Pre chamber questions
Pre chamber questions
what i understand is that you remove the collar by making a tool, then make a slide hammer with the right threads( i found some random part that will work for this today) then what do you do with the pre chamber? just clean them out or drill bigger holes? is it worth the effort? i already have the engine out and injectors out.
also the crush rings need to be replaced right? anyone have a part number for those or a source?
any links i might have missed would be helpful
thanks.
Ive tried doing research recently for what to do for the pre chambers, but alot of the threads have been 404'd.

Im still yet to find an actual guide on reaming them out other than "Take a carbide cutter on a dremel and ream them open .010"

'82 300D -3" straight pipe, ALDA deleted, 3in1 glowshift gauge, HX30, egr-less manifold, A/W intercooler
'14 Ram 6.7l cummins -G56 handshaker, wishing it was deleted
I got one that is tapered slightly. The way I look at it, the small amount of taper couldn't hurt, if not maybe even help

For the back ones you will have to go in steps to get them big enough, make sure you follow the angle of each port as they are different. Use a good "cutting fluid" for steal and go slow, if all you have used before is a drill bit, think of going VERY SLOW compared to a drill bit.
I used a cordless drill but I am a machinist so no big deal to me. For a novice I recommend getting a "hand Reamer" (they are tapered) and do them by hand.
There is no "procedure" of do this as only a hand full of us have dared to go against the MB gods and butcher the perfection that only MB can achieve lol..
A reamer is intended to finish a hole, so it will only remove a little at a time, generally no more than .015 inch per side.

i made a slide hammer with a 10 lb weight, and one of the pre chambers would not come out. i was really wailing on it, it broke welds a few times and finally stripped out the threads of the puller.
well, i couldn't get them all out so unfortunately i dont think its gonna happen on this engine.
