After cutting the grass I decided I would fix my bike that I use for pottering about the streets on and have a look at the suspension bearings on my Enduro
Got the brakes fixed and everything pretty much how I wanted on my street bike, just need a few bits for it.
Then set about on the ENduro.
I have the great idea to take the shock off to check and see what size bushing I needed. I have now found out why there was so much play in the back end. THe shock busing bolt had snapped. Leaving half of it in there.
Bit of a bollocks really. I set about stripping the bike. Got all the bolts out of the frame, one of course has a bearing wedge on it. Which is really hand for extracting the bearing, just now it's stuck to the bloody bolt.
The rear bearings at the mech end of the bike. One screw comes out, the other just turns. Fantastic.
So
1. What is the best way to get that snapped bolt out?
2. What is the best way to get that bearing off the bolt
3. What is the best way to get the constantly turning bolt out of the back of the chainstay
4. Do specialized do replacement bolts for '04 Enduros.
5. ANybody got an XL 20" frame that they want to flog me. I can see this fixing the bike getting pricey.
[url= http://www.mountainbikecomponents.co.uk/contactus.asp ]BETD[/url] are the folks to speak to imo. They still do bearing replacements on the 04 enduro so would imagine they would various other bits to go with it. Then again I could be wrong.
I would soak the offending bolt with WD40 or another penetrating solution and leave it for a while, then have a go at it again!
Unless you live near Edinburgh, then I would advise giving the frame to me and I'll dort it right out 😀
Not that near, but near enough to do it if I pop up to see my folks in Jedburgh in a couple of weeks.
RIght pee'd off I was. I suspect that one that is turning is actually stuck to the bearing and has buggered the threads. Might be able to heli-coil it if needs be, but it looks too small.
Quirrel the problem you are facing is rust build up on the bolts axle, rust and other contaminants build up and sit up against the right angle created at the bearing / bolt interface.
This means that although the bolt can spin and rotate to the end of the thread, it tends to create an area of opposing force, that will push apart the two individual parts of the seat stay.
I see it all the time on frames that have one piece rockers with two bearings parallel to each other, the through axle binds at one of the axle / bearing race interfaces and loses it's capacity to fit through the race.
You have two options, give it a good seeing to with the penetrating solution in the hope enough of the crap will get dislodged or broken up or get access to the build up of shit with something and scrape it away.
Regardless of that, your best weapon is analysis of the problem, get a torch so that you can determine the amount of light and have a good look at what's happening.
Remember, you can always strip the frame and post the stuck bolt to me and I will sort it.
Good luck!
Any ideas on getting the snapped bolt out?
Let me see a photo of the problem and I'll tell you what I would do.

See a bit of the end of it on the opposite side

Would one of these work?
WHy is it not showing the pictures?
teh pictures are visible - screw extractors can work but in small sizes go very carefully as they can snap.
ANy other way of getting that out?
Would heating it up in boiling water make life easier? I presume the alloy will expand more than the steel bolt.
Found out that cycle store UK does bolt kits for 22 quid, which is significatnly cheaper than some of the 100 euros Ive seen this evening
Hey quirrel, why not just post that to me and I'll sort it out!
Probably your best option and I would love to have a go at that problem, dealt with similar issues bit never that specific one.
I would use a bolt extrator and just simply drill a small hole into the bolt.
Them bolt extractors seem to break off in the offending bolt more times than they work properly and they are harder than any known material so impossible to drill out
my first take on this would be to drill a hole thruogh from the visible end and tap a normal bolt thread in to it then when you tighten it up it will have the effect of unscrewing the stuck bolt
if that didnt work then I would try the extractor from the other end .
the heat generated when you drill the bolt may just weaken the bond a little .
if it all goes bad then as long as you dont have the bolt extractor stuck the it could be drilled out and helicoiled
or drilled out and a nut put on the end of a longer bolt .
