The other day I received a letter from my cousin telling me of his experiences replacing a drivebelt on a rooftop air conditioner on his church. The old belt was marked A-40 so to be on the safe side he bought a A-40-1/2. It was way too tight so he got an A-41. Still too tight so he had to move the motor. I remember having similar belt problems years ago but I'm wondering why belt manufacturers havn't been able to standardize their length measuring system? Engineman1
