I’ve purchased an e class cdi 3pc injector removal kit but I can not work out how to put the brass piece together with the thread and nut to pull an injector out ???
 
Any pics? Sounds like the type you take the top of the injector off and screw it onto that? Be careful though, if you are re-installing the same injectors then don't lose any bits. Are they stuck hard? A hot engine helps.
 
Search anywhere for 'black death injector removal' - not suggesting you have black death on your engine - but all of the injector removal methods (including the official MB built pneumatic hammer) can be seen in action.

Worked how to use the kit, just the 27/29mm special socket sits on top the the injector and you just push/ pull with a ratchet or prefably a king bar and slowly the injector moves and pulls itself up and out the hole but, I managed to snap the bolt that holds this injector so although I’ve freed this one I now have a job to drill bolt out and for some reason I could not get a drill bit to cut into this thread so having to get a mobile mech to come out to me ..... funny because the last bolt I snapped in another hole drilled out with ease and I managed to just replace with new bolt, no hassle !
 
There is a water jacket underneath so be careful how far/deep you drill it!
 
Were you using a cobalt drill? They will cut when an ordinary HSS bit won't touch it.
 
A metal drill bit set I bought a few years ago which up until this last bolt had no problem drilling into them ?? Very odd.....
