How To Change Your Vac Motor Brushes | Kleen-Rite


Hi, my name’s Tom, senior technician from
Kleen-Rite corporation. Today we’re going to
replace the brushes in a 6336 Lamb motor and a 9414 Lamb motor, the two most widely
used vac motors that we sell. We’re going to do the 6336 first. What you need is a screwdriver and a Phillips
screwdriver, standard size and a Phillips. Okay. The hold on clips on the top of the
casing. You’re going to pry them out. Pick up on the casing, one side at a time. Now it doesn’t come off easy. You got to get this clip back and pull up
at the same time. There it is. It’s off. Okay. Now take the Phillips screwdriver and take
out the two screws. There’s also a lead in this thing that comes
out. I found out it’s easier to take the lead
out after I’ve got the brush loose than it is to try and get my fingers in there because
they’re kind of fat. We’re going to take off the bracket first. Now, the brush will come up and come back
a little bit. Now if you look in there,
you’ll see a wire and what it is is it’s actually hooked onto a brass lead that goes inside. You take a screwdriver and push. The lead will come out. It comes out very hard, so
you’re going to have to be careful with it, because if you break this off, you’re going
to have to solder a piece back on or something
like that, something to hold it back on, either solder or crimp a new piece back on
it. The brush is out now. In the brush you’ll see a slot at the top. That’s where the lead goes back in. Now we’re
going to take a new brush. We’re going to line the lead up and insert
the lead back inside the brush and we’re going to push it
back in. There’s a pin on the bottom of the brush. Now you’re going to take the brush itself,
push it against the armature, put it down in, seat
the pin back inside. Once that’s in place,
take the clip, put the clip back on. Reinsert the Phillips screws. That brush is complete. Spin the motor 180 degrees. We’re going to do the exact same thing on
this side. Take the screws out. Other side, pop the brush out. Get to the lead. Wiggle and push. Brush is back out again. Reinsert the lead. Reinsert the brush. Put the hold on
bracket back down on. Okay. Reinstall the cap. Put the cap down in. Push. Hold on clip
should come back into place. You just installed new brushes on a 6336 Lamb
motor. Now we’re going to go to one that’s a little
bit more difficult. This should be a 9414. I’m going to remove the leads, which just
pull off so they’re out of the way. Reach
underneath the cover here, on the end where the brushes are. Pull out and up. Same
thing with the other side. There’s clips underneath here that’s holding
the cover on. Pain
in the butt. It’s off. Okay. Now you’re going to remove the hold on screws
on this one, too. All right. This one, actually the clip is right here,
which gives power to the brushes because it’s a metal outside. Pop the clip off. Just a matter of taking the new brush,
inserting in place, there’s a hold down pin on that too. After that’s done, we’re going to reinsert
this hold down clip. The clip actually goes over and claps that
down on top of the lead on that side. Reinsert the screws. Now I put the screw on the opposite side of
where the hold down clip is or the lead clip, because the clip holds it in place a little
bit. Spin it around, take the screws off the other
side. Pull the clip up. Take the brush out. Install the new brush. There’s also a
little clip on this one that lines up inside a holder on the bottom of this thing, too,
so make sure you have it in place, put the clip
back down. Reinsert the screws. Take the cap, line it up, push down. Snaps into place. Reinsert the leads. Now this is not
finished. What the manufacturer’s recommended is that
you run these motors at a lower voltage for approximately 30 minutes
to reseat the brushes that are in it. What
you’re going to do is you’re going to take one lead off each motor, doesn’t matter which
one, put them together with a wire nut. After you have these together with a wire
nut, you’re going to take the other two leads and hook them up to the 110 volt hot, 110
volt neutral. Start your backup or take a
power cord out there, whatever’s convenient for you. I prefer that you use the power
cord. Hook these two up, 110 volt. This is hot, this is neutral. Plug it in, let them run for
anywhere from 15 minutes to half an hour. Take them back off and then hook your
motors up the way you normally would inside your vacuum cleaner. That reseats the
brushes inside of it, actually puts a curvature on a brush that matches up to the
curvature on your armature. After that, you’re pretty well done.

