Perkins original Perkins 20R-0849 Reman Fuel Injector for 3508 3512 3516 3524 C13 Diesel Engine Construction Machinery new injector original new injector

The Perkins 20R-0849 fuel injector is a genuine OEM-spec replacement component engineered for the Perkins 3500 Series engine platform, including the 3408, 3412, 3512B, 3512C, 3516, 3516B, and 3516C models. Designed for heavy-duty continuous-duty operation, this remanufactured injector delivers precise fuel metering and optimized atomization to improve combustion efficiency, enhance fuel economy, and reduce exhaust emissions across generator sets, marine vessels, mining trucks, oilfield equipment, and industrial power plant applications.

Built to meet stringent Perkins fuel system requirements, the 20R-0849 injector features durable internal components and tight manufacturing tolerances that ensure consistent injection performance under high-load and high-temperature conditions. Its robust construction supports stable cylinder pressure, balanced fuel delivery, and reliable cold-start capability, making it suitable for critical standby power systems in data centers, hospitals, and emergency backup installations where downtime is not an option.

Before installation, technicians should verify the injector part number against the engine serial number, inspect the injector bore, replace all sealing components, clean the fuel lines, and confirm adequate fuel pressure and filtration. Installation must follow Perkins torque specifications using approved tooling, with calibration performed where required. After installation, a leak inspection, engine performance check, exhaust quality verification, and fuel consumption monitoring are recommended to ensure optimal operation.
