- This video walks though rebuilding a CrawlMaster sport motor. Topics include basic assembly, parts, troubleshooting, timing, reversing rotation, and additional motor operation concepts. Do not break in rebuildable motors in water!!! You will quickly ruin brushes and risk rusting your bearings! Do not use sandpaper on your commutator!!! What should you do instead? Watch the video to find out.
Motor rebuilding tools/ Basic (no lathe): #1 phillips screwdriver, 2mm allen (optional), .20 or .22 caliber brass barrel brush, pencil eraser, new brushes, soldering iron if brushes are soldered instead of bolted, 0w or 5w motor oil for bearings and 10w motor oil for bushings.
Advanced rebuilding tools: 3/16" nut driver (modified) or 4.5mm spring post wrench
hobby knife or fine blade, Comm Lathe and patience!

Probably the best brushed motor rebuilding video out there!
Thanks! We hope it is quality, as this is what we do for a living :D
I love the subtle comment "like the back of a CD...if any of you watching this are old enough to know what looks like". John is always entertaining!
Holy cow! My confusion about breaking procedure has been settled. There's so much half baked information out there about how to break in a motor, you don't know what's right and wrong. But this video laid all that to rest. Thank you
Im running a BL 2200kv stubby in my crawler and i must say im really impressed with the power and with a 10t pinion and 56t spur i got all the torque i need. Great motors. Was really surprised to hear at the end of the video that "do not break motors in in water", i've seen so many videos of the motors being broken in that way and was going to do it myself. Until now of course. Thanks, very informative video for a new to RC person.
Thanks for the video I just got threw installing my BR-XL ESC and from the test run I did not tuned dude crazy power for my wraith thanks for making a great product! And colemans video series sold me on getting this ESC and I'm glad I did 👍👍👍👍
Thanks it's been awhile I'm pulling out some old motors out from the 80s that need some attention great video.
I sent an email asking for help to Holmes Hobbies on what motor would be better for my rig and got the best explanation and answer, best customer support in the industry.
I do not even have any rebuild-able motors, but i still watched.. great how too video John!!!
Awesome...You guys build quality motors, cobalt puller 380, in a TF2 and I love it. Makes it act just like the 83 Toy. Excellent video, I bought a Orion motor tester and lathe to start rebuilding my brushed stuff. Thanks for the tips! Liked and subscribed!
where can i find a motor lathe?
I just picked up a lathe on Facebook garage sales and I'm going attempt restoring the drawer full of vintage modified motors I've collected over the years. I will be referring to your video regularly I'm sure haha
Great tutorial. Thanks John.
Incredible, nice work
I still have my old comm lathe, brings back old memories of trying to get a motor close tona team motor.
very well done helpful learned something new today!!!
Great video. Very helpful, thank you!
Great video John. Been using your product steady for three years with no issues. Keep up the great work. #inholmeswetrust
Just found your channel today man, very informative shows and to the point. Thank you.
Glad I can help!
Nice vid thanks
Love the comment about the CD👍🏻👍
This is 100% classic video. 👍🏼
Honestly, this is a really good tutorial video.
Glad it may help!
Hey Holmes, great video :o)
Just bought one of your motors. First one!
Subscribed!
thanks for the support!
Excellent,simple but informative video for us newbies....now where is that motor! Thank you.
Very helpful info. I used your 180 degree bell flip trick to turn my forward motor direction in my no name 45t motor. It did not have timing adjustability, however the fixed 2 bell mount holes in can let me turn exactly 180 degrees..amsome trick.
Yeah, , I learned so much 💯.
NOW , on this video,, care and maintenance,, That lathe .you have is. COOL,, I have to show dad THIS video. .
Take care now,, be safe as you can .. There,, 👍😎
Nice👍🏾
Haha cd's I remember having to lug those giant cd books that held all of your music and they would always get scratches so easily. I was super attentive as to how I would grab my cds out of the cd player and never touch the playing side
So wet sand the comm with what grit paper? =P
Nice vid John and thanks for letting us know integy still makes a lathe. No idea what happened to my old one.
the smile that he's trying to hide while saying not to sand down the commutator is priceless :)) ... it's like he knows we're all doing it :)) or maybe i'm the only one feeling guilty here
Great video! Do you have any experience of cleaning a Tamiya Super Stock TZ motor’s commutator with Tamiya cleaning brushes? The reason I ask is I can’t get them to work! I’m using the correct stand up cleaning brushes and only replacing the motor brush on one side (+ or -) but the motor won’t spin when I power it up. The motor works fine with both its brushes back in. What am I doing wrong?
When the commutator is eventually worn down all the way ... is it possible to attempt repair it? Maybe by gluing new copper segments over it?
Do you run capacitors on your brushed motors?
I've got one like in this video and one that is a cheaper Chinese 540 that does not disassemble. I'm using them in projects where brushless isn't precise enough.
Is it possible to take a good 550 Motor and replace the shaft with a longer shaft that extends from both ends?
Hi bud regarding brushed motors.
I have worn down one brush more than the other. Why is that?
Also laydown brushes give more rpm?
can this motor handle 3s with 16tooth pinon
DANGIT, I had to watch this video AFTER breaking it in with water
Just be sure to dry and relube. Not the end of the world, but not what we recommend either.
Hi John. Great videos. So I’m just getting into the scale crawler rc’s. I love your motors but money is tight starting up right now. I was thinking of getting a yeah racing hackmoto. Where can I get replacement brushes. And do you recommend a different motor in the $20 range. Looking for a 35T for my scx10 ll kit. Thanks for your time.
