I'm taking out the jackshaft on my 99 VMAX 700sx in order to replace the bearings, and I'm kind of stuck on getting the brake disc off. The manual very helpfully says "remove the brake disc collar", referring to the spacer-type thing with no set screws that sits up against the brake disk on the jackshaft. How am I supposed to remove this thing? It's perfectly smooth, can't get behind it cuz it sits right up against the brake disc, and seems to be very stuck on there. Only thing I can think of is to get out the 3 jaw puller and yank the brake disc off with it, but I'm afraid of warping/damaging the disc if I do that. Anyone have any tricks to get this sucker off? Am I missing something obvious?
