Cone wrench size(s) for XT hubs
Howdy. I've just built up a Surly LHT touring bike and used XT hubs on the wheels. I'm also planning a coast to coast tour next year and want to take some tools with me. I don't want to possibly damage the dust covers to see what's inside, but still want to know what size cone wrenches to take if I have to do any repairs or make any bearing adjustments. I've been to the Shimano site, but they don't mention the size. Thanks, OHB...

Also, the flats on the locknut are shaped in such a way that you can't use an adjustable wrench on them, so you will need 2 of one of the sizes (I can't remember if it's the 17 or 15...must be the 17mm).

The old Shimano standards used to be 13 mm for the front cone, 15 mm for the rear and a 17 mm regular box or open end wrench for all the locknuts. That has changed over the past years and I have hubs that use a 13 in front and a 14 in the rear and/or have locknuts that also require a cone wrench and/or require two cone wrenches of the same size......
The conclusion? Measure yours. MechBgon is quite right. The conical rubber seals are very durable so look under them to determine what wrenches you require.

Agree with the above remarks, plus now seems like a good time to take them apart and repack the bearings before the big tour, if you trust your expertise enough. Give them a short test period, check the preload after it and you're good. (Recommended even if they're new. Shimano apply grease very sparingly for no known reason.)
