Same thing happened to me, and after making a lot of the same inquiries(including to clock repair shops,) I decided to open up a an old gear box to check gear sizes. Well I got lucky as the reducer gear was same size and only simply pressed on. I have no idea what game the salvaged gear box was off, but it did confirm that it can be found in other machines. Sadly, Not sure there is a cost effective way to pursue that remedy, unless you have the spares and can pop them open. Additionally, I thought I just saw a whole dead world motor assembly for sale, even had a pic. I'll scrounge around my history and see if I can find it.
