SPM-HEP-4747 is the 24 volt, 35 amp alternator with a double V belt pulley, cooling fan, aluminium housings and an integrated vacuum pump on the rear end. It is used on Mitsubishi 6D31 engines. 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.
It replaces Mitsubishi ME070120 and Mitsubishi ME087508.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.
