I have done a few of these...
Pull the drawbar and take a measurement of the total stack up length at compression, write it down.
I lay a big piece of cardboard out to draw on. As you take each washer off take note of the concave/ convex side and draw it's orientation on the cardboard, your essentially making your own blueprint as you pull each washer and denote the concave/ convex side. when your done it should look something like:
))((()))(()))((())) etc...When you have all the washers back on tighten the nut until you reach your stack up length that you wrote down initially and you should be good to go. We did grease each washer during reassembly also.
There is no manual that I know of for this info.
Good luck.
