Topic: Mystery Washer!

[Dreyzar]

So I've learned a lesson in not letting a project sit on the bench too long. I pulled the clutch out of my cb500 about a week ago and only now got around to putting the new one in. I've put it all together and I'm looking at a washer 28mm OD, 18.4mm ID, 1.6mm thick. Its got the look of something that came out of the motor, browned with oil and all.
But I can't for the life of me figure out where it goes!
There's a polished-from-wear surface 22mm in diameter on one side, so it seems like it was 'doing something.'
Any ideas?
Its vaguely possible that it got mixed in with my clutch parts from somewhere else, but I seem to recall taking it out of there.
I'd be quite grateful for any insight.

looks like it goes on the shaft before the hub goes into the basket.

I would think #12 in the diagram is what your looking for.

Thanks for the suggestions.
Sadly the ID is too small to fit on the shaft (which is 25mm), and #12 from the diagram is already in there. The washer fits quite nicely onto the kickstarter shaft but wouldn't seem to serve any purpose there.
I'm getting close to putting it together as is..

It may control end play, on kicker shaft..

#12 is a thin shim,the kicker shaft sounds like the culprit if it wont fit the clutch shaft

Indeed, the parts diagram shows a washer outside the circlip on the kicker spindle. Thanks a bunch guys!
