Wrap tape around the sleeve to protect it and use a big pair of channel locks to wiggle it off the crank. I second polishing the crank nose - important step. I can't see the pic too well on this iPhone but your seal doesn't look quite square. You can set up the crank sprocket to draw the seal in straight with the crank bolt to get it started. I agree that the seal goes in before the sleeve; at least, that's how I've always done it. And oil everything up well on install - it can be a challenge getting the sleeve to mesh with the oil pump drive gear. You'll know when you've got it right 'cause the sleeve will sit almost flush with the seal.
