Bobbin timing Winding a bobbin seems to have jolted the hook out of time. I adjusted the timing following the man. instructions, now the thread breaks and the stitches are uneven in places, perhaps I don't have the timing just right, any suggestions?

    My problem started while rewinding a bobbin. The machine jammed, slipped the top gears and got everything out of time. I readjusted the gears so that it will run, but is noisy. Had the timing reset then on the next bobbin refill, it would not sew. Keeps breaking the thread near the bobbin. Seems they should have designed the machine so that it does not run while filling the bobbin, like the old home machines. I have had this happen more than once.

Don't ever pay to repair a sewing machine when timing, oiling, living, tension problem/s, problems with bobbin/ thread breakage, cleaning race shuttle, oiling hook, etc are just a matter of reading and doing yourself! I have been fixing sewing machines for 30 yrs. All you need is patience and carrying out each step.

My Kenmore 158/900 is not looping the bottom stitch from the bobbin thread and the thread sometimes breaks

Can be several causes. In typical probable order for rotary hook machines;
1.Top thread tension is too high (lower tension)
2.Top thread snagging at spool or elsewhere (for hoizontal spool use larger spool cap and/or machine not threaded per specific instructions)
3.Bent needle or barbed needle point (replace needle)
4.Needle not properly inserted into holder (see specific machine instructions)
5.Debris in shuttle hook/race (clean bobbin, hook, race)
6.Wrong bobbin (replace with proper machine bobbin)
7.Bobbin thread tension too high (reduce bobbin spring pressure, likewise top thread tension)
8.Poor quality or extremely light thread (if using cotton only thread, test sew with a polyester blend and see if problem goes away)
9.Bobbin case (replace bobbin case)
10.Machine timing. (check/adjust timing)
11.Burr in hook race, this can happen if a broken needle point jams in the race (remove burr or replace race)
12.Machine timing. (adjust timing)
13.Hook is worn or damaged (typically not a worn hook unless a few hundred hours of use, look for a barbed or bent hook point) Watch following Singer video... see testing top thread tension.

I am not sure about this particular machine but in most machines there will be a nob on the front loose low numbers like 0 1 -2 work well on number 3. If the nob is not on the front check and see if it is on the side.

Needle hitting this and breaking. Pulling too ******* thread caught in bobbin case is the cause. How to fix or readjust?

breaking needles from hitting can be from several problems
1-- needle /hook timing is out
2--needle thread tension is too tight pulling needle side ways
thread caught around bobbin holder is top thread too loose
take it in for a service check as the needle /hook timing is complicated to adjust and the problem could be more complicated than suggested

My needle thread keeps breaking. I've tried different thread (top and bobbin), a new needle, and I opened up the bottom plate to clean out lint. I have also tried adjusting the thread tension.

Are you sure you have got the top thread threaded correctly including the take up lever? Start at the thread spool and follow the thread all the way through the thread path checking that it is not snagging on anything enroute and that the thread is correctly through the tension device. Also tension dial should be on 4-5, if its higher this could be breaking the thread. YOu should not need to adjust top thread tension more than a half increment at any time.

Other possibility is that the bobbin holder under the needle plate has moved out of alignment and then the top thread is catching there as it goes around the hook.

If you check your manual it should give you instructions on removing the needle plate (2 screws need to come out), then you can lift the bobbin case out towards you, clean underneath with your little brush, then reinsert it. There are two little red marks on the right side of the bobbin case and a stopper, these need to be lined up. Then put in bobbin and rethread into tension spring, replace needle plate, bobbin cover, and test stitch.

Hopefully one of the above is causing the thread to break.

The main thread is not catching the bobbin thread

It looks like your timing of your bobbin hook is out you will need to have a service man adjust it for you.

I have a Singer mod 9134 sewing machine. It keeps

Try inserting the bobbin in the reverse direction. Most machines take a bobbin clockwise or counterclockwise and it can make a difference. Also try a new needle, a bad needle is often the problem believe it or not.

Bobbin won't thread

I just bought my White sewing machine used and the model #967.I had problem winding a bobbin so my husband helped me. what I had to do was hold the arm with the bobbin on up agains the wheel. I know it seems to be a pain but this machine has all kind of attachments.

Thread breaks off

Where does it break? You change tension at the top via the tension discs the thread passed through, and at the bottom by adjusting the small screw on the bobbin case - the screw on the front part of the spring. Thread size matters as well as needle size. For everyday upholstery I use #69 nylon thread, and "G" bobbins.
If the thread's breaking at the hook you may need to adjust timing. But most commonly thread breaks because of improper tension, threading, needle or thread size.
