Tightening A Sealed Hub

Hi everybody

I just received a pair of reynolds alta race. they are tuned fine, but the rear hub is a little tiny bit loose. I service all my standard wheels with non-sealed bearings, but it's my first pair of sealed hubs. There is a nut on the left side that could be tightened with a 15mm flat wrench, other than that, looks like there is no way to unmount the hub.

Any advice on what to do or NOT TO DO ??

Thanks

Check to see if it is still a "little tiny bit loose" after it is mounted on the bike with the skewer properly tightened.
A properly adjusted hub will, don't ask my why, be a little tiny bit loose before it is tightened in the dropouts. I can't for the life of me understand how the cones compress on the threaded axle.

Steel is to a certain extent flexible, even if the deformation often is too small to be seen with the naked eye. When you close the skewer you're basically compressing the axle a little lengthwise, bringing the cones closer, which can be picked up as a difference in bearing play.
