I have an old Kenmore 10 sewing machine .The bobbin winder won't work after disengaging the clutch ,and the needle still goes up and down.

The issue you are describing with your Singer 9960 bobbin winder could be caused by a few different things. One possibility is that the clutch is not properly engaging or disengaging. Another possibility is that the bobbin winder belt may be loose or damaged, causing the needle to move up and down and making noise while winding the bobbin. It is also possible that there may be a problem with the bobbin winder mechanism itself.
I would recommend checking to make sure the clutch is engaging and disengaging properly, and check the bobbin winder belt and mechanism for any signs of damage or wear. If you continue to experience problems, it may be best to consult the manual or contact the manufacturer for further assistance.

Sandy, I'm not familiar with IZEK machines, but it sounds like the bobbin winder has not correctly disengaged. Put it back into bobbin winding mode and run it (no need to wind a bobbin, just check that the bobbin winder turns), then stop and disengage the bobbin winder and try sewing again. Hope this solves it for you. If it won't turn the bobbin winder either then it may have slipped or broken the drive belt and you will need to take it to your local sewing centre.

there is a part In the machine that work the bobbin winder that is not functioning like it should, a repair technican can tell you why

it's possible that there is a part inside the machine that could be broken, it would be a good idea to have the machine checked.

bobbin winder is the little spindle on top usually right side above the flywheel. you need to move it left away from the stop as this engages the bobbin winder and disengages the needle movement. your manual should show this under Winding a bobbin. these machines dont have a clutch on the flywheel, just moving the bobbin spindle declutches

there is a clutch you disengage it to wind the bobbin and you engage it to sew. instruction book?

hi there,
on my manual 1581 kenmore show figure on how you thread your bobbins and upper thread.
to thread bobbin insert the thread on one hole of winder holding thread and rotate thread on counter clockwise rotation several times, loop the thread on tension thread and insert bobbins winder on winder shaftat top of your sewing machine push the latch to lock bobbin winder
pull the handwheel to disengage the clutch and to move the winder free rotation.
press the foot pedal to run your winder and thread your bobbins be sure on counterclock wise rotation.
if winder is full of thread this will automatically disengage the shafting winder from clutch.
insert winder as in fig. check the thread direction

on figure hold and insert bobbins on shuttle race assymble.

on figure show upper threading.
follow the red thread on figure.

I have a Kenmore as well ,I hope that this will work for you ,too bad that I don't live close to you otherwise I would give a hand. This is the way I fill the bobbin on mine. Mine is located on the top right ,I put the thread into the bobbin hole leaving a small piece of thread hanging for me to hold when I begin the winding, I pull the wheele out to stop the needle from moving while winding, when I am done just push it back in .I run the thread from the spool into the top left it looks like a U turn with a screw go around that without winding just pull it into the bobbin hole. press the foot control and it will begin winding .
