The motor might need a bit of care (cleaning, regreasing, replacing wicks and checking carbon brushes) but they often come around by just letting them run a bit. I would clean the pulley and hand wheel (paying extra attention to the grooves), and double check for oil spill on the new belt too. The V-belts are quite narrow and fit's in its' groove rather accurately. As long as it does and you can tighten the belt it should be fine; correct fit is when it runs rather loosely on the pulley; there should be a bit of give in the belt, not too tight.
