original 11R-0282 Diesel Fuel Injector for 3508 3512 3516 3524 C13 Engine Replacement for OEM 392-0211 20R-1272 20R-1274 Construction Machinery Parts original new injector

Engineered to meet the demanding operating requirements of large-bore industrial diesel engines, the 11R-0282 Fuel Injector is a precision-manufactured replacement unit designed for 3512B, 3516B, and 3508B power units. This injector assembly is fully interchangeable with cross-reference numbers 11R0282, 0R-8477, 0R8477, CAT11R0282, and CAT0R8477, delivering OEM-equivalent form, fit, and function for global service, maintenance, and overhaul programs.

Built using corrosion-resistant materials and high thermal-resistance components, the 11R-0282 injector provides precision fuel delivery, stable injection pressure, and enhanced wear resistance for extended service life under continuous heavy-duty operation. Key performance benefits include improved combustion efficiency, increased engine power output, lower fuel consumption, reduced exhaust emissions, and enhanced overall engine reliability. Typical applications include diesel generator sets serving data centers, hospitals, and utility backup systems; marine propulsion and auxiliary engines on cargo ships, tugboats, and offshore support vessels; mining haul trucks, excavators, and drilling equipment; oil & gas drilling rigs, fracturing units, and gas compression stations; plus industrial compressor packages and pump drives.

Proper maintenance ensures optimum performance: use high-quality diesel fuel, replace fuel filters on schedule, and monitor exhaust smoke and fuel consumption. When installing the 11R-0282, disconnect power, clean the injector bore, fit new sealing components, apply OEM torque values, bleed the fuel system, and verify engine operation. Common symptoms indicating injector replacement include difficult starting, reduced power, excessive smoke, engine misfire, rough idle, and vibration.
