broken

I had to get that yoke off of a parts tractor I have here last week for another guy who broke his. I was able to get between the yoke legs and the tractor housing with a hacksaw and sawed the bushing off on both sides of the housing. Once the yoke was removed, I was able to determine that that bushing has a slit in it. Using a big punch from an angle, it was quite easy to collapse the portion of the bushing that remained in the housing. That bushing is 3/4" ID and 1" OD and is readily available from someone like Motion Industries or even a Category 2 to 1 toplink adaptor bushing would do!

In view of the stresses the bush sees when in use, I would hazard a guess that 'your' bushing was, shall we say, an 'unapproved' fix.

Remove the RH wheel and mud guard - that way you get better access with the BFH (4lbs is good).

Make up a drift that will fit through the hinge pin support on the axle, but will not pass thro the 'pipe' you need to remove, i.e. is in two parts, and stepped appropriately.

Apply BFH to drift repeatedly, adding PB blaster, WD40 or similar at regular intervals. The hardened 'pipe' is a press fit into cast iron and needs effort to shift it outwards, and eventually through the larger hole in the LH hinge-pin hole.

Be very careful if you adopt the threaded rod/nut approach as cast iron is not good with shear stress and is liable to crack with no warning, leaving you with a bigger problem than you first had.

TIP: on reassembly, cover everything in copper-based grease before drifting it back in again - someone will thank you for it in 50 years time, and it will make it easier for you if you have to remove it again.
