I take it you have all the circlips? And some decent circlip pliers?
I used some really rubbish ebay circlip pliers with swappable internal/external bits and they were a nightmare to use.
So, I bought some decent circlip pliers and the tips were too big to fit into the holes in the small circlips. So just make sure you have some circlip pliers that fit! 😀
Other things worth having – lots of kitchen roll to clear up the oil, something to catch the old oil in, IPA spray (optional) to help clean up the internals properly (Maplin sell it), a dowel or similar rod to prod kitchen roll into the fork lowers (again optional)….
Take your time, make sure you keep track of the order that things come apart in, the lowers can take a bigger whack than you expect to get them to separate from the internal shafts and read through the tech manual a few times so you know mainly what you are doing before you get covered in fork oil…….
