original 20R-0056 Diesel Fuel Injector for C15 C18 Engine Excavator Engineering Machinery Common Rail Injector Replacement 212-3463 10R-0967 original new injector

Engineered for the demanding operational profiles of heavy-duty diesel platforms, this remanufactured fuel injector—identified by primary OE reference 20R-0056—is a direct-fit replacement for C10 and C12 series engines, including C12 ATAAC, C12 Marine, and C12 Generator configurations. It also supports 3176 and 3196 engine variants, offering cross compatibility with 350-7555, 170-5252, 203-7685, and 10R-1268 part references for streamlined procurement across mixed fleets.

Manufactured to strict dimensional tolerances, the injector is constructed from hardened steel and wear-resistant materials, with surface-treated components that resist corrosion from fuel contaminants and prolonged environmental exposure. Its optimized nozzle geometry delivers superior atomization, promoting improved fuel-air mixing, more complete combustion, and stable fuel delivery across varying engine loads and speeds. Operators benefit from increased horsepower output, reduced particulate emissions, better thermal efficiency, lower fuel consumption, and enhanced throttle response—critical performance factors for continuous-duty industrial service.

Typical deployments include 345B, 345B II, 365B, and 365B II excavators, 725 and 730 articulated trucks, 972G II wheel loaders, R1600G underground mining loaders, and MT835 through MT865 agricultural tractors. The injector is equally suited to marine propulsion, auxiliary marine engines, generator sets, emergency backup power systems, compressor drives, and field service engines within oil and gas operations, delivering OEM-level reliability across construction, mining, agricultural, and power generation industries.
