Singer 9000 How do I thread the bobbin on a 2003 model Singer 9000?

SOURCE: threading the bobbin

Threading the bobbin - winding thread onto the bobbin.

Position the new empty bobbin onto the vertical bobbin rod next to the end wheel. Click the rod to the right to engage drive. Hold the outer end wheel with left hand, and rotate the inner wheel anticlockwise by about a 1/2 turn (it stops) this removes drive from the foot and needle mechanism.

From a spool of thread on the top, thread to a loop/post on the left on the top. Then back to the bobbin you want to wind. Thread through a hole from the inside-out. Hold the thread vertically above the bobbin while you depress the footswitch to start winding. Let go when it's turned a few times.

Move bobbin shaft left, and tighten end wheel after winding enough.

Fitting bobbin-

Move footplate towards you, insert bobbin in hole so that bobbin rotates anticlockwise when thread is pulled, then pull thread into the fine notch towards you. After this position thread away from you, and slide the footplate closed.

To start / load thread. Hold the end 3" of the thread through the needle behind the sewing foot. hand crank towards you to sew first stitch in air. This should retrieve the lower thread - which you can catch with a handy pair of scissors. Then pull both threads rearwards - ready to sew.

These machines are timed by belt and go out of time a lot. Check and see that when the needle passes through the plate and travels upward 1/8" at this point the rotating hook should be right behind and above the eye in the needle,my guess is that it is out probably 1 tooth on the timing belt and can usually be corrected by removing the bobbin case and holding the rotating hookk with on ehand and forcing the handwheel with the other hand which will cause the belt to jump a cog and should put your machine back in time I hope this helps

I believe you have a broken gear. These are difficult to repair on your own.
