This listing features a genuine Common Rail CRCP3 Fuel Diesel Pump, officially designated by the part number 0445020109. Built on the heavy-duty CP3 radial-piston platform, this high-pressure supply unit is a direct replacement for Komatsu OEM 6754-72-1012 and Cummins reference 4989266. It is engineered to maintain a stable high-pressure fuel reservoir, ensuring consistent atomization for modern electronically controlled diesel systems.
The 0 445 020 109 is specifically calibrated for the Komatsu PC200 excavator series and engines using the Cummins ISB QSB (3.9L/5.9L/6.7L) platforms. This pump utilizes a triple-lobe internal cam and durable pumping plungers to generate the sustained rail pressures (up to 1600 bar) necessary for Tier 3 and Stage IIIA emission-compliant operation. Its integrated Fuel Control Actuator (FCA) ensures precise volumetric displacement, allowing the engine to respond instantaneously to the varied hydraulic loads encountered in construction environments.
Replacing an aging supply unit with this factory-sealed Common Rail CRCP3 Fuel Diesel Pump resolves critical engine issues such as hard-starting when hot, sudden power loss under load, and rail pressure deviation codes. Installing this authentic 0 445 020 109 assembly ensures your Komatsu PC200-8 Cummins Engines ISB QSB powertrain maintains its optimal torque curve, fuel efficiency, and long-term uptime during high-intensity earthmoving tasks.
