Caterpillar original Caterpillar 4P9076 fuel injector new injector original new injector

The CAT 4P9076 fuel injector is a genuine OEM replacement component designed for the Caterpillar 3512A V12 diesel engine platform and compatible with the 3508, 3508B, 3512, 3512B, 3516, and 3516B engine series. This high-pressure mechanical injector delivers precisely atomized fuel into the combustion chamber at calibrated timing, supporting stable engine operation across generator sets, marine propulsion systems, oilfield equipment, and heavy mining machinery including the D11N, D11R, 777B, 777C, 785, 789, 992C, 992D, and 994 models.

Manufactured to original equipment specifications, the 4P9076 injector features a precision-machined nozzle, OEM-calibrated flow rates, heavy-duty corrosion-resistant construction, and 100% factory performance testing. Cross-referenced with part numbers 0R-9076, 0R2921, OR2921, 7E3382, 9Y1785, 0R2836, CA4P9076, and CAT4P9076, this unit provides improved fuel economy, increased engine power output, reduced smoke emissions, enhanced cold-start capability, and extended service life. It carries a 12-month warranty and meets strict industrial-grade quality standards.

Routine maintenance of the 4P9076 injector includes the use of clean diesel fuel, regular fuel filter replacement, periodic injector flow and spray pattern inspection, and exhaust condition monitoring. Recommended diagnostic procedures cover the Injector Balance Test, Fuel Pressure Test, Cylinder Cut-Out Test, and Fuel Contamination Analysis. Common fault symptoms such as black smoke, hard starting, or excessive fuel consumption can typically be resolved through bench testing and replacement of the worn injector assembly, restoring reliable engine performance in demanding power generation, marine, mining, and oilfield operating environments.
