Bosch 0414703005 / 0986441030 – The N3 Injector That Bridges Two Numbering Worlds

In the diesel parts business, a single component can wear many identities. The Bosch 0414703005 and its exchange counterpart 0986441030 are the same injector - two numbers, one purpose. One is the new production number; the other is the exchange (remanufactured) number that tells you this injector has been through Bosch's own factory-grade remanufacturing process.

For operators running Detroit Diesel Series 60 engines - particularly the 14.0L variants - this duality isn't confusing. It's useful. It means you have options. And in an industry where downtime is measured in dollars per minute, options matter.

 

The 0414703005 / 0986441030 belongs to Bosch's N3 Electronic Unit Injector (EUI) family - a system used on Detroit Diesel Series 60 engines built between late 2003 and 2006. Unlike common rail systems that pressurize fuel in a shared accumulator and distribute it through high-pressure lines, the N3 integrates the pumping element and nozzle into a single housing mounted directly in the cylinder head.

What sets the N3 apart from earlier injector designs:

Inline concept - the fuel metering unit sits under the plunger, making the overall envelope smaller than previous generations

Inwardly opening solenoid valve - controls both the beginning and end of injection with precision

Six spray holes at 146 degrees - delivers optimal fuel atomization and cylinder filling

The N3 EUI performs four critical functions:

Creates the high fuel pressure required for efficient injection

Meters the exact amount of fuel to handle the load

Injects fuel at the precise moment

Atomizes fuel for complete combustion

The ECU sends a command pulse that activates the injector solenoid, while the injector itself is mechanically actuated by the engine's camshaft. This hybrid approach - mechanical actuation with electronic control - delivers the reliability of mechanical systems with the flexibility of modern electronics.

 

The 0414703005 / 0986441030 is engineered for the Detroit Diesel Series 60 14.0L engine, specifically in EPA04 / DDEC V configurations. It serves model years approximately 2005 through 2008 - the EGR-era Series 60 engines that are still very much in active service across North America.

Truck platforms equipped with this injector include Freightliner, Sterling, and Western Star models from the mid-2000s - the workhorses that are still moving freight across every major highway in North America.

 

The 0414703005's technical specifications reveal an injector engineered for serious work:

Injection pressure: Up to 1,800 bar (26,000 psi) for efficient high-pressure fuel injection

Six spray holes delivering a 146-degree spray angle ensure optimal fuel atomization and cylinder filling

Service life: Designed for 5,000+ hours in heavy-duty use, reducing frequent replacements

Physical specifications (based on related N3 injector data):

Net weight per unit: approximately 1.2 kg

Gross weight per unit: approximately 1.33 kg

Single unit dimensions: 29.5 × 11.7 × 7 cm

Six-unit gross weight: approximately 8.34 kg

 

The 0986441030 isn't just a different number - it represents a different process. When you purchase the exchange version, you're getting an injector that has been:

Fully disassembled - every component inspected and measured against OEM specifications

Worn parts replaced - critical high-wear items replaced with new OEM-spec components

Re-calibrated - each unit assigned a unique calibration code in accordance with OE specification

Tested - on Bosch's own test benches to verify flow rates, spray patterns, and electronic response

Serialized - a unique serial number for traceability

The ECU only knows how to perform with the correct calibration code and can make the relevant adjustments. Each remanufactured injector comes with this code already programmed.

When to choose the exchange version over new:

Budget-conscious fleet operators who need OEM-grade performance without the new-part premium

Operators with rebuildable cores who can benefit from the core return process

Anyone who values the environmental benefit of remanufacturing - choosing remanufactured products protects nature and supports a sustainable future

 

The N3 injector is designed as an inline concept, and proper installation requires attention to detail:

Disconnect battery power before servicing - this prevents potential ECU issues

Depressurize the fuel system before any work begins - high-pressure diesel can cause serious injury

Remove the engine valve rocker cover to access the injectors

Clean the injector bore thoroughly before inserting the new injector

Ensure the nozzle aligns with the combustion chamber during installation

Torque the bolt to 35 N·m (26 lb·ft) - over-torquing can distort the injector body; under-torquing leads to combustion gas leakage

Critical note: After installation, the injector must be properly calibrated using the appropriate diagnostic tool. The ECU needs the correct calibration code to make the relevant adjustments. Bosch recommends verification of fitment through the Bosch AutoParts Catalogue, now using SingleKey ID.

 

The Series 60 is no longer in production. But the trucks that carry it are still earning revenue. The 0414703005 / 0986441030 directly influences:

Fuel economy - precise metering means every drop counts

Power output - optimized atomization supports complete combustion

Emissions compliance - accurate delivery reduces particulates and NOx

Service longevity - Bosch's remanufacturing process restores like-new performance

 

Q1: What's the difference between 0414703005 and 0986441030?
They're the same injector. 0414703005 is the new production number; 0986441030 is the exchange (remanufactured) number. The 0986441030 has been fully remanufactured by Bosch to OEM specifications, assigned a unique calibration code, and serialized for traceability.

Q2: What engine does this injector fit?
The 0414703005 / 0986441030 is engineered for the Detroit Diesel Series 60 14.0L engine, specifically in EPA04 / DDEC V configurations from approximately 2005 through 2008. It is also compatible with 12.7L and 11.1L variants of the Series 60.

Q3: What are the warning signs that my N3 injector is failing?
Common symptoms include loss of power under load, excessive black or white smoke at idle or acceleration, rough idle or misfires, increased fuel consumption, hard starting or extended cranking times, and fuel leaks around the injector. Injectors experiencing these issues should be diagnosed promptly.

Q4: What's a core charge, and how does it work?
A refundable core deposit is applied to encourage the return of used injectors for rebuilding. The deposit is refunded when a rebuildable core is returned in assembled condition. Cores that are damaged or incomplete may not receive full credit. Each remanufactured injector is assigned a unique calibration code in accordance with OE specification.

Q5: Can I replace just one injector, or do I need to replace all six?
You can replace a single injector, but replacing all six as a matched set is recommended for engines showing performance issues. A single new/remanufactured injector paired with five worn ones can create imbalances in fuel delivery. Matched sets ensure balanced cylinder fueling and performance.

Q6: How do I verify that this is the correct injector for my engine?
Use Bosch's official verification tools. The Bosch AutoParts Catalogue now uses SingleKey ID for authentication. You can also cross-reference your engine's serial number and original part number against Bosch's database. The serial number will be required when placing part orders. When in doubt, consult an authorized Bosch Diesel Center for professional verification.
