Does the oil hole in Sturmey-Archer gear hubs also lubricate the bearings?

I am gradually repacking all the bearings in my bicycles with grease. However, I don't know how to do this with Sturmey-Archer gear hubs - is the oil that is poured in through the lubrication hole sufficient, or does it need repacking as well? Thank you.Does the oil hole in Sturmey-Archer gear hubs also lubricate the bearings?
Yes, use light machine oil in the hub. If you are adventurous and want to tear the hub apart, you may repack the outer bearings with lithium grease and lightly coat the gears inside with Vaseline/petroleum jelly before reassembly. You can then maintain the hub with a few DROPS of machine oil every now and again.





EDIT: Trevor... you didn't read my answer very well. FYI, Vaseline- PETROLEUM JELLY- is an excellent lightweight lube for close tolerance parts, not too good for bearings. Try it next time you rebuild an internally geared hub and be amazed.Does the oil hole in Sturmey-Archer gear hubs also lubricate the bearings?
The oil administered through the lubricator is for the gears only and does not reach the bearings except by seepage, the bearings can be regeased as on any other hub by removing the locknut and cone, see

Sorry to disagree with Mirageguitar again,(see seat post question) but do not use Vaseline, this is not a lubricant, not for gears in any case, and attracts dirt.
As always, Sheldon has the answer: http://www.sheldonbrown.com/sturmey-archer.html#lubrication





It seems that you don't need to repack your hub, and that you should use oil rather than grease to lubricate it.
