original 20R-3247 Engine Injector Common Rail Assembly for 3516C 3512C C35 3508B Excavator Spare Part original new injector

Engineered exclusively for the 3512B and 3512C diesel platforms, this remanufactured fuel injector assembly carries the primary OE designation 20R-3247 and is fully interchangeable with 236-9007 and 10R-7075 reference numbers. Built to OEM quality standards, the injector integrates directly with the fuel system found on 51.8-liter V12 configurations, ensuring consistent fuel delivery, precise atomization, and stable combustion across the entire 3500 Series engine family.

Each unit is remanufactured under industrial-grade processes that restore internal components to original performance specifications, supporting improved combustion efficiency, increased power output, reduced fuel consumption, and lower particulate emissions. The robust construction is validated for heavy-duty continuous operation, delivering enhanced reliability, faster engine response, and extended service life for demanding applications such as power generation, marine propulsion, mining haul trucks, oil and gas operations, and heavy construction equipment.

Prior to installation, the injector bore should be thoroughly cleaned, sealing components replaced, and the injector seat condition verified in accordance with service procedures. A post-installation leak inspection is required. For long-term reliability, operators should use clean diesel fuel, replace fuel filters at scheduled intervals, monitor exhaust smoke levels, perform periodic injector testing, avoid water contamination, and maintain proper fuel pressure to prevent common issues such as cylinder imbalance, engine knock, excessive exhaust smoke, fuel leakage, reduced power output, increased fuel consumption, difficult starting, and unstable idle.
