Belt Identification
Drive belts are marked on there outside with the width and circumference
of the belt. The older type numbering system used the letters
A, B, C and D for the width and a X after the first letter means
that the belt is a cog belt. The circumference is a two digit
number. The new system of numbering utilises 3L, 3V, 3VX, 4L,
5L, 5V, 5VX etc with a three digit number which is the circumference
in millimeters. E.g. a belt labeled AX-36 is a cogged
belt with a circumference of 36 inches.
