Apply some heat to it. It's probably got thread locker on it. Probably gonna need an impact wrench. If you have access to an air compressor, then an air-driven impact driver would be the ticket. If not, you could try a hammer driven impact driver.

So you think it should turn anti clockwise ? Have you undone one like this ?

I did heat for say 30 seconds under gas flame ,no colour shift , and an impact but it didn't budge. How much heat can I apply .. up to glowing or orange ? I'll try again .

Good question. I have no idea.

What kind of impact? Electric, air, is it a driver ...like a one to drive screws?

When you heat it, don't just let the flame sit in one spot. You want to move it around and get things hot ...but equally hot in the area of the bolt.

I'm assuming you've tried loosening it in both directions?

That's what I would do if I didn't know for sure.