We have the TrailMaster Sport motors for $20 and under. The Hackmoto's are rebuildable, but I wouldn't spend the time or money rebuilding them. By the time the first set of brushes are wore out, the comm on those is typically wore out too because of how hard the brushes are. My sealed can motors have higher quality components, which is kinda sad!
Fantastic show 👍just one question,do you always used a spoke as your pointer ? Thank you for all that you do for all of us 🍻cheers.
6.5 Creedy I am also a wheelbuilder, so there are many spokes quite ready for the task!
HolmesHobbies I just thought it was kind of cool. I worked at a Honda/Yamaha dealer for 17yrs and went through a two sets of wheels on my yz400f so that's why I noticed the spike. Thanks again 👍
I thought it was better to break in the motor submerged in water, cause it keeps the com clean?
Great Tutorial John!
I know you don't get on here often, but I'm going to throw this out anyway....
A couple of people told me that my Wraith has a Clockwise rotation Motor. Is that true? As far as Timing is concerned, I guess I could just time it so it spins faster in forward, as you showed, by Sound...
I just want to know if that's true.
Carmine 🚂
I'm here all the time, but went on a trip down to the Ultimate Scale Truck Expo the last week. The regular wraith is reverse (clockwise) rotation. The Spawn I do believe was normal rotation. Just make sure it goes a little faster in forwards than reverse and you are good :D
John, how many times can a tater be cut before it becomes out of criteria?
Depends on how deep it is cut. We have minimum dimensions listed on our site, I think. They are also written down on our workbench, lol!
where can i find a motor lathe?
i installed a new silver brush set into a 13T torquemaster and they are way more noisy than the original copper brush set.?. did i do something wrong or miss an important step?
15:56 you mention the brushes clicking.. i think that is the noise that i hear. what is causing that and what is the solution ?
i also just ordered a used comm lathe on ebay and will receive it tomorrow. would cutting the comm on the lathe be the fix for this problem ?
Hi, Thanks for the really nice tutorial, I just got a new Hackmoto v2 form yeahracing, 35T. I think I ran it for like 3 min on 3v from my power supply, also, changed the timing a bit to get the minimum current on 3V which indicates that it is on neutral (I hope I did right), but still I feel that the motor is very hard to rotate on low voltage, it doesn't start like the motor in your video. When I apply 2v, 2.5v I just get high current draw, and unless I start it with my hand it doesn't rotate, does that sound right to you?. when I rotate it by hand (Unplugged) if can feel heavy resistance from the magnets. Also when running on 3v I can feel it a bit vibrating, and provide extremely low torque (I can stop it by just touch the pinion). Would love your comment on this.
Well, thats because it's only a crawler motor on the sticker and marketing fluff. They might say they are made for crawlers, but they are not tuned for them at all.
That explains why I burned my 540 hackmoto V2 35t today. The motor was barely used. It collecting dust for several years. I overheated it in 4-6 min on my stock gmade gs02f with unweighted steel wheels. It overheated worse than my goolrc 27t 540. I just order myself a crawlmaster sport 550 13t and a smaller pinion in case I need to gear down more than stock.
why don't these motors have fans on the shaft? Do they run cool without fans? Thanks
Our sealed can motors have internal fans. Our nicer rebuildable motors do not, as they run more efficiently and do not need fans when proper gearing is used.
Is there a way to clean off the comutater without a small metal lathe?
not really. a pencil eraser works if its really bad.
Hi . I own TQM 540 27t What is maximum voltage for it ? I'am going to use it HH water proof ESC .
Can you make rotor axle longer on back side ? [not comotator side ] .I would like to put little fan directly on axle . motor goes inside RC tank [ bad airflow inside ] .
,,,,TANK,,,,,,, you .
How about the issue of weak magnets ?
A motor can be rezapped if it's been overheated. Cheap weak magnets...
Not fixable
My brushed motor sometimes stops working entirely, I clean it and its back for a few days. Does this have anything to do with the brush wires touching the motor can ?
no, but the brushes may be hanging in the hoods or it may need a rebuild
What do I do if my commutator is too thin? I ran 2 set of brush on my torque expert and now it’s down to 7.16mm diameter
6.7mm is the low end, at which point a new armature is needed
Can you use your parts inside other motors? Say I wanted to use better magnets and a better internals in general to get better performance could that be done? Say a 12T Traxxas motor?
On rebuildable motors, yes. Not on sealed cans like the titan or my Sport motors.
at least, not easily. Would take about an hour of work and you would need to buy nice epoxy to transfer magnets. For $20 you can just buy a TrailMaster sport and have better quality than the titan and no work transferring parts.
Thanks for your advice. I appreciate it.
John, what the heck are you looking at during this video? 😉
I'm having an issue I would like your email to let you know what's going on. Thanks
🤘☕️🤘
Hi John, I have a Titan 550 21T motor can your break in method used on my motor or I need to break in the motor in water? Thank you
Yisrā'el Yaʿakov water will seat the brushes faster. You must blow out all water with air and relube bushings.
Thank you John for taking time to replies my question. Thank you so much :-)
Shoot I know what the back of an 8track looks like 😢
Oh the irony. I just watched this for the first time while breaking in a new Holmes Hobbies motor in water.
dry it out and relube the bearings then
@@HolmesHobbies Wow. I think that's the best customer service I've ever experienced. Thank you. I'll definitely be buying more motors from you in the future.
I rebuilt my non rebuildable motor
Can you clean the com. Without taking it apart? . How can you gage the extent of the weak mags?
You are so called unreadable motors bologna i re build them all the time
But you did not rewind .
You should always do this because you can slightly experiment with the add or subtract a turn here or there for customizing the torque vs. RPM
Situation personal prefe4nce.
Skewing armature poles is option also
