S&W Mod 65-2 -> Cylinder difficult to open sometimes

[rtcatz]

Got is some days ago, the gun is in excellent condition, internally the grease used was fully dry and was really difficult to remove.
The gun works perfectly, perfect timing, distance from cylinder to barrel perfect, cylinder play perfect etc..
The only issue is then sometimes when i open the cylinder it is "easy" to do it, sometimes it requires force. The Cylinder stop is in perfect condition.

The only part of this gun i haven't been able to open an clean was the cylinder ejection rod, it moves freely but i cant get to disassembly it, it is just too stuck.
When i press the cylinder release it all moves normally.

Any tips on disassembly this cylinder ejection without a bench vise? I had tried using some protection on the cylinder ejection port, handling the cylinder with the tip of the ejection rod on the right and turning it clockwise with pilers without success.
Any ideas on what could be my issue of it not opening easy all the time? i fell some kind of "resistance".

There are below 8 pics + 1 video of the issue.

Extractor rod may need some attention but must get the assembly apart first. Many threads on this, try searching the topic. While your doing that you can soak the assembly in some penetrating oil.

Thank you, sorry but i am not mother tongue in english, i don't get it, so the issue could be related to the cylinder extraction rod?
I can leave it with WD40 for a long time, no issue on that
What do you mean by assembly apart? you mean disassembly the cylinder extractor to get to the two springs?

update:

I had leaved it socking in WD40, still was not able to disassembly it.. but strangely it got a little better, the "hard to open cylinder" improved a bit. I was also thinking, couldn't it be related to the picture 4 thing?

This a long deep soak and try again. Some “lubricants” turn to glue after years (exp some of the newer “wonderlubes”). Years ago I bought a Russian sis that was in great shape BUT had obviously been in military storage for a LONG time. The russki version of cosmoline had set up like cement and it took a long time and a LOT of work to get it gone,

A difficult to open cylinder could be the result of gun shot residue and hardened lubricant in the locking bolt and spring. If soaking that area in WD40 helped, I would say that you have found your problem. I would recommend soaking it in a real solvent, something like paint thinner or any gun cleaning solvent would be better than WD40.

Intermittent difficulty opening of the cylinder would likely be caused by misalignment of the yoke, "runout" on the extractor rod, dirt/shooting debris inside the cylinder assembly, extractor rod/front locking bolt interface issues, and/or excess end shake. (and many others)

You should be able to disassemble the cylinder assembly by placing a drill chuck on the extractor rod (not on the end, but on the shank) tightening it completely, and turning the chuck to the right. Your extractor rod is reverse threaded. Be sure to put some empty casings into the cylinder chambers to protect the extractor.

There are tools to grip the extract rod without crushing it (it’s a tube). Remember the threads are left hand on a smith.

Assembly - I'm referring to the cylinder/extractor rod, extractor etc. all together. Sorry about that. The rod screws into the extractor and can be stuck from dried oil and/or rust or overtightening. Soaking is your friend in order to avoid breaking the rod at the threads (I've done it) or bending something. The area you pointed out is likely where the binding is coming from but may or may not be the problem. The end of rod may be putting uneven pressure on the locking bolt as it turns. The locking bolt likely is fine if it moves in and out freely.
