Sewing Machine Motor Repair.

Fixing and cleaning brushes in sewing machine motor After running for awhile the brushes seated better and sparked Less Also a small amount of Sparks are normal same as in a drill Etc . It should not be more than what it looked like when I was done

[@mamasaidsew4843]

Thanks to this video I was confident enough to take apart my Brother sewing machine motor and replace the brushes. It works fine again. Thanks so much!

[@not2fast4u2c]

You are very Welcome ....Thanks for watching !!!

[@scramm415]

Thanks for sharing your knowledge. My husband has his truck and I have my sewing machines.

[@not2fast4u2c]

I am glar this video has helped others to work on these little motors

[@GRMS_Ian]

Hi, nice vid, I have a tip you may like. Sorry a bit late .. To correctly bed the brush on the copper commutator, wrap your 400 grit paper around the copper then push the brush on while you rotate the rotor, this way you will get the exact curvature required. Take care ...

[@LynnStone]

I love your style. That was a big help. I am amused that the person above watched your whole video if they didnt think it was helpful. If it is not for you one would think one would figure that out more quickly! It great for me. Thanks.

[@HewyDewyLewy]

Great tutorial. I've added this as a part of my library.

[@melpennock9113]

Fantastic video, you gave me the confidence to attempt to fix my overlocker motor, and it worked, your my new hero xx

[@not2fast4u2c]

Thanks for watching.. These motors are tough But they get over oiled and cleaning everything usually fixes the brushes from sparking too much

[@donnahollingsworth5270]

Thank you for posting this video. I have an old 348 that needs a new motor. The original motor smells "hot" when I run it for more than a minute. I am going to try to open it up and follow your directions. Couldn't hurt anything!

[@not2fast4u2c]

***** Thanks for watching !!!

[@SuperModerngranny]

Thank you so much for this video! I have now cleaned and oiled my sewing machine motor, although it's not the same as yours, just slightly different. :)

[@Lark993]

thanks for the help, all these years later. cleaned up my singer 206k motor, was making awful noise and smell. rotor is worn smooth on one side.. but it works.

[@not2fast4u2c]

Glad it helped

[@DKMeng]

thanks for making this video and having it on youtube. i would have kept on using the machine with the motor running very slow or might have bought a new motor.

[@not2fast4u2c]

Meng EFresh You are Welcome I have found motors cheap as $25 but it is nice to have the original one Thanks for Watching !!!

[@SkyJamVideos]

This is excellent, great tutorial

[@CYNWORLD]

Thank you for this information. I have an old sewing machine with broken wires. I was wondering if i should open the motor and replace wires or buy another motor.

[@wayneo7307]

The Pencil Eraser Reminds me , We Used to Use them on the Armatures and Pickups on Aurora HO Slot Cars in the 60s and 70s ! Anyways Great Video !

[@not2fast4u2c]

My brother and me did the same thing !....We also used are Dad's mennen skinbracer after shave to clean out the motors and the we would stick the sled runner things directly on to the transformer box and wind them out to full speed ..We had a drag strip that we set up and it was measured to scale of a real 1/4 mile ..We would soak the spongy slicks in after shave and do burn outs and make the tires sticky

[@tedkelly4663]

We have smoke coming out of our vintage Brother motor (over 40 years old) I stripped it down after watching your informative video cleaned the commutator and filed the brushes, it was a little dirty inside but thought i'd cleaned most of carbon residue off, maybe this old machine is ready for the breakers yard. (Brother has confirmed that replacement motor is not available)

[@hh0520]

Thank you for this tutorial! It really helped. Could you possibly show how to change the outlet cord for this type of motor.

[@not2fast4u2c]

Yes the finer the better I also use scotch brite pads Like those kitchen scrub pads on copper works good on small motors a pencil eraser works good

[@woolandwaterknits4801]

This is a great video - thank you! I have cleaned a lot of vintage singer motors/machines. I have a vintage 830 Record Bernina. When I step on the pedal and hold it full speed the motor runs fine then winds down, runs and winds down. It sound like I am lifting off the pedal in even intervals, but I am holding the pedal down the whole time. I am thinking/hoping all I need to do is clean the motor and put in new brushes. I HOPE it's not the pedal b/c I have never fixed a pedal before! (:

[@not2fast4u2c]

Glad it helped ..Thanks for Watching !!!

