SOURCE: janome 9500 bobbin tension too tight can I adjust it

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: Bobbin issues

Take out your bobbin case... there should be a small screw fixture on the side of the case...turn screw anti clockwise until you get the correct tension ... To test the bobbin thread tension...Remove the bobbin case keeping bobbin attached and hold it by suspending it by the thread...**** it once or twice, if the tension is correct the thread will unwind by about an inch or two. If it does not unwind at all...tension is too tight. If the tension is too loose it will drop too much. Goog Luck

SOURCE: The bobbin tension too tight on my Singer Quantum 9240.

I am having this problem also; the thread catches in the **** in the bobbin. I am thinking maybe I am not threading the machine correctly--the bobbin area, not the top thread. I will try this & see if it fixes the problem. You may be doing the same as I am.

I have a Quantum CXL Singer sewing machine and the thread keeps breaking. It will make about 3 stitches and breaks. It is breaking in the same place.


Make sure the thread coming off the spool is not wrapping around the spool spindle. Install a brand new needle. Remove ALL the thread from the machine. Clean bobbin area of any dust, lint, threads. Set upper tension to the midpoint. RAISE the presser foot and then totally re-thread the machine from beginning to end verifying the sequence is correct. Test.

I have recently bought Singer Quantum 9940 and I am not happy with the stitch. For zigzag stitch, I can see too much of the upper thread on the bottom side. This happens unequally: more on the right hand...


1. Make sure your needle is correct for the fabric. Go buy some good needles in several sizes. You'll need a 90 for jeans, rounded points for fine fabrics... get a few sizes. Your manual should provided you with clues to the right needle for the fabrics. (BTW... there really is no such thing as a Universal Needle... toss it.)

2. Re-read your manual and carefully follow the instructions on threading the bobbin and the upper thread...

3. Check your tension on the upper thread... it is too loose for the application. The tension on the bottom thread is handled by a spring on your bobbin case or race. If you do not have that threaded properly you'll have problems. Same with the direction the bobbin turns... have in it backwards... problems.

Barring all these things... It might be time for a qualified Singer repair person to look at it. Sadly Singer has seriously lowered it's standards in the last 20 years.

MY THREAD KEEP BRAKING


it could be several things
check the needle to see if bent-roll on flat surface to see if it roll correctly
if the needle makes a popping sound when it penetrates the fabric is blunt
check to make sure the needle is not in backwards
check upper tension it may be to tight
thread may be hanging up in bobbin area-clean bobbin case area for lint or loose threads
check to make sure the thread is not caught somewhere
try using different thread

The bobbin tension too tight on my Singer Quantum 9240. I believe there is a tension adjustment I can make on the bobbin case, but I have not been able to find my manual since we moved 2 months ago.

Quantum CXL The needle will not pick up bobbin thread. seems to hit medal. It is not a 1000 model It was bought 11-01-95.


Your shuttle timing is out, this will need a qualified mechanic to fix it, it is to complicated to explain, as the needle timing may also be out.l

Loopy thread during stitching


if loops appear on underside of fabric, make sure machine is threaded correctly (check instruction manual for threading). when presser foot is resting on feed dogs, needle thread should be quite tight when pulled through needle (needle should bend a little). if thread does not feel tight, check threading again and ensure thread is between tension discs (presser foot should be up for threading and then down to check tension). if threading is good and tension seting is at 5 but still not tight enough check no htread is caught in tension assembly. if tension assembly is clear try tightening needle thread tension to 6,7 or 8 and see if that helps.

if the above is correct check for damage to the needle hole in the needle plate and polish with fine emery tape if necessary.

if you still have trouble best see a technician for possible repair to bobbin case or hook/shuttle mechanism which you may damage trying to fix yourself.

Tension not correct


Just set the tension on the bobbin casing but very little at a time, to much and you will never get it wright again. Then also try the tension at the top after adjusting the bobbin casings tension.
