overhauling the front hub
 

hi, i just started working at the neighborhood bike works, an orginazation to help kids earn bikes. i'm getting trained in the basics of mechanics, an i ran into a problem. i was overhauling my front hub, an as i fasten the wheel back onit sort of stops spinning. i have quick release, and when it isn't tightened it spins perfectly. i had it with absolutly no play an still spinning then it locked up. my boss suggested letting it have a little play, so i re adjusted an the same problem. so what i have right now is a very loose quick release so i can still ride it. any suggestions?

Don't ride it with a loose QR! It should have a little play that decreases when the QR is tighetened properly, but shouldn't lock up or get noticably harder to turn.

Your "boss" was (hopefully) referring to the cones when he suggested to add "play" not the QR.
Also check that the bearing cage (if you have one) is not installed backwards.
Remember the fingers of the cage go into the cup.
Enjoy

Agreed. More of a resource.

he was talking about the cones. the qr is just loose enough to help, it isn't dangerously loose. an everything is back togethr right. i may just replace the qr with an axle and see if that helps?

I have a question im wondering if somebody can help me with regarding my hubs. I have DT 240's and i cant figure out anywhere how to get inside to service it. I dont need to, im just curious of how.

what was the name of this boss?
