Anyone know how to remove the top cover of the hatsuyuki hf-500e. I took out all the screws that I saw. Unbolted the crank and the tension adjust knob. The only thing i can't remove is the ice block holder knob in the middle of the machine.

Reason is I keep getting a knocking sound when i run the machine, only when on the lock position. on free no sound, lock (even with no ice on the machine still same knocking sound.) I looked in and it's coming from that knob and the worm gear.

Anybody got any ideas on a fix or how to remove that top piece.
