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

Did you happen to reload your bobbin and then it started shortly there after? Maybe try a different fabric, thread, and bobbin, just to test the machine.

It's probably out of time, or a belt inside has slipped. If it's computerized..could be a card burnt out. Wish I could help more, but I don't have this machine.

I know this was ages ago but now I am in the same boat :/ did you happen to find an English manual for this machine??

Bobbins are specific to machines.........if you are trying to use a non-singer bobbin, the diametre and depth may well be several millimetres different and will result in what you describe.

Ask for plastic singer bobbins for a top loader......if you contact Singer or an agent, they will give you a part number and will probably ship to you as well.........get a few and have all your colours ready, not all layered on just a couple !

When you thread and then start up your machine to sew, for instance, a seam, there's one more step you have to take. After you have threaded, placed your fabric under the foot, and put your presser foot down, pull a length of thread--enough so you can grab, maybe 3" or 4"--pull the thread to the back of the machine and then hold it down for the first stitch or two. You see, when it starts to take the first stitch the upper thread pulls towards the machine, and if there's not enough left over, it will pull it right back though the needle! All you have to do to get around that is to make sure the end of the upper thread is being held down with your hand long enough to take the first stitch or two--then you can let it go.

Easy to do remove sole plate remove shuttle and case, don't forget to pull the spring loaded plate to one side by inserting a electrical screw driver in the slot and twisting it anticlockwise to release the case, remove drive dogs this will the expose the cotton pickup assembly turn the hand wheel anticlockwise until the hook gets close to the needle now watch the needle it should be in the lowest position and just as it starts it's way back up the hook should be just going behind the needle to pick up the tread if this is not the case and it's out of position then hold the hand wheel tight and insert a small screw driver into one of the gaps in the base were the shuttle case fits in away that you are able to move the hook assembly one way or the other with a gentle pressure and move the hook just to make it enter just behind the needle as it only just starts it's way up at this position it is now complete and you can reassemble and run slowly at first just to make sure things are okay. Happy Sewing

Very likely there is a thread or two stuck in the bobbin area. Open up the bobbin door, remove bobbin and bobbin case. Now try to turn it with the handwheel. If still no action, then look closely at the socket where the bobbin case fit into. There are 2 black plastic levers -one on each side. Move each one outward. This will allow the center to easily fall out. Now move the hand wheel. If it is still stuck, then remove the needle plate. Remove two screws to allow the plate to come off. Now you have a clear view of all the mechanism around the needle and bobbin area. Remove stray dusty bunnies, thread etc. If that does not do it, then you may have an issue with the belt or motor -but not too likely. Reply if you are still having problems. Moses

I went to the Singer site and downloaded (free) and took a look at your user's manual, and page 11 has it pictured, with instructions. I don't believe that it tells you this, but when the lever is out the bobbin won't come out. I would recommend that you download the manual as well; it can be very helpful.

Could be needle is damaged or inserted wrongly. Check manual for proper insertion orientation.

Download the user's manual from the Singer Sewing Machine site. It is a free download (I just checked, and your model is there), and it will show you with pictures how to do that.

ALL sewing machines have two disks that face each other in the thread path that exert tension on the top thread, and when threading you must get the thread between those disks to get any tension on the top. However, on ALL sewing machines, going back to their creation in 1859 (that I know of), you MUST thread your machine with the presser foot UP, because that is the only time the disks are spread to ACCEPT the thread. You have probably been threading your machine with the foot down. Another must as a side note--you MUST turn the hand wheel TOWARDS you at ALL times. If you turn it away from you more than one revolution, you risk throwing off the hook timing.

maybe check the threading of the machine

Reduce tension. Perhaps it is very thin - or cheap thread? Or very old thread? If so, replace with good thread. If that is OK, them try to lessen the tension. Moses

Some spool pins are screwed in and some are just wedged in. You can purchase a wedge in spool pin from your local store and use it to replace a screw in one but you cannot use a screw in pin to replace a wedge in type.

Hello

Set the tension on the sewing machine for the weight of the material you want to sew. The tension setting shows in the stitch on the material. Use the chart on the machine that matches types of stitches with suggested material tensions. An example of this is, the stitch to sew jean material is different than the stitch to sew silk.

Take the bobbin and wind the thread around it. Make sure the bobbin is empty and don't fill it too full of thread. A bobbin filled too full won't stay tightly spun.

Thread the string evenly on the bobbin. Move the thread back and forth evenly and in layers that are level. Many Singer sewing machines have a bobbin winder on the top of the sewing machine, and the consistency of how it threads can save you frustration later.

Find the hole on the bobbin that is located near the inside spindle of the bobbin. Take the thread sitting on the sewing machines spool and insert the thread in the hole from inside the bobbin to the outside. Set the threaded bobbin on the spool designated for spinning on the top of the sewing machine for some Singers.

Turn the side drive wheel slowly until the threaded bobbin has a layer or two of thread on it. Push down on the drive peddle and fill the bobbin, but don't thread it to the very edge. If the bobbin is too full the thread will release erratically. Cut the thread from the spool.

Drop the bobbin into the bobbin case under the area where the needle sews the material. Close the case and turn by hand the side wheel drive until the bobbin threads into the sewing machine. You can tell when the bobbin is threaded by the tiny piece of thread that juts out of the bobbin case where the needle goes up and down.

Grab the thread with your fingers and pull it out approximately 4 inches. Your bobbin is now spun and threaded.

It sounds like your machine is set to wind the bobbin right now, so the drive is disengaged. That would explain why the bobbin winder pin is the only part moving. Check your manual for how to reset the machine when you are finished winding the bobbin.

Most machines have a way to disengage the drive for the needle while filling the bobbin. Then once the bobbin is filled, you re-engage the drive. Some machines have a separate, smaller hand-wheel that turns and clicks into place. Some machines automatically reengage the drive once the bobbin pin snaps into place away from the drive belt.

I hope this helps!
