Removing the crane and cylinder from the gun is easy as it is one of the major assemblies designed to come out of the gun. There are videos and instructions on how to do that. But if you want to take the ejector and cylinder off the crane that is a different story as they are captured by several small pieces that are not easy to disassemble and even harder to re-assemble. It's not impossible if you have three hands. At least that's what I have been told. Here is an article that briefly describes the procedure.
quote> One task, seldom undertaken and rarely necessary, is removal of the cylinder from the crane assembly. Since this involves removing the frame latch and the ejector rod, it is a scary proposition until actually undertaken. Then, like most of the Ruger processes, it becomes transparently easy. After either removing the grips or the entire crane assembly, observe the relatively large hole in crane in front of the cylinder. Stick a small tool-( I used a large caliber, unbent paper clip) into this hole and depress. Then shove the through-pin out of the side of the frame and start picking parts out. This single pin, visible with the crane /cylinder assembly locked in battery retains the latch, the ejector rod and they cylinder itself. Everything goes back together in reverse and just won’t fit if you put them pointed the wrong way. <end
