Anybody know how to take this apart?

This is the hydro pump from my HF lawnmower lift. It is leaking where the bolt goes into the housing. Hopefully it’s just an O ring. I took a nut off the threaded bolt that goes into the pump housing but I’m not sure how to get the bolt out of the housing. As you can see the bolt has what looks to be a round sleeve with a hole in it where it goes into the housing. I can turn the bolt freely about 1/4 a turn counter clockwise and then it stops. Likewise I can turn it freely clockwise about a 1/4 turn before it stops. Not really sure what to do to remove the bolt as I do not even see anything to grab on the bolt to remove it. Anyone have any ideas?

Thanks.

Maybe a bearing puller if it's friction fit? I can't see it fully, maybe there's a c-clip on there and you need snap ring pliers?

Looks like if you can get that spring-assembly thing off the bolt, the bolt might slide out.

That looks like a mount for a pivot of some sort. It doesn't look like something that would need to be part of the fluid system. Are you sure that it is leaking there? What else connects to that bolt?

What is on the other side of the circled area?
