Mercedes-Benz W123 W126 300D 300TD 300SD AiResearch Garrett Turbocharger OM617.
This AiResearch Garrett turbocharger came off of my 1980 Mercedes-Benz 300SD Turbo Diesel (W116). I purchased one that was already rebuilt so didn’t need to provide a core. I didn’t have time to wait for parts to have it rebuilt. However, this one is good as it is if you’re looking to replace one that is shot. Just a reminder that this is a used turbo. Rebuild it if you desire to and have it singing like a song bird!
Please make sure that this turbocharger fits your vehicle. If you have an OM617 turbocharged engine, more than likely it will. However, just make sure and cross reference.
