original 223-5328 Common Rail Fuel Injector Assembly for C10 C12 Diesel Engine Excavator Loader Replacement for OEM 2235328 10R-1003 20R-0055 350-7555 original new injector

Engineered for demanding diesel operations, the 223-5328 Fuel Injector is a precision-built replacement component designed for C12 series engines operating in heavy-duty transportation, construction, mining, marine, and power generation environments. Manufactured to OEM-level tolerances, this injector integrates seamlessly with the Electronic Unit Injection System, delivering reliable high-pressure atomization and consistent metering across the full engine load range. Cross-reference numbers include 2235328, 10R0957, 10R1273, 20R2057, 10R0957RX, 20R2057RX, and CAT2235328, ensuring broad interchangeability for fleet operators and MRO buyers.

Advanced nozzle geometry and superior wear-resistant materials support extended service intervals, while corrosion-protected internal components maintain stable performance under extreme thermal and pressure conditions. Each unit is 100% flow and pressure tested prior to shipment, verifying accurate fuel delivery, improved combustion efficiency, reduced smoke emissions, and better fuel economy. Operators benefit from increased horsepower output, smoother idle, reduced engine vibration, and lower total operating costs. Typical coverage includes a 12-month warranty, making this injector a dependable choice for long-haul trucks, excavators, mining haulers, fishing vessels, prime power gensets, and continuous-duty industrial units.

Correct installation requires disconnecting battery power, cleaning the mounting area, inspecting the cylinder head bore, replacing seals and O-rings, and applying the specified torque sequence. Following OEM maintenance schedules, using clean diesel fuel, replacing filters regularly, and performing injector balance tests will prevent common issues such as hard starting, black or white smoke, rough idle, cylinder imbalance, and elevated emissions.
