How to remove Ritchey cranks?
How do I remove my Ritchie WCS cranks? The crank has an outer hole with a metal hollow screw and inside that is a slightly smaller bolt for a 10 mm allan key ( ithink). I cant really think of another way to describe it. I have a key for the inner bolt but when I unscrewed it it came loose and then tightened again as I continued to turn the key. Do I just keep turning and it extract itself? (ita an octalink bb). Do I need to remove the outer "collar" and then use a crank extractor tool? I just cant see how to remove it because its a non standard size. |

I just cant see how to remove it because its a non standard size. I think self extractor with a 8mm allen wrench-lefty loosey. If all it does is take the crank bolt out, go to a decent LBS and get the plug that goes into the end of the BB spindle so the standard crank puller has something to push against. |

Agree, if "Penny" is confused about removing a crank, it would probably be best if she/he went to a LBS and have it professionally removed. The LBS could also answer all of her questions re different cranks and bb compatibility. Alternatively, if Penny insist on doing it herself, it could follow Park Tool's excellent repair article on octalink/isis cranks: http://www.parktool.com/repair/readhowto.asp?id=120 Good Luck! |

I once pushed a round bolt through the square drive hole with a crank extractor in ca1993, the bike shop had a good laugh when I took that in, the crank was off. Also, to add insult to injury, the chainrings were riveted to the crank arm. dan |

But ever since I've always remembered its in there and to take it out before trying to pull the crank arms. |

Thanks. It seems the BB is hosed :-(- Hide quoted text - What bb, ultegra? dura ace (with loose bbs, that needs to be rebuild after every rainstorm)? 105? Replacements are available, but I recommend buying a few as octalink is history! |
