Bobbin case I can't express to you the level of frustration I feel with this machine. I have had it for three years and it is a piece of cr.ap! My biggest problem is that the bobbin case will NOT stay seated. It continues to pop out, often so violently that it throws the timing of the machine off and I have to have it services. Singer has not offered any solution as to why this keeps happening. Maybe someone else has a suggestion?

Would suggest simply purchasing a new bobbin case. Trying to reinstall a spring that is probably distorted will cost you more in time and frustration than the price of a new one. Plus the new bobbin case will have the tension preset from the factory. Pop it in your machine and sew...

Hai, First you should learn and try to your old machine how to operate the machine? After you started to operate a new machine. Then first you check the timing and change the bobbin case and needle.

You may have a timing problem or bent needle. You will need to replace the bobbin basket if it is damaged.

Is the Bobbin the right size for the machine? That may keep the bobbin case from latching properly, causing this phenomenon. Shuttle latched in properly? Machine cleaned and oiled per the manual? Make sure bobbin is wound straight and correctly... Post with results or follow up questions

Yes it can be frustrating, I believe that you have a tension prolem with the bobbin case.
The upper tensions should be 3 to 5 normally on your machine.

When you pull the bobbin thread do you feel any resistance? If not then you may need to check that you are threading the bobbin into the case correctly, re test


if that doesn't work then look for a little screw, turn it clock wise to create some light tension on the bobbin thread. Re test

If that fails take to local tech for repairs.

Best of luck chris

looking straight on at the area where assembly goes, First clean and oil area, the jam was likely caused by accumulated dust or a small piece of thread . You should have three pieces, four including the bobbin itself. first piece to be replaced has a center post this piece goes into the machine by fitting it to the bobbin area, it will only go in one way so when it fits into place you will know. the next piece is a ring this piece has a small piece of metal attached to the top when looking at it correctly the two screws will be on top and there should be two indentions. first one is at 3 oclock and the other is at 9 oclock fit this piece into machine and there should be a lever on either side that turns around and rests in to indentions. replace your bobbin in the bobbin case ,be sure to thread the case correctly and load into newly assembled bobbin area making sure that it clicks into pplace

Rule of thumb.. Loops on the bottom, problem on the top. Loops on the top, problems on the bottom.

Set your upper tension at 4, and rethread the machine from the top. Just before you thread the needle, but the presser foot down. If the thread pulls right thru easily, then the thread is not thru the tension wheel right. Because, if you can't pull the thread thru with the presser foot down, you have it threaded right.

youch!  how frustrating.  It sounds like there is a piece of thread caught in or around the bobbin casing.  take the whole casing out and clean with your brush.
I feel your pain, hope this helps.  If not, please come back and we'll try some other things.

frustrating huh?  it happens!  even to us that have been sewing for 50+ years, but the solution is very simple.  Top thread tension is the culprit.  pull the spool all the way off and rethread the top, follow the threading path precisely and make sure the thread goes down into the tension discs.
one more thing - when that happens often times the piece has to be removed from the machine by cutting those annoying loops on the bottom.  if this is the case, make sure you have removed all the thread clippings from in and around the bobbin case.  sometimes one little piece of thread will make you want to use swear words.
good luck and happy stitching.

I was having the same problem with my machine and finally the spring broke. I couldn't find any parts for this so my husband made me a new spring out of a coke can! LOL!! Anyway, he messed with it for a while and it kept doing it. He figured out that it was not the spring but the other piece under the spring was not pushed up far enough to keep the bobbin case in place so he took a screw driver and pushed it forward toward the bobbin case and now my bobbin case does not move!! And the machine is sewing perfect! At least for now. Anyway, it's not the spring or the thread adjusting screw!
