Has anyone done any work on the prechambers, I would think if you increase the amount of fuel than the size or shape of the prechamber holes might need adjustment? Does anyone know what the thread size and pitch of a 80's 617 injector is, are they all the same?

Injector bodies and threads are the same between all OM61x and pre-89 OM601/2/3 engines.

Thread pitch for the pre-chamber threaded ring (where the injector screws in and injectors) is M24 x 2. The pre-chamber size M22 x 1.

(10-07-2009, 11:19 AM)Motorhead Thanks, I was just scratch'n my head as I am looking this 617 over. What is the best place to buy the tools, what other tools will I need for this engine?
You can get good tools from here...
http://www.samstagsales.com/mercedes.htm#diesel
To remove the pre-chamber you'll need the threaded lock ring tool.
615 589 00 07 00
And this tool to remove the pre-chamber itself.
602 589 00 33 02
Or you can make the tools yourself.

The smog shop said they are being trained for '85 and newer, maybe right now they will just do a visual for EGR, and a cat for the Califorina Mercedes. He said that they are getting new equipment for the diesels, I will check with my friends at SEMA and see what is going on.

Well that makes sense. Starting in 1985, California MB diesel motors had the trap oxidizers. I wouldn't doubt that they would want to do a visual to make sure all the equipment is still there. I wonder what would be the penalty if in fact is what they are going to do and see a vehicle with it's trap ox removed with a Federal setup or a by-pass pipe.

My understanding is that they will check for Emissions equipment and do a snap test to check for smoke/opacity.
