Well, Mr Haynes has some suprisingly good pics for a change.
It looks like its a gearbox thrust washer ... and there are 7 of them, so I've no idea which one.
At least from racing experience, if it was a 'bad' one to lose, there would be bits of gear teeth to show as well, and there was no other significant debris, just some magnetic sludge to show something is wearing ...
