two stand-alone. So I pulled the motor out of the shopsmith and also the bandsaw. I would like to line up the motor directly behind the bandsaw to save width as my shop is tiny. This means reversing the spin of the motor from its original direction. I don't know what wires I need to swap to make this happen. I have attached pictures to the post to show the motor opened up. It is a Franklin Electric C995A2 3/4HP 3450RPM motor. As far as I know it is original to the unit.

Even if I end up not being able to reverse the motor, I need to re-attach the cabling which I removed at the switch without thinking. All of it is black wires, so I don't know even which ones to plug in to where.

Any help would be much appreciated.

(As an aside, I have the jointer, sanding disk, and ways/stand portions of the shopsmith I'd be willing to give away if you can get them near Dubuque IA.)

The start circuit consists of the start winding in series with the start switch and start capacitor. The ends of that series circuit attaches to the run windings and power cord. Reversing the start circuit end connections will cause the motor to run in the opposite direction.

However there appears to be a start circuit and run winding internal(inaccessible) connection. :>{
