The Perkins Reman Fuel Injector carries the authorized OE number 0R-8475 and is engineered as a direct replacement for the Perkins 3116 inline-six, 6.6L turbocharged-aftercooled diesel engine, also fitting the Perkins 3114 engine family. Verified cross references include 0R-8475, OR-8475, 0R8475, OR8475, 127-8207, 1278207, 6V-6228, 119-2940, 119-3061, 032-8970, and 1R-0750, supporting accurate part identification across global distribution channels and aftermarket catalogs.

Designed with a 7mm specification and 0.195 orifice, this unit injector delivers controlled high-pressure fuel metering, stable combustion, and consistent power output under industrial operating loads. It is confirmed for use in Perkins machine engine arrangements and vibratory compactor models including CB-434, CS-531, CP-563, and CS-563, covering road construction equipment, paving machinery, fleet maintenance, marine service, mining, quarrying, and generator or power-unit applications. The injector is available as a single replacement unit or as a complete six-cylinder matched set.

Service life depends on fuel cleanliness, filtration condition, water separation, correct installation, and overall engine condition. Operators should follow scheduled fuel filter replacement intervals, drain the water separator regularly, and inspect injector sleeves, seals, and bores during removal. Diagnostic indicators such as hard starting, rough idle, black or white smoke, misfire, low power, elevated fuel consumption, diesel knock, fuel leakage, high exhaust temperature, or fuel dilution in engine oil should prompt fuel pressure testing, cylinder balance testing, injector synchronization, and timing verification. Final fitment must be confirmed by engine serial number and machine arrangement number.
