Caterpillar original Caterpillar 192-2817 Common Rail Diesel Fuel Injector 0R-3539 for 5130 5230 Excavator Spare Parts new injector original new injector

The Caterpillar CAT 192-2817 fuel injector assembly is engineered as a direct OEM equivalent replacement for the CAT 3512B diesel engine, part of the CAT 3500 Series. Manufactured from high strength alloy steel with corrosion resistant and wear resistant materials, this Electronic Unit Injector (EUI) is designed to deliver stable fuel metering and consistent atomization under high pressure conditions. The thermal stability design and industrial grade sealing ensure reliable operation across demanding duty cycles, including prime power generation, continuous duty operation, and heavy-load applications. Each unit is calibrated to OEM specifications to support improved combustion efficiency, reduced fuel consumption, higher power density, and lower particulate emissions.

This injector is compatible with a wide range of CAT 3512B-powered equipment, including generator sets, standby and prime power units, data center and hospital backup systems, marine propulsion engines, offshore supply vessels, tug boats, commercial cargo ships, fishing vessels, mining power modules, heavy haul mining equipment, open pit mining operations, drilling rig power units, offshore platforms, compressor stations, fracturing equipment, and remote energy facilities. Cross references include 192-2817, 1922817, CAT1922817, CAT-192-2817, Caterpillar 1922817, Caterpillar 192-2817, 10R0955, 10R1271, 10R1273, 10R7222, 10R7224, 10R7672, 1278216, 2123467, 2490713, 3264700, and 3282574, supporting easy identification and replacement across global parts inventories.

For optimal installation, technicians should verify the OEM number, clean the injector bore, replace seals and O-rings, inspect fuel lines, perform torque verification, conduct leak and fuel pressure tests, complete injector calibration, and run an ECM diagnostic scan. Routine inspection covers fuel leakage, engine idle quality, abnormal smoke, fuel filter condition, fuel pressure, injector connections, injector balance, atomization quality, and harness integrity. Major service intervals include bench flow testing, spray pattern analysis, internal wear inspection, and complete fuel system calibration to maintain engine stability, better cold-start performance, and extended engine service life.
