Caterpillar original 241-3238 Common Rail Fuel Injector 243-4502 for Excavator Construction Machinery C7 Engine Replacement for OEM 387-9426, 268-1836 original new injector

As a genuine OEM-grade Hydraulically Actuated Electronically Controlled Unit Injector (HEUI) purpose-built for Caterpillar diesel powertrains, the 241-3238 fuel injector delivers factory-matched performance for specified C7 engine platforms. It is fully compatible with CAT C7, C7 ACERT, C7.1, industrial C7 and power generation C7 engines, and is developed in strict adherence to Caterpillar’s original engineering specifications to ensure seamless fit and consistent, factory-spec operation.

The injector leverages HEUI technology to amplify engine oil pressure and multiply fuel pressure to over 20,000 PSI under electronic control of the engine control module (ECM), enabling precise fuel metering, optimal atomization and thorough, efficient combustion. These design features deliver tangible operational benefits including improved fuel economy, reduced emissions, enhanced cold-start performance, increased power output and reliable long-term service in harsh industrial operating conditions. It fits a wide range of equipment including excavators, wheel loaders, motor graders, mining machinery, generator sets, industrial power units, construction machinery and heavy-duty trucks across construction, mining, power generation and freight sectors.

For simplified cross-platform replacement, the 241-3238 injector supports direct interchange with a comprehensive list of OEM, remanufactured and aftermarket reference numbers for global diesel injection systems. Every unit undergoes 100% factory testing to verify calibration, high-pressure performance and corrosion resistance, and comes with a 12-month warranty for B2B customers serving regional equipment maintenance, repair and overhaul markets worldwide.
