Product Number: 66057009
The Highway Automotive 66057009 is a 24-volt, 120-amp alternator designed as a direct replacement for Volvo coach and bus applications. Supplied complete with belt pulley, it is built to restore reliable charging output to the vehicle's electrical system across six confirmed Volvo applications. The alternator operates at 24 V with a charging current of 120 A, making it suited to the demanding electrical loads found in heavy-duty passenger vehicles. The pulley is an eight-groove unit, supplied fitted to the alternator, so no additional pulley is required at the point of installation. Fitment covers six Volvo applications, including the Volvo 9700 (engine DH12D), the Volvo B11R (engine D11K), and a range of Volvo B12 variants — B12, B12B, B12M, and B12R — across engine codes TD122FH/FL, TD123ES, D12A420, and D12D380/420. The Volvo B12 series in particular spans multiple body configurations, all sharing compatible engine families. The unit is packaged securely at 260 × 250 × 190 mm and carries a gross weight of 8.50 kg, reflecting the robust construction expected of a commercial-vehicle alternator. Use the fitment selection widget or search the cross-referenced catalogue by machine model to confirm compatibility with your specific vehicle, and every fitment shown is backed by the PartsForMachines Fit Guarantee.
