When backstitching the needle comes down and goes through the thread and tears the thread apart

SOURCE: Thread breaking.

Rethread the machine following these directions:
all machines thread the same. TTN tension, take up, needle.
Beginning with the spool, guide the thread through the thread guides to the tension assembly. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle. Make sure your needle is fully inserted and turned the correct way.( If you load your bobbin case from the left side,the needle rule is normally FLAT to the RIGHT is RIGHT. There are some exceptions. If you have a newer style drop in bobbin or your bobbin case loads in the front then the rule is FLAT to the BACK.
Remove the bobbin case and bobbin. Pull on the bobbin thread to make sure it doesn't pull too hard. It should have some tension on it but not a lot. Insert the bobbin and bobbin case into the hook assembly and pull on the bobbin thread again.The tension should still be about the same. If it is tight, you need to look at the bottom of the pin that the bobbin case sits on and see if there are any threads looped around it. If there are , you need to remove them.
Hold the top thread , turn the hand wheel and see if the thread is catching someplace around the hook assembly. If it pulls the thread up easily, put some fabric in it and see how it works.
Make sure the thread is through the take up lever.

Found the problem (s) with Viking stuck on backstitch!!!

Two problems:

A: machine is "gummed-up" form old grease.
Solution: degrease machine with a high quality degreaser.. I used a spray electrical degreaser from an automotive store. Turn the machine up-side-down to preform this!
Then relubricate machine. Use a high quality sweing machine lubricant! Also lubricate the inner parts with a qigh quality "Sewing machine" oil.

B: Found that the return spring from foreward to backward was tired.
Soultion: Replace with slightly stronger spring from local hardware store.

If you need pictures, I took very detailed pictures of the reverse mechanism and "return to forward" spring.

SOURCE: Thread in needle or bobbin keeps on breaking

The tread only breaks in the needle. what can i do . i don't get to sew anything . I tread the needle and get everything ready and start the machine and as quickly as that the tread is broken and the machine has not sewn at all.

I answered this a couple days ago but don't know if it went through. I can sew through 6 or more layers of denim with my 226, no problems at all. In my 30 years in the upholstery business I never had a problem sewing leather, vinyl, canvas or multi-layers of fabric. The 226 Consew, the 111W and 211w Singers I had presented zero problems with heavy fabrics - and I don't consider vinyl "heavy".

You need to first of all check threading. If the machine's threaded wrong you're break thread. Also you need to oil under the bobbin case and the bobbin hook and the rest of the parts as well.
Then, loosen thread tension on top by turning the knurled knob that's on the spring that's holding the tension discs. Also loosen bottom tension on the bobbin case by turning the small, left-most screw on the outside of the bobbin case counter-clockwise. Do both with the presser foot down. Pull the thread(s) out and feel the tension. You should be able to pull the threads out with some little effort. Tighten both a little at a time until you get some tension. Run a couple seams and check where the threads meet in the fabric. They should meet in the center. Also check stitch length. If you're using 92 thread (is should be left twist), you should run the machine at about 6 - 7 stitches/inch. I'm running my machine at 5 - 5 1/2 with #69 nylon bonded, and 6 - 6 1/2 with #11 mono.
One more thing; if tension's too loose at the bobbin or top, the machine will jam in the bobbin and thread will break.

I had a similar problem and then realized that the thread on the top had a **** on the spool it was catching on.
