  • How do I remove these bearings ?

    I’ve stripped my frame down to do a bearing swap but I’ve got no idea how to remove this set of bearings from it …..

    It looks like there is a sleeve between each bearing which means I can’t get a drift of the back to get it out ?

    Any ideas ?

    Is the sleeve fixed or can it be levered to one side so you can get on the lip of the bearing?
    If not, a bearing removal tool and slide hammer would be the right way.

    Depending on size, it might be possible to use an expanding fasterner to lock behind the bearing to drift it out.

    Sleeve seems to be held in place by O-rings, probably a drift will work. A blind bearing extractor would be ideal.

    Had the same problem with the Enduro out in the Alps, had to pay a Specialized dealer to change it.

    Was thinking of putting this into the tool kit for future but not sure if its the right one for Specialized bikes and don’t want to buy it if it wont work

    Given your previous maintenance issues – take it to a bike shop.

    What are these previous maintenance issues you speak of ?

    I’m quite happy to do the job but would rather be able to do it without damaging the frame.

    Frame is a 2014 stumpy evo 29.

    You can tell by some people’s questions that they are gibbon fisted….

    Mmm ok. My only question about a maintenance task on a bike was over 4 months ago and that was how to get a set of cranks I’ve never had before off a bike.

    Isn’t the whole idea of the bike part of the forum to ask questions about bikes and bike maintenance or are you just being a knob ?

    Fwiw I strip and rebuild various ejection seats and parts of the Typhoon aircraft for a living so know my way around a toolkit.

    FWIW I had 16 years in aircraft engines, and you’d be amazed how many useless fitters there are!

    So this should be a dawdle for you, yet here we are…
    FWIW any other mechanical experience is pretty much irrelevant. I’m a fairly good bike mechanic, but wouldn’t know where to begin with a Typhoon aircraft.

    I’m with Nobeer on this one: If you can’t figure out a simple matter like this just by looking at it, you probably should take it to a bike shop.

    IMO, yep of course it is, nowt wrong with your question it’s more useful than 90% of the posts on here.

    I’ve done the other bearings but didn’t want to wreck the frame by trying to whack these out.

    Fwiw I would say I’m a fairly competent bike mechanic. I’ve stripped and rebuilt quite a few over the years however I’ve never had to replace a set of bearings fitted like this. Hence the op.

    Would the Ebay kit work or would it be just a waste of money

    renton

    As it’s only one set of bearings in one size that need removing I guess that eBay kit would be overkill.

    It would be a decent kit to have in a workshop with various bikes to do though.

    fwiw – I’d buy the kit just because I’d enjoy owning it.

    And it wasn’t an unreasonable question in the OP.

    Tracey,

    That Ebay kit seem to cover quite a range of bearing diameters so i would think that it would work for your assortment of Specialized bikes.

    The only way to really confirm would be if you know the bearing inner diameters of all the bearings on the frames.

    If Specialized publish the bearing numbers of the various bearings you could cross reference their size on a site like simplybearings to get 100% confirmation it is going to capture them all.

    For example the bearing in Renton’s top pic is a 6001RS
    these are the bearing dimentions. As you can see that one has an ID of 8mm so you would need the puller with the smallest adapter in the box.

    I had a similar issue with some Hemlock bearings and, if you’re happy to bodge an expansion bolt to work, then I did a bit of a guide on this thread…
    http://singletrackworld.com/forum/topic/sooooo-hemlock-owners-any-tips-to-shift-these-bearings
    …the principle is the same but its just finding a suitable sized expansion bolt

    Did you really strip every single component off the bike just to change the bearings?

    Just think of it as a Hope front hub and do the same as you’d do with that.
    Push the sleeve down a little and tap the bearing out from the opposite side.
    If the sleeve won’t move use one of these in the same size as the inner race of the bearing and knock it out from the opposite side.
    Really not very difficult.

    I do the bearings on my Yeti myself but that frame would have made me ask the same question here.

    I’ve stripped the whole bike down to do a full bearing strip and also a repaint as its looking a bit tatty.

    Thanks, at that price its worth a try, will get one ordered and find out what bearings are what. Ours was the drive side chain stay one behind the bottom bracket which was solid. €40 for the bearing and €24 to fit it.

    If you want to cover yourself get the specs for this kit

    It’s a very nice kit to use and has all the stuff for sepc bikes up until they change something else…

    I’d just jam an expansion anchor in there and then drift it out from the other side. Considering that you are painting it anyway, then you could use a little heat on the frame if it is being stubborn.

    The issue of not being able to do anything without having a whole forum tell you how?.

    You can tell by some people’s questions that they are gibbon fisted….
    Rather harsh, removing blind bearings is not a particularly intuitive task. I see where you are coming from though, one thread to ask how many bearings to replace, another thread to ask how to remove the bearings, I’d have waited for a 3rd thread asking whether to grease the faces or not before pressing in before ranting though 😉

    For someone who ‘knows they’re way around a tool kit’ It’s pretty simple.

    I only asked about how many bearings to replace as only a couple seemed to have any play in them so it was looking like it was more cost effective to only replace those.

    However it seems a better idea to replace them all in one go to prevent having to strip bike down again in the future.

    I’m sure once I’ve removed these bearing for the first time it will be a lot easier to do it again.

    +1 on both counts!

    There’s nothing wrong with asking some simple questions to do a job right or learn something.

    We’re not born knowing this stuff. While there are plenty of “gibbon fisted” (like that 🙂 ) people out there new skills can nearly always be learned. I’m handy mechanically but there are tools and fittings that you only learn about when you do a job for the first time and need them. I don’t sit home at night studying the machine mart catalogue just in case.

    My experience in life generally is its the ones who don’t ask questions and blunder on regardless you’ve got to watch.

    No, there’s the Axminster Tools one for that 😉

    Not necessarily if that tool kit does not include a blind bearing remover.

    Finding the solution to a problem not encountered before requires intuition/problem solving skills which one does not necessarily need in order to be taught the way around a tool kit and follow set procedures.

    gheez, a lot discussion over a simple and honest question. That’s what forums are for….to get advice and guidance etc. Chill pill people 🙂 No such thing as a stupid question.

    I don’t want to take it to a shop though.

    I want to do it myself hence the question.

    What’s wrong with that ?

    And nobeer don’t be bothered then.

    Right so instead of all the sarky unhelpful comments why didn’t you just say that in your first post ??

    Not one of your posts has been to do with the op subject they have just been about piss taking.
