Replace / Install a Missing Tension Unit on a Singer Model 401A

My 401A machine, "Trouble", did not have a tension unit when I bought it. I've gathered up spare parts and this video shows how to install and "zero out" the needle thread tension unit. Includes rust removal and cleaning and oiling of the tension unit when needed. A good tutorial to increase your knowledge of SInger tension units, their maintenance, installation, and adjusting. Singer models 401A, 403A, 404.

[@waynebach7189]

Thank you for your videos on the 401/403. I have two 401's that I got at D.I., one working and one labeled as a parts machine. I just stored them for years due to lack of time. I recently set out to convert my working 401 as a treadle/hand crank because I have several old Singers, including treadles and centennial models, but no zigzag treadles, so I made the adapter, and the 401 worked perfectly. Then I got to looking at the "parts machine" and discovered it was missing the bobbin cover, the red lever, the outer/brown zigzag knob, foot, but everything looked good and motor ran. I bought a foot and threaded up, but it would not sew a stitch. Thought it might be because of no red lever to control width, so I made one. It still would not sew a stitch. I fiddled around some more and decided it must be an alignment problem. That is when I discovered your videos. I followed your 401/403 timing video to the letter, and it now sews perfectly. It was WAY OFF. Someone had obviously monkeyed around, screwed up the needle depth and timing with the hook. I just finished your tension video so now I will go check that end of things out. Thank you for sharing your excellent knowledge!! I have since passed the info on to two friends who also have 401's.

[@andytubesewing1953]

Greetings, Wayne. I have to say I enjoyed your comment immensely. I bet the 401A makes a great treadle machine. It has some cousins in Germany, 401G, 411G, 431G, etc. that can be set up as treadle machines also, and viewers who have them tell me they work fabulously and they love having a treadle ZZ machine. Yes, for sure someone fooled around with that machine and got lost and decided it was now a "parts" machine; I've seen a few like that. It's great that you have rescued it. I'm glad you found my channel and the videos are helpful. I appreciate you sharing the info, too. How fortunate to have two Slant-O-Matics! Have looked at the serial numbers on the bottom near the nose end? Just wondering how close in age they are. If you ever find out their names I'd love to know them. Happy sewing, and take care in 2023.

[@wingwong888]

@@andytubesewing1953 Thank you Andy for your response! I am sewing with the machine now! :) Unfortunately I still have trouble with my the tensions. I followed your steps to start from 0 tension. But for some reasons this is the only setting I can sew without crinkling up the fabric. Anything higher than 0 is too tight. I don't understand. Basically the discs are barely touching to each other, the tension of the thread is only coming from the guiding hooks. I learned from another person's KZbin to adjust the bobbin tension with a "one ounce" force (tiding a bag of 1 oz beans), was hoping the thread tension would become the variable which could be easily resolved ... but no luck. Now I just set it to 0.5 tension. Lol. Oh, and I don't know what I did wrong, my tension knob turns by itself while sewing! It turns from 0.5 to below zero. Any clue? I need to get into zigzag stitches soon ... and which supposed to use even lower thread tension according to the manual. I wonder what I should do!! 😢 I would just like to say thanks again. You are so kind! 😊

[@andytubesewing1953]

@@wingwong888 It is late here now and I'll think of this tomorrow and find some testing for you to do, but it is a tension problem either the tension unit or how you threaded the upper threading or bobbin case.

[@andytubesewing1953]

@@wingwong888 So, there are a few things that can cause the "crinkling" of the fabric while sewing. I start troubleshooting one part or area at a time to try to isolate the cause. In this case, I'd also start with the upper thread tension assembly that you reinstalled. If you look starting @46:00 in this video you see I test by adding more and more tension to the dial and can feel the thread getting harder and harder to pull until it actually breaks, then I test the other way by turning the dial for lower and lower tension and feel the thread getting easier and easier to pull. Please do that test and see the results. If you still want help please email [e-mail] b/c it is a better way to communicate this type of problem than in a comment section. You are welcome to give me the testing results, any pictures, and videos you want to show the problem.

