The Caterpillar 10R-0781 HEUI fuel injector is engineered for CAT 3126, 3126B, 3126E and C7 7.2L inline-six medium-duty diesel engines. It operates within the Hydraulic Electronic Unit Injector fuel system, where the engine ECM precisely controls injection timing and duration while high-pressure engine oil supplies the hydraulic force required for fuel pressurization. This electronically managed actuation supports optimized cold starting, warm-up behavior, combustion quality, emissions output, fuel economy, engine noise and overall drivability across demanding on-highway and off-highway duty cycles.
This injector carries OE specification 10R-0781 and cross references 197-7107, 198-6605, 199-6065, 222-5966, 222-5926, EX630781, CA10R0781, CA1977107, CA1986605, CA1996065 and CA2225966, giving distributors, workshops and fleet operators strong searchability across multiple CAT 3126- and C7-related repair markets. It is designed for medium-duty trucks, buses, school buses, RVs, marine vessels, fire trucks, cranes, construction equipment and industrial power units, with vehicle compatibility including Freightliner, Ford, GM, International, Kenworth and Western Star. C7 applications further extend to agriculture, compressors, drilling, crushing, forestry, forklifts, hydraulic power units, irrigation, mining, paving, pumps and trenchers. A complete six-cylinder engine service requires six injectors, and units are also sold individually.
Because HEUI injectors rely on engine oil to generate injection actuation pressure, long-term performance depends on clean fuel, clean oil, correct filtration, stable electrical signals and proper HEUI oil pressure. Before installation, confirm the removed injector number, inspect the injector bore and sleeve, and replace all sealing components. After installation, prime the engine, check for leaks and complete a diagnostic scan following official Caterpillar service procedures for torque values, ECM programming and test routines.
