One point not mentioned in this thread is this:
When you are re-assembling the fork and installing the blue Fork Cap onto the damper rod
1- Make sure the grey adjuster plate is able to turn freely inside the Fork Cap.
2- Then make sure the four splines on the damper rod are properly seated into the grey preload adjuster/spinner that is threaded inside the blue fork cap itself.
To do this, as you lightly put the Fork Cap onto the damper rod, rotate it until you feel those splines line up with the notches in the adjuster plate and the fork cap will drop down a bit more onto those splines.
In my case, due to the manual's lack of proper detail on the new forks, during disassembly I had turned the preload adjuster all the way Out/Soft with too much force, and got the inner preload adjuster plate jammed up against the inside of the fork. When I got the forks back together, I couldn't move the preload adjuster nut. I had to take the caps back off and free up that inner adjuster plate on the threads and then re-assemble again.
If this isn't making sense, check out these pics showing the parts involved:
Inside the fork cap - note the grey colored adjuster on threads inside, with four notches
Rebound / top of Damper tube - note the four splines that seat in the notches in above pic
Hope this helps.
