Been a while since I've been on the forum and have run into an issue with my SuperMag cylinder being gummed up from some old oil and it won't rotate free enough (not binding just gummy) for the action to spin it when cocking the gun. I have researched the large frame take down threads and it looks like quite the undertaking. I do most of my gunsmithing that doesn't require machining, but I don't know if I want to get into trying to reassemble this tricky lower frame.
I have tried spraying cleaner multiple times into the crane assembly and ejector rod and it's still gummed up. What I was wondering if there is a way to remove the cylinder from the crane without tearing the pistol apart? It's very different from a Smith. Any thoughts and help would be appreciated.

I think you're going to have to pull the trigger group and then remove the crane retainer clip. You can then remove the crane and cylinder. From there you can remove the cylinder and clean everything up.
It's not really that hard, especially if you use the fishing line trick.
Anything worth doing is worth doing well.

Yep you have to remove the trigger guard to remove the crane lock. Make sure to use a couple cases to support the extractor when you unscrew the extractor rod.
It’s really not that difficult once you understand it. For reassembly I stand the hand straight up, get it engaged in the slot it needs to be in then move the assembly up tight to the frame but slightly forward of where it cams in. Then slowly move the rear end down while pushing the transfer bar forward (I use a small screwdriver) into it’s slot. Once the transfer bar gets in it’s slot I push the rear up. Then slowly rotate the guard back and slightly down without actually pulling it out, it’s more of a rearward move than down. Once the front latches in then push the rear up and latch the back.

I added a few more pictures and a video on the tutorial if it helps
