Rebuilt all cylinders but the swing on 1959 case backhoe with Model 31 backhoe and Model 32 loader. I can't figure out how to get the swing cylinders off. Have included attachment photos. I'm not sure how to get the head of the cylinder attached to the backhoe (not the tractor end) off. There are two large bolts I can remove and look to be the approach for removal but how would I get those pins (above and below the cylinder rod) out? Any help is appreciated.

Remove the bolt & a pickle fork I think it's a peg pull out of glad head. Not much info

It looks a little confusing. If nothing else could you unbolt the the trunnion end from the cylinder and get a better idea how it comes apart?

I never did exactly that but one concern is the pin maybe worn - mushroomed in the bottom and not want to come out?
I would start with a wedge in the gap in order to know it is not holding. Then screw a slid hammer into the grease fitting hole. Have the bucket up so there is no pressure there and have someone swing it side to side while hammering.
Make a puller to screw into it?
Cut the pin in half with a sawzaw and deal with the pin later?
Just Ideas.

What model tractor is the backhoe on ? I may have the service manual for it.
The service manual should have detailed instructions for the removal procedure (maybe).
The pins you are asking about are usually not removable.
They are part of a trunnion and welded to the cylinder barrel. similar to this one.

That's what I would have thought but I wonder how they originally mounted the cylinder? I wonder if the cylinder could be taken a part and the backhoe swung to the side so the barrel could be taken off. Then the piston bolt/nut removed. Then take the pin out of the rod end and slide the rod out of the trunnion.
