My nemesis pin was driven out. Pounded halfway to one side, the ground some of the part of the pin that was out, and the interior of the bushing that was emptied. Then drove it back all the way out and it wasn't even that hard.
No pictures, but the three cylinders and rods are completely disassembled, and all seal and o-ring sizes determined and added to the cart on hercules. Would have liked to get the swing cylinders out too but it's not possible now. I'll expand on this later.
Pulled out the hydraulic hoses too. They've seen better days for sure.
Splitting the hoe assembly from the trencher though, big trouble there.
That’s great work@Eugen !
I’m glad you were able to get your revenge on that pin!
I’m not sure if you are someone else has been able to list o-ring and seal sizes for these backhoe cylinders and the front bucket dump and lift cylinders. If not could you show them when you can? I appreciate it!

Doesn't hurt much anymore Jeff.
After the kids were asleep I managed to get the pistons off of two rods. The nut holding the piston takes a 1-11/16 socket, which I don't have. Luckily, after heating it up, it came undone real easy with the 30" pipe wrench.
Piston, gland, seals, and o-rings ready to go inside and get measured. But not tonight. Time for

A trick I have used a few times with those odd ball nut and bolt sizes or big metric sizes, is to carefully measure and bend some steel banding to fit the nut so a bigger socket I have will fit. One time it took 2 layers of banding to get a good fit I call it a socket bushing
Maybe you could cover the nut with saran wrap, and then stick the big socket on there and then fill the cavity with something really hard/solid. Like some kind of concrete or grout.
Probably still not as good as steel though.

I can't tell for sure but it looks like most of your hydraulic hoses might have field repairable ends. If so you can take them off and put them on new hose yourself.

Good eye . Yes they sure do look like that . Just need to source the right type and size hose . @Eugen I have done these before . i can walk you through the dos and don't if you like .

I have a drill that had them on the hydraulics. Over the years we mostly replaced them but saved all the ends. With the crazy prices for having hoses made up, I think I'm going to get some of the proper hose and go back to them. They are actually pretty handy.

let's go, it's finally time to blow.
