Viscous fan coupling W126


I need to change the viscous fan coupling on my W126 420SE. I have the part and was going to take it to my garage for them to fit but am thinking I might try to fit it myself.

Can anyone give me some advice on how to do this? It looks relatively easy to unscrew the 4 bolts and then put the old fan on the new coupling or is there a lot more to it than meets the eye?

Any info would be much appreciated.

No, that's about it. You may need to remove the fan shroud as well, but that's no big deal either.
