original 20R-3247 Common Rail Fuel Injector Assembly for 3512B 3512C 3516B 3516C C35 Excavator Engine Diesel Injector Replacement OEM 392-0225 original new injector

Engineered for the demanding operating conditions of 3500 Series industrial power units, the 20R-3247 remanufactured diesel fuel injector delivers precision performance for 3512B and 3512C V12 engines with 51.8-liter displacement. This injector assembly is a direct cross-reference to OE numbers 236-9007 and 10R-7075, providing verified interchangeability across power generation, marine propulsion, mining, and oil & gas applications worldwide. Built to OEM quality standards, each unit undergoes industrial-grade manufacturing controls to ensure dimensional accuracy, flow calibration, and long-term reliability under continuous-duty loads.

The 20R-3247 injector features high-durability construction and precision fuel atomization geometry that supports improved combustion efficiency, increased engine power output, and reduced fuel consumption. Operators benefit from lower particulate emissions, stable engine performance, improved throttle response, and extended service life. Correct installation and reliable atomization directly address common field issues such as excessive exhaust smoke, engine knock, cylinder imbalance, fuel leakage, reduced power output, difficult starting, and unstable idle — minimizing unplanned downtime across generator sets, marine vessels, mining fleets, and offshore platforms.

For optimal service life, clean the injector bore thoroughly before installation, inspect fuel lines, replace sealing components, and verify injector seat condition. Maintain performance by using clean diesel fuel, replacing fuel filters regularly, monitoring exhaust smoke levels, conducting periodic injector testing, avoiding water contamination, and maintaining proper fuel pressure across all 3500 Series industrial platforms.
