Heavy Equipment Parts stocks quality aftermarket alternators for excavators and heavy machinery. A faulty alternator fails to charge the machine’s battery, leading to electrical system failures and unexpected shutdowns on site. Our alternators are remanufactured and new-unit options built to OEM output specifications for reliable charging performance. We supply alternators for Komatsu, Caterpillar, Hitachi, Hyundai, Volvo, Doosan, Kobelco, and other major brands. Available from our Sydney warehouse with fast delivery to customers across Australia.
