After getting pin under pressure and heat . Roll the bucket a little this may help break it free.

Loader Pins

Appreciate your thoughts, but not sure how I could do this. There is no drag on the pins from the bracket on either side. To put the pin under pressure the one bolt which is used t hold the pin in is removed. With the bolt removed I can put no twisting torque on the pin from the hydraulics.
Its raining today, so going to wait for a while. Need to move the tractor over from barn to the shop to use the welder.

Your 1/4 Grade 43 High Test Chain has only a 2600 pound working load limit. So you've only got 5000 pounds before it starts yielding. Nothing like 20 tons from your jack.
In my previous post, I was speaking about 3/4 all thread (local hardware grade) in a 30 ton hollow hydraulic cylinder. When I got a piece of 3/4 B7 with Acme threads... the bushing gave up without a fight.

When you tighten up the allthread to the pipe to the bucket bracket it should lock the pin to the bucket .if not just heat and tighten

You have a 30T hollow cylinder available? Like hosspuller said, get some b7 rod, weld a nut on the pin
and the cylinder should pull it out. I use 1.25” b7 rod with my cylinders, but you could probably get away with 3/4. I’ve pulled larger pins out this way...works for me anyway. Good luck

Same general principle as what I said except instead of a pipe you have a hydraulic cylinder that you can put the allthread through the center.
You need to make a plate to put over cylinder with a hole for the allthread to fit through. Put nut on all thread tight then pump out cylinder
You have to make spacers to take up slack if you don’t have enough throw to do it in one try

Photo worth a thousand words
OK, but would have to buy more stuff, dosn't seem cost effective for a few times I would need it

Not a bad price, wonder if my 4T porta a power pump will fit and work it, otherwise I need a pump and hose?

There are a lot of different sizes of those cylinders on eBay. Do a search for hollow ram cylinders.
Keep in mind that that the capacity in tons of force is one of three factors to consider. Bore diameter and stroke are the other two.
Yes you need a pump and hose.

Tons of force are what determines what you will need. The first one shown in that link is 10 tons.

Understand, need to know the surface area of the piston and the amount of pressure the pump can deliver, and amount of volume the pumps tank holds to determine if the pump output will actually be able to get 20 to 30T force

That’s why went with the pipe idea.
I almost drilled, found a piece of 5/8 all thread and pipe. Started to move things around so I could get the tractor out of the barn and just thought, wonder if this would work. I'm sure with a hole clear thru I could have applied heat better

Good job !!! Cheap to !
