It's real simple Take out the screw on the right side that holds the cylinder crane in place. It is the largest screw on the right side. It has a little spring and detent so be careful not to loose either when you take it out. After that, just slide the crane/cylinder out. Now you can push the ejector rod in and out and put some breakfree on it and let it work down into it tipping the assembly u and down. Also right where the bushing goes into the cylinder, there is the smallest (very small) gap between the cylinder and the bushing. I spray break free down around the cirfumference of that tiny gap Lubing like that I have never had to take the whole rod assembly apart. That always loosens everything thing up real well.Of course make sure you use gunsmith screwdrivers so you don't gouge the screw slot edges.
