Put back together a tension knob on a necchi - Necchi 3102 Mechanical Sewing Machine

Doing a google search for the brand plus model number for a user guide or YouTube videos might find what you are looking for. That it is a Necchi doesn't supply the model number and of course models differ. On a 537L model, the large knob on the right side about halfway between the top and bottom of the machine adjusts stitch length. The numbers may range from 0 to 5 with 0 meaning no length and 5 being the largest length. Tension, stitch length and stitch width are all controlled by small dials on the front of the Necchi machine. If your stitch length is set to 0, the sewing machine will not feed the fabric. Incorrect tension will cause poor stitch quality. You must consult you machine's user manual to know how to adjust the tension as the procedure differs among machines. Here is a general guide, however:

How to Adjust the Tension on Sewing Machine

thread is not between tension plates but behind one

Oops! All sewing machine diagrams/manuals are available, online. Oddly. From the late 1800's, on.

Sometimes the cotton is too loose on the bobbin; check this first then try putting the bobbin in again making sure you have threaded it in correctly, hope this helps

Do you mean the Tension adjustment knob? If that is the part you need then try this site: http://vintagesewingmachineparts.com/necchi-535-fa-tension-adjustment-sewing-machine-part-3/ .

There are also several sites that have parts for sewing machines but do not list their complete inventory online. To check if they have your part, e-mail them with a complete description of the part and the model. For example, try http://www.a1sewingmachine.com/parts.html .

I hope this helps.

Before the thread goes though the uptake lever, it goes though the tension (a round "knob" with numbers).

When threading the machine, lift the presser foot. This opens the tension control so the thread can enter and then when the foot is down and you begin to sew, the tension setting will determine how much thread should feed to the needle.

The setting is usually around 4. However, if this is an older machine that has been used a lot and serviced a little, the tension may not work as it should.

Try different settings and if you cannot get a proper stitch, you will need to determine if the machine should be serviced or if you should purchase a new one - service and parts can be 1/2 the price of a decent, new machine.

I'm guessing you would have loosened the tension? Is there grit or something sticky (dirty oil) stuck between the tension discs?

Please, tell me, is the main spintle, still on the machine, or it came off with the rest of the parts?

If you can put the tension parts, the one next to the other in front of the machine, and upload a photo for me, it will be very easy to explain how to put them back.

The thread will be threaded in a clockwise direction on the tension control. Pull the thread until there is a tension on the spring. There will be a catch on the thread that you will notice this. Now, thread the machine in the same way that is normal. It should work. Make sure you start your tension at four to test how it is doing. From there make slight changes in tension. Don't worry about the very tiny bend in the wire at the very end. It is only for weight and to keep your thread from catching and getting broken.
