The Caterpillar 0R-8475 Cat Reman fuel injector is a remanufactured diesel unit injector engineered for the Caterpillar 3116 inline-six, 6.6L turbocharged-aftercooled diesel engine and the related 3114 engine family. Featuring a 7mm body and a 0.195 orifice, this injector delivers accurate fuel metering, stable high-pressure injection, and consistent combustion for reliable power output under demanding industrial operating conditions. It is designed as a direct replacement for OE 0R-8475 and cross reference 127-8207, supporting use on CB-434 and CS-531 vibratory compactors, with aftermarket associations to CP-563 and CS-563 units that should be confirmed by serial number.

This injector is intended for engine-machine platforms, paving compactors, road construction equipment, industrial diesel power units, and heavy-duty fleet machinery. It can be supplied as a single replacement unit or as a complete matched set of six injectors for high-hour engine rebuilds. Related service items for installation and overhaul include the 6V-6228 O-ring, 119-2940 gasket, 119-3061 injector sleeve, 032-8970 FKM O-ring, and the 1R-0750 secondary fuel filter, supporting a complete fuel system service.

Reliable operation depends on fuel cleanliness, correct filtration, regular water separator draining, and proper installation following the Caterpillar service manual. After fitting, technicians should verify injector synchronization, fuel setting, fuel timing, and valve clearance to maintain engine performance and emissions compliance.
