Please Help Me Identify This Washer In Engine Rebuild

Hey everyone,

Can someone who has rebuilt their raptor 350 help me identify this below washer?

I found it at the bottom of my engine case after opening it to replace a crank rod. I can't seem to figure out where it's suppose to go. I tried looking at the manual but no luck.

The second pic shows the general size of it. It's about the size of the dowel pin.

It's possible the previous owner dropped it down there because it looks like someone else has rebuilt it before.

Thanks for any help.

Hey morphrider,

Yeah I tried a similar site called yamahapartshouse but no luck. However their diagram drawings aren't exactly clear enough to distinguish between washers.

I think I'll probably just end up making sure i am not missing any engine/transmission washers and call it good.
