original 0R-8785 Fuel Injector Nozzle 7W-7026 9Y0818 7W-7031 Common Rail Fuel Valve Nozzle for 3406 3406B 3406C 3408 3412 3412C Excavator Diesel Engine original new injector

Engineered for heavy-duty diesel platforms, the 0R-8785 Fuel Injector Nozzle Assembly delivers precision fuel atomization and dependable long-cycle performance across demanding industrial environments. Designed as a direct replacement carrying cross references 0R8785, 7W7031, 7W-7031 and R-7W-7031, this nozzle assembly is manufactured to OEM equivalent geometry, ensuring plug-and-play compatibility with 3406B, 3406C, 3412C and SR4 generator engine platforms used in construction, mining, marine, and stationary power applications.

Each unit is CNC machined from hardened alloy steel and finished to micron-level internal tolerances, producing uniform spray distribution, stable injection pressure and enhanced combustion efficiency. Hardened internal components and anti-corrosion treatment extend service life under continuous-duty loads, while optimized fuel delivery reduces consumption, lowers exhaust emissions and improves thermal efficiency. The result is a stable, repeatable injection event that helps prevent black or white smoke, hard starting, rough idle and power loss commonly associated with worn nozzles.

Suitable for excavators, bulldozers, wheel loaders, mining trucks, offshore service vessels, prime power gensets, compressor and pump drives, and continuous process equipment, the 0R-8785 is a trusted maintenance solution for OEMs, fleet operators and aftermarket distributors. Supplied with 12-month warranty coverage and neutral industrial packaging, it is available for bulk B2B export and long-term supply partnerships.
