Cal, I did find the chain and cam gear. We've been recycling now and Kitty really is enjoying it. So she had the chain and cam gear in the metal can. lol At least she knew where it was. If you want to check on the crank gear for me it would be much appreciated. Let me know the cost for the gear and shipping. Probably be pretty strong from Australia, but I have not found separate pieces here yet. Thanks Cal.
