original 10R-1265 Diesel Injector 0R-8207 0R-8624 0R-0815 0R-9420 119-3166 174-7526 for 3412E D9R AD45 Dozer Replacement for OEM  original new injector

Engineered exclusively for the 3412 Series, the 10R-1265 fuel injector delivers precise fuel metering and high-pressure atomization to ensure clean, efficient combustion across demanding industrial applications. Its multi-hole nozzle design and direct injection compatibility allow the injector to produce consistent spray patterns at pressures ranging from 1200–1600 bar, supporting optimal power output and fuel economy in generators, excavators, marine engines, and other heavy machinery operating in construction, mining, power generation, and oil and gas sectors.

Manufactured to meet original engineering standards, this injector incorporates durable materials that withstand extreme operating temperatures and pressures. Precision-machined internal components guarantee exact flow rates and spray geometry, which are critical for maintaining stable cylinder pressure, low emissions, and reliable cold-start performance. Each unit undergoes industrial-grade testing to verify response characteristics and sealing integrity, ensuring dependable service in continuous-duty and high-load environments.

The 10R-1265 cross-references with 326-1644 and 3261644, allowing straightforward replacement in existing 3412 fuel systems. Proper installation requires the engine to be off and cooled, removal using OEM torque procedures, installation with new seals and gaskets, and subsequent fuel system bleeding per the 3412 manual. Routine inspection of the spray pattern every 500 operating hours, along with clean fuel filters and verified line pressure, helps sustain long-term injector performance.
