Repair on old Singer
My Mom's old Singer Zig Zag 457 stopped working and I am trying to fix it. She needs to finish lining her curtains. Better late than never. I hope someone here can help.
The bobbin stopped spinning. I flipped the machine over and took off the bottom plate. You see this (I removed the belt):
The wheel under the bobbin turns freely. The wheel on the right, that is turned by the motor, feels like it is spun.
I can feel the "driveshaft" turning inside of the wheel.
How do I take it off? There are no screws.
What is it called, so I can order a new one?
Sorry that I don't know the termanology. I hope this makes sense.
