I have a 1.5" hydraulic cylinder pivot pin that is seized and will not come out. It moves easily on the cylinder end but is frozen to the sleeves in the square channel on either side.
The pin was held in the sleeves with vertical drift pins but over the last 30 years moisture has gotten in them and rusted the pin to the sleeves.
All the others I have removed came out with a few taps from a hammer and a 1" steel punch.
I tried welding a 1/2" bolt to the end and turning it out, didn't budge.
I have used heat (Oxy / acetylene torch), various penetrating oils (WD, PB, etc), no go.
I made the jig in the pictures with 5" channel and used a 10 ton hydraulic ram, no go.
I have just about run out of ideas, I am thinking about cutting the cylinder out with a hack saw blade and then working on either side's sleeves individually, but I don't want to take a chance ruining the cylinder.
Any Ideas ???
