Can you tell me what the belt looks like? is the new belt the same as the old one . i just bought a 750 it works ok but the belt is cracked and has what looks like a connector that splices 
it together. It is a v type belt. Could you look at yours real close and let me know if your belts are the same or if this one has been patched.        I  dont see a problem in replacing it, will let you know how its done with pics or video
