Fuel Unit Pump 414755008 0986445013 1435558 Common Rail Injection Pump

This electronically controlled unit pump/high-pressure fuel injection valve body assembly (part identification code: 414755008 / 0414755008 / 0 414 755 008, common OE cross-reference and interchangeable parts include 0414755003, 0414755014, 0414755015, 02112860, 04287049, etc.) is mainly matched with TCD 2012 L04 / L06 and BF4M / BF6M 2012 series 4.0L / 6.0L industrial diesel power platforms, and is widely used in large tracked excavators, wheel loaders, asphalt pavers, mining transport vehicles and generator sets and other engineering machinery equipment) is meticulously manufactured. As the actuator responsible for microsecond-level pressure establishment and precise atomization in the engine's fuel supply system, it bears the crucial responsibility of accurately metering and rapidly injecting diesel fuel into the cylinder under the command of the electronic control unit (ECU), ensuring thorough mixing and combustion of fuel with the intake airflow.

The product adheres to the precision standards of "microscopic ultra-fine atomization and millisecond-fast response." Internal plunger components and control valve cores are made from aerospace-grade hardened special alloy steel, combined with ultra-high precision geometric grinding and low-friction polishing. The surface is coated with a high-density, ultra-wear-resistant DLC hardened coating, effectively preventing early erosion and seizing caused by diesel impurities. After the parts are installed, operators and mechanics will experience a very clear and intuitive improvement: crisp and rapid cold starts, and the severe vibrations at low-speed idling have subsided and become smooth; under heavy-duty excavation, steep slope climbing, or high-load continuous operation conditions, the throttle response is tight and sensitive, acceleration is smooth and the explosive power is continuous, resulting in satisfactory fuel efficiency control and a stable driving experience.

Source Manufacturing: A physical factory with standardized production throughout the entire process. Effectively reduces procurement costs by addressing issues such as excessive tolerances in parts, uneven fuel supply to cylinders, and high-pressure leaks caused by third-party OEM distribution chains. Utilizing a standardized production base for precise end-to-end control, eliminating intermediate markups, and ensuring highly consistent fuel injection in each cylinder, this reduces maintenance budgets while providing robust and reliable power for equipment operation.

Rigorous Quality Inspection on a Full-Condition Ultra-High Pressure Digital Dynamic Test Bench: Addresses issues suchs as response delays, pressure relief jamming leading to engine misfires and vibrations, and wasted time and money due to repeated disassembly and adjustment, often caused by low-quality parts. Each component undergoes automated testing on a test bench before leaving the factory, precisely calibrating fuel injection and sealing performance under simulated high temperature and ultra-high pressure conditions, ensuring immediate usability upon installation and significantly saving time and costs associated with equipment disassembly and adjustment.

Large-Scale Warehousing with Regular Spot Stock for Rapid Shipping Response For construction and mining equipment, which are high-upload productivity tools, the costly delays, defaults, and lost work due to fuel system failures causing downtime and disruptions are significant concerns. Our warehousing center maintains ample stock of best-selling specifications year-round. After order confirmation, we respond quickly and prioritize packing and shipping within 24-48 hours, greatly shortening the logistics and delivery cycle. This helps fleets and owners quickly restore equipment availability and effectively avoids downtime losses.

Special hardened alloy needle valves with corrosion-resistant hardened coatings. Addressing the issue of premature wear and valve core seizure caused by differences in diesel lubricity and sulfur content in different regions, our core valve components utilize high-strength special bearing steel and a surface corrosion-resistant hardening treatment, significantly improving fatigue resistance and wear resistance. This ensures stable performance even under harsh environments and prolonged high-load operation, avoiding the additional costs of frequent disassembly and repairs.

Mining and heavy-duty tunneling scenarios for large excavators: Large tracked excavators and mining crushing equipment operate continuously for long periods in high-dust, high-load environments in mining areas, requiring extremely high requirements for oil supply response speed and low-speed, high-torque output. When on-site operators notice equipment sluggishness, speed drops under high loads, or abnormal engine smoke, maintenance personnel promptly replace the equipment with this electronically controlled unit pump assembly. After replacement, fuel injection establishes quickly and stably, providing ample and smooth acceleration under heavy loads, ensuring efficient progress in mining operations.

Road Engineering and Asphalt Paving Machinery Continuous Cruise Operation: Pavers and rollers require extremely high precision and stable speeds during road construction. Fluctuations in engine speed can lead to uneven paving surfaces. When equipment exhibits idling vibrations or fluctuating engine speeds, technicians install high-precision fuel injection components. Precise fuel metering ensures consistent engine output, significantly improving construction quality and operational efficiency.

Q: Can I use the product directly after installation upon receipt? Is a calibration code required?

A: Each fuel injection assembly is calibrated during factory testing. After installation according to standard procedures, it is recommended to use a diagnostic tool to check the system data stream to ensure that the response parameters of each cylinder are restored to optimal conditions.

Q: What are the inventory and delivery times for bulk purchases?

A: We have our own factory and large warehouse, maintaining a large inventory of this model year-round. Standard orders can be packaged and shipped within 24-48 hours, and large-volume orders can be quickly scheduled for production.

Q: How do you guarantee the quality and performance of your products before they leave the factory?

A: All paint spraying components undergo assembly in a Class 100 cleanroom and 100% full-condition bench testing, covering key indicators such as sealing, pre-spray volume, full-load spray volume, and return oil volume. These stringent testing standards ensure that the products are of superior quality from the outset.

Q: How long is the warranty period? What about after-sales service?

A: We offer a 12-month warranty period. If a performance failure occurs within the warranty period due to non-human factors, we provide rapid replacement or after-sales technical support to ensure your peace of mind when using the product.
