Ordered and replaced belt tension pulley and dryer belt. The repair was almost the same as the video except if you replace the pulley only, not the pulley and bracket unit. Snap ring pliers will be needed and the reinstall of the pulley and belt, with the tub in place, was not as easy as in the video. I would do it again but would order the pulley and bracket together as the shaft for mounting the pulley had some tarnish or corrosion on it and it may reappear. Time will tell.
