Buy the time you've bought, all the tools needed, found a supplier for all the deals, it's cheaper to buy a reconditiond one, for about £150.
I made the only tool I need from the bits I had laying around in garage and got everything apart, posting pics later..
Whole point of this was to see how you take it apart with my spare compressor and to take parts for the one in my car so I don't have to refill the system AGAIN as I just did it today and that is how I found out the clutch doesn't work on my current compressor... What a bit of luck that I happened to put the broken compressor in the car and left the working one off...
EDIT:
Pic time!
Few pics of the tool:
Threads on the inside are the only part I had to make on this tool, it is some piece for plumbing or something I think.
With the clutch pulled off:
Everything I need off:
