Genuine Nanyue Fuel Injection Pump B4AD545G-R 13053065 for Weichai TD226B-4 Engine

Brand New, Genuine Nanyue Fuel Injection Pump, model 1000950899 . This high-precision mechanical pump, also identified by part number 1305 3065 and pump series BH4 PN120R, is the original equipment for the Wei chai TD226B-4 diesel engine. The TD226B series, known for its European technical lineage, requires a robust fuel system to maintain its reputation for power and fuel efficiency in construction machinery and generator sets.

As the core of the engine’s combustion system, the 1305 3065 is responsible for delivering pressurized diesel to the cylinders with exacting timing. Because it is a genuine Nanyue assembly, it is built to handle the specific torque requirements of the 4-cylinder turbocharged Wei chai engine. The internal plungers and mechanical governor of the BH4PN120R are precision-matched to ensure stable fuel delivery, even under fluctuating loads common in industrial applications. This level of OE quality helps prevent common issues such as engine hunting or uneven power delivery.

If your Wei chai engine is experiencing hard starts, excessive black smoke, or a decrease in RPM stability, the injection pump may be worn or out of calibration. Replacing the old unit with a brand-new 1000950899 is the most reliable way to restore your engine’s thermal efficiency and protect your investment. Using genuine parts ensures that the fuel atomization remains consistent, which in turn reduces carbon buildup and extends the life of your engine. This pump comes factory-sealed and ready for installation, providing a direct-fit solution for professional mechanics and fleet operators.
