If there's nothing wrong with the sewing head, and all you need is a clutch motor, by all means get the right one and go for it. Have the machine checked out by a sewing machine pro before you do anything. He can tell you if it's worth buying a motor for it. I have two clutch motors, one brand new, and one older one I'm going to put on E-bay, but if you send me a private message, I'll sell you whichever one you want, or both. They will both work fine on the Singer 111W type machines. I just replaced both my clutch motors with servo motors.
