there are 2 belts on 04 model 1 is narrow 1is wider, the narrow one can be replaced quite easily, but it is the other belt that causes problem this belt stretches quite easily and will not turn roller if you have clutch out, check pulley that the wide belt goes around if any damage to pulley you must replace clutch, some dealers are selling this wide belt ( not gen dyson) I do not think this belt can be bought from dyson. if there is a loud clicky noise when vac is running,this clutch will have to be replaced also check, there is no damage to brush roller, as this can clutch to wear out. clutch is £22 feel free to e-mail jonsemple@talktalk.net
