Engineered for Caterpillar C7 and C9 engine platforms, the 172-5780 diesel fuel injector is an original-quality electronic unit injector built to OEM-level tolerances. It interchanges directly with a wide range of part numbers—including 1725780, 235-2888, 235-9649, 188-8739, 217-2570, 236-0962, 10R-7224 and CA1725780—making sourcing straightforward for distributors, repair shops and fleet operators. Verified applications cover 330C, 330C L and 330C FM excavators, the D6R II tractor, 973C loader, TK711/721/722 and MT735/MT745 machines, plus industrial generator sets.
In operation, the injector works within a high-pressure, electronically controlled fuel injection system. The Engine Control Module (ECM) signals the solenoid to open with precise timing, delivering accurately metered fuel through multi-hole nozzle tips. The resulting ultra-fine atomization mixes thoroughly with compressed air, supporting complete combustion, maximum torque output and lower emissions. Manufactured from high-strength alloy steel, the assembly pairs heavy-duty construction with superior fuel atomization, reducing fuel consumption and enhancing engine performance under demanding duty cycles.
For B2B buyers, the 172-5780 delivers OEM fit and function backed by a 12-month warranty and long service life proven in construction and mining operations. It serves construction equipment, mining machinery, agricultural equipment, industrial power units, generator sets, earthmoving and material handling applications. Multiple cross references, large inventory availability, fast installation and international shipping support help lower operating costs and simplify global procurement for both new and reman programs.
