Plastic Singer Apollo Bobbin Case
Sometimes the original Apollo bobbin case was dark Grey in colour, but in newer sewing machines it was Black. Its easy to fit and easy to damage. If the apollo bobbin case is too loose or jumps out of position it will need replacing. It does wear out or it often gets damaged by the needle when it snaps...! so take care.
To fit, slide and lift off the needle plate, slide the bobbin case retaining clip out the way (to the left) and lift out the plastic case. Lay the new apollo case into place and move the retaining clip back into place.
