The only part that would be replaceable would be the bearing for the pulley itself, and this would require drilling out some rivets and reassembling with bolts (unless you can find appropriate sized rivets and installation tool). The bearing is a standard part - part number is something like 6203??? Don't recall for sure. Just know it's got a "6" in it and some alpha identifiers at the end. How's that for help?
In any case, it sounds like you're describing a problem with the spring tensioning portion of the assembly, which as far as I know, is not something you can fix.
