The Caterpillar CAT 3116 3114 mechanical unit fuel injector 0R-8473 is a remanufactured replacement designed for CAT 3114 and CAT 3116 MUI diesel engines. Featuring an 8 mm diameter nozzle and a dual scroll design, this injector is engineered to match original equipment performance for industrial, truck, construction, and power generation applications. It is cylinder head mounted and intended for mechanical unit injection systems, not for modern common rail setups.
This reman fuel injector delivers precise fuel quantity control, stable injection timing, and consistent cylinder-to-cylinder fuel balance. The optimized spray atomization reduces smoke and incomplete combustion, while improving cold starting, acceleration response, and fuel economy under load. It also helps protect the piston crown from overheating caused by degraded spray patterns, supporting longer engine life in heavy-duty service environments.
Compatible with multiple interchange numbers including 127-8213, 101-8673, 0R-4374, 0R-3382, and 4P-1734, the 0R-8473 serves the engine service, repair, remanufacturing, and replacement markets. It is suitable for fleet maintenance operations, diesel engine rebuilding, and wholesale parts distribution where reliable CAT 3114 and CAT 3116 fuel injection components are required.
