If it is steel, weld a bolt to it to pull it out. Tracy

IIRC, the bushings are some alloy of bronze or similar.

Used a "bushing splitter" on my D17
A bushing splitter is nothing more than a narrow chisel with an acute angled point., and almost square.
They work great for just this kind of bushing in a blind hole.

It's steel . May have to separate this piece from the steering box and see if I can find a friendly machine shop ? Don't have any welding skills . Thanks !!

Hope this isn't a silly question.  What is the purpose of this pin?  Mine has a grease zerk at the end of it.  If one  keeps it greased, in theory it should last forever.  Correct?  Thanks in advance.

Grease certainly would seem to help in my opinion . Maybe the pivot pin is there so the axle can move when you drive one wheel in a hole ? Maybe someone else knows ? Thanks

I wonder if building up this pin with JB Weld would hold up ? Might just be a waste of time and JB Weld ? Thanks

waste of time... I don't think JBWeld would survive the shock of a few 'gopher hole' events.....

Not JB....just weld it up and dress it down with a angle grinder. Don't have to be perfect. Fiddle with it till bushing slips over it.

I could be wrong , but don't think there is a grease fitting hole ? Plan to slap some grease on the pin when I put it back together . Thanks !

Cram a piece of loaf bread in the old bushing and take a piece of shaft 1 1/4" and drive the bread in it and it should push the bushing out. Is this bushing available from Agco? I need one for my 170.

If it's steel, I like to run a bead (or 2x 180 degrees apart) with the welder.  It needs to be hot enough it will heat all the way through, but don't want to burn through.  If you do that, the heat of the weld expands the bushing, and as you're welding it, it creates a soft spot for the expanded bushing to squeeze together.  When it cools off (let it cool off on it's own, not rapidly with water), the bushing should be nice and loose and come right out.  Putting them back in, throw them in a freezer and take a propane torch to heat up the opening just before you go to put it in and it should drop back in.

As you can tell from the pics I kept after my old bushing with a hammer and chisel until it finally shattered . Prolly should've done like Hurst suggested but I just tapped the new one in . Good luck !
