Basic hub service
 

I've looked for an online tutorial on this, but didn't find one in the usual (Park Tools and Harris Cyclery) sites. I think I've got enough background on how to do this for my Specialized Hardrock, but I'm hoping someone here can point me to one I haven't seen yet.

I've adjusted bearings many times for drum brakes on my older cars as well as the tempremental and complicated tapered roller bearings on the steering head of my first motorcycle when I rebuilt the front end. But I haven't had to dish a wheel yet, is that common when doing basic hub service on a bicycle? What else is unique to bicycle service? Thanks in advance!

If the wheel is correctly dished and aligned in the first place it won't change when doing hub service, so there's no need to touch the spokes.

The spokes are on the shell which is unaffected and will be in the same place after service as it was before. The only time hub service would affect dish is when you respace the axle which would move the shell to one side or the other with respect to the axle's locknut faces.

+1 Dishing involves the spokes and rim. Hub service can be accomplished even without the hub being laced up to anything.

Reading the two articles "Cone Adjustment" and "Hub Overhaul" should take care of it:

If you need to redish the wheel after hub service, you reassembled the parts wrong.
