Good question. After breaking loose the axle nut then removing the brake caliper and speed sensor, I raised the Spyder about 2" off the ground and used a phenolic hammer on the nut end of the axle (with the nut still on it, flush with the shaft end). After the shaft was even with the swing arm, I used a long socket to further drive the shaft out... it was pretty easy. Then, I raised the bike enough for the wheel to drop down and eased the belt off the sprocket... I was surprised it worked, but it did. Did the same in reverse to put the belt back on. Ran the bike in gear while it was lifted about 3" off the ground for the belt to self-align & to make sure I had brakes.
