Question about Juki DDL-8700

Bobbin house is not lined up with the needle for a full turn. How can I fix this?

I had a needle slip out of the shaft when I was winding a bobbin, the wheel stopped and needle was jammed between the throat plate and the bobbin housing. I broke the needle to remove it all pieces are clear of the bobbin casing. I examined for damage and didn't see any. the hand wheel was turning so I put in a new needle and tried to turn it but the bobbin house is not lined up with the needle for a full turn. The manual doesn't address this .please help

Your machine is out of time. This means that your bobbin casing is not rotating at the right time to be able to grab the thread from your needle. You should take it to the mechanic to have it fixed.

SOURCE: tangle in bobbin area, stuck needle

Please TRY the solution BEFORE giving your considered rating.




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 !

It's actually designed that way on purpose so you can wind a bobbin while sewing. If you lift the presser foot, at least it'll make less noise in the process.

SOURCE: needle won't pick up bobbin thread tried cleaning

Hi,
did you clean the bottom bobbin area thoroughly? Remove the cover plate and bobbin reel, look for debris. Any left over cotton will cause problems, after you clean it spray some wd-40 on all moving parts.
Thanks
Adam

Be sure you have the proper needle - it is longer than standard needles, plus be sure that you put the needle in from left to right - not...front to back.

Code 88 starts flashing as well as all the stitching lights on the panel when I try to thread the bobbin. I can sew, that is NOT the problem, threading the bobbin is. What is Code 88? I am not interested...


Turn your machine off and leave it off. Remove all bobbins - in the machine & from the pin. Remove all thread - from threaded machine and bobbin thread path. Clip the machine thread at the spool and pull the needle thread towards yourself. Clip bobbin thread at spool and close to bobbin, then pull towards you through thread guides. This keeps the tension where it belongs. Move the bobbin winding shaft from normal sewing back to winding bobbin a couple times. It should click in place when moved to the winding position. Check to see if there is any thread that has slipped under the bottom of the bobbin and wound itself around & under the bottom of the shaft. Carefully unwind to clear. If the shaft does not easily move back to the sewing position it is probably stuck in the winding position. Don't force it, but try to get it out of the winding position. Leave it to the left in the normal sewing position (unclicked). Check to see if there is any thread caught anywhere along the path from spool to the winding pin. Pay close attention to the first thread guide and the two discs the thread slips between that control tension. Hand wind the wheel on the right towards you to raise and lower the needle a couple of times. Stop with needle in highest position. Do NOT wind hand wheel backwards (away from you). Make sure the bobbin pin is not in the winding position. Now turn on your machine. Needle should jump to default position. Move the stitch length and stitch width guides to the far right, then far left, to attain the green lights. Press the reverse stitch button to raise lower and raise the needle. It will stop in the highest position. If you still have the error code - make sure the bobbin winding pin is NOT in the winding position. Remove the needle. Lower the presser foot and run the machine without any thread a bit. If the needle bar does not go up and down most likely the bobbin pin is stuck in the winding position. If the code has cleared use your manual to carefully wind a new bobbin. Make sure you are using a 15J bobbin which this machine requires. It will not work with just any bobbin. Next, raise the presser foot then carefully thread the machine. If you don't have a manual you can download one from the Singer website. You might consider cleaning the entire machine paying special attention to the hook area and feed dogs while the power is off. If you find a lot of lint do this more frequently to prevent buildup. Take special care when replacing the bobbin care. Hope this helps. If not call Singer. It may take some time but you should be able to reach someone to help you troubleshoot. If this is an older machine I recommend taking it for repair yourself instead of sending to Singer

How to fill a bobbin on Virtuosa 150


Put the thread spool on the vertical spool holder with a sponge pad underneath. Wind the thread off the spool and through the small wire thread guide next to the spool holder. Take the thread across the top of the sewing arm to the tension unit just next to the gap in the case through which the thread is normally threaded - the tension unit looks like the top of a shiny screw without the slots in it. Wind the thread in a clockwise direction around the tension unit once and pull the thread with a bit of tension until it slips into the sprung gap around the underside of the shiny part. Slip the end of the thread through one of the holes in the bobbin and, preferably, wind a few turns on, then push the bobbin onto the bobbin winder shaft at the right-hand end of the top of the machine. Turn the bobbin clockwise by hand a few more times to make sure the thread is 'locked' onto the bobbin and then just push the lever adjacent to the bobbin winder to the left. To wind the bobbin, you then press the foot controller and either stop when you've got enough thread on the bobbin or let it stop automatically when full. Make sure you dont go so fast that the spool rattles-around on the spool holder otherwise this could spoil the way the bobbin gets filled.

How to fix new home machine it model No.731016401. model 360 manufactured by Janome its not sewing cloths. The thread is placed properly but when i try sewing it starts to break the thread. it turns in...


