This worked very well but it takes time to undo the screws under the yellow plastic case. They look like the yellow plastic covering them can be removed, but they aren't. I used a drill and an exacto knife to pry out the molded plastic covering the screw holes, wondering if I had messed up my vacuum. I don't think it's intended to replace a belt. But once the screws were undone I followed the YouTube video and some instructions in the Revain comments and it installed smoothly and works very well. Once you know you'll have to drill through the plastic to get to the screws, it's doable. The price of the belt was very reasonable.
