Perkins original Perkins 0R-8475 Mechanical Diesel Fuel Injector Pump Assembly for 3114 3116 3126 Engine Replacement for OEM new injector original new injector

The Perkins 0R-8475 remanufactured fuel injector is engineered to deliver consistent and precisely metered diesel fuel for the Perkins 3116 and Perkins 3114 engine families. Featuring a 7mm specification with a 0.195 orifice, this unit injector supports high-pressure injection, stable combustion, and reliable power output across demanding industrial operating conditions. It is commonly specified for the Perkins 3116, 6.6L inline-six, four-stroke turbocharged-aftercooled diesel engine with mechanical governor, and is also compatible with the Perkins 3114 engine family. Confirmed equipment references include the CB-434 and CS-531 vibratory compactors, and aftermarket listings frequently associate this injector with additional compactor models such as CP-563 and CS-563.

Built to Perkins Reman quality standards, the 0R-8475 provides accurate fuel atomization and controlled injection timing, contributing to smooth idle, efficient fuel consumption, and reduced exhaust emissions. The injector cross-references to 0R-8475, 0R8475, OR-8475, OR8475, 127-8207, 1278207, and 127 8207, making it a direct-fit replacement for engine rebuilding, scheduled maintenance, and emergency repair. It is suitable for road construction equipment, industrial diesel power units, fleet machinery, marine service, mining, quarrying, generator and power-unit service, and global spare parts distribution. The injector is offered as a single replacement unit or as a full six-cylinder engine matched set for high-hour engines requiring balanced fuel delivery.

Proper installation and routine maintenance are essential for maximum injector service life. Operators should maintain clean fuel, replace fuel filters at the correct service interval, and drain the water separator regularly to prevent contamination-related wear. When the injector is removed, technicians should inspect the injector sleeve, seals, and bore, and confirm correct engine timing and injector synchronization. Monitoring exhaust smoke, engine oil for fuel dilution, and fuel consumption by machine hours helps identify developing injector issues such as hard starting, rough idle, misfire, black or white smoke, low power, high fuel consumption, or diesel knock. Diagnostic procedures include fuel pressure testing, cylinder balance testing, and inspection of the air and fuel delivery system to ensure consistent performance and long-term reliability.
