The Caterpillar 7C-4175 fuel injector is engineered as a direct OEM replacement for CAT 3500 Series engines, covering the 3512A, 3512B, 3516, and 3508 platforms. Manufactured to original equipment specifications, it carries cross references to 0R-2924, 6I-4356, 7C-0345, OR-2411, 4P-9075, 4P-9076, 4P-9077, 111-3718, 127-8220, and 61-3075, allowing seamless substitution across the Caterpillar fuel injector family without modification.

Constructed from hardened alloy steel with factory-calibrated nozzle geometry, the 7C-4175 delivers optimized fuel atomization, accurate spray pattern, and stable injection pressure under all load conditions. The corrosion-resistant body and precision-machined internal components ensure consistent combustion efficiency, reduced exhaust emissions, and reliable engine power output across marine propulsion, power generation, mining haul trucks, construction machinery, and oil and gas installations operating in harsh environments.

Each injector is supplied in OEM or export-grade packaging with a 12 to 24 month warranty and is available in new or remanufactured condition. Recommended maintenance includes fuel filter inspection every 250 hours, injector testing at 1000 hours, fuel system cleaning at 3000 hours, and full injector overhaul at 6000 hours. During installation, the fuel system should be cleaned, all seals, o-rings, and gaskets replaced, OEM torque specifications followed, fuel lines inspected for contamination, and calibration verified after fitment.
