I've inheretted from a friend a lovely 1980s Gitane with full Campag groupset.

However years of neglect has seen the dreaded orange spots cover everything. I'm trying to overhaul but have fallen fowl at removing the crank arms.

I've got two crank extractors and niether of them seems to fit and I've managed to strip the first few threads off one of the arms.

Do I need a special Campag only crank extractor?

Anyone had any joy trying to get arms off with a home-made crank extractor?

Any help would be hugely welcome, I don't want to wreck anymore of this bike.

Cheers,
1981

    Some of the early campag cranks used a different sized thread.
    You could try a ball joint splitter but it will probably mark the cranks.

    Some Campagnolo cranks use a left-hand thread on the crank extractor. A fork-type ball joint splitter might be necessary - try an auto repair dealer.
    Make mine an Italian, with Campagnolo on the side..

    Thanks guys, ball joint splitter purchased – I'm going to pack it with wood each side so I can hopefully minimise damage to the arm/bb ...

    Right, I think I'm into destructive options only.

    Tried a crank puller, stripped the threads in the crank arm.

    Tried a ball joint splitter, nothing moved and permantley marked the cranks.

    Tried a three armed puller, still nothing and more marks across the cranks.

    So, I think I'm into cutting the crank arms and splitting them with a cold chisel.

    Questions is, is there anyway to know what level of groupset this is, just by looking at it?

    It's from a 1980's Gitanes and has a weird fleck matt finish?

    I don't want to permanently destroy something, if its expensive.

    Thanks again for any help.

    If you search online - www.campyonly.com and www.campyoldy.com are good places to look. If your parts are Super Record they might be worth saving, but others less so - generally materials and finishes on bike parts were less durable in those days - relying more on the elbow grease of owners to keep it shiney!

    heat up the grank with a blowlamp for about 4 or 5 minutes-aluminium has a higher coefficient of expansion than the steel axle so will expand (and loosen) more

    this should work as its based on SCIENCE!

    Take it to your LBS.
    They should have special tools to pull your cranks off even if the threads have gone.I know we have a VAR one which works in this way.
