Busted rear hub?

Hi everyone.

I've picked up a 'Republic Bike' brand bike at a garage sale, and it was cheap enough that I figured I could make a budget build project out of it.

I took it to a bike junkyard to get a tire for it, and the guy looked it over and told me something about the rear hub was knocking a bit. ( flip flop hub ) and when you spin the wheel, it has a ticking noise.

He said something about the barrings may have an issue or something like that, he said he could take a look at it and if its fixable, it would only be about $15, but it it was bad i'd need a whole new rear wheel.
He was closing up for the weekend, and said to bring it in monday and he will look at it.

But i'm looking to see if any of you guys had any further information of what he was talking about and maybe how I could repair it myself.

look up on youtube on how to take a part a fixed gear hub. Depending on the type of bearings you might just need to clean and re-pack (grease) and restore. You'll need cone wrenches (thinner). If you're new to bikes or not that handy its probably best to have someone look at it for you.

tools are not a problem, i'm a super mechanical guy, but i've not owned a bicycle in probably 10 years. I just learned from previous DIY projects that its always better to ask first.

Upon further research, I want to remove the cone from the hub, but finding that is a little difficult right now. Can you remove cones from a sealed hub?

Post some pictures of what you have. Since we are talking about a Republic bike, I will assume this is the original wheel with a very basic cup-and-cone hub that is in need of adjustment or overhaul.

As it sat when I got it $60, then I spent about $50 for a new rear tire, and the components to add a rear brake to it, so right now i'm at $120ish, and want to try to keep the whole thing under $150, as I may try to flip it for a little profit. ( live in a huge hipster town where people go nuts for these things )


Here is where i'm at on the hub, i've removed all the nuts, but can't seem to get the cone to come off?

GOT IT:

Apparently i use cartridge style bearings.

A little persuasion with a hammer and I got it all apart.

Sweet, now to find a replacement bearing

Any bike shop worth a tablespoon of salt will have replacement 6001 cartridge bearings.

yeah, I'll replace both bearings, apparently one side the bearing fell apart and was causing the issue.

I'll get it all going, then probably break the entire thing down for a full tune up and clean up the frame real nice, I love the baby blue color, but its super dinged up ( no rust though ) and I'll see if I can find a similar color paint and pretty the thing up.
