    Need some pictures. Belt adjustment is normally fairly easy. Get some light and look it over good. Loosen up motor mounting bolts and slide is how most work.

    I'm sure there is a way to replace the fan belt. I know this because that fan belt was not manufactured at the same location as the fan blades or the fan motor, or even the pulleys for that matter. But they were all put together at the same place. I bet if you remove enough nuts, bolts and screws, you will be able to get a new belt on that fan assembly

    After you make that expensive repair and you still have the same problem, What will you check next?
