I have bought and old late '80s Vitus road bike and am stripping it for a 're-group' My Shimano chain bolt cup removal pin tool doesn't quite fit it.

Can anyone confirm if these early chainsets were allen bolt removeable or whether I need to get these dust caps out and the bolt off to fit a crank removal tool.

Basically I need to get these cranks off as I've sold them to a collector for spares and would be interested to know a bit more about them for removal purposes and possibly where I can source a suitable pin tool if I have to take the dust caps and crank bolts off first.

thanks - any/all advise appreciated.

Self-extracting but a really stupid size hex socket.

i think campag is 7 or maybe 8mm
the allen head looks rounded off anyhow. you can remove the self ext'g bolts with a hammer and punch or hard nail. Put the punch in the holes and tap it out anticlockwise, then get the bolt out. If its too rounded, hammer a tight torx bit in and undo. then use normal campag chainset fixing bolts when refitting

Thanks for that everyone - I can confirm hex key is a 7mm, fortunately I have a good one in my car maintenance kit (weird size though). The dust cap pin spacing is not Shimano peg spanner spacing (also irritating) I could do with a decent fine pin nose plier to get to those. [Mental note to self] - do not buy a bike with a Campag group - or I'll have to re-tool - as everything seems slightly different (bloomin' Italians, and usually I'm used to saying bloomin' Japanese).

I've lubed-everything up with fine penetrating oil tonight and will have another go tomorrow. The chainset has to come off as I'm fitting a period DuraAce group set to the old Vitus, as Campag is not my thing (pretty as it is), so I've sold this part and need to get it off carefully without damaging anything). I will try again tomorrow to find out whether the bolts are self extracting. To be honest I will be very suprised if they are as these Campag.Victory chainsets date back to about '87 and I wasn't aware anyone had invented self extractors until the end of the '80s with the likes of 'Zero zippies' and 'Syncros crank-o-matics' I spotted on the MTB scene at the time.

It is 7mm, and these are self-extracting bolts.

You're much better off using the self-extractors if you can. Campag's C-Record self-extractors use a left-hand thread, and I'm fairly sure these do too. That means that if you can get the caps out, you still need to source the special Campag left-hand-threaded extractor.

They were fairly common on Shimano cranks in the early eighties:

Wow - I'm impressed with that - you learn something every day. I will have a go at crank extraction with a bit more confidence knowing more about these early cranks now. I suspected it might be a special Campag. puller needed without the caps to. I am relieved to learn the dust caps double as pullers and suprised early 80s road cranks featured this technology - but thanks its all good info. guys, I am grateful to all that contributed to my question here. Thanks for reading and advising me.

I believe Shimano did already had these selfextracting BB bolts in 1980 on Shimano 600 (arabesque pattern)

If it's Victory, I'm pretty sure it's a standard RH thread for the crank extractor tool - I dismantled a bike last year and removed a chainset and I certainly don't have a LH thread crank extractor.

You could be right. I had second thoughts after posting and did some research. The 18bis Campagnolo catalogue lists the same part number for the Record and Victory self-extractor: part 2350001. See page 40 of this pdf:

http://www.classicbikeparts.de/z-catalo ... %20bis.pdf

That's a left-hand-threaded part:

This one looks a lot like a right-hand thread though:

http://picasaweb.google.com/10988273921 ... 3917741522

It's not impossible there was a running change, just as there was with C-Record. Something to watch out for. As far as I know, the similar Triomphe cranks always had a standard thread.

In case anyone is in need of a left-hand-threaded crank extractor, Campy Oldy lists them in stock:
