The problem is not the bush, when a new c/ratio gear is fitted to the 1st motion shaft they are pressed on and welded in place this can shrink
the bore of the 1st motion shaft so the bush will go part way in and then go tight. Some need a light polish to the bore to give clearance
or you may need to grind the bore out with a small grinding point while rotating the gear as its the far end of the bore that shrinks the most
then polish with a small emery drum. I have had to do this to most of the c/ratio sets I have fitted.
