Question

I loaned to my friend my White sewing machine #1418 and she disassembled tension dial by accident. I need to re assemble. Anybody have schematics? or suggestions?

Hi ,I own a Janome Combi 10, and I've foolishly taken the tread tension dial off. Now I can't put it back on!Can you help please? I've also included a picture of all the tension dial parts.Thanks, Carrie
