Will be anti clockwise to loosen. And it will be tight.
If you're lucky there are some flats on the camshaft to fit a spanner or you'll have to jam the pully somehow.
Air gun might do it if you have the gear.
Currently in lancs dave's garage: Less rubbish now I've been to the tip.
Right, on reinspection there are two options I can see:
On the camshaft shown in one of the attached photos, there is a square section which could be used to brace the shaft. Is this wise inside the case?
In the other photo - I should be able to hold the pulley using something solid against the mouldings of the head (you may be able to see the marks where I've tried with a big screwdriver) or use some wire/rope to bind the pulley to the studs at the inlet and exhaust sides... is this too risky given the amount of torque that will be needed?
I'll use some Plus Gas at the same time.

Jammed an extension against the flat edge of the shaft and the head casing, perfect but, no matter how hard I tried, I could not shift it, even with a hammer. I'm about 19 stone BTW and I used all of it. Gave up. It's not leaking, was replaced maybe 20,000 miles ago, along with the cam belt, etc, when a couple of valves and the water pump were replaced. So I did the tappets instead. Have a new problem now...
The elbow connector which attaches to the water pump and the radiator hose snapped when putting it on the new pump. So brittle! Damned if I can find a part to replace it online.
