Well, actually, I mean the the spacer itself moved outwards on the axle. So when tightened the nut sits flush with the axle. I was more wondering if there's any danger involved with that.
(in the picture you can see a gap right near the fixed side of the hub, it's supposed to sit right there if I'm not mistaken)
