Rotary Hook with Bobbin Case 4127470-03 for Pfaff 1471, 1530, 2010 & 7550

The rotary hook is the part below the needle plate whose point catches the upper thread loop and carries it around the bobbin case to lock each stitch. 4127470-03 is that hook supplied together with its bobbin case as one assembly, so a worn hook and a tired case are replaced at the same time.

Pfaff shared this assembly across several generations: the 875 and 1471, the 1530, the 2010, the 6230 Tiptronic and the 7550 are all on the list. Earlier catalogs number it 4127470-02 or 91-106380-91, and those refer to the same assembly. Replace it for a burred or chipped hook point, skipped stitches that persist after a new needle, and thread shredding at the bobbin.

After fitting a new hook the hook-to-needle timing and needle clearance need setting, so keep your service manual handy or let a technician install it. Look for your Pfaff's model number in the list below; Tiptronic, Expression and Creative names are given where the parts lists use them.
