    For sure you can use a 13.9mm pulley on a 14mm belt. It is done all the time but you cannot use a 14mm pulley on a 13.9mm belt. The 14mm pulley will eat up a 13.9mm belt.

    Belts

    Are there many 13.9 belts out there? I thought that it was just about all 14mm anymore

    there is only one belt length that is 13.9, the rest are 14MM, also 13.9 is a htd tooth profile, there are HTD and GT profiles in 14 MM
