Hi Toby, it was good to meet you at last and see your xantia. Nice car!
Thanks for coming over and giving me the opportunity to assist - I have had an enormous amount of help from this forum and it's members in the past so it made a pleasant change to give something back.
(Although, you have to take the credit for popping the last cup in place before I got my mallet out.

)
I'm just glad the corrector hadn't seized but there was white grease on the mechanism so someone's been looking after it well.
It was interesting to note the retaining clip - though I can't fathom why it's just on one cup end and not both. Perhaps it's just to stop it getting lost when they do pop off?
I have to say though, I've never witnessed such a fast tick rate! Was it two or three ticks per second? I'd be happy to help you with that job too - it's all good experience to me.
