Bobbin winder stopped working anyone know the number of the O Ring to fix this dude? Let me know how many screws and where they are at and the part number of the O ring please. Thank you in Advance, Karen
Replacing the bobbin winder rubber ring.
Next, WITH CARE , lever round the tray with a thin blade and use a small screwdriver to ease it out of the case; there are 2 bits that stick out more than the rest.
TAKE CARE NOT TO DROP THE SCREW INTO THE WORKS!. A piece of sticky-tack on the end of the screwdriver helps here if the screwdriver is not magnetized.
The bobbin winder mechanism is held in by 1 screw - take this out and you can then easily replace the rubber drive ring -(which you have providently ordered)
I took both my CS 8080s apart last week to replace the drive rubbers. The first took nearly 1.5 hours, the next 1 hour as I knew what I was about.
Thanks Roger, where were you in June when I already tore my machine apart? :) Thanks for the valuable tips, those should be super for others who encounter the same problems we all eventually have. However in my case my O ring melted completely and I had days of clean up to do. I didn't mind taking apart the cables that was easy for me with fixing my own PC's etc. What I didn't think to do was the drop of oil, wish I had your response earlier while the machine was apart, that is a great tip. Now I am thinking the best plan is to get a stand alone bobbin winder on not deal with this issue again. Also as a first clue before a total melt down, if your bobbin is not winding tightly, clue will be bobbin thread binds up while sewing, then you need to replace the O ring. Any of those bobbins will need to be unthreaded after your repair and do a new bobbin rewind. If the bobbin thread feels soft and springy, then it is a poorly wound bobbin and your O ring is shot. Thanks again Roger. Karen
Here's pictures of the "hidden screw" and the gooey rubber ring

You can find an O-ring at any auto parts store, or by googling your Serial number and part.
I usually just figure it out as I go along when pulling stuff apart.

Yes I did all that you mentioned on gut instinct, however that was back in June. My O ring had totally melted so I had hours of goo to clean up and then replace all the pieces back again. What point I didn't think of was putting in a drop of oil, which I always did with my old Singer. Wish you had read my request back in June, but I am sure you will help the next person with this problem. I think the best thing to do is get a separate stand alone bobbin winder to not deal with this again in the future. Thanks for the suggetions.
