500061326 / 0414703 Series B2B Procurement Cross-Reference Hub

Finding the correct part number in the heavy-duty diesel sector can be difficult due to constant updates and supersessions. Whether your equipment logs show 0414703xxx, the spaced variant 0 414 703 xxx, Iveco's factory stamped 504287070, or the alternative 504125329, they all trace back to the exact same heavy-duty fuel delivery asset. This B2B sourcing catalog eliminates ordering errors by consolidating old supersessions, updated production lines, and alternative Bosch/OEM reference strings into a single verified solution. Stop worrying about mismatched component codes; this Electronic Unit Injector (EUI) fits perfectly and restores your engine to original factory specifications.

This premium Bosch-engineered EUI bypasses the layout vulnerabilities of centralized common rail pumps by generating extreme localized pressure directly over each cylinder head. It provides absolute physical and mechanical compatibility with:

Heavy-Duty Commercial Fleets: Engineered for Iveco Stralis, EuroTrakker, and Trakker logistics platforms running Euro 3, Euro 4, and Euro 5 emission-compliant powertrains.

Displacement Match: Optimized for high-displacement Cursor 10 and Cursor 13 (F3AE / F3BE series) intercooled diesel engines.

Cross-Industry Machinery: Fits select heavy-duty Case IH and New Holland agricultural tractors and harvesting machinery utilizing the Iveco industrial block layout.

⛓️ Direct-Drive Structural Rigidity

Unlike standard common rail systems where pressure travels through long, flexible steel lines from a central pump, this unit keeps fuel compression entirely self-contained. The mechanical force of the overhead camshaft acts directly upon the internal plunger, eliminating fuel line expansion issues.

⌛ Instantaneous Hydraulic Response

By cutting down the physical distance between the point of pressurization and the spray nozzle, fluid lag drops to near zero. The integrated high-speed solenoid delivers micro-second fuel metering precisely when required.

🌋 Superior In-Cylinder Stabilization

The unit injector can generate extreme internal injection pressures exceeding 2,000 bar without straining external fuel lines. This massive force optimizes atomization, resulting in a cleaner burn, smoother engine idle cycles, and better protection against cylinder wash.

Q1: Why does Bosch list this injector under both 0414703xxx series numbers and an 0986xxx reference?

The 0414703 codes represent brand-new units sold through original equipment channels. The 0986441026 number indicates a factory-remanufactured component built by Bosch to identical tolerances, offering a more budget-friendly option for fleet maintenance.

Q2: My old injector is stamped 504125329, but my manual says 500061326. Can I safely install this unit?

Yes, absolutely. Iveco frequently updates its internal part numbers due to supplier changes, material modifications, or assembly line updates. Both codes point back to the identical Bosch EUI design, ensuring a perfect physical fit and proper ECU communication.

Q3: How does the lack of a shared high-pressure common rail protect my Cursor engine from total system downtime?

In traditional common rail systems, a single leaking injector or damaged rail relief valve can cause a pressure drop across the entire fuel system, shutting down the engine. Because this unit injector handles fuel compression independently, a localized issue will not cause a complete system pressure loss.

Q4: Will I need to flash the engine ECU when replacing an old 504287070 with this 500061326 injector?

While a full software reflash is usually unnecessary, you must program the unique calibration code (IMA classification code) stamped on the new injector head into the vehicle's ECU. This ensures balanced cylinder performance and precise injection timing.

Q5: What causes internal plunger wear in cam-driven unit injectors, and how does it manifest?

Plunger wear is typically caused by micro-abrasives in low-quality diesel fuel or poor fuel lubrication. Over time, this allows fuel to bypass the compression chamber, leading to hard cold starts, decreased torque output, and increased crankcase oil dilution.
