Why are you showing us pictures of the small end of the pulley.?? The bull gear pin #10-256, that disingages the pulley from the back gear is located on the large end of the pulley.? The only thing that holds the bull gear pin in place is a small spring and a small ball bearing that rests in a small detent that is on the flat surface of the bull gear pin.? I will see if I can get you some pics for your better understanding of the issue that your trying to do.

You need a tool to remove the circlip or snapring. If you're in the US, these will work:
Also available at any auto parts place. A pair of needlenose pliers may work. There are two kinds, inside & outside, or combination tools that will do either depending on the position of the pivot screw. The one in the link is a combination tool.
HTH!

Subject: [atlas-craftsman IO] Atlas Craftsman 3950 back gear question #10d-260 To: [email protected] Date: Sunday, February 17, 2019, 6:40 PM
I am new to the forum. New to metal working. New to lathes. I am...a total newbie! Just got my first lathe, Atlas 3950, knowing it was a hobby lathe, but just to get started and see if I even liked working on a lathe. I have cleaned up everything and was starting to do a walk through from the manual I got with it. I ran into a problem with engaging the back gear drive. I have seen the video where you pull out the coupling to disengage the pulley and gear so you can engage the back gear but, the problem is I can't pull out the coupling. It is aligned with the keyway and I can wiggle it around a bit, but it will not pull out. I have tried shooting some WD40 in to see if it act to release it, but no go. Hopefully the attached pictures will give an idea of what it looks like. Is there anything I am missing here? Anything I can do about it?
