I have posted A LOT about the tension assembly. In all of those posts, I have not shown how the check spring fits into the tension stud. So here it is. I have removed the tension assembly from the machine. To do so, find the set screw just behind the thread guide and loosen it. If you are lucky the tension assembly will pull out. If it is stuck, loosen it with some tri flow or LW (liquid wrench) and wait.
The parts.
Please note that the tension release pin must be placed into the stud as shown. I recommend that you do so AFTER you have placed the check spring, tension discs and thread guard on the stud. You will be less likely to lose it.

| tail of the check spring |
Sandwich the tension discs (flats facing eachother) and the thread guard in between the coil of the check spring and the eyelet.
Place this onto the stud so that the tail of the check spring nestles into one of the grooves on the tension stud. If the check spring has too much bounce, you must move the tail to a different groove. If it doesn't have enough, move it to a groove the opposite way.
(Don't forget the tension release pin. It must go into the tension stud before you put the indicator on.)
Next comes the indicator. Place it on the stud with the flat side next to the thread guard.
Now place the tension spring onto the stud so that the first half coil of the spring straddles the lower half of the stud.
Next comes the stop washer positioned on the stud so that the extension sits above the tension stud.
Now place the numbered dial on the stud positioned so that the Number 2 is oppositethe stop washer extension.
Compress the numbered dial against the spring as you thread the thumb nut onto the tension stud with the pin toward the numbered dial. Guide the pin into one of the holes on the numbered dial. Place the whole assembly on the machine, making sure that the extension on the thread guard fits into the hole on the machine. The presser foot must be DOWN when you out the tension assembly back on the machine. Position the check spring so that it rests on the extension on the left side of the thread guide.
Make sure that the + and - are positioned on top and tighten the set screw.
