Campagnolo sealed BB servicing

Greetings to the forum !

Any idea where I can find instructions/video on how to service a Campagnolo Square taper (i.e. older version) sealed bottom bracket.

Like this one:

I am trying to get rid of the clicking in my bb.

I took it out last night but could not figure out how to clean and regrease as it is completely sealed.

Cheers

think you may have answered your own question these, as i thought they were completely sealed and non serviceable..

not expensive to buy new

Thanks for getting back.

I may want to upgrade as well. I am a fat ass (110kg) and I get this clicking noise from the BB almost on all my bikes after a while.

Was thinking of the Chorus 10 speed ??

Also noticed some options from other brands (Tifo/ Token). Any experience with those??

for your generosity of mass, i'd advise sticking with a reputable brand such as campagnolo

tifosi and token utilise much lighter alloys, and your ahem, power, will destroy them quickly

You can't open a sealed BB

Slightly offtopic
Is it just me? Or do BB get damaged over time when skidding?

Well my BBs get damaged even on Freewheel bikes, I think its the amount of abuse they take. I managed to destroy:

The shimano sealed BB that came on my modern Binachi Hybrid
2 Campy sealed BBs same as pic above on my 2 road bikes
A cheap generic BB on my Falcon 10 speed

It starts as a clicking noise which becomes louder with time.
