These are a standard US belt. I think it is the .200" pitch belts. Bring
the pulley to any belt and bearing house and they will immediately recognize
the system. If you have the number of teeth on each sprocket and the
distance between shafts, they have a calculator that can figure belt length.
McMaster-Carr also has this calculator on-line on their web site.
