That's more than a dust cap, it's the self extractor for the crank. With
that thing in, unscrewing the bolt in the centre will pull the crank
off. Without it it'll just remove the bolt but leave the crank there.

I think they're threaded the same on both sides, so you should be okay;
just don't lose the other one...

I haven't worked out a really satisfactory way of tightening the things.
I use the end of a screwdriver (or key, if I'm in the middle of nowhere)
to push them tight. Presumably you can get a special gadget to tighten
them properly...

Incidentally, 'IrfanView' (http://www.irfanview.com) is a very nice
little program that will shrink pictures down so you don't end up with
almost 2MBs of pictures in a thread...

I put a piece of spoke in each hole (as they fit well), then lever them
round while holding the ends of the spoke offcuts.

if i have a crank extracter tool then i should still be good right?
just unscrew bolt, then use crank extractor as i normally would with a
square tapered crank...

Nope. I have the old onza, and I lost the dust cap on my
non-crankgrabbing crank, too. The dust caps are reverse threaded, so a
normal crank-extractor will strip out your cranks. Also, the tool for
removing the dust caps is called a spanner wrench. I don't have one, so
I use a hemostat (aka roach-clip for you stoners out there), or small
scissors.

A note for all you onza owners: I have the old Onza, and when I took
apart the cranksert, I found the bolts were tightening on the splines. I
put a washer in there to rectify the problem. I reccomend you do too. It
only makes the bolt stick out an extra 1/8". Also, the hub works like
the profiles. Don't fully tighten the right crank, alternate. 1/2 turn
right, 1/2 turn left... That way the axle stays centered in the hub. If
you do one side completely first, you can pull the axle out of the hub
(I'm not saying this from observation, but sadly, experience).
