 Posted: Wed 7/Nov/07 1:11pm Post subject: Help With Broken Headset |
  |
|
The rubber cages that hold the bearings in the top/bottom parts of my 'fsa impact' integrated headset have split - the top in 2 places and the bottom (which is pictured) in about 6 places.
I thought I could just get rid of the cages and pack them with loose bearings/grease, but I went into the bikeshop for a second opinion. One shop told me that loose bearings wouldn't be a good idea and that I needed to replace not just the cage but the whole thing, but then a second shop said loose bearings would be fine.
So I didn't know what to do, until i realized that there must be heaps of bike mechanics that come on here, who posibly have come across this before and could give me some advice, any of which would be really appreciated.
Thanks
Chris

loose bearins are all good as long as there isnt a too bigger gap when all the bearings are pushed together. if you can find enough bearings you'll be set

Wide open have some FSA spares, might be worth your LBS giving them a call, I've gotten crown races and things thru them before

is that actually a cartridge bearing (cos that looks more like the lower 1/2 of a cart they're sitting in than a headset cup).
anyway, if you want to put loose balls in no real problem - just remember to leave at least a 1-ball width gap. Going to be a pain to put together is all (espec the lower) - pick a really sticky grease lest you like the sound of balls raining down
can't find the impact in the FSA headset book, but FSA only uses a handful of different bearings across the different models, if you can find the model no. on it you should be able to get replacements (though quite often it's cheaper to buy a whole headset and nick the bearings than just a bearing kit)

Thanks the the replies. That part in the photo sits in the frame, and then another part sits on top of it, I don't know if this counts as a cartridge or not. I know very little about this sort of stuff. I have plenty of loose bearings the same size so I'll try packing them in with grease.

woudn't it just be easier to wander into a bearing shop with the cart and get a replacement?
I've use loose bearing headsets before, it's a basdrat when it comes to rebuilding it or chaging forks..

Loose bearings would be preferable as theirs no cage to break. I won't be taking it apart/changing the forks very often so that won’t be an issue. I just wasn't sure if there was any reason the cage was there, apart from ease of assembly.
Unless I can work out how the cage broke in the first place, another cage will probably break again anyway.

actually the cage being in pieces isn't a huge prob - as long as you can get it all back together after cleaning you could just leave it as is. Question is really what kind of nick the bearings are in - if they're rough and the cups are damaged it's whol cart time
have a look on the outside of the lower cup - it should have some numbers printed on it (which will tell you what the replacement should be). About $35 for a pair of new carts (if they're the low-end th-823 'servicable ACB' here's your chance to upgrade to the TH-873 sealead cart)

It says on the side 'TH Industries 1-1/8th" 45x45 NO.8B ACB Compatible W/Campy'
The bike shop told me each one would cost $20-$30 to replace, which together would be more then i originally paid for the headset. The bearings don't look like they are in too bad a condition, I've only had the bike for a few months and haven't had much time to ride.

yep - afraid they're right, which is why I stocked up on cane creak s8's when they were on silly special (since I got whole headsets for 2/3 the cost of the bearings alone)
it sounds like it's the th-870b 'two part servicable' bearing - if it's still smooth just clean it, and shove all the bits back, it'll be fine as is, the rubber cage being in pieces doesn't matter

it is the 870 bearing you need. and they do cost 25-30 each to replace if you go to a bike shop and get them to order the replacements from WideOpen (who carry these bearing spares).
another option (also mentioned here) is to take them into somewhere like SKF. But I suspect they will cost about the same there.
Two bearings, $50 = headset that will last another X years. As far as bang for buck bike parts go I'd say that was rather good.

we pay FAR too much locally for 'consumable' parts like this!

then again you could buy a whole spare headset for US$33
