I have a singer 9018DT and have purchased a new black bobbin casing, and after only 2 or 3 small projects (hemming) maybe 4 projects, anyway, the black bobbin case is broken AGAIN!!!! can you help me?
I have a Brother XL3500 machine..and the needles keep breaking because they are hitting the bobbin case...Please help me? Should I get a new case? I do a lot of quilting..so have to clean often..and maybe when I remove and put back..it isn't aligned perfectly?? Dee firstname.lastname@example.org
Nope...it didn't work...I got the new case...and still keeps breaking needles...ready to throw the machine right out the window...3 floors up...I think they sent the wrong case...and on e-bay...another vendor wants 36.95 for a case...don't think it is worth this...only paid 150.00 for the machine at Walmart...personally...plastic parts are terrible...I still have a Singer from 1953...and it still sews like a charm...but just goes front and back...no frills...but the oldies are better!

Using a doubled piece of fabric similar to what you have in mind for your project, sew a seam on the diagonal-pulling the fabric on the diagonal to break the threads. (Ideal tension would either break neither thread or break both threads. So, a single breaking thread signals that the tension needs adjusting.)
Snap out the faceplate to remove it & to gain access the bobbin area below the sewing needle.
Remove the bobbin case & bobbin-lifting the hinged latch that you would to wind a new bobbin-leaving the bobbin in the case. (You need it in there to feel the tension as you adjust it.)
Using a small screwdriver, very slightly turn the screw on the side of the bobbin caseclockwise to increase tension; counterclockwise to decrease tension.
Pull the bobbin thread while you hold the bobbin in its case & feel the thread's tension. Too tight of tension would prevent the thread from dispensing (& possibly break), but too loose of tension would allow the bobbin to fall out of its case.
Return the bobbin case to the sewing machine & close the faceplate.
Repeat this whole routine from Step One on the doubled fabric. Stitching should run along both the top & the bottom in the same way-locking in the center. A diagonal pull of the fabric should show which thread(s) break(s). Repeat Steps Two through Four to only adjust the screw aside the bobbin case in order to allow the threads to lock in the center of the fabric with both threads having the same break or no-break result.
Bobbin thread breaks
1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesn't stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly
2. Lint has collected in the bobbin holder
3. The bobbin is damaged & doesn't turn smoothly
4. Lower thread tension is two tight

Go to the home page
Go to customer service--click on it--it will show a small menu--click on instruction manual
In the box put the model number (example 5528) & click search and it will bring up the manuals that are available
try checking the bobbin case for burrs & make sure the the small bar on the bobbin case is not bent make sure the bobbin case is in correctly
A sewing machine operator can often help themselves when their machine does not operate properly. Here are some simple instructions, which if properly used can save time and mechanics service calls.

When you insert the bobbin case, make sure the "knub" on the bobbin case (#1) is just to the left of the position finger bracket (#2). It should sit in there nicely and you should be able to spin the hand wheel freely.
On the right of the black bobbin case there are two screws, you can slacken those screws off and move the bobbin case nearer to the guard leaving enough room for the thread to pass through, if the needle is hitting the bottom you may need to retime the machine.
Make sure the bobbin case sets sort of on top and not under the ridge of the metal ring. There is a small latch on the upper left of the bobbin case. It is metal. rotate the latch to cover the bobbin case and this should stabilize the case without making it immobile
I am having somewhat the same problem with the exception that my needle did not break. I've cleaned and oil, but the bobbin case and projection positioned spring is not communicating to allow sewing to continue. The thread keeps jamming and the bobbin raises up the plate. So, what else am I to do?
