Product Specification

original 241-3228 Diesel Fuel Injector for C7 Construction Machinery Spare Part Replacement for OEM new injector original new injector

Engineered exclusively for the C7 and C7 ACERT platforms, this HEUI fuel injector carries the authorized OE reference 241-3228 and serves as a direct replacement unit across 7.2 L inline 6-cylinder configurations rated from 168–224 kW (225–300 hp) at 1800–2200 rpm. The injector integrates seamlessly with the engine's ADEM A4 electronic control module and hydraulically actuated electronically controlled unit injection system, maintaining factory-specified injection timing, atomization characteristics, and rail pressure response. Broad cross-reference coverage including 10R-4763, 241-3400, 328-2585, 328-2582, 387-9428, 238-8091, 222-5958, 233-3535, 236-0974, 295-1410, and EX634763 allows distributors and fleet operators to consolidate inventory against multiple legacy part numbers while preserving engine-specific fitment.

The unit is built for heavy-duty industrial operating environments where C7 engines are deployed, including construction machinery, mining equipment, agricultural power units, generator sets, truck and bus engines, forestry equipment, material handlers, excavators, loaders, cranes, crushers, forklifts, paving equipment, pumps, trenchers, and stationary diesel power systems. Heavy-duty internal construction supports sustained high-load cycles, and each injector can be supplied as new, remanufactured, rebuilt, tested, or replacement condition. Flow testing and leak testing are offered as optional quality verification steps, and calibration trim code verification is performed to confirm cylinder-to-cylinder balance prior to shipment. Supply formats include single piece, six-piece set, or bulk wholesale packaging, with neutral box, brand box, export carton, or pallet configurations available to meet diverse B2B logistics requirements.

Routine maintenance of the C7 fuel system directly extends injector service life and protects downstream engine components. Operators should use clean diesel fuel meeting specifications, replace primary and secondary fuel filters at scheduled intervals, drain water separators regularly, and keep fuel tanks free from contamination. Correct engine oil grade, timely oil filter replacement, and periodic oil sampling support internal component health and early detection of wear or fuel dilution. Diagnostic best practice includes injector leak testing, cylinder cutout testing, ECM fault code scanning, harness and connector inspection, fuel pressure verification, and air system inspection whenever symptoms such as hard starting, rough idle, white or black smoke, misfire, low power, excessive fuel consumption, fuel-in-oil, knocking, or post-replacement smoke appear.
