Offered here is an unusual genuine Garrett electronically actuated variable-nozzle turbocharger marked:
Garrett development number: FG222613-0002 DEV
Additional identification and markings include:
- Garrett electronic actuator: 712120
- Hella actuator family: 6NW008412
- Turbine housing: 706142-1
- Compressor housing: Garrett A/R .46 M53
- Turbo family: appears consistent with GTA1852VK / GT18 VNT architecture
- Closest known production application: Garrett 727461-series Mercedes-Benz OM646 2.2 CDI turbocharger family
The important feature of this particular turbo is the FG222613-0002 DEV identification. This does not appear to be a standard Garrett production/service number. The "DEV" marking indicates that this was a development/engineering assembly rather than a normal production replacement turbocharger.
Based on the housing configuration, dimensions, Garrett/Hella electronic actuator and associated component numbers, this unit appears to be closely related to the Garrett GTA1852VK / 727461 family used with Mercedes-Benz OM646 2.2L CDI diesel engines.
Typical production applications of the related Garrett 727461 family include Mercedes-Benz:
- C-Class W203 C200 CDI / C220 CDI
- E-Class W211 E200 CDI / E220 CDI
- OM646 2.2L CDI engines
IMPORTANT: This turbocharger itself is marked FG222613-0002 DEV, NOT 727461. The 727461 number is provided as the closest identified production family/reference only. Because this is development hardware, the buyer should not assume direct bolt-on interchangeability with any production Garrett or Mercedes-Benz part number without independently confirming dimensions, actuator calibration, flange configuration and application.
Approximate physical details
The unit has:
- Approximately 1.5-inch compressor inlet
- Garrett A/R .46 compressor housing
- Three-bolt turbine inlet flange
- Large V-band turbine discharge
- Approximately 3.325-inch outside diameter at turbine outlet V-band flange
- Garrett/Hella rotary electronic VNT actuator
- External VNT actuator linkage
- Complete compressor housing, center section, turbine housing, actuator, linkage and mounting bracket
- Shaftrotates smoothly, no housing contact, no perceptible axial play.
Please review the photographs carefully. Several photos show actual dimensions measured with calipers.
Condition
This is a very clean genuine Garrett development assembly. Please judge cosmetic condition from the detailed photographs.
No claim is being made that this is a newly manufactured retail/service turbocharger or that it has never been used in engineering testing. Because it is a development-marked component, its exact operating/testing history is unknown.
It is being sold as a rare Garrett engineering/development turbocharger assembly and should be purchased by someone capable of confirming suitability for their particular application.
What you see in the photographs is the actual turbocharger you will receive.
