original 179-6020 Diesel Engine Fuel Injector for 3412 3408 3126 Engine Truck Injection Valves Auto Parts Replacement OEM 1796020 171-9710 original new injector

Engineered for demanding industrial diesel platforms, this heavy-duty fuel injector assembly (OE 179-6020, cross reference 20R-0760) is a direct replacement component designed for 3126, 3126B and 3126E engine series, as well as 3408C, 3408E, 3412E and E3412 power units. Built to OEM-level specifications, it delivers precision fuel metering, stable combustion and reliable cold-start performance across construction, mining, marine and power generation applications.

Manufactured from precision alloy steel with hardened internal components and corrosion-resistant surfaces, the injector withstands high-pressure HEUI operation and continuous-duty cycles typical of mining haul trucks, quarry equipment, bulldozers, wheel loaders and industrial generator sets. Precision-machined nozzles ensure accurate spray patterns for reduced fuel consumption, improved torque output and lower exhaust emissions. Verified fitment covers heavy equipment platforms such as D9R, 769D, 771D, 773D, 775D, 631G and 637G, plus marine workboats, tugboats and prime/standby generator engines.

Supplied as a direct-replacement assembly with a 12-month warranty, this injector simplifies fleet maintenance and reduces downtime. Recommended service includes daily inspection for leakage and idle stability, weekly checks on fuel filters, pressure and seals, and scheduled cleaning, flushing and performance testing. Installation follows standard OEM torque specifications, system bleeding and electrical harness reconnection procedures, ensuring long service life and consistent output in off-highway vehicles and industrial power systems.
