The correct powers customer tool is required here, set it tight and low, put blanks into all the cylinder, watch the direction of thread, mostly left hand after 1950s or so, and tighten snug, dont overdo it. Then when the extract rod isn't totally straight you can make it very nice in the Powers ejector rod and yoke straighten tool (expensive tool).

I use loctite on everything like buffalo red sauce but NOT here. NO
