replacing machined bearings in hubs

[lph]

Hiya all, I have a wobbly rear wheel on my road bike that needs fixing.

Since I know very little about road bikes I took it to my LBS, who decided that the bearings were shot but "very hard to replace", i.e. non-standard. I checked on the wide and wonderful internet and found that I could easily order 10 of them for 15 dollars, or go down to my local enormous tool warehouse 2 miles away and get them there...

So now I have a wheel with the innards taken out, and brand-new cartridge bearings.

Are these hard to put correctly back in? I've overhauled Shimano cup-and-cone bearings many times, but never this type. I'll check Park Tool etc., but it would be handy to hear from anyone who's done this.

Are they press-in cartridges or what? How did you get the old bearing cartridges out? A picture might be helpful.

Oh, sorry. I have no idea how they were taken out, the LBS did it for me and I got the hub back in pieces.

Here's a picture of the bearing, and of the assorted innards of the hub. I guess the bearing is supposed to be pressed in, there aren't any threads and the side surfaces are smooth. The surface is stamped 6000RS.

I believe the bearing cartridges get pressed into the hub. If that looks like a good fit and you're sure of the orientation, you could press them in with a long threaded bolt, 2 big washers, and a nut. Lightly grease the outside of the cartridges first to help them slide in.

Thanks Deb, I'll give it a try
