Caterpillar original Common Rail Fuel Injector 392-0219 Cross Reference 246-1854, 386-1771, 10R-7238 Replacement for OEM for Caterpillar 3508C 3512C 3516C Construction Machinery original new injector

Built to meet the demands of continuous-duty industrial power, the Caterpillar 10R-7238 fuel injector is a brand-new, OEM-equivalent diesel injection component engineered for the CAT 3512B engine series. It is compatible with CAT 3512B industrial, generator, marine, offshore, and heavy-duty power unit engines, serving diesel generator sets, mining machinery, oil & gas packages, industrial power systems, construction machinery, and emergency backup generators. The injector cross-references part number 317-7238 and is also identified as 10R7238, simplifying sourcing and replacement.

Within the CAT 3512B fuel injection system, the 10R-7238 operates as a high-pressure fuel metering device. It precisely measures fuel quantity according to engine load, speed, and operating conditions, then transforms liquid diesel into microscopic droplets through precision-engineered spray holes. This optimized atomization promotes complete combustion, delivering smooth idle, stable power output, reduced vibration, and lower fuel consumption, while minimizing black smoke, unburned fuel, carbon deposits, and exhaust emissions.

Manufactured with advanced CNC machining and precision grinding to micron-level tolerances, the injector features industrial-grade corrosion protection through special surface treatment, ensuring long service life in harsh mining, marine, offshore, and power generation environments. It operates reliably across a temperature range of -40°C to +200°C and is designed for extended maintenance intervals. Each unit is supplied in brand-new condition, built to OEM-equivalent quality standards, and backed by a 12-month warranty, making it a dependable replacement solution for critical engine fleets.
