XT Hub Question
I'm trying to clean and repack a couple Shimano XT hubs. The dust seals have a couple holes in them with an arrow indicating "open". I assume this means by turning the seal using the 2 holes. Is this correct or is there another trick here. Please see attached pic.
The open position, indicated by the arrow, can be achieved using just your bare hands(at least on mine) allowing you to inject grease into the holes with a grease gun.
Don't know for certain, but to look at it makes me think one might drop the tips of a spanner wrench into those holes and unscrew the ring in the direction indicated?

No. The open/closed is just for squirting in light grease if you're in the habit of underlubricating your bearings. You're much better off taking everything apart, cleaning and inspecting it, and reassembling with fresh grease and bearings:
