How to Overhaul a Bike's Hub

Video Transcript

"Hi, I'm Travis at Mad Dog Cycles here in Provo Utah, we're talking about how to overhaul a hub, look at that. Put it here in the vise, actually an axle vise holder. Two tools that you need, at least for this hub; is a fifteen millimeter park wrench, really thin cone wrench and this is a seventeen millimeter lock neck wrench which is just a basic wrench really. You unlock the locknut and go ahead and unscrew the nut and you just want to do one side only, you don't want to remove the other side, try not to and just remove the cone, okay, this is the actual axle cone that rides in the ball bearings, okay. Now you can remove the axle from the hub and there you go, there's all those rusty balls right there. What you do is go ahead, if you have a magnet, that's usually the best thing to do is get all those balls out just use a magnet like this and these are quarter inch ball bearings, you can get them at any your local bike shop and you want to inspect the hub, make sure that there's no cracking inside those races, so wipe out all that grease there and inspect it, make sure it looks good. This one looks pretty good. It's better to just go ahead and buy these ball bearings, they're very, very inexpensive, they get ovalized over the years and so just go to your bike shop and buy some new ball bearings, these are quarter inch and there are like nine balls per side. Make sure you inspect the cone and make sure it is clean and not pitted, this one is really good. Re-grease it with the grease from the bike shop, this is from the bike shop, or any hardware store for that matter and grease it up, put the balls in, put the axle back in, reset it and you're good to go."