Upper thread breaks
1.needle may be in backwards
Correct needle insertion
Correct needle insertion is mandatory for proper use of sewing machine.
Raise the needle bar to the highest point, then loosen the clamp screw to remove the old needle, place the new needle in the clamp with the flat side to the back of the machine or if using a round needle--the groove in the needle should face away from the shaft.
Push the needle all the way up to the stop or as far as it will go, then tighten the needle clamp screw
2.upper tension may be to tight--try 3 to 5
3.the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
4.thread may be hanging up in bobbin case--check area for loose threads or lint
???
Lower thread breaks
The most probable cause of lower thread breaking is improperly wound bobbin
1.always start with a empty bobbin
Never wind one color over the other
2.choose thread that is identical in color & type as the one to be used for upper threading
3.wind the bobbin evenly across & in layers
4.don't wind the bobbin so full that it would be tight & hard to insert into bobbin case
5.bent bobbin--replace
6.lint built up in the bobbin case--frequent cleanings will eliminate this problem, the more often you use the sewing machine the more often it needs to be cleaned
7.thread catching on the bobbin spring or latch on bobbin case, check to see that the bobbin is inserted completely & correctly, & that you are using the right kind of bobbin

also check the thread take up lever to make sure the thread has not come off of it cause that can make the machine jam up also

I need to know how to thread a bobbin?


TRY THIS, itma not be your model, but should help Title:
How do I wind the bobbin? windingbobbin_02.jpg
ac093.jpg Pre-tension disk ac094.jpg Bobbin winder shaft ac095.jpg Bobbin

1. Pull up the spool pin as far as possible, and then put a spool of thread on this pin. windingbobbin_a0991.jpg
2. Pass the thread around the pre-tension disk. Make sure that the thread passes under the pre- tension disk.
windingbobbin_a0992.jpg ac098.jpg Pre-tension disk c_b4.jpg Pulling it in as far as possible

Caution If the spool of thread is not in the right place, the thread may tangle on the spool pin.

3. Pass the end of the thread through the hole on the bobbin from the inside of the bobbin. windingbobbin_a0993.jpg
4. Put the bobbin onto the bobbin winder shaft and slide the bobbin winder shaft to the right. windingbobbin_a0994.jpg
5. Turn the bobbin clockwise, by hand, until the spring on the shaft slides into the groove of the bobbin. windingbobbin_a0995.jpg ac099.jpg Spring on the shaft ac0991.jpg Groove of the bobbin

6. Turn on the sewing machine. windingbobbin_a0996.jpg
7. While holding the end of the thread, gently press the foot controller or press start/ stop button (for models equipped with the start/stop button) to wind the thread around the bobbin a few times. Then stop the machine. windingbobbin_a0997.jpg
Note
  • If the sewing machine is to be operated using the foot controller, connect the foot controller before turning on the machine.
  • When the foot controller is plugged in, the start/stop button cannot be used to start sewing (only for models equipped with the start/stop button).

8. Trim the excess thread above the bobbin. windingbobbin_a0998.jpg
Caution Make sure you follow the instructions carefully.
If you do not cut the thread completely, and the bobbin is wound, when the thread runs low it may tangle around the bobbin and cause the needle to break.

9. Slide the sewing speed controller to the right (to set the speed to fast).
(For models equipped with the sewing speed controller.) windingbobbin_a0999.jpg ac0992.jpg Sewing speed controller
10. Press the foot controller or press start/stop button (for models equipped with the start/stop button) to start. windingbobbin_a18.jpg
11. When the bobbin seems full and begins spinning slowly, take your foot off the foot controller or press start/stop button (for models equipped with the start/stop button). windingbobbin_a19.jpg
12. Cut the thread, slide the bobbin winder shaft to the left and remove the bobbin. windingbobbin_a191.jpg
13. Slide the sewing speed controller back to its original position (for models equipped with the sewing speed controller). windingbobbin_a192.jpg


Caution Not winding the bobbin properly may cause the thread tension to loosen, and may break the needle.
woundbobbin3.jpg ac0993.jpg Wound evenly ac0994.jpg Wound poorly


Note
  • When the sewing machine is started or the handwheel is turned after winding the thread around the bobbin, the machine will make a clicking sound; this is not a malfunction.
  • The needle bar does not move when you slide the bobbin winding shaft to the right.

Elna 6003Q Sewing Machine won't snap out of bobbin winding mode


I had the same problem and fixed it myself. Remove the portion of the housing that coincides with the bobbin winder. You will need to remove two screws to do this--one is just to the upper left of the bobbin winder itself, and one is hidden under the handle on the left side of the machine (lift the handle, and look on the machine on the left side.) It takes some coaxing to remove the housing, but it can be done--be gentle. If you need to, remove the housing on the left side of the machine that covers the needle assembly. This will make it a bit easier, but still, be gentle.)
After removing the housing, you will see a black metal piece with a elongated slot and a screw adjacent to the bobbin winder mechanism. Unscrew the screw a turn or two, and slide the piece to the other side. Tighten gently. Turn your machine on, and move your bobbin winder back and forth and watch the screen change from bobbin winding to the main straight stitch screen. Now, do a brief Dance of Joy. I hope this helps.

Singer 6267 self winding bobbin winds around shaft under


I just figured out why my bobbine was winding on shaft instead of on the bobbin. first of all make sure the bobbin is setting up high enough, top of bobbin needs to be a fraction higher then the bobbin shuttle, next check to make sure there are no burrs on the bobbin, then make sure that the thear is catching in the groove (**** in top) of the bobbin. In order to get mine to wind i had to lett the tread go down and then slip the thread in the groove. also remember to leave the pressure foot up do not put it down. let me know if this helps.

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!!!
