http://www.tfsr.org/publications/tec...achine_manual/ then look at tension mechanism. There are only a few ways those can go... You may have info in your user's manual...

Well, you already have the tension off. Just turn the set screw loose in the side of the machine with the harp. Put the tension where you want it and set the screw back the way you want it. You'll have to make sure the spring is right in the whole process. Do look at that tfsr publication. It helps me to have it in my face when I'm re-assembling.
Iris and I ran into fun when we did the 319 on Friday - the dumb 319 manual was not matching up with the order we took the thing apart or the logical way it should go. It had the flat disk between the two curved disks. It came off last so we put it back on first. We had a dickens of a time with the spring. You have to hold it just so and hold your mouth just so and have an extra hand or two and try it 5 times and it will go back together. Some times they go back together on the first try - mostly when you aren't trying to teach somebody... Oh well, Iris needed the practice. I bet she can do it in her sleep.