[@coeneschamaun1735]

This is an *AMAZING* video, thank you so much for taking the time to share your expertise!!! If I may, I have a different top thread path and tension assembly on my machine, a SeamMaster, model w-50. This machine I think came from a garage sale, and appears to be missing parts in the top tension assembly. Internet seems to indicate made by Simplicity. It has a brand label stating "US Patent Office", but I'm not 100% sure where it was made. On Internet, I found a picture of a Myer Victor machine that has the same threading path, and presumably a similar, if not the same, tension assembly. Unfortunately, information about Myer Victor is just as scarce as for SeamMaster. I do believe the Myer Victor machines were marketed in Australia, not US. This machine us very heavy, so I'm guessing all metal, so possibly 1940's...? It is a zigzag zag, and has the bobbin mounted underneath on the left side, if that matters. This machine doesn't have any drill ways or hole for thread guard, or check spring rest, so I'm not sure how those type of parts were mounted. I'm missing both springs, some type of keeper to keep the numerical ring from turning. I only have 2 disks, not three (why do you need 3, just curious). I have the plus/minus ring, and a knurled knob. Not sure what else might be missing. I would **LOVE** to have your expert advice, and I'd love to send you photos. I'm not sure how to send photos through KZbin, might need to just use regular email. Thank you so much for reading all of this! I'm frustrated, I'd love to get sewing, it'd be so easy to just find another machine, but this one is a challenge, hahaha.

[@andytubesewing1953]

I only work on vintage Singer machines. I know nothing about the machines you mentioned. Even some old SInger models did not have thread guides. If there are three tension discs it means the machine is usually capable of sewing with double needles or a twin needle. Two threads between the three discs then thru two needles. If there are only two discs then it is a single-needle machine. Earlier models did not have a numerated dial on the tension unit. Some models have the check spring rest/stop built into the housing of the tension unit. Here is an example: kzbin.info/www/bejne/qJrSg5uJl9SabLc and another: kzbin.info/www/bejne/a3OXfHStorCXe7c About your pictures; you have a youtube channel and you can post videos and slide shows on it any time you like. Some viewers save pictures in the cloud and give us a link to them so any viewers who are interested to help can see your pictures.

Hi Andy! Thanks for your very thorough video! My machine 401A was constantly breaking the upper thread. I have had some trouble with the tension on this machine (my grandma's machine that she gave me back in the 80's). I had it serviced several years ago for this reason but it never really worked well after that. Watching and learning on your video revealed the reason. Whomever (and he is no longer in business) serviced the machine replaced the tension assembly with one from the 201-2 model. I am trying to work out how I can adjust this to work on my machine, if possible.

[@andytubesewing1953]

It's too sad, Susan. Sounds like they took the parts for another customer. No one I know makes the parts you are asking about. When I have this situation I have to find a used tension unit for sale, like on eBay. They are in short supply right now due to everyone sewing masks on the old machines. When they come up for sale they usually sell within hours. I've had to set up notifications on eBay to notify me when a unit like that is available, that's how hard they can be to find. I've had a couple people tell me they bought this "universal" tension unit to be able to sew while waiting to buy a vintage unit. www.sewingpartsonline.com/tension-complete-singer-422403-455.aspx Please note that the seller states you may need to modify the tension pin by making it shorter. Sorry for this disappointing news, but here is a little bit of better news. Singer models 401A, 403A & 404 all use the same tension assembly, so if you do search for a used one be sure to search by the 403A and 404 models also. Not many people know that yet, although the word is getting out, and you maybe can spot a 403A or 404 unit for sale. Again sorry for the news, but I'm happy you found my video and at least know of a solution now. Good luck, and thanks for watching my channel.

This is such a good tutorial, I especially appreciate the part on zeroing out the tension. You mentioned your wife’s sewing machines. Are they vintage Singers? I am going to guess she has a 403 and a 338.

[@andytubesewing1953]

Thank you for noticing the "Zero-out" tension part. I get between 300 to 500 comments/emails per month, and it is surprising how many are about tension. My wife's daily machine is Coco, the 301A I restored. She took that to replace the Palomino 301A she had for many years. Her other machine is a 403A (good guess) that she occasionally uses for buttonholes and blind-hemming. Bonnie Jean, the 338 I restored was given to my daughter upon completion. I had told her I would restore any vintage SInger she wanted and the 338 was it. Part of the reason was that teal/turquoise is a favorite color, haha. My young granddaughter may want a 337, she's not sure yet. I asked my grandson and he wants a motorcycle instead, hahaha.

Are you still working on your 411G? (It helps me know as I have many questions to answer per day) It's great that it works properly. If you are talking about your 411G then maybe the parts are slightly different. The Slant Needle machines made in Germany have a few different parts than the USA-made models. Sometimes there can be lint and dust built up on the parts that prevent full movement.

My Singer 401A would never click as I pulled the check spring up and I was having tension issues on knits and had tried every other issue, needle, thread, etc. So, I have completely cleaned and reinstalled my Tension assembly just as you showed us. It still will not click, so I assume my tension assy is not adjusting as I change the tension and since it is not clicking, I assume something is bad....maybe the spring or the bar running inside the assy. Everything looked good after cleaning it up. What needs replacing?

