Product Introduction
The VG1246090015 alternator is a heavy-duty charging system component designed for trucks equipped with MC13 diesel engines. It provides reliable electrical power generation for vehicle lighting systems, electronic control units, air conditioning systems, and battery charging under demanding operating conditions.
This alternator is widely used on SINOTRUK SITRAK C7H, SITRAK G7, and SITRAK G7H heavy-duty trucks powered by MC13 series engines. The MC13 platform features a 12.4L inline six-cylinder diesel engine with power outputs ranging from 500HP to 540HP, making it a popular choice for long-haul logistics and heavy transport applications.
Manufactured with high-strength aluminum housing, precision copper windings, and advanced silicon rectification technology, the VG1246090015 alternator delivers stable voltage output, excellent heat dissipation, and long service life. It is engineered as a direct OEM replacement part to ensure easy installation and reliable performance.
The SITRAK C7H and G7 series have gained significant market share in Russia and Eastern Europe due to their high payload capacity, fuel efficiency, and competitive operating costs. The VG1246090015 alternator is therefore an important aftermarket replacement component for fleet operators and distributors in these regions.
