Shimano freehub body compatability
A ring inside the freehub, Shimano 105 (FH-5501) snapped and the base
separated from the body. Interesting ride home wondering what that wobble was, along with the chain flopping about while freewheeling. I'm trying to avoid having to lace in a new hub by replacing just the freehub body. I only had one Shimano hub in the parts bin and it came off of a mountain bike. It looks wider. Is it correct to assume that the mountain hub that I tried is probably 135mm, too wide for an old 12 speed alloy frame, but that a 130mm freehub body from that era would be a suitable replacement? -thanx |

They're sorta all of a type with a lot of small variances. First off, overall length of HG bodies is evident between six speed and the later 7+ speed versions. If it's not tall enough to hold all your sprockets, stop right there. The washer/shim/spacer underneath, between cassette body and hub shell, varies a lot. You may need the one which came with the donor cassette or the one on your hub now. Then there are the outer seals around the cone which not only vary but some are decidedly suicidal during removal. So maybe probably and if not donor cassette bodies are found on wrecked wheels behind your local LBS. Bodies of not-Shimano brands are generally not going to fit. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

Thanks for taking the time to respond. 8-) I wasn't clear in presenting the problem but you were clear answering: the substitute freebody is NOT wider, it's taller. Overall, I think I get it. There is a little more variation than you'd want to deal with, but it's doable with patience and attention to the details. Good. all the best! |

If you have an assortment of Shimano brand cassette bodies handy either new (as we do) or used (take a chance) it's very doable. Save your spare seals and spacers for future use, there are a good number of both. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

If it's not tall enough to hold all your sprockets, stop right there. After not being able to find new UG hubs anymore I installed a Shimano STX-RC on my road bike rear hub and slightly re-dished the wheel. Works. Well, maybe for another 3000-5000mi, then I'll need the next one. It barely fit the 126mm bike frame but it did fit. If it interferes with the chainstay one can always grind off the outer sprocket so it becomes a glorified spacer. The washer/shim/spacer underneath, between cassette body and hub shell, varies a lot. You may need the one which came with the donor cassette or the one on your hub now. Then there are the outer seals around the cone which not only vary but some are decidedly suicidal during removal. So maybe probably and if not donor cassette bodies are found on wrecked wheels behind your local LBS. Bodies of not-Shimano brands are generally not going to fit. Regarding the seals the salvaged ones didn't fit, of course. I kept some of the leather from my old army boots that unfortunately had hardened up. Cut out a matching size "leather washer", greased it up to the hilt and jammed it in there. It seems to hold up well. I ride rain or shine and the last axle lube didn't reveal any water ingress. -- Regards, Joerg http://www.analogconsultants.com/ |
