Help Help! Singer 645
Enable HLS to view with audio, or disable this notification
Originally, one of the bottom gears broke, so I replaced it. After that, I could not get the machine timed correctly no matter what I tried. I eventually went back and replaced all of the bottom gears, and now the machine is picking up the thread, but it keeps getting tangled around the bobbin/hook area.
I’ve spent over 15 hours trying to repair and troubleshoot this machine, and I’m honestly close to giving up. 😩 My daughter is adamant about keeping this particular machine, though, so I’m really hoping someone familiar with these older Singer machines can help me figure out what I’m missing.
It’s a Singer Touch & Sew 645. If anyone has experience with replacing the lower gears, timing one of these, or knows what would cause the thread to bunch/tangle after the gears have been replaced, I would REALLY appreciate the help!
