This 24V 140A heavy-duty alternator is engineered for demanding applications across multiple OEM platforms, including Volvo Trucks, International Trucks, Daimler/Van Hool coaches with MTU engines, and Tigercat forestry equipment.
It serves as a direct replacement for a wide range of original units, such as:
Caterpillar 200619, Cummins 5483838, Volvo LN110816,
WAI 8941N, Motorola BLP3311, and Prestolite BLP3312 / BLP3312GH / BLP3317A series.
Manufactured by SANYOU using 100% new components—including high-efficiency diode bridges, oversized bearings, and copper stator windings—this alternator meets or exceeds OEM performance in output stability, thermal resistance, and service life. Its 10-groove design ensures compatibility with standard 10-rib serpentine drive systems.
As pulley type may vary by original installation, confirm pulley configuration and mounting dimensions before ordering.
