Well the nut moved with some heat...

The single-shock bikes have a different fork. The big top nut secures onto a gold inner thread, which is a part that pushes up through the tube.

This is all a long way of saying that the inner thread is spinning when I try to remove it. Clearly I am supposed to use a very large allen key to hold the inner, and a spammer to turn the outer. But this is hard when you have just one pair of hands.

So nothing is broken here - looking at the parts fiche I can see why it's doing what it does. It's just awkward.

Unless anyone can think of a solution, I'll go back to the idea of a dremmel and chisel to split the damn thing off.

Been a while, but as I remember, it was a 17mm Allen key and a very large spanner. I used a very good quality large crescent wrench (Craftsman) that I tightened up by using pliers.
I've spent most of my money on women, motorcycles, and beer.
The rest of it I just wasted.

It's off.

I got a breaker bar long enough to brace against the frame, and a dirty great long spanner.

When it moved, it was a nice feeling.

High five! The noise it made when if first moved was a kind of metalic groan...

I've just bought a San Jose replacement yolk (triple-clamp thingie) to fit there in the next few weeks.
