Hi all
Kingpin change underway
caliper bolts (back ones) stuck solid and slightly rounded even before I started hammering away
Unless any tips I’ve tried everything I think it’s angle grinder time. Fallen at the first hurdle!

Yes it's salvageable, what's difficult to determine is how much time and effort it will take.
THe good news is you have plenty of bolt to get hold of.
Things to try:
1)Heat it up carefully, if you can boil it in oil and leave it cool in it before you get grips on the bolts.
2) Weld a nut on the top of the bolt stud, the heat may shock it. It also gives you something to turn.
3) Drill a pilot hole down the centre of the bolt, this allows a little shrinkage and may release it.
If it starts to move turn it "in / out" as you go, don't just attempt to wind it straight out. Penetrating oil or any thin oil helps at any stage.
Even after all this the threads could be damaged, you won't know until you get it out. Still options if they are (helicoil etc), but it could be cheaper to source a good used item at this point. If you can get a good one quickly for a few £ it not worth it, if you can't or they are ££££££ then saving it is your best option.
I would have a go, but that's just me. Good luck, Mike

Thank you!
Literally can’t be bothered haha, new one is £60 so just bought it.
Not sure if I can be bothered to do the kingpin the other side now this has been such a fuss!
See how I feel in the morning after some beer.
End of play today saw it all back together with new kingpin bearings and swivel seal (hopefully all done right!?) just waiting for caliper carrier tomorrow morning then it’s a late night tomorrow, hoping the other caliper is better to remove but I’ll be extra extra careful now I know how bad it can be

My standard solution is to heat it up with a blow lamp, get it good and hot then it might come out with a pair of grips. Or you could try a thread extractor.
If not, try drilling it out, use a small drill and work your way up, once you get over 3/4 of the diameter, it will probably just turn out. With a bit of luck the threads will be okay, otherwise a tap might be needed to clean them up.
New ones appear to be around £34, probably a pattern part, so you don’t have much to loose.

right.
Got myself a new fella for the caliper.
next question
when rebuilding, can I copper slip the carrier bolts and the pin bolts to avoid this happening again? I know there are some things one shouldn’t copper slip just wondering if these are they? The guide has their torque settings also.
then it’s onto the other wheel and hoping things are less grim. I’m going to try heat and patience before any angle grinding….
