Caterpillar original 0R-1740 Fuel Injector for Cat DISA 3304, 3304B 3306B Diesel Engines, Replacement for OEM 4W-7017, Cross Reference 0R-3418 130-1804 original new injector

Accurate fuel atomization begins at the nozzle, and the CAT 0R-1740 diesel injector nozzle is engineered to perform this terminal function within high-pressure fuel injection systems. It receives fuel from the injection pump, supports accurate injection timing, and distributes finely atomized diesel evenly in the combustion chamber. Consistent spray formation helps promote complete combustion, stable engine operation, power output, fuel economy, and emissions performance. The nozzle is commonly associated with CAT C7, C9, C10, C11, 3126, and ACERT Series engine applications.

Manufactured from high-strength alloy steel and processed with advanced heat treatment, the 0R-1740 is designed for wear resistance, corrosion protection, thermal stability, and long service life in severe operating environments. CNC-machined nozzle holes support optimized spray patterns, while the surface treatment helps protect against sulfur-containing fuels and moisture contamination. Strict dimensional tolerances support direct replacement, consistent injection pressure, and stable fuel distribution. Its stated quality level is OEM Equivalent Industrial Grade.

For parts distributors, engine rebuilders, repair workshops, fleet maintenance providers, and equipment owners, clear number identification simplifies sourcing. Reference numbers include 0R1740, 326-4701, 3264701, 10R-7700, and 10R7700. Equipment applications listed for this nozzle include excavators, wheel loaders, bulldozers, articulated dump trucks, motor graders, industrial generators, mining machinery, marine auxiliary equipment, agricultural equipment, and industrial power units. Part-number and engine verification before ordering is recommended to match the component to the intended fuel-system application.
