What tools for crank/BB removal: 2012 Camber 29er
I think I'm ready to start doing more of my own maintenance, and have run into a few neewb questions.
I have a '12 Camber 29er, and the spec sheets say it has the following components
Cranks: Shimano Hollowtech Octalink spline replaceable rings
BB: Shimano Octalink spline cartridge bearing
Ive been watching videos on Youtube for the past hour, and I don't think I'm any closer to knowing what tools I need to pull my cranks and BB and give them a cleaning/lube.
I know alot of you do ALL of your own maintenance, and that sometimes Specailized has unique components; any help would be appreciated.

You need an Octalink crank puller to remove the cranks. You use this tool after unscrewing the hex bolt on the crank arm. Park Tool, among others, makes this tool.
Your crank may use a self-extracting system, such that unscrewing the hex bolt also pulls the arm from the BB spline. You can determine this pretty easily by unscrewing the bolt. If the bolt comes out, and the crank arm is still stuck on the BB spline, you need the crank puller.
To remove the bottom bracket, you need a tool with teeth that mesh with the 8 notches on the BB. Like this.
Park's site isn't working for me at the moment, but this guide will be handy when their site is up again: http://www.parktool.com/blog/repair-...ve-or-octalink
All that said, there's not much to do after removing the crank and BB, other than clean and re-grease the BB splines and threads. Bottom brackets have become throw-away parts, which you replace when the bearings are shot. For this reason, I don't bother to remove my cranks and BB unless something is creaking, or if the BB needs to be replaced.

Thanks for the info. Park tool's website isn't working for me either. I'll try removing the cranks tonight and see if I need the crank puller or not.

On a side note, looks like one of the housings is rubbing on the bottom bracket shell. You might consider putting some frame protection there...

Where do you see that?

On the first picture you posted, I'm seeing 3 cable housings. It looks like the upper one is touching the frame.

I see what you mean. I'll take a look when I get home and report back. It's all factory install, so I'd like to think there is something there...
-
Took a look, and there is one of those clear sticker thing-a-ma-do's right there to protect the paint/frame.
Good eye!

Thanks for the info!
I'll have to see if I can slack it up a bit. 40 mm isn't too much.

I have the recommend 40mm now, and boy it seems like a lot.
the 3 cables are almost even with the bottom of my bash guard.
But if that is what Specialized wants, that's what I'll do.
Thanks for the input everyone.
