there might be ajuster nut on one of the pulleys, thats lets you move in or out, or up or down, to get the belt on , and then you put it back to were it was after you have the belt on, to keep it tight, we use belt drive cutters in the park were i work, and thats how some of them work, or sometimes, you might have the belt running the wrong way around the pulleys, this is not hard to get wrong, i have done it lots of times, everything looks different upside down, just recheck everything again,
