I did a clutch fluid flush and found a part loose in the reservoir. Turns out it is part #8 on the parts fiche called “protector”. I didn’t put it back at the time as I had no clue where it went. Is this a necessary part? What’s it’s purpose?
 
Without looking at the fiche to see what you are talking about - a picture would have been good - I imagine it is the little "baffle" that sits over the port on the bottom of the m/c. Keeps the returning fluid from creating too much splashing inside the m/c.
 
Here's a picture of the part in question - it is for the purpose that Bush & John Heath stated, to prevent fluid from splashing upwards into the eyes of the person doing maintenance when the cover has been removed from the master cylinder. It covers a small hole called a 'compensating port'.

I have always thought that there must be another reason for the existence of this part other than protecting one from themself. In my experience design engineers don't spend much effort trying to protect service personel from themselves as there is the assumption that said people should know what they are doing. The danger of brake fluid spraying about can be eliminated by simply sitting the cover loosely on the reservoir so it is not a case of an unknown or unavoidable danger. What that other reason might be is something that I haven't come up with however.
 
Yup the first squeeze of the clutch handle let me know I was up for a fight ;) Thanks for the responses everyone, I think I'll just hang it on the 'extra parts grave yard' wall.

I believe that it is a friction-fit (press in to fit) component, you might be able to put it back into place using a pair of tweezers or needle-nose pliers with an offset at the end.
