Bought used and can't fix the problem. I have checked the needle bar height,the sewing hook position, and changed the needle. I have tried different thread and adjusted top and bottom tension. Any help will be appreciated. Thank you, Bob
Thread loops on the bottom is a sign that it isn't threaded correctly or the tension isn't set right.
Industrial machines tend to do some strange threading procedures. Are you sure you have it threaded correctly? Two of the machines I've had required that I do a 360 around one of the tension discs. I would start there.
Also some industrial sewing thread is waxed and that wax can cause you issues in between the tension discs. Raise the presser foot and take a piece of sturdy material like canvas or denim and "floss" between those discs. It will help remove wax build up that could be keeping your tension discs from working properly.
The machine is threaded right. I did have the tension to loose, but to get the stitch tight ,the thread starts to fray at the needle. I'm using T-90 thread and a Organ 110/18 needle. Thanks for your help, Bob
Fraying at the needle may mean that your needle thread combo isn't quite right. Here's a neat trick. Correct Thread - Needle Sizing Tip (1) Cut about 3 feet of thread that you are going to use (2) Select the needle that you are going to use (3) Thread the needle on one end and leave about 8 inches past the end of the needle (If the needle sticks at this point it is too small) (4) Hold the needle in one hand (thumb and forefinger) and wrap the excess thread around the forefinger (5) Take the opposite end of the thread in your other hand and drop it down so that it makes approximately a 45 degree angle (6) Make sure that the thread is tight between your two hands (7) Release the needle from your thumb and forefinger and watch the motion that occurs If the needle sticks at the top, it is too small - try the next largest needle. If the needle is jerky as it slides, it is too small - try the next largest needle. If the needles slides rapidly, it is too large - try the next smallest needle If the needle slides steadily & evenly, it is the correct size.

Hello, sewing is a part of my income and I've encountered this problem before and managed to fix it on my own, by trying out these different things. I re-threaded the machine and checked to make sure that the tension is not too loose. Check the bobin and the sack the bobin fits into, sometimes it comes loose too, click it back into place and re-do the bobin. adjust the tightness of the stiitches, I usually put it on 2 .5 - 3. Hope this helps. Good luck to all. [email protected]

Try a different bobbin. Look for one that is a little narrower. I had the same problem and changing to a narrower bobbin fixed it.

Did you bend the throat plate? I have done that and it was a nightmare. I took it off and gently hit it from the backside with a towel over it to bend it back the way it was. It worked fine.

Sounds like the hook/needle timing. To check do the following:
With the power off!!
remove bobbin and bobbin case.
push needle all the way to the left.
Turn handwheel toward you watching the needle and bobbin housing hook. The point of the hook should line up right above the eye of the needle.
If not timing, clean bobbin area removing lint and thread.
Check bobbin tension, should get slight resistance when pulling thread.
Make sure using only Husqvarna Viking bobbins -- most are green but they have new colors now. All will have the Husqvarna logo on them (an H). Make sure the bobbin is unwinding in the right direction.
Remove fabric. Pull extra long bobbin thread (about 3 inches). Hold upper thread tail in left hand, turn handwheel toward you for 1 revolution. Is the bobbin thread caught by the top thread and pulled through the opening of the needle plate?
If you are still unable to get a good stitch, take to an authorized Husqvarna Viking dealer for service or have them send to Husqvarna Viking (SVP) Technical Service Dept for repair. A list of dealers close to you can be found at the Husqvarna Viking website - http://www.husqvarnaviking.com/us
Good luck.

Make sure that there is tension on the thread when you have passed it through the tension unit, by making sure the presser foot is down, and then gently pulling the thread to feel tension. If there is no tension, as seems to be the case, check the tension discs inside the unit to make sure that there is no debris stopping them from closing.
