I had to deal with the swingarm bushings a couple of days ago... For some reason, heating them with a torch didn't seem to do much for mine. Soaking them in PB blaster for a day helped a lot... And then the big hammer.
Also, if you are going to be putting in the new brass swingarm bushings, I highly recommend freezing them for a couple of hours beforehand beforehand. I took them both out of the freezer at the same time, and the first one went in easy... the 2nd which had thawed a bit was kind of a pain.
