You need to be very careful with this job.
I made up a special tool set years ago just with simple workshop tools.
I have done fork seals on my own bike and several others.
I dismantle them by the “book” .
As in use the special tools to wind the adjuster clockwise down through the top cap.
Then slide the forks apart. This leaves the main damper units fastened in the bottom of the slider/lower.
Don’t disturb them if you don’t need to.
Clean out the grunge in the bottom of the fork.
One problem I have seen is that when you remove the top aluminium nut off the adjuster unit it tightens the adjuster hard into the cap.
This will make the special tool want to tear out the thin aluminium drives that the tool fits into.
Everything has to screw together easily for it all to work properly.
The parts must not be done up to any kind of normal torque settings.
Just nudge them up.
When you dismantle it the forks should slide off OK but when you assemble it with new bushes it may be a bit tight when you try to slide it on.
I have recently done it this way.
Otherwise you have to assemble the top bush, spacer, seal and clip after as explained above.
