The locking ring internal threads are definately used by the nozzle holder's external M 24X2 threading, the prechamber's internal threading is M22X1. The precamber's internal threading is used by either a slide hammer type tool with an appropriate adapter or a screw press type tool specifically made to pull 61X prechambers. As I mentioned, I don't have a prechamber in front of me and the illustrations are not the most detailed but I'm pretty certain that is the configuration. I would also add that I can't see how it could be designed that the internal threading of the locking ring could be syncronised with any threading internal to the prechamber as the rotational alignment of the locking ring is independent and will vary under various torque conditions, this would prevent any possibility that the nozzle holder's external threads could engage any deeper than the lock rings threads.

Early 601/3 nozzle holders using the pin type prechamber locking ring have a similar arrangement although I'm not certain of the prechamber internal thread specs for these, could be the same M22X1 or they may be M22X1.5 the other end of the slide hammer adapter.

Later 603.97 and 602 engines using the splined type prechamber locking rings particularly those with inclined injection have nozzle holders with external thread M22X1 and the thread is located closer to the holder's tip and when installed the threading is actually further down into the prechamber's body. Good Luck!

this is the lock ring on a 602.911 motor, notice NO internal threads for the injector.

My concern would be threading your new tool into the buggered threads. Those PC s take ALOT of force to get out. Will the threads hold?

I plan to go see my welder tomorrow, we are going to make a prechamber puller out of a old injector. It will go in the prechamber and I don't care if it ever comes out again, due to the buggard threads. However before I can even get that far I need to rent, borrow or buy a spline tool to get at the prechamber.
I found a place online that sells the prechamber for $27 for my car but im going to call the Benz dealer in the morning and check their price.
