I am trying to open the top of Symmar-S 210 (the lens has considerable separation) but the thing does not give up.
What is the standard solution to make the threads to go more easy?

Um, er, ah, the standard solution is to replace the lens with one whose groups don't have separation.
The non-standard solution is just to use the thing. Separation manifested as heavy Newton's rights can make a lens unusable, separation manifested as rings of fire sometimes has no ill effect.
First situation. I have a 25/1.4 Cine Ektar II -- super lens for 16 mm film -- with EKCo's own 25-15 converter, which screws into the front of the lens. The converter's first group is badly separated, shows lovely Newton's rings. Film shot with it captures them very well.
Second situation. I have a 58/5.6 Grandagon ex-Graflex XL. Both cells have peripheral rings of fire, the rear cell has silvery spots near center. It shoots beautifully.
Ask you lens whether it is usable as-is.
Your not going to fix a modern plastmat lens with glue seperation unless you are prepared to open it up, dissolve the glue and re-glue it using the correct UV glue anyways (without disturbing the centering). Not worth it for a common lens like this.
No, no, I am not about to fix it. I just want to take the broken thing away and keep the meniscus in place.
"Be still and allow the mud to settle."
What are you using to try and unscrew the retaining ring? I have yet to see one I can't take apart with the SK Grimes tool, unless the rim is dented.
Indeed, this is my plan. He mentioned rear cell but front one will work also when I turn it around. I am using a iris clamp and as such this is not a problem for me.
I have only the front cell. I could also bought a separate meniscus lens but for that I should have figured out how to mount it. Symmar has this already covered.
