Wow, This is incredible. Those big beefy parts AND TOOLS! to do a man's job in a man's machine in a man's world and I bet 90% of my statement is now politically incorrect.
1800 ft-lbs on the crab nuts. I wonder how many times they can be torqued before they're stretched too much? What was the orange tool you put down into the injector bore?
I’ve been doing this kind of work for 25+ years and we’ve never changed any crab studs unless one was broken when we pulled it apart. Then you’re supposed to change all 4 on that power assembly according to the manual, but we usually just change the two on the one side that had the broken one. Never had any issues with those studs breaking other than just occasionally one here or there.
