Cone and QR issues...

I have re-packed this rear hub a few times without any issues, but things are a bit finnicky this time. I cleaned and regreased, and left the cones just a hair loose so that when i grabbed the end of the axle and wriggled, I could feel a slight tap. When I went to put it one the bike and tightened the QR, the wheel basically locked up. It's not rubbing the frame or brakes, and when I took the wheel out the cone adjustment hadn't changed.. I redid it twice and still the same result. Am I just being an idiot somehow? Anything I'm not thinking of? Cones need to be looser still?

Thanks

That's a new one on me. If there is no play in the adjusted bearings the wheel should still turn when installed.
Are you sure that you have the correct number of ball in the hub. Usually 9 1/4"balls per side.

Bikes: too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter

Yes, an extra ball can wreak havoc with the bearing.

It's also possible that your dropouts aren't parallel. If not, when the wheel is tightened the drop will bow the axle effectively shortening it and tightening the bearing. Usually this is not nearly enough to lock a wheel though, just throw the adjustment off.

So start by rechecking the ball count, then follow by making both sides of the axle are tight, then if still having problems look to the dropouts.

sweet thanks. I don't have the bike in front of me but I'll check the bearings when I get home. As I recall the dropouts were fine but that makes sense. I'll check. Maybe I tweaked it without noticing. They're Maillard Helicomatics. I took out 26 bearings total so I thought it put 13 on each side but I might have put 14 and 12..
