Broken Hook Gear Repair - Singer 700 Series - Part 1 - Removing and Assessing
ฝัง
- เผยแพร่เมื่อ 15 ส.ค. 2024
- While I was recording the last video, the Singer 760 I was using stopped sewing all of a sudden.
What I thought was a thread jam was actually a broken hook gear.
I remove the hook and we get a good look at the broken gear and how it is attached to the hook.
At first I thought I would just use another hook from a spare 760 that's got a broken cam stack gear, but I have plans for that machine. The hook gear is not available at the moment because of Covid-19 lock-down so I thought it would be a good idea to try and fix it.
All the pieces of the gear are accounted for so I have a go at piecing it together and using epoxy glue to repair it.
It looks like most of the gears are still available for these models.
One place you can find these parts is here - www.vintagesin...
The 700 series Singers are precision made in Germany and are beautiful and very functional, not to mention easy to use.

Wow! Respect sir for repairing those disintegrated gears…
You are the best
Yours video are really clean and perfectly explained
It's really useful and in my case I was able to perfectly synchronize my machine
Thank sooo much !!
Glad it helped
I recently bought my wife a singer 774 model at an auction. When I got home the needle was positioned to the far right yet the needle position dial indicates Center. Unfortunately the needle isn’t bent. Is the needle centering adjustment difficult? It uses a vibrating mechanism arm that I was looking at to see any obvious screws but didn’t see any obvious adjustments. Thanks for your videos they are a help.
I replaced mine with one I got from ebay (the store is called evernice). As others have said it's a press/interference fit so you need to cut the old metal collar off. I did this with a dremel, making multiple cuts. To fit the new one I put the hook in the freezer overnight and when I was ready put the new gear in some hot water for a few minutes. I pressed them together in a vise. You have to be really careful not to bend the hook, I used a small piece of wood to make sure I was applying force to the base and not the rim of the hook, and a small socket to make sure I was applying force to the metal part of the new gear.
Thanks for the reply. You have done exactly what I was thinking about trying. Thanks for confirming it works. I'll try it.
I saw your comment and found the part. Thank you. Have it now. which part exactly did you cut off? My new gear is a loose enough fit on the hook shaft. Just wondering what part will keep it put ? Im assuming you cut as far as the gear shape? Thanks for the help so far
Edit: I see what you mean by collar. Did you remove the metal bushing from your new gear and press the nylon/plastic gear onto the existing bush on the hook?
Hello could you please send me some photos? for example which dremel did you use? We already tried different things. I have more than 20 machines to replace in our sewing project Paraguay and it would help me a lot and save me a lot of money if I could use the old hook.
Thank you for sharing you experience. I am reparing an old 700 touch & sew. I have a problem with the bobbin case position finger screw - Left hand thread- ( broken screw). Can you share where I found the replacemet or can you make a video for repair that.
Clair explanation, good job sir
Thanks
Thank you so much for this detailed video. I was able to change my 708. I do have little problem with the sound and the hand wheel not rotating completely without the motor... I hope you do make a video for that too 🤗🤗🤗
Amazing video!! That’s exactly the problem that I have with my singer, where did you buy the replacement?? Thanks a lot
Hi i found a replacement cog but its got a metal part in the middle and wobt fit right?
Central Michigan sewing supplies. Have a good selection of parts for touch an sews
Thanks. I'll take a look.
They have the bobbin winder cam but not the hook and gear as far as I can see.
I found the parts in the 700 series touch an sew section. They were pretty expensive though
I found the hook gear for sale on line so that's a better option than repairing the broken one. I thought I'd give the repair a go anyway.
@@InStitches can you please explain how to assemble new hook gear?
I have a long time im asking how can I get Hook Gear for my MaschineSinger 700
Hello, I have a Singer 764 with the same broken gear which you were able to glue together. However mine is broken in many pieces, Is a replacement available anywhere? Kasper Janse Pianola Museum, Amsterdam
great video had me super excited to be able to fix mum's singer 784 . The screws for the feed dogs put a quick stop to things. Simply impossible to undo :( If anyone has tips, I'd be very grateful!
Thanks. Yes they can be very tight. The best option is a screw driver with a long shaft and the correct fitting blade.
Yes! You can order replacement gears directly from Singer. I just got some last week....$24.95 US
Can you give me the address please
I have replaced the hook gear following this excellent video. Thanks for that! However it still wouldn’t sew with birds nesting. So I took off the tension and replaced the springs... better .. but still not right. I add photos in the hope someone can suggest what I do now! Can’t add photos buy
T top stitches look ok and underneath looks ok for about 8 stitches but then tightens up and top thread forms loops and it sticks.
Great work, is there a video how to remove the gear from the hook with a Dremel?
