I've searched this forum and the Web trying to find the order of the parts on the fork damper tube, zilch! Absolutely no breakdown of these parts, seems Yamaha added these parts after they wrote the manual.

I think the parts go in the order I've assembled them, but two questions remain:

The round aluminium rings, circled, with the holes in them are different on each side, which way is up???

And more perplexing, the two steel stepped washers circled, where the hell do they go, I can't find anything they fit over???

The last bits look like typical washers that ride atop the springs. The rest is unfamiliar

I took a picture of the guts on my 1974 TX-A (post #46 in the link above) They look the same/similar to yours . Hope that helps.
 
Figured it out, as Gary said the steel washers go atop the springs.
The wave washer goes in the smaller circle on the aluminium damper ring and the aluminium washer with the protuberance fits inside that. The steel washer with the holes goes underneath that assembly and the large steel tube buts up underneath that. If you examine the large steel tube, it has a chamfer on the inner circumference, that chamfer aligns with the holes on the steel washer.

Your link doesn't work.
 
Interesting.
Looks like Yamaha got really serious about damping in those years, then said F-it no one notices anyway, and went back to a tapered seat and a couple holes, done.
