Hi! I am trying to fix the tension assembly on my friend's Singer 328K. The check spring was bad and one of the other pieces had somehow been all bent sideways. She bought replacement parts and had it all sitting there apart for a year. Now, I know how these things are supposed to go together on say, a 201 or 221, but the 328 has three tension discs. Do they all sit next to each other? And how do I get the check spring to actually be springy? It doesn't flex much at all. The next question is, how do I access the set screw to remove the assembly as a unit?

Thanks! I've been trying to find the service manual as a free PDF online with no success.

I don't know the 328 in particular, but some models have three tension disks to allow for twin needle and double thread. I found this picture further down on this page, hope it helps. The setting screw can be on the side of the head (sort of oposite side the face plate, to the right). The spring usually goes into a groove on the stud holding the entire assembly together, you have to test which one gives enough spring action for the thread.
