removing a 3 piece crank??

Was wondering if anyone can help me.. how do I remove the sprocket side of a 3 piece crank set of this nature.. see the picture, thats all I can get off, I gather the other side is threaded too, as there is a piece that looks like you're supposed to thread off right behind the sprocket I think, its all round with a small flat area, but no wrench I have could ever fit in there, I guess you need a special tool?

PS: that other piece behind the sprocket is just a chainguard holder, dont let that confuse you.

PPS: I think these stupid threaded 3 piece cranks were invented to keep bike shops in business cause they cant be maintained with normal house hold tools and people like to complicate things!

Looks like you have cottered cranks, you need to get the crank side off before proceeding.

Try these links for info

Hopefully these will provide some direction. Is the sprocket side crank cottered also?
If so , you will need to get that cotter out and then can remove the crank axle, then cups.

Ok so that did it, and duh that was easy, now I feel like a moron. I've just dealt with 3 piece cottered cranks that you didnt have to remove the drive side arm to remove it in the past, anyways cool, thanks heaps!
