Yeah, that could be it. Looks like just an idler pulley. Easy to change. Just take the belt off, take off the bolt in the center of the pulley, and swap the pulley. By the looks of it, you'd have to do it with a regular wrench. Not sure on the size though. Probably a 13mm or something close.
Can you identify the pulley using the image below?