[@bethblood9124]

I enjoyed your video and it was helpful. I have one problem and that is there seems to be no available videos on how to connect the light and motor and foot pedal together in the right order. If you understand how to do this it would be an extrememly helpful video.Thanks Beth

[@emmah6045]

I fixed (rewired) a Singer motor yesterday--found a diagram on google images. It was a black and white image, so I printed it out and colored each wire from starting place to destination. It helped. Works fine.

[@not2fast4u2c]

I am glad you liked watching there are some good projects you can make with these Glad I did not waste 14 minutes of your Time That was funny !!!

[@annareuter7639]

Good Video. Oil cannot dissolve into "bronze (brass?)" fitting. Chemically impossible! My theory: Oil seeps around edges of the fitting. Note the hole for oil on both sides of the motor. My motor has the same two holes and my brass fitting stops short of the end of case.

[@simplyconnected]

You are wise not to use an abrasive on the commutator segments. That black you see in the copper is conductive graphite, formed from the brushes. If you take the commutator down to shiny copper, the brushes will need to reform that film again. That wears the brush down. Use a pick to scrape between the commutator segments. They are micarta and if they are allowed to stick up higher than the copper, the micarta will lift the brush, then arcing will persist. So, clean between those segments.

[@not2fast4u2c]

If I was re building a bigger motor like a car starter ..I would use a lathe and turn down the copper ..I would also be using new brushes that do wear down a bit as they break in ..I also would use a piece of a coping saw blade to re cut the slots between the segments

[@annareuter7639]

My apologies. I was wrong! There are oil-infused Bronze bushings with SAE oil. Oilite is one brand name. Antique sewing machines in the 1930s had a oil/grease reservoirs. Bronze oil-infused bushing was developed in the 1930s. My 70 year old machine (like yours) has two similar bronze bushings (each end). Luckily for me, the tangs of the 2 brackets are still holding. My westinghouse motor (circa 1950) has 2 oil holes just on top of the case dimples. Manual says to add a drop of oil into the 2 holes yearly.

[@not2fast4u2c]

That is why I did not respond to your other comment ...I have a piece of the bronze that I made a bushing for my 40's lathe

[@annareuter7639]

@@not2fast4u2c I am a chemist and the general principle is "like dissolves like." Oil as a liquid cannot "dissolve into" bronze, a solid metal alloy (mixture of metals). Likely there are nano pores throughout the bronze that are "infused" with oil. Example: Oil does not dissolve in water. An emulsifying agent will disperse the oil throughout the water. I am nitpicking, admittedly. I am also struggling with the refurb of my Mother's old sewing machine motor and your video was very helpful.

[@not2fast4u2c]

@@annareuter7639 They make bushings from bronze that are small little pieces pressed together which leaves space for the oil to soak in I think they are called sintered ? bronze

[@IsaiahSleziak]

To avoid the tape issue, just stick a piece of paper on the the tape where it contacts the brushes

[@not2fast4u2c]

+Isaiah Sleziak OK

You are Welcome thanks for watching !!!

[@not2fast4u2c]

THANKS !!!

[@elizabethlavender8294]

thanks great video...would this type of sparking in the motor cause the breaker to trip?

[@not2fast4u2c]

The new ground fault circuit interrupters could trip from a motor sparking

[@3circles]

Thanks so much for this!

[@not2fast4u2c]

Glad I could help..Thanks for Watching

You are welcome

[@eunicetimbrook54]

I and working on a Montgomery Ward sewing machine motor...and the motor outlet shell, the side with the cord, is stuck can't seem to get it off. Afraid to break something...is there a way to remove it safely?

[@not2fast4u2c]

You should be able to put a new cord on it It can't hurt to open it and see how it is wired

[@michellemiller4313]

Hi there. Great video!! I just took my mom's 1963 Kenmore motor apart thanks to you! Looks like the washers on both ends of the shaft are bad. How many are usually on each end? Where do i get new ones?

[@not2fast4u2c]

I would not know where you can get washers ...If I added any I would make sure it is ...centered on the brushes ..and the motor spins free when assembled

[@Sun5787]

I watched your video before and I now review it again. I just bought a old vintage sewing machine that I'm cleaning but the motor come and goes and spark alot, any suggestions? I haven't open it yet.

[@not2fast4u2c]

I would take it apart and clean it like I did

[@joseavenreybarrientos1972]

it is ok to replace higher R.M.P to original R.M.P motor?.

