This listing features a high-grade CB28 Common Rail Fuel Injection Pump, officially identified by the part number 0445025602 . Engineered for modern heavy-duty commercial vehicles, this high-pressure mechanical unit serves as an exact replacement for the OEM reference J20001111100A38. It is designed to generate the extreme hydraulic rail pressures required for precise electronic fuel metering and optimal combustion phasing.
The 0445025602 assembly is specifically calibrated for high-displacement YUCHAI Diesel Engine platforms, which are widely utilized in heavy trucks, transit buses, and industrial machinery. Utilizing advanced CB28 high-pressure pumping architecture, it ensures consistent volumetric delivery across a wide RPM range. The hardened internal plungers and reinforced drive shaft are manufactured to withstand the severe cyclic loading and abrasive wear common in demanding commercial operations, maximizing torque backup under heavy payloads.
A failing high-pressure supply unit often leads to severe power derating, extended cranking, or low rail-pressure fault codes. Replacing a worn assembly with this factory-sealed CB28 Common Rail Fuel Injection Pump eliminates internal bypass leakage and restores the specific flow characteristics demanded by the YUCHAI Diesel Engine control module (ECM). Proper installation guarantees reliable heavy-duty operation, stable idling, and strict compliance with modern commercial emission standards.
