Diesel Fuel Injector 328-2580 10r-9003 Common Rail Injector for Cater-pillar Cat C9 Excavator

F

This heavy-duty diesel engine electronic common rail injector (OE part number: 328-2580, corresponding Reman remanufactured part number: 20R-2284) is a top-tier fuel supply core component calibrated for ultra-high pressure fuel systems. Specifically designed for Cater-pillar C9 series high-power heavy-duty diesel engines, it is perfectly compatible with Caterp-illar 330D and 336D series tracked excavators, D6R and D6T series heavy-duty bulldozers, as well as 966H and 972H series wheel loaders and high-power industrial mobile power stations. As the central control point for fuel atomization quality, it incorporates micron-level hydraulic servo needle valves and high-speed electromagnetic response technology, specifically designed for harsh working conditions involving high dust, uninterrupted operation, and extreme loads. When your core machinery is equipped with this brand-new high-precision injector, the overall performance will undergo a significant transformation: the previous problems of difficult cold starts and severe engine vibration and misfiring at idle will be swept away, replaced by a steady, regular, and rhythmic engine roar. When facing strong resistance during digging or climbing at steep angles with heavy loads, the horsepower output is extremely agile and smooth, and the previously glaring black smoke from the exhaust pipe is instantly cleared, allowing your machinery to regain its peak performance.

• Direct Sales from Our Own Modern Factory and Ample Stock: Many cross-border buyers often encounter the unfortunate situation of long international parts supply chain procurement cycles and high-value machinery being forced to remain stationary on-site for weeks due to the shortage of core components. We rely on our technologically strong self-built manufacturing base to maintain a large, regular inventory of this popular 328-2580 model. This pure factory-direct model supports rapid, lightning-fast order fulfillment, eliminating layers of intermediaries and ensuring your equipment can return to operational status in the shortest possible time.
• Full-spectrum digital rigorous quality control and ultra-hard surface wear resistance: Some low-end replacement parts on the market, due to insufficient wear resistance on their sealing surfaces, are prone to internal pressure loss after short-term operation due to minute impurities in diesel fuel, leading to failure to build up fuel pressure when hot and stalling under high load. Therefore, every injector we manufacture undergoes multi-dimensional, full-condition flow and pressure limit verification on a digital common rail test bench. The control valve needle and core moving parts have been comprehensively upgraded with a DLC (diamond-like carbon) ultra-hard nano-coating process, structurally sealing off potential wear hazards and ensuring excellent long-term durability even under harsh fuel environments with high temperature and pressure.
• Precision Multi-Orifice Geometry Calibration and Superior Fuel Efficiency: Addressing the issues of sluggish engine power, excessively high cylinder temperatures, and abnormally high fuel consumption caused by nozzle flow rates deviating from factory calibration, this product is meticulously manufactured based on OEM data standards and electronic parameters. The precise multi-orifice nozzle geometry ensures fine and uniform diesel fuel particles under ultra-high rail pressure, achieving a more perfect mixture and combustion with the air in the cylinder. This not only completely eliminates the persistent problem of black smoke in the exhaust during machine operation but also significantly improves fuel conversion efficiency, helping owners save substantial hourly fuel costs during long-term operation.

High-Intensity Continuous Excavation Construction for Infrastructure and Road Earthwork: At highway infrastructure and tunnel excavation sites with extremely demanding schedules, a 336D tracked excavator equipped with a CAT C9 engine is continuously breaking and loading heavy loads against hard rock layers. Because the frontal resistance is constantly undergoing large-scale, high-frequency dynamic changes, a slow-responding fuel system can easily cause the engine to stall. The 328-2580 injector, with its exceptional hydraulic servo airtightness and rapid response, maintains precise and stable fuel supply even under prolonged high-load, high-vibration conditions at full power output. This ensures swift and powerful equipment operation, guaranteeing uninterrupted and steady project progress.

Open-pit quarry and heavy-duty unloading transportation conditions in mines: In the dusty, rugged terrain of open-pit mines, - heavy loaders loaded with tens of tons of crushed stone traverse long, steep inclines. Facing heavy loads climbing slopes, operators must maintain high throttle output to prevent engine speed drops. This injector, under extremely high operating rail pressure, maintains a stable and perfect fuel mist pattern, ensuring complete fuel combustion. This guarantees that the loading machinery can continuously extract significant torque even at low speeds, easily traversing steep slopes and preventing engine stalling due to fuel supply pulsations.

Q: How can I confirm that this injector is perfectly compatible with my diesel engine?

A: The matching requirements for high-pressure common rail system components are extremely stringent. The most direct method is to check if the side of the old injector housing removed from your original vehicle has a laser-marked or stamped code containing "328-2580" or the corresponding Cater-pillar remanufactured part number "20R-2284". If you are still unsure, you can send a photo of your engine serial number to our customer service staff, and we will conduct a free technical verification using big data analysis.

Q: If I purchase this high-pressure injector from your independent website, do I need to send back the old, defective core charge?

A: Absolutely not. We operate on a pure factory-direct, net-price model. What you order is a brand-new, upgraded, high-quality injector product. You don't need to go through the cumbersome process of sending back the old core charge, saving you expensive international cross-border shipping costs and transit time, making your parts procurement simpler and more transparent.

Q: How long is the warranty period after purchase? What should I do if a malfunction occurs within the warranty period?

A: We offer an official quality guarantee of up to 12 months (one year) from the date of receipt. During the warranty period, if the product operates in a clean and qualified diesel fuel environment but experiences any non-human-caused malfunction due to its own manufacturing quality, simply contact our after-sales team and provide a simple inspection report. We will provide free replacement parts or accessories as soon as possible.

Q: What technical installation advice do you have for our mechanics when installing this brand new high-pressure common rail injector?

A: Modern high-pressure common rail systems are extremely precise high-pressure hydraulic networks, and are highly susceptible to contamination by micron-sized dust impurities or trace amounts of moisture in the fuel. Before installing the new injector, please ensure that a technician thoroughly empties and cleans the original vehicle's diesel fuel tank and low-pressure fuel lines, and replaces the fuel filter with a brand new high-specification diesel filter. Installation in an environment ensuring 100% absolute purification of the fuel system will significantly extend the lifespan of the new fuel pump. Additionally, please remember to have the corrected code flashed into the ECU under the guidance of a professional technician.

Q: What is your current stock situation? Approximately how many days does it take for goods to be delivered to our country after an order is placed overseas?

A: As a factory direct sales outlet, we maintain a large and ample stock of this model of injector in our central finished goods warehouse year-round. Within 24 to 48 hours of your payment, your goods will undergo multi-layered vacuum rust-proof and shock-proof packaging and be delivered to leading international express delivery companies such as DHL, FedEx, and UPS.
