original 20R-1269 Fuel Injector Assembly for 3512B 3508B 3516B 3512C 3516C Diesel Engine Excavator Parts ENGINE INJECTOR GP Replacement for OEM 392-0205 3920205 original new injector

Engineered for demanding heavy-duty operations, the 20R-1269 fuel injector serves as a critical fuel delivery component for 3512B and 3516B diesel engines deployed across global industrial, marine, and power generation sectors. This remanufactured unit injector assembly is built to OEM dimensional specifications and cross-references directly with part numbers 10R-0955, 392-0204, and 249-0713, providing operators with a reliable replacement solution for continuous duty applications.

The 20R-1269 delivers precision fuel metering to ensure accurate fuel delivery under varying engine loads, while superior atomization produces optimal spray patterns for complete combustion and improved fuel economy. Heat-treated internal components provide exceptional wear resistance for extended service life, and protective surface treatment enhances corrosion resistance for marine and offshore environments. Designed for 24/7 generator and industrial engine operation, this injector supports high-pressure fuel injection performance in 3512B-HD, 3512B Marine, 3512B Offshore, 3512B Industrial, and 3516B power units.

Global applications include United States power generation, Canadian and Australian mining operations, Middle East oil and gas platforms, African generator rental fleets, Southeast Asia marine propulsion systems, South American construction machinery, and European industrial power installations. Installation requires part number verification, engine serial confirmation, injector bore inspection, replacement of sealing washers, OEM torque application, fuel line connection, leak inspection, and a final engine test run for optimal performance.
