I'm sorry, but I really don't know much about the names of stuff on
old tractors. Is it a wide front end, or narrow? Is this the part the
wide front end pivots on, or is it the part teh narrow front end
rotates around to turn the tractor????

in any case, brass is a common bushing material. It is soft, and
functions well for places that are greased regularly, turn, but are
not pounded on. So brass is good for bushings for the steering wheel
shaft, but not so good for wheel bearings.

UHMW is used for bushings, but it is not as tough as brass.

Steel is used. Again, you need to grease it. Harder obviously. I'd use
mild steel. The goal is the bushing material should be the softest
material around so it wears out the fastest, instead of your shaft.

Uhh , I think we missed a connection here . The bushings I'm making are for
a motorcycle springer front end at the bottom of the forks . There are 3
holes in the rocker , 2 of them need to rotate a few degrees as the springs
compress and extend . The 3rd is the hole the axle goes thru . I'm inclined
after talking to a couple of folks to use 4130 steel , I can get it
pre-hardened to 28-32 c (I think that's what he said) . With a case hardened
pivot pin (or stud as Harley calls it) the bushing should wear and leave
the studs intact ... which sounds good to me , cuz the studs are expensive ,
relatively speaking .
