Fuel Injector 7485020204 Bebe1r17001 Bebe1r17101 Bebe1r17201 Common Rail Injector for Vo-lvo Diesel Engine Hde11 Hde13 D13K

This heavy-duty high-pressure common-rail diesel fuel pump assembly (Part ID: 7485020204 / 74 85 020 204; common OE cross-references include 85020204, 21901300, 21644598, 0445020150, 0445020087, etc.) is precision-engineered for high-displacement, heavy-duty inline-six diesel engines—specifically the D11/D13/D16 and DXi11/DXi13 series. It is widely installed in long-haul tractors (Magnum, Premium, Kerax, C/K/T series), specialized heavy-duty construction dump trucks, large-scale mining haulers, and high-power industrial emergency generator sets. As the core power unit responsible for pressure generation and stable fuel delivery within the electronically controlled high-pressure common-rail system, it efficiently compresses low-pressure diesel to ultra-high rail pressures and delivers a steady flow to the main rail, ensuring consistent, robust fuel pressure for high-horsepower engines operating under continuous heavy loads.

The pump body is precision-machined from high-density, aerospace-grade forged alloy. Internal components—including plunger assemblies, drive camshafts, and electronic pressure-regulating metering valves—undergo micron-level geometric tolerance machining and ultra-hard vacuum heat treatment. Finished with a high-adhesion, wear-resistant, and anti-corrosive coating, the unit effectively withstands mechanical scoring caused by impurities in low-quality diesel and prevents high-pressure internal leakage. Upon installation, operators and technicians will notice significant improvements in performance: crisp cold-start response and smooth, quiet idling. Whether pulling away under full load, climbing steep gradients, or cruising at high speeds with a full load, the engine delivers abundant, responsive power with linear throttle control, significantly reducing fuel consumption while restoring factory-level performance standards.

Direct supply from a standardized, smart-manufacturing factory. We provide high-quality, standardized assemblies to eliminate issues caused by complex distribution chains—such as excessive machining tolerances, unstable high-pressure output, and inflated procurement costs. Leveraging precision assembly on modern production lines and strict tolerance controls, we cut out multiple layers of markups. This ensures that every oil pump’s flow rate and pressure-building parameters are highly accurate, delivering reliable, long-lasting power support for heavy-duty equipment while reducing maintenance budgets.

Rigorous testing on ultra-high-pressure digital dynamic test benches. Inferior replacement pumps often cause excessive fuel supply pulsation and delayed high-pressure buildup, leading to sluggish acceleration or even engine stalls. To prevent this, every pump assembly undergoes comprehensive testing on a digital automated test bench before leaving the factory. We simulate harsh environments—including ultra-high pressure and extreme heat loads—to verify startup pressure, full-load flow, and return-line sealing. Units are ready for immediate installation, significantly saving time and labor costs associated with disassembly, installation, and tuning.

Large-scale inventory and rapid shipping services. Long-haul logistics trucks and mining equipment are high-utilization assets; sudden fuel pump failures can cause costly downtime. Our warehouse maintains a massive stock of standard models. Once orders are confirmed, items are securely packaged and shipped within 24–48 hours. This drastically reduces logistics wait times, helping fleet managers and equipment operators quickly restore operations and minimize losses from downtime.

Specialized high-hardness, wear-resistant plunger assemblies with anti-corrosion treatment. Poor diesel lubricity or particulate impurities in certain operating conditions can cause plunger assemblies to seize or seals to wear and leak pressure. Our core pressurizing plungers and high-frequency valve spools are crafted from specialized wear-resistant alloy bearing steel. Enhanced by cutting-edge surface hardening and anti-corrosion coating processes, these components offer superior fatigue resistance and durability, ensuring stable, reliable performance during prolonged heavy-duty operation in harsh conditions, while reducing the extra costs associated with frequent repairs.

Long-haul heavy-duty truck logistics: Heavy-duty container tractors powered by 11L or 13L diesel engines operating on trunk highways, involving prolonged periods of high-load cruising and continuous hill climbing. When vehicles exhibit sluggish acceleration despite deep throttle input, unstable common-rail pressure buildup, or dashboard alerts indicating fuel supply anomalies, the maintenance team installs this high-pressure fuel pump. Post-installation, rail pressure builds rapidly and steadily, and acceleration under heavy loads is robust, ensuring on-time arrival for long-distance logistics operations.

Large-scale mining material transport and heavy-duty engineering dump truck operations: Heavy-duty mining dump trucks shuttle between extraction sites and crushing facilities, contending with bumpy, dusty terrain, frequent high-torque starts, and slow-speed heavy-load crawling. When the powertrain suffers from hard cold starts, fluctuating idle speeds, or stalling under load, maintenance personnel promptly replace the unit with this high-specification common-rail high-pressure fuel pump assembly; the steady, continuous fuel supply allows the engine to instantly unleash powerful performance, ensuring efficient operational progress.

Q: Can the fuel pump be installed and used immediately upon receipt? Are there any special installation requirements?
A: All fuel pumps undergo calibration on automated digital test benches before leaving the factory and are ready for immediate installation. Before installation, ensure the fuel lines and diesel filter housing are thoroughly cleaned, replace all high- and low-pressure line seals with new ones, and manually bleed air from the system after tightening the lines to prevent damage to precision mating parts caused by dry friction due to a lack of diesel lubrication.

Q: What are the shipping lead times and stock availability for bulk orders?
A: We operate a modern factory and a large, professional warehouse center, maintaining ample stock of this model year-round. Standard orders are packed and shipped within 24–48 hours of confirmation; for large-scale fleet spare part orders, we can rapidly schedule production to meet delivery deadlines.

Q: What professional inspections does the product undergo before leaving the factory to ensure performance?
A: The product is assembled in a clean-room environment and undergoes 100% dynamic testing on digital test benches. We strictly monitor pressure buildup during low-speed starting, injection flow rates at rated operating conditions, the response of the electromagnetic metering valve, and high-pressure sealing integrity (zero leakage) to ensure excellent and stable performance upon installation. Q: What is the warranty period for this product, and how are after-sales issues handled?
A: We offer a 12-month warranty on this high-pressure fuel supply pump model. Should any performance failure occur within the warranty period—provided it is not caused by human error or damage from fuel impurities—we provide rapid replacement and professional technical support, ensuring you have complete peace of mind.
