What tools are required to remove the BB?

Seweryn

Hi Guys,

What tools do I need to dismantle and replace the bottom bracket as on the photo below?



Thank you.

A lockring spanner is the only special tool everything else should be standard.

Thanks, I thought so . How to deal with the other side?

You'll need a crank extractor too.

Oh and a 10mm socket and ratchet to remove the crank bolts.

(I think it's 10mm, could be wrong)

Thanks, I have that. I assume it is a standard square taper (105 Shimano)?

I imagine so, yes. What chainset is on the bike?

Yep, but... some rules are made to be broken .

I assume I do not need one if I replace the BB with a sealed cartridge one?

Yes u will...u still need to remove the drive side cup. What's wrong with the BB? Unless the cups themselves are damaged, why not just replace the bearings and re-grease?

I am not sure, as I do not have the bike with me here (I keep it abroad and use it when I am on holidays), but I have a feeling the BB spindle (axle) is too wide to the right. I may be wrong, but last time when I cycled I remember the chainline was a bit out at the front. That may be the result of the rear wheel axle being 126mm, while the frameset is 130mm standard. I have a new set of wheels though, so that is going to be sorted. Not sure how to determine if the width of the BB spindle is correct.

Is the chain falling off? Do the gears not work?...."if it ain't broken, don't fix it"

P.s. Looks like a really nice bike!

No, nothing like that, all function reasonably well. The new wheels come with one more sprocket cassette, so I am also looking for 8-speed downtube shifters, but that is another story .
Just want to make sure that all is the way it should be.

For that model 105 chainset (FC-1050) the bottom bracket axle should be 115mm as its an Italian thread / frame. 113mm if English thread. Next time your over there remove it and measure it.

For what's it worth, the space on both sides of the bottom bracket shell looks right to me!

Surely the shifters can't be hard to come by?

Down-tube shifters are not indexed..just friction, so sprocket numbers are not relevant.

Well, yes and no. I have been looking for them for a few months now. There are some on eBay at present, but for mad money. I bought a set recently, but it turned out they were 7-speed . Will get there finally...

They were indexed when SIS was introduced in c1988!

You could switch between an indexed and non-indexed option with Shimano from that year. I had a set of Ultegra ones.

The ones on the bike are indexed actually.

Sorry - just saw you want 8 speed and a quick search on ebay just brings up 7 speed. Are your sure your rear mech is also 8 speed?

The current shifters and the cassette are 7-speed (Uniglide). I have a new set of wheels with an 8-speed Hyperglide cassette, so I need 8-speed shifters. The rear mech will stay as is, and it will work as 8-speed (or it should, I believe).

Oops! Showing my age! The last bike I had with down tube shifters certainly weren't indexed...

They were like these:

Thanks, but Campagnolo is not compatible AFAIK (different spacing). The other ones should work. .

You could get Shimano Sora SL-R400 8-speed down tube shifters or Ultegra / Shimano 600 ones, which are period correct.

Thanks, I was mainly looking at the 7402 DA Shifters, but found out they are unreasonably priced. The 600-series were all 7 or 6-speed. Will check them again.

You want 6401 - which is 8 speed.

May also be rare though.

Perfect, thank you. That should help .

By the way, I realised there are 8-speed shifters here for sale:

http://www.chainreactioncycles.com/ie/en/shimano-tiagra-r400-8-speed-down-tube-shifter/rp-prod13671

Would they work with my derailleur?

I would think so - had suggested them previously.

Chainreactioncycles have a 365 days return policy also which may be useful!
