Engineered for Caterpillar's C9 diesel platform, the 20R-8427 fuel injector assembly is one of the most critical components in the engine's fuel system. It delivers precisely atomized diesel fuel into the combustion chamber at controlled timing and quantity, directly supporting stable power output and fuel efficiency. Identified in Caterpillar's official parts listing as a Cat Reman injector, it is purpose-built for professional engine repair, overhaul, and injector replacement programs.
The injector is matched to the CAT C9 industrial diesel engine, an 8.8-liter inline six-cylinder unit with a 112 mm bore and 149 mm stroke, rated approximately 205–280 bkW (275–375 bhp) at 1800–2200 rpm and meeting China Stage III, EPA Tier 3 equivalent, and EU Stage IIIA equivalent emission standards. Typical installations include excavators, loaders, bulldozers and graders, mining support machinery, diesel generator sets, pumps, compressors, and CAT C9-powered truck platforms, covering construction, mining, power generation, and industrial applications.
For sourcing flexibility, the 20R-8427 crosses to 387-9435, 20R-1959, CA20R8427, CA3879435, and CA20R1959 across OE and aftermarket channels. Because fitment varies by engine arrangement, buyers should confirm compatibility using the engine serial number, machine model, and original injector code before ordering. Condition options include new replacement, remanufactured replacement, and original reman type units, making the 20R-8427 a practical choice for diesel repair distributors, parts dealers, rebuilders, and fleet maintenance companies worldwide.
