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

The Caterpillar CAT 192-2817 is a genuine new fuel injector assembly engineered exclusively for the CAT 3512B diesel engine platform, part of Caterpillar’s 3500 Series. Built to strict original OEM specifications for electronic unit injection systems, it is compatible with all 3512B variants configured for generator sets, heavy-duty mining, marine propulsion, offshore oil and gas, industrial power, and continuous-duty prime power generation applications.

Constructed from high-strength alloy steel with corrosion-resistant, wear-resistant components and industrial-grade sealing, the injector features precision-machined nozzles, OEM calibration, high-pressure tolerance, and robust thermal stability. It delivers precisely metered, finely atomized fuel to optimize combustion efficiency, reduce fuel consumption and particulate emissions, boost power density, stabilize power output, improve cold-start performance, and extend overall engine service life even under harsh, high-demand operating conditions.

This injector supports a wide range of mission-critical equipment across power generation, marine, mining, and oil and gas sectors. It comes with a 12-month warranty, and proper installation requires OEM number verification, injector bore cleaning, seal/O-ring replacement, fuel line inspection, torque verification, leak testing, fuel pressure testing, injector calibration checks, and ECM diagnostic scanning. Routine daily maintenance includes fuel leakage inspection to sustain long-term reliable performance and reduce unplanned downtime for industrial operators.
