It's possible that in disassembling the freewheel, jawai thought he was following the procedure to remove it.
jawai, whether you meant to or not, you disassembled it. At this point, it will probably be too much trouble to reassemble it. I've done it about twice, and I don't think I would do it again unless I was desparate.
So do as DarLasse74 says: clamp it in a vise, ruining it. Turn the wheel counterclockwise. You may have to turn really hard. Keep turning. Next, buy a new freewheel. A freewheel is a combination cluster and ratchet mechanism. Older bikes have them. Newer bikes have the ratchet mechanism built into the hub and the cassette of cogs slides off.
Follow the procedure above, next time you need to remove the freewheel. I.e. don't disassemble it.
Yesterday, I removed a freewheel from a 30 year old Schwinn Varsity by putting the remover-tool in the vise. I was grunting very loudly by the time I got it free. And I had a 27" lever (the wheel)!
