Perkins original 155-8723 Diesel Engine Common Rail Fuel Injector for  3126 3126B 10R-0782 196-1401 4CR0197  original new injector

The Perkins 3126 Series Fuel Injector 155-8723 is engineered as a direct OEM replacement for Perkins 3126, 3126B, 3126E, and C7 diesel engines equipped with the HEUI (Hydraulic Electronic Unit Injection) fuel system. Designed to operate at 1350–1600 bar, this electronic unit injector delivers precision fuel metering and fine atomization through a multi-hole nozzle spray pattern, ensuring optimized combustion across medium-duty trucks, vocational and service vehicles, excavators, wheel loaders, backhoe loaders, compactors, industrial power units, diesel generator sets, agricultural equipment, and mining support machinery. Vertical direct injection orientation maintains factory combustion geometry for reliable engine performance.

Manufactured from high-grade steel alloy with corrosion-resistant surface treatment, the injector features precision-machined components that withstand high thermal and mechanical stress over extended service intervals. Each unit undergoes quality-controlled assembly and technical verification to meet OE-certified performance standards for Perkins 3126 platforms. Installation-ready numbering, engine-specific compatibility, and batch supply options support efficient inventory management for fleet maintenance programs, diesel repair shops, and global distribution channels across North America, Europe, Asia, Australia, South America, the Middle East, and Africa.

The injector is cross-referenced with 0R-8742, 0R-8743, 20R-5392, 169-7408, 178-6342, 111-7916, 0R-9350, 173-9272, 196-1401, 218-4109, 128-6601, 4CR0197, 232-1167, 222-5972, 2C0273, 153-5938, 155-1819, 20R-0758, 232-1171, Bosch 0445110130, and Delphi 9308-621C, providing broad interchangeability for replacement-ready applications. For dependable operation, injectors should be inspected every 500 operating hours, with regular fuel filter replacement, water separator draining, oil filter maintenance, and matched-set replacement when ECM diagnostic codes, hard starting, excessive black or white smoke, rough idle, power loss, or fuel knock are detected.
