Tension disc assembly - sewing machine

Question

Hello! I have a Super Deluxe Zigzag III (I think) sewing machine. While working on a quilt today, the tension disc assembly popped off! There are 3 pieces...the dial with the numbers, the housing that fits into and a spring with the tension guide thing you put the thread through after placing it through the tension discs. I cannot for the life of me figure out how to get it back together properly. The instruction manual of course doesn't mention the assembly. Can you help?
