Supercharger Replacement - DIY removal and refitting

I need to replace my Supercharger and having just sourced a reasonably priced second-hand unit I am looking to save even more money by doing the replacement myself.

I know which end of a spanner does what and I don't mind devoting a whole weekend to the task, but I'd really prefer to follow some instructions rather than just muddle my way through.

Can anyone point my in the right direction of a "How to" guide or a sticky? It needs to be model specific obviously, but I really just need to know which bits to remove and in what order.... along with some tips about difficult tasks ideally.

It must be a job that's done quite often to replace / upgrade the pulley so I'm hoping there's something out there......
