I have had the same 280L for over 20 years and just finished the modification to slow it down. Its way better!!!! I went with the 2 inch pully and used a 42 inch belt. The belt barely fit a 41 inch would have been better. Only wish I had done this 20 years ago.
Thanks for a great video.

I did not yet change the pully on my Artisan 5800 which my tech calls a racehorse. I instead lengthened
the 12-inch clutch actuator bar by adding a 12" extension bar and bolting to the original making the whole thing
2 foot long and then I had to move the connector to the left side of the foot pedal from the right side.
This made the pedal travel, greater but it fine-tuned the pedal action making foot motions easy to
engage the clutch SLOWLY and evenly. I'm still going to change the pully too.
I'm so glad i found this video! I inherited an industrial singer machine that I am not familiar with. I was told by the service guy that i might con sider replacing the clutch motor with a servpro motor to lower the speed. I learned something new, thanks!
Thanks so much for your video!!! I changed the pulley on my 206RB3 to a 2" , cut the existing belt to fit and found a suitalble replacement , an oregon 75-442. Since I changed out the table top and am finishing up I haven't had a chance to use it but there is a very noticable speed reduction ... can't wait to put it into action, thanks again .
We recently bought a Yamata. Almost identical to the Juki. Craigslist special. Fast as hell. Has a 2" (approx) pulley on the motor and a 4-5 inch on the machine itself. Another YT vid showed replacing the machine pulley so that's what we did. Works like a champ. 51 inch V belt. If I could also put a smaller pulley on the motor I would. Thanks for the vid.
Good video! Thanks for the metric numbers, for us imperially challenged people 😉
Thanks for the video
HA WES, i think forgot to say thanks very much for the great on the job training . well thats what its like to me i just turned 65 and retierd and bord to tears alllllll most.then dug out this singer 4432 heavy duty that i got for patching stuff but never did much with it untill about a month ago , and well i got the BUG, the sewing BUG im going for it im ordering a singer profinish seger and i cnt wait i have bee watching all of your videos and im just sucking like a spong. i had all the bobon problems and the bird nests etc. but smooooth sailing now and im CHOMPING THE BIT fir more so im a apprentice second class for now but ,i want to know MORE, so thanks very much and you have a good bed side maner a thay say...............
4L = belt width and pitch angle of the v groove), 460 = length in inches of belt (46 inches). Example, 3L460 belt is the same as a 4L460 except for belt width. Pulley groove width and pitch is an engineering thing, and there are charts that cover their use and it is complicated. Just be sure the belt matches the pulley for good belt life.
Awesome 👌 it helps
Juki states in the manuals what type and size of belt you should use with a standard 400W or 550W clutch motor. I've replaced my clutch motor with a servo on my industrial serger and had to by a smaller belt size only because the position and design of the new motor required so. I suppose industrial sewing machine belts and pulleys, disegarding the pulley sizes and belts length, are the same all around the world.
Thank you Sir❤
My Consew 2230 has an M42 belt on it. Clutch motor still going strong, but I know sooner or later I'll probably get a servo.
Love the ad, your funny
I have that same 280L for almost 30 years. Great solid machine! You should do a video on changing out the old motor for a servo motor. You can then slow it right down to a crawl.
Hey Bruce. Just wondering what servo motor did you put on your machine. Looking to do the same with mine. Tried the pulleys but it is still too fast because of the clutch; it grabs to quick for individual stitching.
One thing to keep in mind is the oil pump is driven off the main shaft and is designed distribute oil at the higher rpms when it is needed most. You might starve your machine if it only runs at crawl speed,
@@irabowers9057 I still did not put the servo on it.
looks just like my juki,, tried a pully but still had trouble controling speed so went with a servo and that is a dream,,and can change the base high end speed as I get better or want more speed..
It's the same machine as your Juki. Nakajima made them for Juki.
One of my questions was going to be about servo motors and small pulleys. I'll go see if you made that video. Also, what would changing to a smaller pulley do if a person had a needle position synchronizer on their machine?