[@krystleroy3068]

I have a serger and the motor has a weird metal smell and the it gets warm fast I’m hoping it’s the brushes

[@nigeldalebisram]

The shaft and motor isn't coming off from the sheath... Singer motor model hf 07150

[@lee-annkelly9464]

I installed thjs motor using my original bracket onto my pfaff 130. After only a few minutes of running it the motor and foot.pedal were very hot. Did i do something wrong?

[@not2fast4u2c]

I would not know..Are you sure your machine can use this small size motor

[@not2fast4u2c]

Thanks for watching

[@NoelaRybinski]

Hello, I know this video is filmed a long time ago but I hope you can reply. I have the same motor. I have opened it and cleaned everything. I have assembled it back together and that metal shaft that sticks out is moving back and forth, if I pull it by hand. I'm not sure if it used the happen before I didn't check. Just like in yours, there are no bearings, only this hole that I also had to tighten as it was wobbly. It also moves when the motor is on, so in order for the bushes to be in the correct position you have to push it slightly when it's on. Is that supposed to happen, is it the design? Maybe when I'll connect the belt, that will hold it in place? I would appreciate it, if you could help me. Thank you

[@not2fast4u2c]

maybe add a thin washer to keep the shaft were it should be

[@NoelaRybinski]

@@not2fast4u2c i just did that but wasn't sure if it's supposed to move or not. As there isn't anything in the design that would stop it from moving. I actually had to add 2 metal washers and the one that was already there for it to stop moving. Thank you for your reply

[@donnajohnson1465]

The screw to hold the motor in is so tight, I am afraid to break it loose. Any suggestions?

[@not2fast4u2c]

Donna Johnson You coul spray a little WD-40 on it I don't know if you could find another small bolt that long If it breaks at least you can get a motor for around $20 If you have a repair shop near you they may have a bolt I would try to get it loose by turning it back and forth a little at a time

[@learnwitharslan1049]

hy buddy my sewing machine giving me current sometimes....... what the soulution??? can you help me

[@smartstitch7136]

Dont touch it 😜😜

[@tahirm7177]

hi. i have a jones sewing machine and has very similar looking motors to the one shown in this video. my problem is that the machine won't stop running. what could be the issue. please help.

[@not2fast4u2c]

+tahir m Does it have the foot pedal ? it could be bad

[@Sun5787]

tahir m if you have a double plug, one that connect to the light and the other to the motor, switch them, you connected the foot pedal to the light instead of the motor. If you look closely at those old plug it's engraved on it. Motor and light.

[@renevanwyk4053]

In case someone reads this in the future, in my case every time this happened it was the capacitor in the control pedal. It seized and is closing the circuit. Cut out the capacitor and you're good to go.

[@talbensimhon]

How in the world do I get the tiny screw off the pulley so that I can remove that second casing and access the commutator and brushes. If i put a flashlight into the the holes I can see the brushes are worn down. I can't for the life of me get the pulley off to access it :( help please

[@not2fast4u2c]

If you have the correct screw driver that fits It should loosen the screw...The only other thing I could do is drill the screw out ..Which is not easy

[@talbensimhon]

not2fast4u2c the screwdriver is correct, flat and the right size. But its deep and won't budge and the head has been warped a bit by now. I thought of drilling it out but not that sure if I should

[@not2fast4u2c]

Can you buy a new pulley...and carefully cut the old one off .I used to have a sewing machine repair business near me ...but now I would have to try the internet

[@talbensimhon]

I could take it in to a shop but they'll automatically change the motor and charge me a lot for it. I think thats my only choice, not comfortable sawing thru the steel pulley, the rod may get damaged and finding the right pulley ay be an issue.

[@nileremsing3382]

can I change the motor cord on a vintage singer sewing machine Model 15, from 1942 , that's been sitting for years. I was able to change the cord to the foot pedal and to the lamp but don't know how to take it all apart. It is a motor # 1819146 simanco motor catalog P.G.7 100-110 volts 0.6 amps. The wheel goes around it doesn't seem seized up but the cord is rotten. And How do I get back to you to see if you answered me? I guess I'll write your name down. you can pull up my fb page maybe? or pm me. ?

[@not2fast4u2c]

Sorry but without having it in front of me ..I can not tell you how

[@not2fast4u2c]

most of the time they just need oil Never over oil like I did and get it on the brushes

[@not2fast4u2c]

Sorry I wasted your Time

[@moshe2002]

14 min wasted

[@nomecognome8416]

"motor repair" ? Clean the motor!!!
