Viking Epic Bobbin Winder Stop #68017356

• The “Bobbin Winder Stop” (also called “Eccentric Winding Stop”) is a small replacement part for certain sewing machines — specifically older or high-end machines from Husqvarna Viking (e.g. the “Designer Epic” line).

• Its function is to stop the bobbin-winding process once the bobbin is full, preventing overwinding, thread tangling, or damage.

 Why it matters

• Without a properly functioning winder stop, your bobbin might continue winding even after it’s full — which can lead to uneven winding, thread jams, and poor stitch quality when you sew.

• Replacing a worn or broken stop can restore automatic winding-stop behavior, saving you trouble and protecting your machine.

What machines it fits

• According to the supplier listing, this part is “guaranteed to fit Viking sewing machine models: Designer Epic” — so if your machine is in that line (or compatible), it should work.
