Followed instructions for replacing this belt as it was only a belt and did not come with instructions on how to do it! Is working. The belts seem to rub at the point of contact with the vacuum and I am confident that the belts and parts were put on and reattached in the correct order and location and then installed correctly in the correct locations. Eventually it had to wear out and then the whining noise of that belt snapping inside went away after about 2 weeks, at least when the vacuum was used about 3 days a week for maybe 20 minutes of work a day.
