bernina 830 question
I have one of the original 830's and I need to replace the plastic gear. I have the gear and ordered what I thought was a repair manual (it isn't). I can see how to replace it except how to take the plastic housing off the back to get to the pin through the gear. Does anyone know how to this or where I might find instructions. I don't want to harm this machine. It has been the best machine I have ever owned.
Thanks in advance!!!
