original 246-1854 229-1631 204-2067 192-2817 0R-3539 Diesel Common Rail Fuel Injector for C3500 3512B new injector original new injector

Engineered as a direct-fit replacement for 3500 series platforms, this OEM-spec fuel injector 246-1854 delivers factory-calibrated atomization for the 3512B and 3516B diesel engines. The assembly is fully compatible with 3512B, 3516B, 3508B, 3512, 3516, and 3508 engines, including all 3500 Series industrial variants. Cross-referenced to 2461854, 10R-7224, 10R7224, 249-0713, and 2490713, it provides a reliable service replacement for diesel generator sets, marine propulsion units, mining trucks, oil and gas power modules, and continuous-duty power stations operating under sustained high-load conditions.

Manufactured to OEM precision tolerances and 100% flow tested prior to shipment, this injector assembly maintains stable injection pressure, enhanced combustion efficiency, and consistent fuel metering across long duty cycles. Its corrosion-resistant internal components and hardened nozzle tip are built to withstand extreme industrial environments, reduce smoke emissions, and lower cylinder-to-cylinder temperature variation. The result is improved fuel economy, stable engine power output, and extended engine service life, even in remote mining, marine, and oilfield installations where downtime is costly.

Installation should follow the official service manual, with fuel system calibration performed when required. Operators are advised to use only approved diesel fuel, install genuine OEM fuel filters, and replace all O-rings and sealing washers during fitment. Care must be taken to prevent contamination of the nozzle or fuel passages. Routine monitoring of exhaust smoke, periodic fuel pressure testing, and maintaining a clean fuel supply will help preserve injector performance and prevent common issues such as hard starting, power loss, rough operation, and excessive emissions on 3512B, 3516B, and 3508B engine applications.
