Designed for demanding heavy-duty diesel operating conditions, the Caterpillar (CAT) 222-5966 is an industrial-grade HEUI diesel fuel injector purpose-built for selected CAT 3126 Series, 3126B, 3126E, and C7 engine platforms. As a core component of CAT’s HEUI fuel injection system, it delivers precise fuel metering and optimized atomization to support stable injection response, consistent combustion, and reliable engine performance across variable load scenarios. It installs in the engine cylinder head fuel system, with most inline 6-cylinder applications requiring 6 injectors per full set.
This injector is indexed under multiple part number formats across OEM, remanufacturing, and aftermarket supply chains. Its primary non-hyphenated search alias is 2225966, with an associated CAT Reman part number 10R-0781 (10R0781), plus verified interchange references and CAT-prefix search codes for cross-supply chain lookup. It serves core B2B buyer groups including diesel repair shops, fleet maintenance teams, engine rebuilders, parts distributors, marine service providers, and heavy equipment owners.
Fitment is not universal and must be confirmed before purchase via the engine serial number, original injector part number, engine arrangement number, injector trim code, and ECM calibration, per official Caterpillar guidance. Product condition varies by supplier, with options including new aftermarket, remanufactured, service replacement, and OEM replacement units. Protective packaging includes anti-rust treatment, foam inserts, and sealed fuel ports, while 6–12 month warranty terms and reman core return requirements are set by individual suppliers.
