Hi Carl, photos did not arrive. I'll pm my email address again just in case I typo'd it - many thanks! If you can send those specs too, that'd be great. To save time, you can just open your send folder and forward the email that you sent to OM incl. the specs - that way you won't have to reattach them
Cheers,
Neil

I can see going through the threaded version hassle to get the chambers removed but I sure wouldn't bother re-installing that type. Come to think of it if I was removing them I'd resort to other methods of getting it done and would most likely involve a welder.

After getting the pre combustion chambers out, inspected them, researched parts, we decided it was not worth putting the old cups back in...after all the work it took to get them out...
SO,...we bought 4 new ones, and put them in...We feel,...it is the "smart choice"...to use the new pre combustion chambers...
It's simply a matter of..."Not Stepping over dollars...to save dimes"...

Ok, fellow "Cat Skinners" !...
I've e-mailed Neil and Old Magnet more photos...
Might be that Old Magnet can post the photos for Archive purposes...to benefit others needing to replace pre combustion chambers...
