Most CS130 alternators came on serpentine-belt applications. If you want to use a CS130 alternator with a V-belt pulley, the easiest way to remove the pulley is with an impact wrench, using gloves or a belt wrench to grip the pulley. Always lay the alternator horizontally to remove the pulley, as placing the alternator vertically could do internal damage. If you don’t have an impact, the end of the shaft is broached for an Allen wrench. Position the Allen wrench on the bench as shown and loosen the 15⁄16-inch nut with a box-end wrench.
