How to disassemble thread tension regulator

The thread take up spring is the next detail that influences on the quality of the sewing stitch.
It should move away with a little effort.
But first you need to look at the tension stud on which the tensioner parts are put on. After many years of constant work the thread during the running place can make the grooves on the surface of this pin. These grooves can cause the loops in the seam to appear and the upper thread breaking.
If grooves are, you need to delete them using a small file.
Notice how the tension discs are put to each other. They should not be put in one another.
