Engineered for demanding diesel power systems, the 321-0990 Common Rail Fuel Injector Assembly delivers OEM-grade injection performance across C6, C6.4, and C6.6 engine platforms. This electronic-controlled injector supports high-pressure common rail operation exceeding 1800 bar, providing accurate atomization for cleaner combustion, stronger engine output, and reduced exhaust emissions. Cross-referenced part numbers include 10R-7220, 326-1641, 326-1642, 387-9433, 2645A746, 2645A747, 320-0680, 320-0677, and 295-1411, ensuring broad interchange coverage for global fleet operators and rebuilders.
Manufactured with micron-level precision and hardened alloy steel components, the injector body offers exceptional durability under continuous heavy-load cycles. Advanced surface treatment resists fuel contamination, moisture exposure, oxidation, and sulfur corrosion, while thermal stability from -40°C to +120°C secures reliable cold starting and hot-climate operation. Expected service life ranges from 5,000 to 10,000 operating hours under proper maintenance, making this component ideal for hydraulic excavators, wheel loaders, bulldozers, motor graders, generator sets, marine propulsion units, and mining equipment.
Designed for worldwide industrial deployment, this injector serves construction fleets in North America, mining operations in South America, Africa, and Australia, oilfield equipment in the Middle East, infrastructure projects in Europe, and marine and palm oil applications throughout Southeast Asia. Proper installation requires clean sealing surfaces, new copper washers, correct torque specification, fuel priming, and injector trim coding where applicable.
