This alternator is engineered for Scania P450, R450, R500 and R580 vehicles equipped with the DC13143, DC13148, DC13146 12.7L engines and the DC16102 16.4L engine platform from 2016 onward. It replaces multiple OEM references including Mitsubishi A004TR6791, A004TR6791A, A004TR6791AM, A004TR6791ZT, A004TRG891AM, as well as Scania 2191880, 2395911, 2398370, 570889 and 579274.
Configured as a 24V 130A alternator with a 10-groove 70 mm pulley, it is produced with fully new components to deliver stable charging output for heavy-duty trucks operating under demanding conditions. The alternator structure aligns with the operating requirements of Scania Euro 6 engine systems, supporting continuous electrical loads associated with long-distance transport, auxiliary equipment, and modern electronic modules.
The internal rectifier, regulator, and stator assembly is manufactured to provide consistent current output and maintain voltage stability under varying engine speeds. The high-capacity rotor and bearing arrangement is designed for steady operation on large commercial vehicles that experience long running hours, highway driving cycles, and temperature fluctuations.
This alternator is built with mounting dimensions and electrical interfaces that match the original Scania configuration, allowing direct installation on DC13 and DC16 series engines. Its load-response characteristics and heat-resistant insulation materials contribute to dependable performance across extended operating periods.
Manufactured by SANYOU, the alternator is produced to meet or exceed the functional requirements of the OEM references it replaces. Its performance characteristics and service life are consistent with original factory units, providing reliable power support for Scania heavy-duty vehicles in transportation and logistics operations.
