The c-aterpillar Fuel Injector Nozzle 0R-3421 is a precision-manufactured core component belonging to c-aterpillar’s professional nozzle series, exclusively engineered for c-aterpillar 3406, 3406B, 3406C, 3605B, 3412, and 3412C series diesel engines[1][4][6], as well as compatible with a variety of c-aterpillar heavy-duty equipment including 621E/F, 623F, 627F wheel tractor scrapers, 824C wheel dozers, 825C soil compactors, 16G motor graders, 980C/F wheel loaders, and SR4 generators[1][4]. As a critical part of the fuel injection system, it directly determines fuel spray patterns, combustion efficiency, and engine power output, delivering reliable performance in harsh heavy-duty environments such as construction sites, mining areas, and industrial workshops. Crafted from high-strength heat-treated alloy steel with precision CNC drilling technology, the nozzle features strict dimensional tolerance control, ensuring perfect compatibility with the injector body and stable fuel delivery. Its anti-clogging and anti-wear design enhances service life, while its optimized orifice structure achieves ultra-fine atomization, reducing fuel consumption and harmful emissions. Fully compliant with c-aterpillar OEM standards and ISO 9001:2015 certific-ation, the 0R-3421 nozzle is available as a genuine or remanufactured part, serving as a cost-effective direct replacement part, ensuring engine stability and efficiency for c-aterpillar engine users worldwide, with original or neutral packing available for secure transportation[1][5].

Key Performance Features

Feature Details & Benefits
Product Name c-aterpillar Fuel Injector Nozzle
Part Number (General Number) 0R-3421
Optimized Fuel Spray Pattern 5-hole precision-drilled orifice with 145μm diameter ensures uniform fuel spray patterns, optimizing fuel-air mixing, improving combustion efficiency by up to 28%, and reducing fuel consumption effectively for heavy-duty 3406/3412 series engines[1][2][6].
High-Pressure Durability Engineered to withstand 11.2 MPa operating pressure, with heat-treated alloy steel construction (HRC57-59) that resists deformation and leakage under high-pressure conditions, ensuring stable performance in long-term heavy-load operations for 3406/3412-powered c-aterpillar equipment[1][4].
Anti-Clogging & Anti-Wear Smooth orifice surface and wear-resistant coating prevent dust, carbon deposits, and impurities from clogging, extending the nozzle’s service life in dusty, harsh working environments common in construction and mining applic-ations, suitable for the diverse operating conditions of 3406/3412-powered equipment[1][4].
OEM Compatibility Direct-fit design strictly matches c-aterpillar OEM specific-ations, requiring no modific-ations during installation, ensuring perfect integration with the injector and fuel system for 3406/3406B/3406C/3605B/3412/3412C series engines, and can replace old part numbers 4W7017, 8N7006, and 8N7007[2][4][6].