[@andytubesewing1953]

Hi, Kathy. Your assumption about the clicking may be wrong. The click is simply the check spring/take-up spring coming back down to rest on the "stop" (little point thing it rests on) after lifting it with the thread. It might just be how you handle the thread that you're not getting the click. Let's go back to what started your journey here; "tension issues on knits". A few possible reasons for that. You caught me at the right time tonight. I have about 1 hour before I need to leave for an appointment. If you'd like to email me and describe the tension issue more clearly and what is happening I can try to work with you. [e-mail]

[@kathyharris1755]

So sorry I didn't see your reply until now. I was assuming it was an issue with the assy since I did not get the click and I had tried everything else. With jersey, knit, spandex, etc I was getting skipped stitches or none at all, but on thicker material like cotton, it sewed great. It did not matter how I adjusted the tension, so I assumed it must be the tension assy out of whack. Background: I found this machine in a junk shop for $40. I had looked everywhere for a 401A. This was the machine I learned to sew on as a kid and I wanted the same machine. It was filthy and did not work. I ordered missing parts, cleaned it inside and out. Oiled it, etc and it was still sluggish and almost locked up. I let it sit for a year and I just pulled it back out last week and it works. It wasn't great, but more freed up. I kept cleaning and working and it is running really well. Then, I started smelling something hot and it was the pedal. So, I just rebuilt the foot pedal and found 6 of the carbon disks shattered. I cleaned and put it back together and it works, but I went ahead and ordered a new one without the carbon disks while I could get one. The hot smell concerned me. I have another issue besides skipped stitches...the thread sometimes frays from the needle up to the tension assy and breaking occasionally. Maybe this is related. Or maybe I have a burr somewhere? If I can get this tension issue and the thread fraying fixed, this may be the last issues and I'll have this battle won on my 401A. Note: the thread fraying and skipped stitches only happens on jersey, knit, etc. Any ideas and help are so appreciated. Thankyou. I wish I had found your videos last year. That would have helped me so much. You are awesome. So easy to understand and follow. Thanks again.

[@andytubesewing1953]

@@kathyharris1755 If the thread frays only on knit I'd say it is not a burr on the take-up lever or the thread guides, otherwise it would fray all the time? The 401 and 500 class machines have a know problem sewing knits, especially double-knit fabrics. Singer found a solution by adjusting the hook closer to the needle... very close like barely touching. The adjustment is in the Service Manual and Bill Holman wrote a paper about how he and other repairmen would make the adjustment. I can share those documents if you email me at the address I listed in the previous reply. Also, sometimes, but not always, threading the needle a slightly;y different way can fix the skipping without making the involved hook adjustment. YOu run the thread behind, not through, one of the thread guides. I demonstrate that method starting at 9:05 in this video: kzbin.info/www/bejne/o2icn6WVea2FrbM If you want the documents tonite I suggest you email in the next 7 minutes as I am leaving.

Andy, I've been trying to trouble shoot the problem with my Singer 401A which I inherited from my Mom 15 years ago. This is the first time I've had any issues. The machine just stopped stitching from one day to the next. After watching a number of your videos it seems to me I should replace the Tension Unit and the Finger and Hook. Do you agree?

[@andytubesewing1953]

Since you only said "stopped stitching" I would advise against changing out any parts yet. Especially when it happened from one day to the next. The hook on a 401A is very strong and it is rare to have to replace it. Maybe polish out a burr from a needle strike, but not replace it. The tension unit is all metal and seldom wears out to the point of causing a machine to stop making lock stitches. It could definitely need a good cleaning/de-linting. The needle bar could have been forced up and that would cause a loss of timing. To be honest, when something changes that drastically from one day to the next I've found it is often user error. It could be you wound a bobbin that is the wrong type, like a class 15 (flat sides) vs a class 66 (curved sides). You missed something along the needle threading path or the needle thread did not go between two of the tension discs. Lint can foul the tension discs from coming together to provide tension. The needle was installed wrong, the thread to big for the needle, the needle was not installed 100% up into the needle clamp. Just to name some of the possibilities. A better description of exactly what is happening, or better yet pictures or video posted to your KZbin Channel or the cloud that we could see may help us diagnose better. There are other things I could suggest, but not knowing how the problem is presenting makes me hesitate and send you down a rabbit hole. Please be cautious about replacing parts at this time.

