2500 Viscous fan question

[Keith912]

Hi, I have this fan on my spares car but it does not seem to be the one described in the workshop manual No centre fixing bolt and a strange tab which holds in a tiny pin? I was hoping an easy swap to my other 2500. Anyone recognise it?

Ah, thanks for the reply. I can see the big nut behind but can't see how you stop the water pump to get the coupling to unscrew