  • Hello
    I have an electric motor just like this, but when I turn on, it starts to make sparks
    the engine begins to make sparks in this site
    can you help me ?

  • In some cases, when you install a brand new brush, it will sparks at first, just let it run for a while the brush will stop sparks. because it will takes some time to let the brush's shape that fit the Armature.

  • Great video. These motors look just like my Numatic George Wet Dry Vacuum 2 stage bypass motor. I had to look up what hot or neutral means: http://www.dummies.com/how-to/content/alternating-current-in-electronics-hot-neutral-and.html. Is it safe to stand a bare motor upright while it is running?  I can imagine it sucking the table and overheating 

  • On the 9414 motor, no need to completely remove the brush screws or the brass strap. Just loosen enough so the brush can come up and slide out.

  • May Eureka Sanitaire vacuum started blowing sparks out the exhaust end. Is this what it needs? I was told it couldn't be fixed by my vacuum cleaner repair guy. Honestly, he's never told me he could fix anything I took him. I think he'd rather just sell me a new one. I really like this little vacuum, it's got a bag I can empty vs buy disposable ones. I'm not a throw away kind of girl. Can I fix it? I'm pretty handy.

  • my vacuum cleaner removes a weird sound and u close ..bad smell comes out lime something is burning. ..pliz can u help and tell whts the problem coz it's only three months old

  • Hi, I have a 1952 Electrolux canister vacuum cleaner that I have been using for 25 years. I am pretty sure one of my commutator brushes bottomed out to the spring. Do you know how or where I can get new brushes? Thanks in advance.

  • Thanks for the video. I have never worked on a central vacuum system; knew nothing about them. After watching this I diagnosed that it was the carbon brushes on both motors, ordered 4 new ones, and replaced them within half an hour. Now it works beautifully! Super easy fix, and to think my husband wanted me to call a repair man to do it!

  • Hi there, I have a tough 15 vacuum cleaner that makes a huge noise sounds. What's the course of this noise and where can I buy the accessories from in SA please. I love this machine and it does wonders for me. Your help will be so much appreciated.

  • in mine the hold down shrews are cheaply replaced by stud en these are hammered open to hold down the Bruch housing so you have to get a complete motor. if this is the way to sell more well I will look elsewhere for a new vacuum cleaner. I am fed up wit non repairable goods.

  • Thanks for posting. I had one apart and was looking for best way to disconnect/reconnect the connection right at the brush. I thought it was a crimp/solder like some starters and alternators use. I was glad to see you just slide it off.
    BTW, somewhere in your recording equipment, you can turn down the volume a bit and get rid of that distortion. Thanks again for your help.

  • My Hoover S5673 Vac Motor sounded like a bag of marbles when tested. It tripped out when the Mrs. last turned it on. Took the vac canister down and watched this video. The plastic cap on top of this motor is retained in place by small hooks which are part of the cover (In my case). I broke 2 off (There are 4 on the cap). It is hard to judge the amount of clearance needed to free the plastic cover by using fingers to pull out the cover edges. The armature spun by hand but felt like a bad bearing was the fault–a little wobble. Then it locked up on me. I will remove the brushes next to see if one could have locked onto the armature plates. Bad brushes would be easy to buy vs a new motor. Without this video, it would have been difficult to start the job (Obviously) because the motor is inside the canister. It leaves no clue how you should dismantle it enough to examine the brushes without removing the whole motor. A job which should be easy since the brushes are in plain view at the top. Thanks so much!! The vac is 22 years old and has been faultless up to now.

  • So my neighbor had a problem with his gIII hoover. They went to local Vac-shop whom recommended a new one, but SUPRISE! special deal, we've go a used one for 900$, which they bought and had installed. As the one they had was identical to ours, of the same vintage I took it off their hands for parts. What was the problem with it? worn out brushes. Local appliance parts were no joy on finding new ones, but I found
    https://www.yelp.ca/biz/carbon-brushes-and-commutator-maintenance-products-calgary-2 and he had them in stock. 20 bucks and the sucker is now functional- and a nice guy to boot.
