Identify this YZ seal

[Woody]

I'm slowly putting my YZ125G back together. I thought that I had a good handle on what goes where and took a few pics when I dismantled her, but I can't find out where the seal in the right of these pics goes. It was amongst my box of swingarm pivot and rear axle bits & pieces. The thin washer on the left goes inside the left hand side swingarm thrust cover and interestling enough the right one doen't have one.
i can't seem to find this seal in the parts book.

Main seal  . Split the cases and have a look .

(How the hell would I know . Put the famous pen in the shot and we might have a wild guess ).

Woody ol mate...Go to yamatopdog.com and click on yamaha online catalogue ( in red near the top centre ) and punch in Step 1 ..Motorcycle... Step 2... 1980 ...Step 3 ...YZ 125 G
If you think it`s swing arm click swing arm on the left hand menu and zoom in to look for it...part numbers are underneath...if its steering go to steering

Good Luck

That seal looks like the one that goes on the rear axle spacer on the left side of the wheel (covers the bearing etc)

And the winner is - 'Cyclegod'

thanks guys, it gets very hard to tell the shape of some seals & collars etc from the parts book.
