Welcome to the forum, your first post gets its images removed (antispam feature). I quote it to get the image to show.
On topic: the focusing ring is threaded (very fine threads), and needs to be unscrewed to be removed. BEWARE! Unscrewing the focusing ring without taking note on exactly where it comes loose from the focusing helicoid can make the lens useless. Make sure you know what you are doing.
What is it that you are attempting to do with the lens?

Welcome ufysa!
The whole front section of the lens, including front elements, screws off the back section -- close focus first to get a better grip.
