Caterpillar original For Caterpillar HEUI Fuel Injector 179-9380, replacement for OEM 20R-4147, compatible with D10R D9R cross reference 20R-4148 10R-0781, diesel engine spare original new injector

Precision-engineered for demanding Caterpillar 3412 Series diesel engine platforms, the 179-9380 fuel injector assembly is a critical fuel injection component built to sustain consistent engine performance across heavy-duty industrial operating conditions. As an OEM-equivalent replacement part, it delivers precisely metered, high-pressure diesel fuel to engine combustion chambers at factory-calibrated intervals, supporting optimal air-fuel mixing and reliable, efficient combustion initiation. It is compatible with all core 3412 series variants, including 3412B, 3412C and 3412D, as well as marine, generator set and industrial power unit configurations.

Every 179-9380 injector features a precision-machined injector nozzle and OEM-calibrated fuel flow, with corrosion-resistant internal components engineered to withstand continuous high-pressure fuel system operation. These design attributes enable precise fuel atomization, enhanced combustion efficiency, improved fuel economy, reduced exhaust emissions, smoother engine operation with lower vibration, and improved cold-start performance. Its industrial-grade build also extends overall engine service life, cutting unplanned downtime and long-term operational costs for end users.

This versatile component supports equipment across six core industrial sectors: power generation, marine, mining, oil and gas, construction, and industrial power systems, with common use cases ranging from backup generator sets and marine vessels to mining trucks and oilfield hardware. Each unit undergoes 100% quality inspection prior to shipment, is packed in export-standard packaging, and has a minimum order quantity of 1 piece, suiting both spare parts distributors and in-house equipment maintenance teams.
