Nice video on these old girls. I’m lucky enough to have an early 1966 that has all metal gears. Along with the raised eyebrows I get the “my mom had one.” They’re one of the overlooked gems. Once served and or repaired they are a fun machine to use and a little work horse, well worth the time spent to get them going. Thanks again for the time spent on this video.
Excellent presentation and links. My wife bought the machine for me from a thrift shop and I wanted to make sure everything was lubricated and working properly before I sed it. Thank you for this work.
I kust purchased this machine at a thrift shop for $10. It's so nice and sturdy but I wasn't quite sure how to thread it, so this video helped a lot! I'm sure I will refer back to it when I need to fix anything on the machine.
very nice video and well presented, your teaching skills are just brilliant. and thanks to your very professional husband. currently working on a singer confidence..
Thank you so much for this video. I used it to resurrect a 628 which belonged to my wife’s great grandmother. Ours is interesting in that it doesn’t have nylon gears. At some point in the distant past someone hot rodded the machine with a metal gear drive train. Down side was they lubed it with axle grease so it was completely locked up. Thank you so much for the guide! You should buy some of the funky accessories like the circular stitcher and buttonholer and make a video about them. I was able to find every accessory they ever made for this machine on a popular auction site for about $50.
Wow! That's very cool. Sorry for the late response. I had an emergency. I would love to make a video about those things. Axle grease? That's crazy! So glad my video helped you!!
It was not "hot rodded".. The first production models had metal gears. There is no way the machine could have metal gears added after production, because the gears needed to be "factory installed" only. The gears were hand meshed and "run in" with an abrasive compound at high speed and rinsed with Varsol.. It seemed common for either repairmen or "husbands" to get the grease gun and lube the machines. I have repaired a few that were very congealed with hardened cup grease..
I just got a 638 today, and to my surprise, it didn't work. Broken gear on the timing shaft. Your video showed me how to get to it, so I've order replacements and will replace the broken gear. Crossing my fingers that it works. I've examined my machine and confirmed that the spring you talk about in your video is connected at the same point next to the plastic square. The other connection is on a bar on the rear of the pivot point for the needle bar. I've take a close up photo, but cannot post it here. (I'm taking lots of photos as I believe this machine has never been cleaned or oiled. Thanks again.
Thank you for sharing your knowledge with us. Very informative. I have a 635 touch and sew and can't find a manual for it. Any advice where can I find one ? Thank you Greetings from California 😊
Hello and you're welcome (also from California)! The manual I have is a free download on my website at the following link. Just scroll down under "Links" and it's next to "Free Manual."

Thank you for this excellent tutorial. I have the 626 and will be replacing the gears. I have subscibed and saved this video but I don't know how to get to the links for manual and parts. Help please😊
You are welcome! In the description below I've got links for "Singer Gear Set" (Amazon set you can still buy), as well as "Free Manual" (a link where all these same links are available on my website. Does that help?
Got the gears in place and almost ready to do timing, but when I try to remove bobbin case to see hook area, I can’t get it out. Could it be that the feed dog gears are too tight? Would that cause a problem?
I'm not sure because we didn't have that problem. Without seeing a picture or video I'm just not sure. Look on the right side. Mine had a metal tab that held the bobbin case down.
My machine is missing the metal button next to the take up lever, I figure I need it but i cant for the life of me find what its called so that I can get a replacement? Also this is an amazing video thank you so much ❤
Oh! I wish we could share pictures here. If you have the manual, at least there's a photo of it and what it looks like, but there's no reference to a name for it. At all. But if the pin is still there, maybe you don't need the button? If you go to the link I'm attaching here and download the free manual, the picture I'm looking at is on page 7. lydiahawk.com/singer-model-628-touch-sew-deluxe-zig-zag-replace-gears-oil-loose-parts-set-timing-thread-adjust-self-winding-bobbin/

The early production models of #'s 620 -626 -628 all had metal gears. The # 626 was a home economics classroom machine, so it had metal gears longer than the others. By the fall of 1966, all of the machines had nylon gears..

I have a 648 thats built the same accept that top right horizontal gear has two micro size allen key holes that wont turn or release from the mandrel. I need to remove horizontal bar that goes to the knob so i can lift the mandrel with the stuck on gear out and throw the mandrel with the gear away so i can get a new one since it wont come off. Can't figure out how to remove the knob bar out the way.
We also had issues getting the screw loose. I think my husband finally had to take a screwdriver and hammer and beat it a little to knock it loose. It did finally come loose. Not sure of any other way to release parts from that area.
The top gear is held in with a cinch pin ( or roll pin ).. It can be driven out with a finishing nail, but the replacement gear will not fit on the shaft. I ended up throwing away my pristine ( and expensive ) model # 640..
I assume yes? Because it's a version of the 628. I don;t have those, so I don't know for sure, but I can't imagine they are so dissimilar of they share the same number. I hope that makes sense!
Without a photo I'm not sure. My machine is the only reference I have for this model. Sorry that I'm not more helpful. We had to start fixing our own machines after the pandemic and we are not trained in all things related to sewing machines, unfortunately.
@@LoisRose-g4ji think the tool is a pilot punch or roll pin punch. You should be able to get a set from Walmart/ harbor freight just make sure to get the right size
You are not inserting the bobbin case retention bracket properly.. Hold it at a 45 degree angle and slip it under the "hold down spring" that holds it in place. In the future, to clean the lint, flip the bracket up and to the right to remove the bobbin case.

Does the 628 have plastic or nylon gears? Rather than all metal?
Plastic. I read that they switched to plastic gears because the metal gears were noisy. Sorry for the late response. I had an emergency.
