Bosch 0445124024 | Direct Replacement MAN Injector Assembly

 

The Bosch 0445124024 is a CRIN piezo common rail injector engineered for heavy-duty commercial vehicle applications, offering precise fuel metering and high injection pressure stability up to 1,800 bar . As a direct replacement for MAN TGX and TGS series trucks equipped with the D3876 engine platform, this injector ensures optimal combustion efficiency, reduced particulate emissions, and sustained power output in Euro 5 and Euro 6 compliant powertrains .

 

 

This injector operates as a piezo injector with a F00VX60105 nozzle assembly, enabling faster response times and multiple injection events per cycle compared to conventional solenoid designs . Critical for workshop matching, this part number carries the following cross-references: 0445124052, 51101006195 (MAN OEM), and 51101006189 . Repair shops should note that the service kit typically includes the nozzle, control valve, and high-pressure seals. The injector is classified under the Bosch CRIN series, characterized by its integrated rail pressure sensor and complex hydraulic servo system that must be calibrated during installation . For rebuilders, the nozzle service part F00VX60105 is essential when overhauling this unit, as it dictates the spray pattern and atomization quality directly impacting fuel consumption .

 

 

The primary application for the 0445124024 lies within the MAN TGX and TGS heavy-duty truck ranges (model years 2014 onwards) . Specifically, it is compatible with the 15.2L D3876 engine series, covering engine codes D3876LF01 through D3876LF12 . This includes high-output variants ranging from 513 HP (383 kW) up to 631 HP (471 kW), making it suitable for long-haul logistics and heavy-load transport across European and North American markets . Additionally, the part has applications in Neoplan Starliner coaches where the same engine architecture is utilized . When sourcing, ensure the cylinder head design matches the CRIN3 injector class, as these are typically secured via a clamping yoke and specific hold-down bolts .

In high-mileage fleets, the wear of the nozzle needle and valve assembly leads to a measurable increase in return flow (leakage) and a drop in injection quantity . This direct injector part number is central to maintaining the hydraulic servo system balance. If a unit fails, it often results in increased black smoke (soot), rough idling, and ultimately, DPF clogging . By sourcing the Bosch 0445124024, operators mitigate the risk of secondary damage to the high-pressure pump and rail. For repair shops, understanding that the piezoelectric actuator requires specific coding to the Engine Control Unit (ECU) is vital; however, this specific model often runs within a compatible "generation" where software matching is required only if the injector classification (IQA) code changes . Regular replacement of the F00VX60105 nozzle during overhauls restores the injection rate shaping necessary for compliance with Euro 5/6 emission standards, significantly improving the longevity of the after-treatment system .

 

 

Q1: Is this part a direct plug-and-play replacement for my MAN TGX?
A: Yes, provided your truck utilizes the D3876 engine family. Verify your engine code against the compatibility list (e.g., LF01, LF02, LF09). While physically direct, ensure you transfer or reprogram the classification code (IQA) to the ECU to avoid injection quantity deviations .

Q2: How do I confirm this injector fits my specific Euro standard (Euro 5 vs. Euro 6)?
A: The 0445124024 and its cross-reference 0445124052 are used across both standards; however, the injector is physically the same. The difference in emission performance usually lies in the software logic of the engine. Always check the OEM number 51101006195 to confirm compatibility for your specific chassis number .

Q3: What is the lifespan expectation for the piezo stack in this injector?
A: In heavy-duty applications, the piezo actuator is typically reliable for over 500,000 km if the vehicle uses clean fuel and regular filter changes. However, when misfire or high return flow occurs, it often indicates the nozzle or control valve is worn, not the piezo element itself, and can be rectified using the F00VX60105 repair service .

Q4: My mechanic is installing it, but we have a "rough idle." What went wrong?
A: "Rough idle" post-installation is often caused by air trapped in the rail-ensure manual priming of the fuel system was done . Additionally, verify the hold-down bolts were torqued to specification; if over-torqued, it can seize the internal servo valve, and if under-torqued, it causes compression leakage .

Q5: Can I source this as a reman unit rather than New?
A: Yes, many suppliers offer remanufactured units for this part number . However, ensure the rebuilder is certified and replaces the control valve and nozzle rather than just cleaning the core, as the specific clearances in the CRIN2/3 class require precise calibration to maintain OEM flow rates .

Q6: What is the difference between 0445124024 and 0445124052?
A: In most aftermarket contexts, 0445124052 serves as a successor or cross-reference part number often listed for the same MAN D3876 applications . They are frequently interchangeable, but 0445124024 is considered the primary base number for the specific F00VX60105 nozzle configuration .
