Help please. I have a Singer 6038 sewing machine and the kids took off the needle thread tension dial and I'm not sure how it goes back on. There are 4 metal clips, a spring and the dial itself. I'm just not sure in which order the 4 metal clips go back in there and which way they need to face. I have the instruction book but it doesn't have any information on how this goes back together. If anyone knows how they go on or has a good repair diagram link please let me know. I really don't want to take the machine to the repair place just to pay someone money to screw the knob back on.
