    This bolt is stuck in hard. Other than Plus gas, heat and a good hammering does anyone have any advice on getting this fella out without destroying all the bearings and spacers?

        A soft steel drift that fits the hole in the end of the bolt (nut/thread end) will help prevent the end mushrooming over when you belt it. Try and get it turning first. Heat. Lots of wd40 . Use a big lump hammer with big decisive wacks. Not loads of hits with a little hammer...

          Thanks, it's all plusgassed up and turns anyway (i guess it's locked up to the bearings) so I'll try to find a suitable drift and get whacking.

            Yeah. There’s steel bushes inside the bearings. The bolt will rust to them if not well greased on fitting. You could try putting a lot of hot water through the centre hole of the bolt but I doubt it’ll get enough heat to where it needs to be...

            Big hammer, big clean blows 👍 maybe put a sacrificial nut on the end of the thread for extra protection...
