If it was my machine, I would go to Sears' website, look for parts link, enter your model number to find the parts page that includes the belt and you will likely see the arrangement of things well enough to do the job yourself.
Their parts pages are invaluable for this kind of research and have been helpful in the repair of many Sears/Kenmore/Craftsman products.
