original 173-9267 Fuel Injector for 3412 3412E 3126B 3512B Diesel Engine 5110B Common Rail Injector Diesel Engine Parts Replacement OEM 1739267 173-9268 original new injector

Engineered as a direct OEM-equivalent replacement, the 173-9267 diesel fuel injector delivers precision-metered fuel delivery for 3412, 3412B, and 3412C turbocharged diesel engines used across demanding industrial and marine platforms. Cross-referenced with 0R-8686, 10R-0957, and 10R-0958, this injector assembly is manufactured to strict dimensional and hydraulic tolerances, ensuring seamless installation into the cylinder head and consistent atomization performance across the full operating range of high-output diesel power units.

This heavy-duty injector features precision fuel atomization, high-pressure capability, corrosion-resistant construction, and an extended service life designed to withstand continuous-duty operation. Key performance functions include accurate fuel metering, precise injection timing, and a uniform spray pattern that improves combustion efficiency, reduces fuel consumption, and lowers exhaust emissions while enhancing engine power output. Typical deployments include emergency generator sets, prime power stations, data center backup systems, cargo vessels, offshore support vessels, haul trucks, mining generators, drilling rigs, gas compression units, and large earthmoving equipment.

Each unit is supplied new with a 12-month warranty and industrial export packaging suitable for global logistics. Recommended maintenance includes high-quality diesel fuel, regular filter replacement, and scheduled injector testing. Diagnostic support covers fuel pressure testing, injector balance tests, leak-off tests, nozzle spray pattern analysis, and electronic engine verification for reliable long-term operation.
