Success. Old bearings and races are out, new bearings and races installed, triple clamps back on. I'll finish the rest of the reassembly tomorrow along with some cleaning, and buffing of the fork lowers.
I found this site to be very helpful:
http://forums.sohc4.net/index.php?topic=1516.msg291278#msg291278The silly thing was, a previous owner already had tapered bearings installed, but I went ahead and swapped them out anyway, since I had done all the work to prepare.
The freezing of parts (lower triple clamp and lower bearing race) and heating the lower bearing on a hot socket, worked out well.
I love this sohc site!
