Needle is hitting the round , turning case that revolves around the bobbin

I have been sewing a lot of cloth diapers lately. All of a sudden, my needle and the round, turning metal piece that encircles the bobbin seems to be off. There is an open space that the needle seems to sink into normally as the metal piece rotates. Now, with each rotation the needle goes down and hits the metal, rather than sinking into the hole during the rotation. Does this make sense? It ends up bending the tip of the needle and jamming up the machine. Seems like the little rotating metal part is not synchronized with the needle anymore. I am sure I am not using the right terminology. I hope you understand what I am referring to. Thanks for your help!

    This certainly not only your machine - it seems everyone with this machine has the same problem.  I took it to the professionals and they say that Euro Pro is junk and they cannot help me with it. So I am stuck with this **** machine that does not work.  The bobbin holder keeps jumping out and jamming the thread.  I am totally disgusted because Euro Pro won't even answer their calls or emails. Real nice customer service. I feel I have been sold a LEMON!!

Try installing a brand new needle. A bent/damaged needle will sometimes deflect and hit in the bobbin area. In the future, try replacing with a new needle every 8 hours of sewing time.

If the new needle does not work, then the needle/hook timing is off (probably because the needle hit a hard substance and knocked it off). You can search online for web sites & videos re repairing sewing machine timing. Otherwise, you need to take it for service.

It sounds like your timing is off because what you're describing is exactly what happened to me last summer. I took it to a sewing machine repair shop and they repaired the problems, gave it a nice cleaning and it was like new when it came home. But it took two weeks (not a lot of repair shops around here) and that was torture as it's my only machine!!! :)

I have an old touch and sew and went online to find out how to fix the timing myself. It took a little time and patience, but I did it myself. Saved $135 from going to the repair shop.

How do i disconect the drive to wind a bobbin

To "disconnect" means the sewing needle and feed dog is not functional if I understand your issue.
1. Disconnect: On the hand wheel there is a small outside ring in the center. Loosen it by turning towards yourself.
2. Take the thread from the sewing spool to the front gadget (round tension) and run around it in a figure eight appearance and run it to the bobbin.
3. Place the thread to enter the bobbin in the center with part going upwards into one of the holes to temporarily hold the thread until the bobbin is revolving. The bobbin must be pushed to the right to get the bobbin revolving.

Bernina 1080 Solution for "back spin"? Top thread suddenly becomes very loose. Top thread forms loops under cloth being sewn.

Try these suggestions
1. Change the needle--use a needle that's for the fabric being sewed
2. Rethread the machine--top --make sure to use every thread guide
3. try a different bobbin--make sure bobbin is inserted correctly into the bobbin case
& make sure the bobbin is turned the correct way in the bobbin case
4. make sure the thread has not come off the thread take up lever
5. Clean under the needle plate & in the bobbin area for lint or threads
6. Check to make sure the bobbin is not warped or damaged
7. Make sure the bobbin case is correctly in the machine,, if it's a top loading bobbin you may need to have the bobbin case checked to see if it's damaged or see if the hook and hook race has a problem
8. Make sure the top thread tension is on the correct setting for the fabric being sewed.
9.Also could be a timing problem, and the machine would need to be checked.

Noisy bobbin

If you bought new bobbins, they might not be quite round. This happens on mmetal bobbins.Another thing that happens is that you may have broken a needle and bent your bobbin case enough that the bobbin hits it as the shuttle goes around. If neither of these is the case, you might try to put a drdrop of oil in the "race" , which is the small grove in the piece that revolves around the bobbin case as you sew.

My MC9000 is jamming when I go to sew (normal sewing/default sett

You may have to replace the bobbin race. It is the round compartment (Black) that the bobbin sits in. If the needle has hit the race because of misthreading, it may have displaced it and put a hole in the race. Not very expensive to fix... want to say somewhere around $30

Good morning,

A question to help determine what's happening with your machine(s).

Open the bobbin case so you can see the bobbin area. Begin by trying to turn the handwheel towards you and watch as the needle attempts to go up/down. If you cannot turn the handwheel towards you, turn it slightly backwards then forwards. Does the needle hit the bobbin case as it comes down?

If yes, your machine is out of time and will require a professional technician to repair.

If the above is not the case, there may be thread jammed behind the bobbin case or wrapped around the inner parts of the take-up lever.

Either case - a Pfaff authorized technician would be your best bet for a proper repair.

Best of luck with your machines - it's just awful to not have the at the ready for all our projects!

Happy sewing,
Kim & Linnette

Black bobbin case

If this is the machine I think it is the bobbin case is completely round as opposed to half round. If it is half round ignore the following.
Remove the presser foot and then the two screws which hold the needle plate. Lift off the needle plate and then lift out the old bobbin case. Clean all the lint out and then insert the bobbin case so that the less round part of it is to the back and the lip around the bobbin case is resting on the lip around the hook. Turn the hand wheel a few times to be sure it is working smoothly and not binding. Replace the Needle plate , bobbin and presser foot. Insert a new needle,thread the machine, Check your tension to be sure it is working correctly, turn the hand wheel again to be sure it is picking up the thread without binding and sew.

Bobbin thread not being picked up

This unfortunately sounds dismally like a timing problem. When a sewing machine makes a sudden mechanical stop as when a needle is bent slightly and hits the needle plate, sometimes the other machine bits revolve along further causing the needle to be introduced into the hook either to early or to late to catch the thread.

To test this, remove the thread, the needle plate and and the bobbin case. Replace the needle with a brand new one. Yes, again. Revolve the machine by hand via the balance wheel and watch closely as the needle goes into the hook region allow it to it move down and then just start to move up. If the tip of the hook is not pretty close to right behind the needle than it is more than likely a timing problem.

If the tip of the hook is behind the needle in the scarf (the slight hollow on the back of the needle) than it is not timing. Thread the machine normally like it is and watch what happens as you manually turn the machine via the balance wheel. The thread should catch and be pulled around the hook and let go.

Try this and then either you figured it out the problem or contact me again. Either way please vote. Thanks

Loud noise while sewing

Could you let us know which machine this is.....

In the meantime....the damaged bobbin is not good, replace it/them........if you have a top loading drop-in bobbin, check for needle damage on the plastic bobbin case (remove needleplate to access).

If there is evidence of needle strikes, if mild, you could try to use very fine wet & dry emery paper to smooth, if severe, buy a new bobbin case.

There may be a load of lint under and around the bobbin case too, remove and clean up this area. If very dirty, use methylated spitit on cloth or cottonbud (QTip) to remove grime (don't soak)
