SOURCE: Singer 2010

If model 2010, the problem is a part metal- part plastic part attached to the bottom of the bobbin winding lever, the white tear-shaped thing with the arrow on it. If that will turn past the center of the bobbin it's broken inside. to try a do-it-yourself fix, turn upside down, remove 4 screws, including one by the plug (which must be pulled out for safety anyway) remove bottom case. looking at left end of the works, move the bobbin lever and you'll see the broken part move. The plastic part should be broken about half-way down. You can see how the part should push the white plastic bobbin winding shaft up and down when lever moved. the part can be removed by loosening the 2 tiny hexnuts holding it on the metal shaft. you'll need the smallest size allen (hex) wrench there is. NOTE where the part is at bottom of the metal shaft for when you put have to put it back on. be careful to hold the bobbin winding shaft itself in place, but it's easy to see how it goes back in if it pops out. if the break is clean (like my wife's that I just fixed this way yesterday!) you can put a drop or 2 of good crazy glue in the break, making sure lined up on the sides, then clamp in a vise (or hold firmly together with pliers) for at least 10 mins, longer better. wait at least an hour before putting back. putting back on is a little tricky but you move the bobbin lever to left (open) position, make sure it's just on the end of the shaft (shaft barely protruding) and see where the part isn't pushing the bobbin winding shaft. re-tighten with hex wrench then see if the repaired part now pushes the bobbin winding shaft up and down when you move the lever back and forth. Turn back over and move the lever without a bobbin spool- you should see shaft move up in the middle of bobbin case where it will engage the bottom of the bobbin spool where the x is.
Now if part can't be fixed it is available from auth Singer service center in you state but runs $40 or so. they'll try to tell you they have to install it because of special anti-static gloves that wont fry your motherboard on the machine's computer, but the center in Michigan finally said they would mail it to me. hope this helps! funny I just saw this after fixing our machine which hadn't been used for a long time until I decided I might as well look inside if I was going to have to buy her a new machine!!!

SOURCE: My problem is the stitch on the top is loose.

Lint or thread caught in the Bobbin Case spring......check all about tension here below. Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.

Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.

The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

SOURCE: jams

I make flannel square quilts for babies, it is a nightmare itself. It makes a lot of lint in the bobbin case and under the face plate, try prewashing the fabric before using it and clean out the bobbin case frequently while sewing. When i dont prewash it, i just open the bobbin area and blow the cotton dust out with my breath or i use the small brush to clean it out

Singer Model 5523 runs but doesn't make stitches. Needle is threaded and bobbin is fine. It moves but when I check the stitches there are none. Thread is not breaking.


I am not an expert on anything, least of all sewing machines...

The needle should carry the top thread under the table and make a loop that picks up the bottom thread from the shuttle and it is the interaction between the two threads with equal tension that creates the stitches.

The major activity of a sewing machine takes place under the table and in particular it is the timing of that activity in relation to the needle movements that is essential.
The timing is critical but mostly non-adjustable. I suggest you ensure below the table activity is actually taking place and then revisit the winding of the thread onto the shuttle reel and inserting it into the shuttle...

On my Singer 6235 sewing machine, needle will not pick up bobbin thread. Any suggestions to fix the problem?


Doesn't pick up bobbin thread
1. The bobbin may be in backwards.
2. The bobbin thread & top thread need to be pulled to the back before starting the stitching
3. You need a ballpoint rather than universal needle to sew on t-shirt knits.
4. the needle is in the machine backwards
5. Make sure the needle is the correct one for the fabric being sewed
6. Needle inserted wrong in the needle holder
7. Warped needle
8. Warped bobbin
9. Also could be a timing problem

Does any one know anything about a sewing machine model 217-APP no 457. Think it may be a singer, have just found it in late mother-in-laws shed. It won't pick up the bobbin thread but runs ok


not picking up the bobbin thread is an indication of needle / hook timing
thread tension problems appear as a mess of stitches under the cloth
the timing can be checked by having the needle full down and the hook of the bobbin case should be at the needle just above the eye of the needle
if it is too early or late then it is not in position to get the thread

Singer 9030 runs but don't sew


try changing the needle--make sure the needle is the correct one
for the fabric being sewed.
also make sure the needle is turned the correct way in the needle
holder and pushed all the way up into the needle holder.

Won't pick up bobbin thread


Refer to your manual to be sure the needle and bobbin are installed correctly.

If the needle is in wrong, the thread will not guide down the groove on the needle shaft and through the eye as it should in order to form stitches with the bobbin thread.

Picking up bobbin thread


First easy thing to check, are you using the correct length needle.
If this is not the problem then somehow the needle bar has moved and the the needle depth is to high or the timing is wrong..
Unless you really know what you are doing then I am afraid a sewing machine tech needs to reset the needle depth and subsequently the timing.

Skipping stiches


1) It’s possible the machine is threaded incorrectly. Remove the thread completely and rethread the machine. Be sure to use good quality thread--don't buy the cheapest you can find. A good thread will help your machine perform better and your projects last longer.

2) Poor stitch quality can be caused by the needle. Make sure you're using a new needle that's right for the job. Many times machines are taken in for repairs and all they need is a new needle. If you can't remember the last time you changed the needle--it's past time. Needles should be changed at least every eight hours of sewing.

3) When inserting a new needle, make sure the flat side of the needle faces away from the bobbin area. For example, if your machine has a frontloading bobbin, the flat side of the needle faces the back of the machine. If your machine has a side-loading bobbin, the flat side faces the right side of the machine. Some older sergers require special needles that don't have a flat side. Refer to your owner's manual to properly install a serger needle.


4) Thread that shreds or breaks can be blamed on the needle. Use a good thread and make sure the needle eye is large enough for the thread type. Also use the right type of needle for the fabric;
5) The machine tension adjustments put stress on the thread so it doesn't simply flow through the machine. When the upper and lower tensions are balanced, the stitch forms correctly. Tension is easy to adjust--stitch on fabric samples with a different thread colour for the upper and lower threads. Observe the stitch, adjusting the tension until the stitch is formed correctly. As a general rule, adjust the upper tension first. If the stitch still isn't right, adjust the bobbin tension.
