Don't worry, it's still kinda fun at this stage. No hydraulic puller; I was trying to nut out a way to use the limited hydraulic resources at my disposal to accomplish this task but I came up kinda blank. I don't think my 20-ton shop press would be quite equal to the task.

Blue should have been about 600 f. That will give about .0015 expansion from room temp on a 2 inch bore.
I guess that quantifies my problem Greg; I've machined .0025" interference into these parts on a nominal 1.75" bore. I say 'nominal' in that the bores were as close as I could manage with my not-very-precise line-boring arrangement, then the bushes were individually matched to each bore plus .0025".
I'm reasonably confident that I can get them home using the tractor-driven puller arrangement and some heat; the first one went within a poofteenth while cold, so a bit of barbecue gas will surely help matters. Just a little time-consuming is all, but I have to work with what I have.
