Thanks for your replies, very helpful. You don’t think the left handed drill and extractor method is worth a try then, as that was my only other suggestion, other than welding a nut on it, which you can’t do now. Still, I suppose you’ve had to get round similar situations on aero engines plenty of times. Getting comfortable with decent access is half the battle as you no doubt know only too well.
I changed my clutch cable a couple of years ago, purely as a precaution, but opted for a very expensive oe item. I’ll certainly consider the clutch arm mod, as having broken a knuckle on my left hand 2 months ago, it’s far from pain free. Going for a whizz on Friday as the forecast is good, to see if it’s going to be much of a problem or not.
Good luck with the stud :thumbup
