    I have a Meyer 7.5' ST plow and I'm trying to get the hing pins out. Anyone got any suggestions?

    an air chisel with a blunt head chisel works fantastic.

    I made a "dogleg" punch out of rebar for those. it works great, unless they're really rusted in there.

    I tried an air chisel but i couldn't find a way to get it to push the pin out. These pins are very, very rusty.

    I tried everything short of dynamite to get mine out. Got them red hot. Air hammer, 10lb sledge and a punch. Ended up cutting the tube out and replacing the whole thing. Drilled and tapped for grease fittings on the new ones

    Drill and tap the end and use a slide hammer, make one ot of all thread and a nut . Use a weight block as the hammer part.Install and heat verry verry fast on outside and hammer out . Trick is to heat the outside fast and not the pin or verry little on the pin. I do this all the time at work on 3 and 4 inch rollers.Works for them and there are heat swelled in .

    i use a combination of things if they are really seized.

    heat with a torch and spray with pb blaster a few times to get it broke free so you can pivot through the full range from straight up to full trip. once this is loose, i use a combination of heat, pb blaster and the air chisel. it takes some back and forth to get them out, but it is a lot easier than trying to break you knuckles with a hammed and drift-pin.

    I had one once that was stuck so terribly bad, that I just blew that section of tube out of the sector with a torch, and welded in a new piece.

    Best way if they are stuck in the sector is to use a sawsall or cutt off and cut thru the pin in between the two hinge tubes.Once they are cut you can seperate the sector from the moldboard and then drive the half pins out,might still need some heat but it is alot easier with them seperated.Good luck
