Thanks, hadn't thought about the clutch adjustment. I have seen old tires come apart on the tire mounting machines, the bead cable had rusted and broke under a very light load. Not trying to argue, just get my head around the belt question. I believe there is no steel in the belt, just various rubber compounds and kevlar cords. Would the answer have been any different if this machine had about 32,000 miles on it now, about 2000 miles a year and had been run every summer? And if the answer remains the same, at about what age should the drive belt be changed, even if in good visual condition?
