My brother sewing machine won't load the thread for the bobbin.

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.

first you must make sure the winder shaft is turning by moving it to the right a little and see if you can turn it by hand.
If it is turning ok then there is a rubber ring on the other end of the winder shaft and it should come in contact with the drive which turnes it ,if it is worn it might need a new rubber.

Hi again,

Well we finally downloaded a service manual that cost a few bucks, then finished getting the machine apart, then found a small rubber O-ring that had obviously gotten hot when spinning after the tangling of the thread on the bobbin stem. You could see where the heat had melted tiny teeth marks in the ring and it was stretched out of shape. It and yours too will need to be replaced.

If you or someone you know is mechanically inclined, you will need to take five screws out of the back including a hard to find one under the foot raising lever (lower the foot), then one form the front that is under the thread cartridge, and you will have to remove the bobbin winding plate cover which is held by one small screw, and then remove a small screw from the support bar.

Good luck!

Rick

Also it is quite possible that the small circuit board (P-print) just below the bobbinwinder that the motor plugs into has gone bad.

If you turn the handwheel, can you see a metal ring rotating around the outer edge of the bobbin case? If not rotating, broken gear or timing belt off.
If that ring is turning, remove the needle plate and bobbin case. As this ring now rotates, you will a finger on the ring that will pass behind the needle from right to left and it should catch the thread from the eye of the needle. If this finger, the "hook" passes above the eye, you have a timing problem.

Let me know.
