So I've decided to work on getting my crash-damaged Pinarello F4:13 (broken top and seat tubes) frame resurrected by Calfee over the winter, and I've run into an annoying problem--I'm supposed to take the fork out of the frame and the damn thing won't come off. There's a non-threaded tapered spacer that just won't budge, and I'm not sure how to get it off.
Any ideas? I've not encountered this problem before so I figured I'd ask before I trash the head tube too.
(edit) It's not my bike, but the headset looks the same as this:
