This video does a good job of visualizing the intricate mechanisms inside an internally-geared bicycle hub.

Aligning the Alfines involves putting them into 4th gear and turning the fine adjustment on the shift until the yellow lines on the hub line up. It can easily be done every time you plan to use the bike. It is just easy to forget to do.

Alfine alignment

As for dealing with wheel re-installation and shifter cable reattachment , I customized a spanner to perfectly fit between the hub and the dropouts to either hold the hub in place while tightening the axle nuts or loading tension when installing the when reconnecting the shifter cable. I can't remember which. It might have been both.

Alfine spanner

After having failure issues using an Alfine 11 with a 29+ MTB (high torque setup), I have used nothing but cassette based drivetrains on everything but my folding bike. Also, my only local hub re-builder has stopped providing that service and Universal Cycles stopped carrying replacement internals, so I will probably not use an Alfine IGH on any new bikes.