Wonder if you could help me? I have a Singer 401G -similar but slightly different to this machine. The tension unit seems to be identical to this but ... I put a new tension spring on it a little while ago (I managed to snap the old one) and ever since I have kept having problems with the top thread randomly sticking in the tensioner. I have taken it apart again following this and your other video to see if I can improve things. (I now suspect it might be due to the replacement spring being slightly different -but I no longer have the original one to check). However the tension stud does seem slightly bent, but my main concern is that I can't remove it from the machine. I have completely removed the screw at the side, it rotates freely but I just can't get it to pull out. Not sure if it is because the 401G is a slightly different design or if it got bashed at some point which has wedged it in there. And I can't decide if I need to force it out or not bother - the inside pin does move. Any advice appreciated

[@andytubesewing1953]

First I'll say I've never even seen a 401G let alone worked on one. I've never been able to find any Parts Lists for the German-made Singer machines. In pictures, the 401G & 401A Tension Assemblies do look the same. The 401A check spring part number is 66774: www.vintagesingerparts.com/products/upper-thread-tension-take-up-check-spring-part-66774 Are you sure you need to remove the Tension Stud? Is it just the slotted ends that are bent? I've repaired a few of those on and off the machine if they were not too bad: kzbin.info/www/bejne/f6LSiaegYpmnfLM I have had a couple of tension studs act like yours where I could twist but not pull. I eventually got them out by twisting and pulling at the same time. I believe the cause was the mounting screw had been over-tightened and left a "spur" pushing up from the screw indentation on the stud. That somehow blocked the stud from pulling out. Once I did get them out I was able to file the spur off with an ememory board and the stud was easy to install/remove. The tolerance of the hole to stud diameter is very close for sure. You can also go inside the nose and remove the Tension Releasing Pin Lever and use a brass flat punch to tap on the back end of the stud, but you must be very careful. That way is a lot of work so I tried just the twist/pull method and it worked. You don't mention where the needle thread is getting stuck on the tension system. If the assembly has 3 tension discs as in the 401A, try threading between the 2 discs closest to the front. That can make a small difference if the spring is a tiny bit long. BTW, I've never heard of the tension spring getting "snapped" so congratulations on that adventure!

[@whydontyougetlost]

@@andytubesewing1953 Thank you so much for your reply and help. I'm in the UK so I believe the German machines are more common here. I have given up trying to get the tension stud out - I have tried pulling and twisting etc but it isn't for moving - I think it well could be the mounting screw being over tightened as that was difficult to get it out...if I ever need to take the tension release lifting etc mechanism out of the nose I might try to get it out from the back then but for now as long as just trying to straighten it works I think better not to potentially create more problems. Snapping the spring - a real fluke accident, all really fast and not sure exactly how it happened. I was sewing a large and heavy canvas material with strong thread, accidentally hadn't cut one of the threads properly. I was stood up and a bit away from the machine as I pulled the material out I nearly pulled the machine off the table .. I grabbed at the machine, caught it , dropped it and grabbed again - luckily saving it. - all the while still holding the canvas... I didn't realise the spring had snapped until I went to change the thread...and honestly I was thankful that was the worse thing that had happened, it could have been so much worse. Especially as it was my Grandma's machine, she'd looked after it all those years and I'd only had a year or so .... Thank you again for your help - and your videos - I have only just discovered them but know they will be really useful for me going forward, helping keeping my 401 going - hopefully to pass onto my future grandchildren.

[@jacquelynconant3926]

Hi I have a 401a which I've been using for past year just fine. The the other day while I was sewing it stopped stitching....the thread from top just lays on fabric and bottom pulls loops through fabric. I've messed with tension going up and down.. nothing is helping. What do I do?

[@andytubesewing1953]

Well, it is obviously a tension imbalance. If the top (needle) thread is flat that means there is more tension on it than the bobbin thread. What did you do just before this happened? Had you put in a new bobbin of thread? Your top tension may be fine and you may have lost bobbin thread tension on the bobbin case. It has a tension spring also (on the side) that you pull the bobbin thread thru. Have you looked at the bobbin case and hook/feed dog area? Have you cleaned out all the lint there? Does whatever you are sewing create a lot of lint or fuzz? Lint/debris can get pulled beneath the bobbin case tension spring. It can pile up thicker than your thread. Then the bobbin case spring can't push on the bobbin thread to create tension. No bobbin thread tension means the needle thread tension will be stronger and pull the bobbin thread up thru the fabric no matter the upper tension setting. Rarely the tension spring adjustment screw can vibrate loose or even pop out of the bobbin case creating a zero tension situation. It's easy to test your upper tension. Remove the needle thread back to the spool and rethread it up to but NOT THROUGH the eye of the needle. Lower the presser foot, set the tension dial at 4, and just pull on the thread anywhere after the tension unit, maybe near the take-up lever. You should have some tension on the thread but be able to pull it off the spool. While pulling the thread then start turning up the tension dial, like 5 - 6 - 7 - 8 and you should feel more and more tension on the thread. When you find that is OK then you need to look closely at the bobbin case.
