Fixing Bobbin Case in a Singer Sewing Machine

To fix a loose or fallen-out bobbin case in a Singer sewing machine, you will need to remove the screw that holds it in place. There is usually a small hole in the top or side of the sewing machine where you can insert a screwdriver to remove the screw.

Once removed, pull out the bobbin case carefully. You also may need to remove the bobbin case from a front-loading bobbin sewing machine.

On some machines, you will have to turn the tension dial toward “loose.” For most machines, you can simply pull out gently on the side of the bobbin case that says “pull” or is marked with an arrow. Once the bobbin case is out, screw it back in place.

After you put your bobbin case back into the sewing machine, turn the tension dial to “tight.” If you replaced an old or broken bobbin case with a new one, you may need to re-thread your machine by pulling out the lower threading plate and following the diagram of where to thread your machine.

If the new bobbin case was not threaded correctly, the bottom threading of your sewing machine will show on top of the fabric. If this happens, simply cut the knotting on top of the fabric and re-thread according to your sewing machine’s diagram, instructions manual, or tutorial.

How Do You Put the Bobbin Case Back in a Singer Sewing Machine?

  1. Line up the hole on the bobbin case with the corresponding peg on your sewing machine and slide it over to secure it in place.
  2. Take a small screwdriver or a ballpoint pen and push down on the locking lever while you also pull up gently on it until it snaps into place, holding your bobbin securely in place.
  1. Slide the bobbin case back to engage with the gear on your sewing machine, and then close up the casing to keep it there.
  2. To fill the bobbin, loosen the tension on your sewing machine by turning the small knob at the bottom of your needle rod, then pull out on its thread spool pin—this will expose the top of your bobbin case.
  3. Using a small funnel, pour some thread into the hole in the bobbin—the more you use, the longer your stitch will be and vice versa. You should use enough thread to go around smoothly three or four times, but not so much that it overflows out of the bottom. Back the thread spool pins back in to keep it secure.
  4. Once your bobbin is filled with enough thread, take your needle up and down (by pushing the top button) until you have about four inches of thread hanging out from its hole. Pull-on this thread gently so that it pulls itself through—this will slip the thread through the needle’s eye.
  5. While this thread is still pulled tight, push the spool pin back into place to keep it in line with your sewing machine. Loosen your top tension by turning that small knob at the bottom of your needle rod so you have enough slack for bobbin winding, and tighten your bobbin case’s tension by turning the knob just above where you put it it your bobbin in.
  6. Wind thread onto your bobbin by grabbing that hanging length of thread and gently pulling it while holding onto the top of the spool of thread with your other hand—the more you pull, the faster it will go so be careful not to let go of it.
  7. Once your bobbin is full, cut the thread to a short length and make sure that there’s no excess hanging out of it, or else it will get caught up in your machine.
  8. To test the stitch, bring down your lever on top of your machine—if you can see any gaps between where you’re stitching and the raw edge of your fabric, you need to adjust your bobbin tension by turning that knob above where your bobbin sits. If it’s not catching at all or if there’s too much thread showing between stitches, you can adjust your top tension by turning that small knob at the bottom of your needle rod.
  9. When you’re ready to start sewing, bring up the needle to its highest position and then lower your presser foot—you should be able to see a small hole where you can set your bobbin and make sure it’s lined up with your needle.
  10. Once you’ve inserted it into that little hole, bring down the presser foot and gently hold it in place so that you can sew a few stitches without the thread falling off. If it’s not going through, you might have to adjust your bobbin case a little—if it is going through but your stitch isn’t catching on the other side then decreasing your top tension will help.
  11. Keep sewing until you’ve finished using the thread on your bobbin and then take it out of the machine—this will be easiest if you can reach down to grab it with your hand or if you have a little tray for bobbins that attaches onto your machine (make sure that’s not in the way first!)
  12. Take the top off of your bobbin case, pull out your bobbin, and then simply put in a new one.
