I have done it. Take the hand wheel off. You will see two large screws that were hidden behind the hand wheel. Remove these screws. The whole motor/ bobbin-winder assembly will then slide off in one piece. You may have to rocks it to get it off. All you have to do it to now slide on a spoked hand wheel. The only problem in this is you don't have a bobbinwinder. But after market combo of bobbin winder and hand wheel cover/ hood is available. I usually have these and they are inexpensive. Here is a picture of one.
