The engine is spinning clockwise. So the outer race should spin free counterclockwise so the belt won't turn. Think of it this way. If the engine was running and you grabbed the bearing's outer race...the part the belt sits on, that's doing the same thing as the engine stopped and you turn that race counterclockwise. So it should spin free counterclockwise. It's in backwards.
If it was the sheaves contacting the belt was the problem, first you would gauge the gap between the two to ensure its; below spec. Then you would check the shims and/or other parts that end up giving it that set distance between the two sheaves.
