    Anyone replace the bushings in the pusharms? I have new bushings that Scag list as spacers and can not get them in. The old ones may be in the pusharms but I can't figure out how to remove them. If they are in there they are so worn they are very thin and I can not grab them, in any case the new ones will not fit in the hole. It is #73

    Use a chisel and cut the old bushings out.
    They should break into chunks..

    If Scag calls them spacers, they're likely a flanged bronze bushing. Do what Slapper suggests----or I keep a length of 1/4" round hardened stock, ground to a slightly sharp angle, that will allow to reach through the arm and drive from the opposite side. Just an additional thought.

    Chopping with a chisel, but it's so thin it is hard to tell how far in to go. The "spacers" are steel and are not flanged, so I would think there is a stop inside the pusharm, but I can not see it.

    Probably doesn't have a stop...the pic with a chisel mark down the length of the bushing is right on the mark...once you have the groove deep enough...take the chisel to the outer edges of the bushing and driving straight in...crush it in..it will break into pieces....what a PITA job...

    On the 3rd pic down, you can see the back/inside edge of the bushing.
    I would do like Dutch said, only I would use a length of 1/2" round stock/bar that you sharpen on an angle, kinda like bologna sliced. Doesn't have to be hardened, just re-sharpen. In fact I have just such a weapon in my toolbox, comes in real handy.

    If you aren't able to drive it out following the suggestions above, try heating the area with a butane torch. That should cause the metal to expand, and the outer tube should expand more so the bushing may come out more easily. Don't get it glowing hot, the idea is kind of like putting a jar with a too-tight lid under hot running water to get the lid to expand so you can twist it off.

    You could put a drop or 2 of liquid nitrogen on the bushing and watch it fall out.

    Man, you know what else works great on small bushings? Adjustable reamer blades! I have an assortment of different sizes that I have custom ground into different shapes. I use a V ground one to split bushings.
    If you can get your hands on some, they are the hot lick. They make great hard a$$ small chisels!
