Not a typical cup-and-cone bottom bracket, how to remove?
 

Hello, how the Dude do I get this B B out?

I thought about taking the rings off then beating it with a hammer but I didn't want to mess anything up... Also, it's really rusty but could you believe I rode on this BB as it is all the way across S. C. in June. now that the cranks are off I can't even spin it by hand as it is so rusty. major change needed!

How to remove "flushed" BB? no teeth on cups??? perhaps is the correct question...

This is a Viscount & I'll need replace the bearings. Any idea how much this is or where to find such a part?

thanks!

I've never seen one of these before but the obvious next step is to remove the C-clip. You have to pry the two ends apart to get out of the groove it's in.

What workstand are you using?

And in order to get the spindle out, there are some c-clips for you to remove. Then, take a dead blow hammer and start knocking the spindle on one side. It should start to come out the other side. From there, in terms of removing the bearing without damage to the frame I recommend you find a reputable LBS and have them continue.

remove the C-clip from the spindle, then use a bearing press to push the spindle through which will take opposite cup with it. Then use a piece of shaft and the press to remove the other cup. You might be able to do the same with a hammer, but if you have a friend with an auto shop it'll be much easier with a press.

Now, as far as your options for a new BB, I'm not entirely sure. Velo Orange has a threadless one, but I don't know if it'd fit in your BB shell.

Looks like a BMX stle BB. http://www.danscomp.com/456007.php?cat=PARTS

So you are saying the Bearing will stay put as I tap the Bracket through?

as seen here http://bikecult.com/works/parts/bbViscount.html

I'd rather not take this to a LBS as I am enjoying learning to work on these myself. That is sort of the point of these forums right?

here is a pic of the stand.

I'm not sure exactly what the name brand of the stand is but it works well for $25 bucks. I bought it used.

thanks for the help !

So I plan on tapping the bracket out, it will take the opposite bearing with it when it goes, then tap the remaining bearing out. Then I'll replace the bearings and reuse the Bracket. I'll post pics & let you all know how it goes.

any idea where I should get said new bearings?

thanks!

There's not a bottom bracket per se. It's a very simple design with a closely toleranced BB shell, a spindle with bearing locating shoulders, and a pair of cartridge bearings. The bearings weren't unique, so it should be possible to find replacements if the spindle is OK.

Ah, The spindle is the correct term then. Yes, the spindle is in perfect condition, not the best condition cosmetically but fine working order.

I'll look for the right bearings.

The original spindle measures 123mm long.
The square-tapered ends, measure 12.7mm wide at tip,
13.6mm wide at shoulder, and 15.5mm long from tip to shoulder.
The bearings are 6003, measuring 35mm OD x 17mm ID x 10mm Thick.

also, how does this spindle stay put on the Bearings? is it just really tight?

OMG! You might want to post this to the Classic & Vintage forum... they'll probably faint. I'm not 100% certain, but that appears to be an original "Death Fork": http://www.sheldonbrown.com/lambert.html

Personally I think you should take some of the advise above and find a bike shop who can service that for you.

that style was somewhat common on some early Ti and Aluminum frames.

becarefule with that spindle. a good auto/truck supply house (not auto zone I mean like Guidios auto and trans supply) may be able help you get bearings.

Yes, it's a really tight fit. The bearings are also pressed into the BB. You can do this at home with an assortment of washers and spacers and couple of high grade bolts (instead of the crank fixing bolts). First press the bearing on the non-drive side of the spindle using washers to assure that you press against the inner race. When you get the bearing to the appropriate location, leave the bolt and spacers in place. Go the drive side and fit washers and spacers over the spindle so that tightening the bolt on that side pulls the non-drive side bearing into the BB shell. Then press the drive side bearing into the shell with the washers and spacers from the other side. PM me if you need a batter explanation.

The bearings are 6003. They are commonly available.

Take the fork problem seriously.

the bearings are easily found:

Realize that bike may be better off in a museum or something. The fork and BB are known to fail prematurely.

if not at the LBS, any place that sells cartridge bearings.

You can find bearings by looking up your local machine supply store. You should have one locally if your town is big enough. I typed 6003 bearing into google and had lots of hits. Best seal for bike should be 2RS.

6003-2RS - rubber seal
6003-ZZ - metal seals
6003-OPEN - no seals

Speaking of bad things, how are the Viscount hubs? I have an old 36 spoke front hub I just rebuilt the sealed bearing in and was curious as to if I should use it or not.

They made their own hubs and they're stamped "Lambert". I like mine a lot.

Mine is only marked Viscount. The skewer look different from yours. Mine had a loop on the non lock side, but I ended up having to cut the skewer shaft to remove it as that side would not come off anyway I tried.
