ah, dang. ok, will there goes that theory.

ok, how about the w114 240d--will those injectors work on an w123 240d?

guys, try to keep the useless posts to a minimum, please--there's already waaaaaay too much junk on the internet these days
(craig: you are reading this, aren't you?)

good to know, good to know

This I imagine, would be fine....same generation of engine design. The factory might actually have a different part number but I would not hesitate to interchange them because the difference would be slight.

300d na are the same as 240d but 300d turbo injectors have a different part number and are different enough I would not use them.

How's that?

so, just to be clear, the injectors off a 240d from the w114 chassis would be compatible with the w123 240d engine?

well i'd have to read through this entire thread to figure out how, and who wants to do that, lol

I am not advising you to do this. I believe it is probably true though. The best thing is to use the numbers on the injector as your guide and use what the factory specifies.

The original poster refers to a 190D 2.2 which would be a OM601 engine, this engine uses the same vertical injection design prechambers and prechamber rings as the OM615/616/617XXX and OM602.91X(without EGR) as well as OM 603.96X engines. All these engines use the pin-type prechamber rings into which the nozzle holder threads. So the nozzle holders for these engines are in fact dimensionally compatible!

The engines which use inclined injection OM602.91(as of 09/88 with EGR), OM602.961/2, and OM603.962/970. All these later engines use differently designed splined type prechambers rings and prechambers into which these nozzle holders threads into.

The injectors still screw into the prechamber, correct? The 601, 602 and 603 originally received the threaded collars that were thicker than the 61x engine's. But they can be updated with splined collars to work just as well.

The thread dimensions for the prechambers and the collars have been noted as the same... but their placement on the injector body is in question.

I know for sure that the 602 and 603 thread into the prechamber with the finer threads... I assumed it was the same on the 601.


edit: I may be mistaken here, but I thought the injectors on the 601 were the same as the 602.

ok, guys. so, can i use 190d 115psi injectors on a w123 240d?

will they screw in? and if so, will they work? i'm not a diesel guru, but if you guys wanna argue about it, feel free.
