How To Remove Hydraulic Cylinder Pins

looking for some ideas on how to remove stuck pin on my case 580 stabilizer hydraulic cylinder. i need to replace the seals . I got the gland nut to unscrew with no trouble, but cannot become the lower pin to motion at all. should i merely oestrus it upwardly til i become some motion? any help would be appreciated.
Does the pin have a grease nipple?
If information technology does grease information technology or remove the nipple and put a mechanical oil (wd40)
Striking it 3-4 times i fashion
Grease/oil
Make clean with wire wheel/ brush or emery fabric

Hit the opposite way 3-four times
Echo

Then piece of work information technology i style and the other till it moves 1 way easier
But remember don't mushroom the end you'll never get it out

If it is already mushroomed hitting it as far as information technology will go then tidy up with a grinder on both ends until it'due south minor enough to escape
To add to what Learner said... do Non hit the pin straight with a hammer, always use a punch/rod in between the hammer and pin.

bigger hammer peradventure some estrus ?
Get out the stuck pin in place & rebuild the cylinder on the car .
Pull the cylinder barrel off the rod to supervene upon seals & o - rings .

Think backwards ...

If you don't want to employ td25c'south method (which is a good one), put a long hacksaw bract in a reciprocating saw and cutting through the pivot on both sides of the rod center. And so y'all can put the rod in a press. The pin may not exist seized in the rod. If it seized in both sides of the stabilizer y'all will have an easy job of burning or driving the pieces out. If you cull to burn the pieces out, drill a small hole through them so you won't destroy your cut torch tip. I accept done that many times with pins and seized bolts.

I just had the same problem on my 580 SL. There is a generous corporeality of room betwixt the rod eye and the yolk. I put a metal cut off bract on my Stihl 14" cutting off saw and cut the pin. Mine was stuck on side facing the front of the machine. I cut it there and pulled the rest of the pin out and pulled cylinder. And so I institute a piece of solid ane" bar in the barn and put it thru the yolk on the fresh cut end of the pivot. This helps go on rod in place. I held it and my brother hit it with a larger sledge and we had information technology out in 10 min. New pivot has a grease zirk in the end to lube this articulation. Pin volition cutting with sawzall as well. Information technology does not seem to hard. But Shihl saw cut it with no attempt in 20 seconds!
Thanks for mentioning the cutoff saw rick. I didn't even think about a using a gas powered cutoff saw.
I haven't had to cut any pins in the above discussed situation since I purchased my Stihl TS 420 about four years ago.
They are crawly saws.
