Mitsubishi 34368-01100 is the alternator with a double groove V belt pulley, a cooling fan, two mounting ears and a rear terminal connector. It is used on Caterpillar E320B and E320C excavators. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.