For people who are lucky like me to have access to a resin printer
www.thingiverse.com/thing:2799794/files
in my case the teeth was a bit to high so I sand 0.5 mm for clearance
-> no need to remove the metal ring just "click and fit" in place
Great video. Do you have a video showing how to replace/repair the nylon gear in the Bernette 334D? This gear on mine has split and probably can be epoxied but I'm not sure how that gear drives the other parts. Service manual or parts assembly diagram would be good, but i guess this kind of stuff does not exist. Any advice/help appreciated. I can upload a video of the mechanism if that would help with you giving advice.
Cheers,
Andrew
Hi, great video! Thank you so much for sharing your experience. I am reparing an old 764 with exactly the same problem (broken gear). Any suggestions for screws of the feed dog that don't come out?
Thanks and if the screws are very tight you may need a screw driver that's a very good fit, of high quality and a long handle helps. Don't push too hard down on the screws unless you support the feed dog from underneath.

I commented on another video about the bottom thread not catching and this is the problem it's really hard to unscrew everythinf
Wow! Totally different set up then the US and later models
I must look into the US models. The only one I have is the 301A.
In Stitches yes! The 750, 758, 774,776,770
In Stitches ohh yea look into the model numbers I wrote and you’ll see they are totally different mechanically. I think it’s very interesting
@@chrispeak9893 Thanks - will do.

Hi, your video is great, I managed to follow this for my mums Singer 720 Touch and Sew but I had to drill out the grub screw as it just wouldn't move and I am now having issues replacing that grub screw. My question is what other parts in a 700 series use the same size grub screw that I could search for?
Hi. Sorry but I'm not sure. You'll just have to try some. Thanks.
Since writing this comment and in my continued search for parts for the Singer 720 I've had a replay from a lady in Norfolk UK Helen Howes - www.helenhowes-sewingmachines.co.uk and a gentleman in Lincolnshire UK - www.sewlincs.co.uk/ who have many Singer parts so its looking very hopeful.
the gear bit is about $12u.s. dollars on ebay but not sure if post to uk
Terry Fielding-TandT sewing is my go to for parts, manuals, advice. He’s online and is located on Guam. Love your videos!
Thanks. Can you please post a link to their site? Do they have the cam stack gear available. I have found a supplier but they are quite expensive.
TandTrepair.com. Don’t know if that particular gear is available.
...help!!! I need help identifying how to install this particular 700 series sewing hook:
Singer Touch & Sew Bobbin Case Repair Kit Part# 163300
Very good, Marcos : Brazil
Excellent video, many thanks! We have acquired a 720 with exactly the same issue, but we can’t get the nut at the bottom of the shaft of the Bobbin winding disc undone (3:09). It seems to rotate freely in either direction, so I’m guessing the thread is stripped. It looks like the only way to remove it is destructive, by cutting the nut off with a Dremel, unless there are other options that people can suggest.
I can source the hook assembly easily to fix the gear issue, but the bobbin winding disc is another matter - do you know if there are replacements, or if they are known by any other names or part numbers? My Google-fu is letting me down at the moment (although it did bring me here so not all bad!)
Heat the nut up with a lighter and try get it while its hot.
This video ALMOST solve my problem...but not fully:/. I have a ‘bobbin hook’ and an oval shaped nut that fell outta the bottom of my 750 machine and cannot for the life of me figure out how to put it back on. I’ll keep perusing your channel but invite anyone’s help to aid me in my journey! I’ve got pics of what fell out but need an email to share them to...
Good epoxy fix-I hope that solves the problem!
Good morning! I pretty sure that your machine with the broken cam stack will straight stitch my 758 doesn't have a cam stack it has no built in stitches every other stitch comes from the fashion discs like zig zag that came with the machine so I'm thinking that the discs will still work as well, the cam stack represents the built in stitches
The cam stack no longer turns so none of the cams, including the built in ones will function.
@@InStitches oh dear doesn't sound good
Hi, I have found many of these nylon replacement parts for these great old machines. I found a mail order company in American Samoa. TNT repair. Good people. I hope this helps. Thanks Ken.
Thanks.
Do you have a link to the parts place you mention?
Hola mi maquina es magic bobbin modelo zig zag EE lujo 690u se le partió el botón interruptor de la bobina y soy de Venezuela, aquí no lo he podido conseguir, eso se puede reemplazar???? Agradezco tu respuesta
Sorry, I'm not sure what switch you are referring to. Could it be the bobbin winding engaging lever?
Bonjour. Merci beaucoup pour vos vidéos. Ca m'aide beaucoup à réparer ma singer 760 moi-même. Je cherche le manuel de cette machine à coudre. Si vous lavez pourriez vous le transmettre ?
