My bobbin winding assembly is broken and I need the part

Make sure you have not disengaged the needle bar, such as when winding a bobbin. The manual says that when a bobbin is set for winding and the bobbin winder shaft is moved to the right, the needlebar is disengaged. If that appears to be okay on your machine, perhaps something in that mechanism is broken or misaligned preventing the needlebar from operating.

Probably something within the bobbin winding mechanism is misaligned or broken. You can probably still wind bobbins except you will probably need to slow it down, watch it, and stop the winding action when the bobbin gets near the filled capacity. Or, for ~$35, you can purchase a standalone bobbin winder (one brand name is Sidewinder) from JoAnn's, Hancocks, or even Amazon.com. (Also helps save wear and tear on your machine.)

it's possible that is could be a belt or some part could be broken
the machine needs to be checked to see why it's not wanting to
wind the bobbins

the machine should be checked by a sewing machine technican
to see what wrong with the bobbin winder, the assembly may need
to be replaced

Unlikely that a belt is broken. It is more likely that you don't have the bobbin spindle fully pushed to the right. Or worst case is that something inside, under the bobbin winder is broken.

Make certain you are passing the thread through the tension for the bobbin winder when setting up to wind the bobbin. Check that tension assembly for anything that could be stuck in it, preventing the assembly from putting tension on your thread, such as another thread. Wiggle the disc on the assembly to make sure it isn't stuck. If none of that works, disassemble that assembly from the top of the machine (NOT the tension you use when threading to sew!) and see if the spring inside is broken. If it is, replace the spring if you can get it, or the whole assembly if you cannot.

For $29 at Hancock, Jo Ann's or Wal Mart you can get a thing called a Side Winder that will wind your bobbins without using the winder on your sewing machine. It has the additional advantage that you can wind while sewing. I use it even with machines that will wind bobbins.

Hi Diane...you can wind bobbins while you are sewing your product, or you can wind them seperately. To wind them seperately, pull out the bobbin case, lift the presser feet up and lock them in the up position, undo the threading beyond the tension assembly. The takeup will create a birdsnest if you don;t pull the thread from it. Wind your bobbins, the re-thread your machine, insert your bobbin case, drop the presser feet, pick up the bobbin thread and sew away. If you need any other input, call me at 888-283-9640.

The bobbin winder will not activate to turn the bobbin or the thread will not wind onto the bobbin spool?

Sewing machines vary in the method used for bobbin winding.

You can find threading and bobbin winding guides at sewusa.com.

If the winder is broken, you can get it repaired or check into getting a Sidewinder Bobbin Winder as an auxiliary for winding the bobbins, which would be less expensive than the repair.
