Yes, press in fits often take way more pressure than you realize. If you have ever had the luxury of pressing out and then pressing in a new bearing in an upright rigid press with a simple hand operated hydraulic jack, you soon realize just how much force is being exerted - enough that I try to be extremely careful as breaking an old bearing loose can be nerve racking and downright dangerous (especially when it pops loose and things go flying).
I would not recommend removing material from any new bushing (or any new bearing) so it presses in easier. The press fit is so the bushing (or bearing) does not end up spinning in your casting which is a bad thing.
Really the only thing that can be done in some cases is to put the new bearing in the freezer (shrinks it a whisker) and put the casting in an oven and heat it (expands it a whisker). This will make the pressing together of the two parts slightly easier. Of course this is not always practical or possible-LOL.

Dad got her out there, explained how the clutch was the same as in our o
