The belt will probably need to be replaced but I noticed that the lowest wheel/rotater/what have you is about 1/2 an inch further out towards the wheel then the other wheels/rotaters/what have yous. In other words, it is not paralelle with the other wheels. I can put the belt back on with some pretty good tension however it will eventually fall off inwards considering it is riding on the edge of the rotater. Please go here if you need a diagram. http://www.cargurus.com/images/2008/05/21/22/37/pic-19983.gif . The larger wheel in the middle bottom of the picture is the one that is about a 1/2 inch outward compaired to the other wheels. The belt eventually falls off the track of that wheel into a little crevase... *sigh*. Any clue on if this wheel/rotater should be more "inward" and paralelle with the other wheels/rotaters?
