OM617 Non-turbo heat shield stuck
I pulled my injectors to rebuild them and the heat shield washer in the #3 hole will not budge. I have used every available tool with no luck including PBB. Short of pulling and replacing the pre-chamber, should I take a shot at leaving the old one in? Looks unmolested.

Use a 1/4 " dia punch and a hammer to tap on the circumference of the heat shield. That will loosen the bind then use a 90 degree beefy pick (no flimsy cheap dental pick that may break the tip off) to pull it out.
If the above doesn't work, find a sheet metal screw or bolt and tap it into the heat shield and then rock it back and forth then out.

also, are you certain the shield is still in there? how carbony is it? I've had good luck with a dental style pic, CLEANING all around the edges of them and tapping on them as funola suggests.
it's really important to get all the carbon from around the outside of the shields and the threads that the injectors use.

Yep, the shield was still there. I wasn't sure at first but I stuck a toothpick in and marked the depth of #2 hole against #3 and 3 was more shallow by the depth of the shield. So I did as advised and tapped the circumference with a punch and now there is joy in hole#3!!
Not too much carbon...a lot of it came out on a shop rag on my finger. I'll take my cylinder brush and clean them out real good then suck it all out with my shop vac. Thanks again!
