104641-7300 Fuel Injection Pump 1046417300 Np-Ve411f1100rnp2501 for Komatsu

This model of diesel engine high-pressure common rail fuel pump assembly (standard part numbers: 104641-7300 / 1046417300, common cross-reference and OE interchangeable numbers include 104741-7300, 16700-69T00, 16700-69T01, etc., mainly matched with classic diesel power platforms such as TD27, TD42, and QD32, widely installed in commercial pickups, light passenger trucks, and engineering vehicles) is meticulously manufactured. As the pressure establishment and core fuel supply assembly of the fuel supply system, it bears the important responsibility of efficiently boosting low-pressure diesel fuel and delivering it to the common rail chamber or distribution lines on time and in precise quantities, providing a stable and consistent fuel supply pressure guarantee for each cylinder.

The product adheres to industrial manufacturing standards of "high-pressure steady-state establishment and micron-level precision matching." The pump body is made of high-strength forged alloy steel, while the internal plunger assembly and oil pressure control valve are made of specially quenched bearing steel. The surface is coated with a low-friction, ultra-wear-resistant hardened plating, effectively preventing internal scoring and pressure leakage caused by diesel impurities. After the parts are installed, drivers and mechanics will experience a very noticeable improvement in operation: crisp and rapid cold starts in the morning; stable oil pressure establishment and significantly reduced operating noise at low idle speeds; and a responsive and sensitive accelerator pedal during heavy-load starts, full-load uphill climbs, or long-distance cruising acceleration, resulting in smooth acceleration and continuous power delivery, providing a rich and smooth driving experience and excellent fuel control.

• Advantages: Intelligent manufacturing in a physical factory with standardized production throughout the entire process.

  Problems Solved: Effectively reduces intermediate procurement costs, addressing issues such as accumulated tolerances in parts, slow oil pressure establishment, and potential high-pressure seal leakage inherent in traditional OEM and multi-level distribution chains.

  Value Brought: Leveraging a self-operated standardized production base for precise control, eliminating intermediate markups, and ensuring highly consistent pressure and flow parameters for each high-pressure pump, this reduces maintenance budgets while providing robust and reliable power for vehicle and equipment operation.

• Advantages: Rigorous quality inspection using a full-condition ultra-high-pressure digital dynamic test bench.

  Problems Solved: Addresses the issue of pressure relief, jamming, and response delays that can occur with low-end high-pressure oil pumps under complex operating conditions, leading to reduced engine power or frequent downtime.

  Value Brought: Each high-pressure oil pump undergoes fully automated digital testing before leaving the factory. Pressure stability and sealing response are precisely calibrated under simulated high-temperature and ultra-high-pressure conditions, ensuring immediate usability upon installation and significantly saving time and costs associated with equipment disassembly, assembly, and debugging.

• Advantages: Large-scale warehousing with readily available stock for rapid delivery response.

  Problems Solved: Addresses the costly delays and lost work losses incurred due to fuel system failures causing breakdowns in high-attendance production tools like construction machinery and commercial vehicles.

  Value Brought: The warehousing center maintains ample stock of best-selling specifications year-round, enabling rapid response after order confirmation and priority packing and dispatch within 24-48 hours. This significantly shortens logistics and delivery cycles, helping fleets and owners quickly restore equipment availability and effectively avoid downtime losses.

• Advantages: Aerospace-grade hardened plungers and high-density corrosion-resistant seals.

  Problems Solved: Addresses the issue of premature wear, scoring, and pressure relief jamming of internal plunger components caused by differences in diesel lubricity and sulfur content across different regions.

  Value Brought: The core plunger components utilize high-strength special bearing steel and surface anti-corrosion hardening treatment, greatly improving fatigue resistance and wear resistance. Even under harsh environments and prolonged high-load operation, it maintains stable performance, avoiding the additional costs of frequent disassembly and repair.

Intercity Express Delivery and Short-Distance Freight Scenarios: Small vans and light passenger vehicles are frequently in fully loaded delivery mode, requiring the engine to continuously provide stable high torque output in the low-speed range. When vehicles experience starting difficulties, excessive acceleration, or stalling under high load, the maintenance team promptly updates the high-pressure fuel pump assembly. A stable and powerful fuel pressure supply restores the engine's full power, easily handling frequent start-stop cycles and heavy loads, ensuring continuous and efficient transportation operations.

Field Engineering Transport and Off-Road Passenger and Freight Transport Scenarios: Diesel pickup trucks and multi-functional work vehicles operate frequently in complex road conditions and construction sites, placing extremely high demands on the stability and anti-pollution capabilities of the fuel supply system. When operators find that the equipment struggles to climb slopes or that idle oil pressure builds up slowly, replacing the pump with this high-pressure fuel pump can quickly restore high-pressure fuel supply, ensuring continuous and stable engine output under harsh operating conditions and improving work efficiency.

Q: Can I install the product directly after receiving it? Is additional calibration required?

A: Each high-pressure fuel pump has undergone full-condition pressure and flow calibration before leaving the factory. Provided the fuel lines are clean, it can be directly used after a professional technician installs it according to the standard connector torque and removes air from the fuel lines.

Q: What is the delivery time and inventory status for bulk purchases?

A: We have our own production base and large warehouse, and we maintain a large inventory of this model. Standard orders can be shipped within 24-48 hours, and large-volume orders can also be arranged for rapid factory production.

Q: What quality inspections does the product undergo before leaving the factory?

A: All oil pumps are assembled in a Class 100 cleanroom and undergo 100% high-temperature, ultra-high-pressure dynamic bench testing. Strict monitoring of build-up pressure, oil return volume, and sealing performance ensures stable performance after installation.

Q: What is the warranty period for the product? How are quality issues handled?

A: We offer a 12-month warranty for this product. During the warranty period, in the event of performance failure due to non-human factors, we will provide rapid replacement or after-sales technical support to protect your rights as a user.
