EXUP cables replacement

[Davebo]

So, having been told I have a snapped EXUP (inner) cable I've sourced a repair kit from Venhill.

I am assuming that I can replace the inner cable without having to take the whole valve assembly out, but I cannot find any documentation of the top end of the cables and how to remove them.

Any clues please ? Tips & Tricks ?

TIA, DBo.
