Perkins original Perkins 198-6877 Common Rail Fuel Injector Assembly for 3412 3412E 3408 Engine D9R 637G new injector original new injector

Engineered specifically for the Perkins 3412 V12 diesel platform, the 198-6877 fuel injector delivers precise atomization and consistent fuel metering across demanding industrial duty cycles. With a multi-hole nozzle design producing a 155° spray angle, it ensures complete combustion chamber coverage while supporting an operating pressure range of 2000–2500 bar. The unit cross-references to 9W-8895 and 184-4412, making it a reliable substitute for service operations involving 3412, 3412 DITA, and 3412 E series engines rated from 425–605 HP, 450–625 HP, and 500–625 HP respectively. Heavy-duty steel construction provides exceptional resistance to thermal stress and mechanical wear, extending service life under high-load conditions found in generators, construction machinery, and marine propulsion systems.

This injector is manufactured to meet original equipment specifications for spray pattern, flow rate, and pressure tolerance, supporting compliance with EPA and EU emissions standards. Direct mount installation simplifies replacement procedures, reducing equipment downtime for fleet operators and service workshops. The component is compatible with a broad range of vehicles and equipment, including heavy machinery, mining vehicles, construction equipment, marine engines, and industrial generator sets powered by the Perkins 3412 series.

Routine maintenance is essential to sustain optimal injector performance. Operators should inspect the unit every 500 hours of operation, clean the nozzle tips using approved industrial solvents, and conduct fuel system diagnostics to identify leaks or misfires. Seals and O-rings should be replaced during scheduled service intervals to preserve injection integrity. With its precision engineering, robust construction, and full compatibility with the 3412 engine family, the 198-6877 injector provides a dependable solution for B2B buyers seeking OEM-grade reliability in heavy-duty diesel applications.
