Product Overview The Caterpillar C10 Series Fuel Injector 233-5327, also searched as 2335327, is an industrial diesel fuel injector designed for heavy duty Caterpillar engine fuel systems, especially applications connected with the CAT C10 diesel engine family and selected C10 / C12 aftermarket injector supply chains. This injector is commonly referenced together with numbers such as 223-5327, 2235327, 229-5918, 2295918, 0R-8773, 0R8773, 10R-1256, and 10R1256 in open aftermarket diesel injector listings and remanufactured injector databases. Public Caterpillar parts information confirms 223-5327 as a Cat fuel injector group and lists 10R-1256 as a reman fuel nozzle / injector product number; Cat also emphasizes that fuel injectors deliver the correct fuel amount at the correct time and that compatibility should be checked against the machine or engine configuration. This product page is structured for professional industrial buyers, repair shops, diesel engine rebuilders, fleet maintenance teams, construction equipment parts distributors, and global aftermarket customers who need a clear, searchable, database-style product description. The injector is positioned as a replacement / aftermarket / reman-compatible reference product, not as a guaranteed universal fitment for every engine unless verified by engine serial number, injector calibration code, equipment model, and service manual. The 233-5327 fuel injector is used in the fuel delivery system of a diesel engine. Its core function is to control the quantity, timing, atomization, and spray pattern of diesel fuel entering the combustion chamber. Correct fuel injection performance is essential for engine starting, idle stability, torque output, fuel economy, exhaust smoke control, emission performance, and long-term engine durability. For B2B product publishing, this page intentionally includes multiple versions of the same part numbers with and without hyphens, because industrial buyers search in different formats. A customer may search 233-5327, 2335327, CAT 2335327 injector, C10 injector 223-5327, 229-5918 fuel injector, 0R8773 injector, or 10R1256 reman injector. Including these variants improves Google SEO coverage, AI search retrieval, product matching, and internal website search performance.
