Bobbin casing keeps popping out - unable to use machine

SOURCE: bobbin case case keeps jamming

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?

Usually when this happens the bobbin is in wrong, replace it make sure the thread is going out the right way, make sure there is no lint or small pieces of thread around or underneath the bobbin area. Make sure you thread it with the foot up. Also make sure you are usng the right bobbin for the machine. They can easy get mxed up.

From what I gather on other sites, your thread has to be threaded under tension.... You have to make sure you hear a click when your bringing your thread down to the bottom of the "arm". Also, I thought the bobbin case was rather loosely held in its place, I adjusted this by unscrewing the black plate and moving it over just a smidge. The bobbin is supposed to have some wiggle room, but it kept popping up and making the tiny adjustment seems to have done the trick....for now...

unscrew the black plate that holds in the bobbin case and move it over to the left just a little bit, but make sure there is still clearance between the lower right corner of the case and the plate. The case should be able to wiggle a little, but not so loose it can pop out..

Raise the needle to it's highest position and the case should go right into the shuttle.

Refer to the maintenance section of the manual for your machine.

If you do not have a manual, you can get one at the Brother website.
