Alex AKX R1.0 freehub removal
I'm trying to get the freehub body off by following http://www.parktool.com/repair_help/..._freehub.shtml
. After taking the axle, cones, and ball-bearings out, I can't really figure out how to proceed. There's a hex-looking thingie inside the hub, but it's absolutely the largest one I've ever seen -- do I need to find a wrench to fit it? I tried pulling the freehub body straight off without success (though I didn't try too hard for fear of damaging something).
To give a feeling for the size of the thing I just stuck an 11mm OD circular bar through and it had about 2-3mm of wiggle room. Looking through the hub from the freehub side, I can just barely see the flats of the hex part; I'd estimate the ID of the circle I can see at ~12mm, which would suggest that I need 14mm or 15mm wrench. The ID of the cup on the other side is ~15mm, so I won't need a wrench larger than 16mm at most. (For the record, I have a metric ruler, but don't have calipers handy, which is why I'm estimating)
So am I (hopefully) missing something? After I eat and check back here for replies, I'm planning on heading to the LBS to see what they say, and possibly to Lowes or Home Depot afterward if I do in fact need a rebar-turned-Allen-wrench.
