How do I get the old oil out of the headstock?

It's not in the oil, but it does get quite a bit splashed on it when the lathe is in use. The oil splashes pretty much everywhere in the headstock... More by luck than judgment, I managed to fill it exactly to the right level, so I'm pretty sure it's not over-full. Apparently, it's an easy device to adjust, although I couldn't tell you how from just looking at it.
Darren:
I suppose you have put the lid back on now, but a picture might help to see what type it is?
AdeV:
My wish is your command :bow:
Here's three shots of the clutch, showing it disengaged, half-engaged (slipping) and fully engaged. Although when disengaged, it's also slipping somewhat. Click on the pics for the larger version:
As you can see, the slider moves from right to left; compressing what looks like a normal clutch pack on the LHS. Here's a few more closeups which, hopefully, show some of the other details:
An overview of the headstock. The clutch is in the far left corner, looking from the front of the lathe.
I have a bunch of toolpost questions too, but I'll open a separate thread for that one.

Nuts and bolts don't just grow in an oily environment, the only place they are liable to have come from is the metal contained within the box.

I found a place for one of the grub screws; appears to be a set screw in one of the first motion gears. The gear was still firmly attached to the shaft, however, by at least one more "thing" (I'd say grub screw, but it looks more like a badly made rivet), and possibly a second one. Nevertheless, I've screwed the screw back in, and it doesn't seem to have had any adverse effects (or, for that matter, made any difference at all). I can't find anywhere where the mangled second screw might have come from, which just suggests that it's underneath something else & I can't see it.
Darren:
I doubt it's from underneath as it needs to accessible for assembly. Just a hunch.
The clutch seems to be two serrated plates pressed together for engaged. They should come apart to dis-engage.
I wonder if that has anything to do with the bolt you found?
