Mine also broke at about 50 hours. I had the dealer replace it that time. Now at 200 hours it broke again. I bought the belt at the dealer, for like 30 bucks so at least it was cheap. I can NOT get the damn thing on. I have it just like the dealer told me. I have routed it every way possible and it lacks about 3/4 of an inch from going over the 3rd pulley, no matter what order I try it. It's very frustrating. Anyone have any tips?
