I HAVE A BROTHER SEWING MACHINE XL3750 AND I NEED TO KNOW HOW TO PUT THE 2 PLATES BACK ON THE MACHINE UNDER THE NEEDLE AND OVER THE BOBBIN CASE.

SOURCE: Bobbin Case

ok Sim this is a bit tricky but not to tricky first turn the handwheel toward you until the hook is at one o clock postion then slide the case without the bobbin in into the hook area you may have to work the handwheel back and forth alittle but it should slide in just remember that the case should ride in the rim. also take the needle out first that way you wont get stuck trust me it happiens.

SOURCE: while sewing the bobbin case moves, wheel locks up, needle locks

Im not sure if this will help but thought I would pass it along. My Pfaff 6122 tells me to check bobbin for thread unrolling clockwise before you place it back in the machine. I had mine turned to un roll counter clockwise, this is wrong, the bobbin will fall out when you pull on the thread while you are holding it in your hand. You may just keep putting it in backwards. Hope this works for you. J.R.

No problem, go to a Brother repair shop and buy one.

Double check to see if the bobbin is in upside down and the thread is feeding from the bobbin spool in the wrong direction.

I did this once after several years using the same machine, some days are just not as easy as they should be!

SOURCE: I have a CE-4000 model. In the middle of sewing,

When you put back in the bobbin case, there is a little "knub" that sticks out with a flat spot on the right (on the top side of it) that you need to ensure it rests gently to the left of the position finger bracket (silver metal piece, in the square of the bobbin case area its on the right closest to you).

When you put in initially, it was probably twisted clockwise and there was a gap between the knub and the position finger bracket and when you put the needle plate on in jams that bobbin case in that position and the needle just takes chunks out of it..

You might need a new bobbin case, try sanding out the needle marks with sandpaper.
