I have just purchased a nice pair of Corsa Record Cranks with the four arms and one tucked behind the crank. My understanding is that in all versions of this crank the extractor threads are reverse and you need Campag's reverse thread crank extractor tool. Fortunately I have one but neither it or a conventionally threaded Shimano extractor will even start. I am assuming that some one has butchered the extractor threads on both cranks by jamming in an inappropriate extractor tool.
I do not wish to fit the cranks without some means of removing them in the future so it seems I have two options. Get the threads remade some how - is there a tool that will do this ? - or is there a way to remove cranks without using a conventional tool ? Some sort of auto hub puller might work but its sizing would be critical I would think. Does anyone have any experience of this or an alternative solution ?
Thank for your thoughts.