Merci pour votre réponse. Elise .
Вот эти обе шестерёнки мне нужно заказать,и я не пойму как мне это сделать?Вы в какой стране находитесь?
The parts for this machine including the nylon gear for the hook are new available in the UK
Can you give me the online address please
@@TA-sx4uh www.singermachines.co.uk/sewingmachineparts/gears/singer-hook-gear.html . I'm in the UK but I have just received and new Hook from another Supplier and I'm awaiting a new genuine bobbin drive from the USA. There are also numerous pattern parts available from a variety of internet sources if you search around!
Wooo
Hello, thank you for this very detailed video. I have a 706 model, and everything goes fine until 4m25 when you can remove the main piece while it's stuck on my sewing machine. I tried to push from under, and pull from above with a small tool, it moves a little, but there is something blocking this piece from being totally removed like yours on the video. I don't understand, or can't see what to remove so that it would unlock this mecanism.
PS : the other piece you unscrew at 4m50 is stuck too, I put some special oil in hope to unjam (?) this particular screw. Any advice about that ?
Anyway, your video is very helpfull and give me hope to repair my grand mother's machine, so that it can be used again :D.
Try penetrating oil like CRC 556 or WD40 and let it soak over night. Also warm the machine to room temperature and then work away at gently trying to un-seize the parts.
@@InStitches Hello thank you for your answer ! the penetrating oil worked fine and I found a hidden screw that is not on your version of this 700 series and finally I was able to remove the main part with the broken gear. I have all parts of this old gear but they seem very fragile, and there are very small holes when I assemble the piece again. I'll try to glue them like you did, and we'll see what'll happen :D.
@@gladousol Good luck! Let us know how you get on.
@@InStitches Hello, a little update. It didn't work, the pieces were too damaged, and in the end, it didn't perfectly fit so it didn't turn smoothly :/. I found entire replacement pieces sold on amazon or local seller, but I'm still having the issue with the central part that I can't remove from the hook and I can't find any video explaining how to do that (the piece you remove at 4'25). On every video, it seems so natural that it's not a problem :D. I'm starting to think that the 706 model is a little bit different than the 760 or any "independent" machine (mine is build-in in a wood table).
Anyway, thank you for the video, it helped me a lot!
EDIT: My neighbour find out what was wrong with the central piece, and it's all good now! (It was a little bit distorted so it was blocked on the axis)
@@InStitches Final update, my sewing machine is working again \o/ Thank you again for your very detailed and descriptive video :).
Why in the world would Singer or any other sewing machine company put PLASTIC type material in such crucial parts as gears? Planned obsolescence? My mom had a Touch and Sew machine and HATED that thing. She called it Touch and Tear Up. She wished she had NEVER traded in her old black all metal Singer.
It seems it was common for companies to put plastic gears into high quality machines of this era. I often wonder if was a way to quieten the machines down? I guess you could say it's planned obsolescence but I have 700 series machines that are still going strong and they're 50+ years old.
Plastic in some cases is preferential to metal. It reduces environmental noise (on the ears) and vibration on the machine by damping vibrations so it makes much finer stitching possible. High quality plastic will beat low quality metal gears over time. Plastic is also semi-self lubricating, so it makes for a much more professional and high end product for this application. Designed very well, not for obsolesence - as can be seen by the fact they are still in use today not in landfill!
All that. And it's better this gear breaks than some other worse part of the machine
I replace these gears with 3d pet printed ones. Works very well. Surprisingly only the gears on the rotor break apparently singer uses different plastics.
Great video! I have exactly the same issue and unfortunately, half my gear has disappeared! Can you share where you found the replacement?
To elaborate, I can see you shared a link to Central Michigan above (I believe the part is #153021G ?) and I can find them on eBay (cheaper!) but none seem to have teeth to grip the hook? I see teeth at the base of the shaft / on the hook when you remove the gear (7.28). Surely the new gear needs something to grip to that?
As per you recommendation in the description, I explored Central Michigan Sewing Supplies, however, the only hook gears I can see on there don't have teeth to grip the hook i.e. there are just teeth for the gear side. Will that work? www.vintagesingerparts.com/collections/singer-touch-n-sew-700-series/products/singer-hook-gear-part-153021g-fits-models-700-702-706-708-720-722-726-740-760
Thanks for your kind comment. I think the teeth you're referring to are part of the broken gear. It looks like the metal collar with the teeth on in is press fit onto the shaft. I haven't fully explored this yet but I have one on order so keep an eye out for a video on this subject.
@@InStitches I look forward to the next installment!
Have the same problem, don't know how to adjust new gear.
A job for a 3D-printer
Thanks. That could be worth looking into.
The only worst thing about this machine unfortunately
