Spring o-ring

Hello everyone,

Looking for help on a piece found while dis and assembly of sprocket and gear shift cover.

The thing is a size of a dime , looks like a o- ring but looking closely it's a o ring made of metal spring.

I removed the wheel, chain, sprockets and the cover to replace the leaking seal that the gear shift stem/shaft goes through. Did remove some other things that was behind the cover for a looks-see.

Is there anyone familiar with this spring o-ring thing?

My bike is a kz750g twin
Much obliged

Came off a seal?

I don't know whether or not this seal is the type that contains a spring.

I believe such springs are intended to produce a tighter grip by the inner diameter of the seal onto whatever component fits through the seal.

The part number for this particular seal is 92051-005.

Good Fortune!

Thanks for the quick response, most likely from one of the seals now that I know there is one inside. Will check tomorrow.

Thanks again.
