7940-7100: 16-19mm (3/4) Wide Belt Conversion Pulley

Some agricultural, industrial, and marine applications run a particularly wide V belt. When replacing original generators or alternators with the 10SI Series One Wire Alternators, it is necessary to match the belt width along with the need for increased rpm of the alternator at slow engine speeds. Our part number 7940-7100 accomplishes the small diameter pulley along with the width that the 16-19mm (3/4) belt needs. These come with a special collared hex nut needed to work with the pulley.