I guess it makes sense that you would need a smaller belt for the smaller pulleys. I probably wouldn't want the machine slowed down. you should try servo motors. some servos have a speed adjustment lever so you wouldn't even need to change out the pulley. they're also silent
Servo motor 130 bucks. New pulley, 12.
You could save a bunch on electricity and get on the fly adjustability by swapping that always-on clutch motor with a variable speed DC brushless motor.
yes on servo motors please.
Wow!! Amazing video!!! Could I put a smaller pulley on a servo motor? Thank you
Your videos are super great. I would love to apprentice specifically on industrial sewing machine. What's it going to cost me?
Is there a way to slow dow a Singer Heavy Duty 2243? Love the channel by the way.
For a real budget job ok, although Servo motors are so cheap these days just swap it over.
I have a singer 188k-1 without a belt . How do you maintain the motor and what kind of belt do you place on this machine. Thankyou.
My Singer HD 4423 is really strong but also very fast! Sometimes its a pain to tame. Do you have any idea to slow it down? 🤗
No need to ever change pulleys or belts on a servo motor, just turning the speed dial on the servo motor does everything you need. Servo motors are only around $100 these days and you will wonder why you didn't switch sooner!!!
Where do you buy ur parts for a nakajima 280l. I have a broke thread lever arm
I put a 4x4 and 2x4 stacked so pedal don't go anyone think of a problem doing it that way
Hi!.....am wondering why you didn't mention putting a bigger pulley on the machine itself?....thoughts?
Mercury M-145-H has a 3L 420 pully
Thanks so much for making this video! Really useful. One quick question, my machine shaft is 25/64 in (1cm) and can't seem to find any pulleys that fit :( Any suggestions? thanks!!
try converting to mm, 10mm will fit
Now, how to decrease the speed and, more importantly, increase the torque on a regular sewing machine?
Which rpm motor is that
Would you recommend slowing down internal oil pump lubricated machines?
That's an interesting question. Correct me if I am wrong, but you really want to know if decreasing the machine speed at the hand wheel will make the oil pump go too slow and not circulate sufficient oil to necessary parts? As regards this context of lowering speeds by changing pulleys, I don't think there would be any problems of "under" oiling. The circulation of the oil pump mechanism is proportional to the speed of the the connecting shaft in the machine - higher speed faster oil pumping, slower speed then slower pumping. Just remember that you need to be vigilant about any and all of the oiling points not covered by the internal oiling system. If you use your machine infrequently, it might be prudent to warm up the machine and get the oil flowing prior to sewing.
On a Juki that I have worked on, the oil pump is an impeller and won't actually pump oil up below a certain speed. When doing slow careful work with the servo motor, I don't see any oil flowing through the view port. To compensate, we periodically run the machine at high enough speed to see oil flowing in the viewing window. It doesn't have to. be super high speed to get good oil flow. I think even a small amount of oil is fine for slow speed sewing.
Sorry, I forgot to add this-I ordered a motor for this machine and replaced it but that wasn't the problem, still racing fast!
Singer Model 149Q. Thread is not. Picking the thread from bottom. Spool
Здравствуйте. Вы не подскажите где можно купить швейную машину BROTHER lt2-b838. Благодарю вас.
I didn't get a reply from a comment I put on your repair video of a Husqvarna Viking Designer SE! I have a Designer 1 and when I turn it on, needle starts going up and down furiously fast and no way to stop it, none of the buttons work or the touchscreen (IT WAS WORKING PERFECTLY UNTIL I SHIPPED IT AND WAS RETURNED TO ME) THE BUYER got the machine out of the box and said this was happening so he didn't want it, didn't know how to fix it) H E L P !!!
You will have much better luck contacting me via my website. Sounds like a bad board, they are very difficult to find.
@@SewingMachineRepairGuy Thank you. What is the full name of the board? Is this something you can assist me with??
@@SewingMachineRepairGuy new to fixing my own machines
Would change the belt and pully put drag on the motor? Aka do damage?
Newer Machined with embroidery.
Im just about to get a Mitsubishi ls 120 i think it is , anyway are you able to convert a machine like yours and mine to use a walking foot, there has to be a way, from what i can tell it seems to be a completely different machine just to have that option.
any idea where a larger pulley for on the sewing machine itself could be found?
