Older Campagnolo BB removal - what tool

[Sampaj]

Hi everyone,

need some tool advice please

removed an older 10spd campagnolo crank from an older carbon frame. 
What BB removal tool would I need?

I believe a normal BB tool will work

[NISI]

Same tool as being used on a Campy cassette

[Sampaj]

I tried that - mines too small. Didn’t work

[NISI]

Shimano is smaller than the campag one

[Sampaj]

I tried - my campy tool doesn’t work

[openmind]

I don’t think that’s a Campy BB. An older mechanic  should have a splined tool in the bottom of his toolbox that will fit that. Try your LBS.

Others are correct, that's not a Campagnolo tool.

The tool you need looks to be the older style large-spline Shimano fitting, widely used before the advent of Hollowtech 2 external cups. Current Park Tool number is BBT-22 (which replaced the older Park BBT-2)

BTW, it's almost certainly not an ISO or a Campag taper BB, either, so I wouldn't advise refitting the cranks to it. It's most probably a JIS square taper which, whilst the taper angle is the same, standard, 2 degrees, the "starting" dimension is bigger than ISO / Campagnolo and the crank will not migrate far enough up the taper to be a good mechanical fit.

If it's a Campag crank from before 1994, the cranks will be pre-ISO and ideally (especially if they have ow been "over-stretched" on a JIS taper) you'll need to find a Campag taper BB. Refitting to the JIS axle you have risks the crank cracking or fully fracturing at the BB / crank interface.

I may not (probably won't) fail immediately but it may fail with use in the future. An early indicator will be creaking.

Fitting to an ISO axle is probably also a risky option as although the ISO & the original Campag tapers are almost identical, the Campag proprietary taper (which predated ISO) was fractionally longer and in many cases, an older Campag crank fitted to an ISO bracket goes too far up the taper and bottoms out on the square-to-round transition, putting a significant stress raiser in the "corders" of the square taper braoching in the crank, often leading to failure. We saw this happen multiple times in 2008/2009 with "Pista" cranks fitted to ISO axles when there was a fashion in the UK for fixies & the Campag Pista crankset from 1993 was fitted to newer ISO axles.

If it's a post 1994 designed crankset (at which point Campagnolo re-tooled, in common with several othee European makers, to suit the ISO standard taper, then you'd be better to find an ISO taper BB of the correct length, there are a few out there, it'll either be a 102mm axle (Record or Chorus) or 111 symmetrical. Campagnolo have both available ex-works, though availability in the market will depend on whether local wholesalers / importers have ordered them ....
