Calling all techies--BB question...(5 posts)

Calling all techies--BB question...filly
Apr 9, 2003 9:13 PM
I've got a 2002 LeMond Buenos Aires, and my BB started creaking a couple of days ago (yes, it is the BB). I want to try and remedy the problem myself, but I've never messed with removing/installing a BB before.

I can't find the specs, and all I know is that the BB is a 105 type. I need to know the specifics, though, if I'm going to tackle this. As a newbie to this, can anyone tell me exactly what I've got. Is it a cartridge type? Is it adjustable? Do I only need the Park BBT-2 tool to do the job?

Thanks for the help. Later.

it is cartridge; only DA is adjustible still.
yeah all you need is BB tool. Parks, SHimano or any other. Nashbar sells off-brand cheaply it'll do the trick.

Just remember simpe rule: to unscrew go same directions as pedal good luck

Not sure if you have self-extracting crank bolts, but if not you'll need a crank puller in addition to the BBT-2. Once you get the BB out, see if it still spins smoothly -- if not, replace it. When you put it back in, slather the threads with grease, anti-seize, or pipe compound to prevent future squeaking.

Also, although I know you're sure it's the BB making the noise, I have found that it's easy to get fooled. Be aware that it could also be pedal bearings, pedal to crank interface, crank to BB spindle interface, or chainring to crank spider interface. So if working on your BB doesn't make the creak go away, try the other things -- the remedy is the same -- remove / clean / grease / reinstall.

And a torque wrench?Kerry

In my experience, the noise often comes from not enough torque when the BB was installed or not greasing the threads well. You have to do BOTH. Most people cannot get the torque right without a good wrench.
