Singer 6620C

  A friend picked this machine up at a local auction.

 Before giving it to his granddaughter, he asked me to check it out and make sure it is functional.  We knew right off the bat that the bobbin case is missing but they are available new and not too expensive. In fact, I have a used one in the parts bin. The machine was making an intermittent grinding noise when running and watching the feed dog, it appears to be stuck in stretch stitch mode, regardless of the position of the selector knob. I couldn't immediately isolate the cause of stretch-stitch-only mode, so I started looking for the grinding noise. Turns out the vertical gear in the upper section has a LARGE crack and its mating gear was skipping a few teeth every time it came around to the crack.

That gear is so far down in there that much of the mechanics above it would need to be removed and reinstalled - a task I was not looking forward to. I did remove the camstack to get a better look at the cracked gear and found that the camstack gear is also cracked.

After discussing the cost of repairs with the owner, he told me to just keep it for parts or dispose of it.  I don't normally work on machines this new and there is no need for me to find a place to store parts that I will probably never use.  So, I am offering the parts to the readers of this blog.

There are lots of good plastic parts - all the panels, the slide-on bed extension, power cord, knobs.

As for internal parts, the motor seems to run fine and everything else looks good. If you want anything, email me at oldsewingmachines@gmail.com and we can work something out. I got it for free, all I have invested is time so all I will want for any parts is postage and a little to cover the cost of packing materials.  I will keep the machine until October 12 to give everyone a chance, then on the 13th, it goes to the dump.
