Question about Yamata FY910
The plastic bobbin holder keeps shifting and as th eneedle is lowered past the plate it hits the black plastic bobbin holder and breaks.
The bobbin case rests on the lip of the hook and is is held into place by the position bracket. The position bracket is located at about 5 o'clock and has a small square end with a buffer spring. It must be positioned to hold the bobbin case securely and also allow the thread to pass through freely. It may be out of adjustment but may not.
If the bobbin case has turned, it is very likely to have suffered damage as it is made of a soft carbon fiber material. It not polished off, these damaged areas can snag the thread and jam the machine and create tension problems. Some gouges, burrs and needle punctures can be carefully sanded but you may need a new bobbin case. Use a 1500 grit sandpaper to smooth off the rough edges.
