Caterpillar original Fuel Injector 11R-0282 for Construction Machinery 5130B 5230B, Cross Reference 20R-1272, Replacement for OEM 392-0211, 20R-0848, fits 3508 C13 C3500 Engines original new injector

The Caterpillar 11R-0282 fuel injector assembly is a high-pressure metering and atomization component for selected CAT 3500 Series diesel engines, including 3512B, 3516B, and 3508B as well as 3512 industrial, marine, generator, and oil & gas configurations. Built to OEM-equivalent specifications, it supports accurate fuel delivery and stable injection pressure in generator sets, marine propulsion and auxiliary systems, mining equipment, offshore platforms, oilfield power systems, compressors, pump drives, and heavy construction equipment.

Its precision fuel delivery technology helps atomize fuel into fine droplets for cleaner mixing with compressed air, supporting efficient combustion, increased power output, lower fuel consumption, and reduced exhaust emissions. The assembly uses corrosion-resistant materials, enhanced wear resistance, and high thermal resistance to sustain reliable performance in demanding industrial, marine, mining, oilfield, and power generation environments, while its long service life can contribute to reduced maintenance costs.

For installation, disconnect the power source, clean the mounting area and injector bore, fit new sealing components, install the 11R-0282 injector using OEM torque values, bleed the fuel system, and verify engine operation. To preserve performance, use high-quality diesel, replace fuel filters regularly, monitor exhaust smoke and fuel consumption, and test injectors during scheduled maintenance. Difficult starting, reduced power, excessive smoke, increased fuel consumption, misfire, rough idle, or vibration may indicate inspection is required. Always verify the engine serial number and application requirements before ordering.
