I replaced my bottom bracket yesterday, and decided to take the old one apart just for interest.
Basically it screws into the bottom bracket shell of your bike, put together it looks like this (obviously you wouldn’t be able to see most of it because it resides in the bike frame)
And disconnected it looks like this (Bottom bracket cups, spacers, plastic sleeve to keep majority of crap out)
Naturally, ignoring the ‘Do Not Disassemble’ warning and taking the only handy screwdriver to it, doesn’t really work too well:
Conclusion: Don’t try to service Shimano XT bottom brackets!



That’s quite odd as this is what i’m doing tonight with my little bike’s bb to get rid of the creeaaklick tink.. creaaklink… tink.. tink.. creeaaaklink

Dude, all your photos are broken in the RSS feed. I think it’s becuase you used relative URLs….maybe.

My BB had proabably more than 2mm of play in it when I replaced it - it was proper screwed.
Well noticed about the images, I obviously don’t RSS my own blog. Was being slack with the urls, hate having to put the domain name in.

eek, mine just needed tightened theres still a ticking clock sound which is driving me mad, its either something to do with dirt in the cartrige bearings or my chain is doing it.
