Vf500 final drive

Anyone recognise this washer
Stripped front and rear wheels for new seals and bearings
Found this but don't seem to be shown on any web site for the bike
I has placed it in the wheel as I think this is the only place ???

 

And it's not item 21 from the parts list

 

And I can't see anything from the front wheel seals and bearings that arethis size

 

Is it coated at all? Kinda looks like a bearing seal, they are metal coated with rubber.

 

Looks like a dust seal to me. Should cover the bearing face?

 

It's bigger than all the bearings it fit snug in the recess in the hub but I can't see why
It would be there and not on any diagrams very confused

 

And all rubber no metal.

 

When I did my 17 inch conversion I fiddled with the cush drive a lot. I don't recall anything like that.

 

Looks like there are some markings on it. What do they say?

 

Like you read my mind. GTS.

 

I had to GTS to find out what GTS stood for. Ya learn something new every day....
