[@Altema22]

Great video, and perfect for a person I know who's looking to do the same job. I've had hub motors apart dozens of times, but the axle and windings are about the only thing I haven't done yet. Most of my motors are Bafangs, and the magnet structure has slots that you can put the puller arms into. But I do it sideways in a bench mounted swivel vice so not to worry about the magnets dropping back into place. Thanks again for the video!

[@pcwriter]

Thanks dude! This gives me confidence to take my 500W Bafang rear hub motor apart to replace the cable harness that got shredded since the axle started twisting out of the frame a few months ago. Gonna put in a torque arm too so I hopefully don't have to do this again lol!

[@Anonymous-jm3mg]

A little dielectric grease will help that wire assembly slide in easier if you put a light coat on the sheathing. Try to keep it away from the end though, it'll make it tough to grab the end when you're pulling with pliers.

[@vibrationofmyfrequency]

Cool hard job done, so I decided to don’t do it my self. To complicated to change axis my self. Thanks You save me time

[@johnconway8254]

Something done did chew on those axle threads like it was a no.2 pencil. The cable in the axle how that got nasty maybe axle spin cant tell. I always reckoned the sun gear is stationary on the axle, maybe machined as one piece. And the planet disc assembly is attached to the rotor with the stator fixed stationary on the axle. So the planets would drive the ring as they orbit the sun gear. Your video here sure does clarify the real deal showing rotor and sun driving the planets on a stationary disc. The wiring to me is dizzying but I got 3 power and 5 hall on my connector that connect to that 'Lo Mein' inside. Yes, beware of the power of magnets, they will go where they want to in a hurry and won't stop if fingers are in the way. Thank you, great video brother! E-bike nut in the lower-48.

[@mickp10]

Thanks for showing the tear down and rebuild of the electric bike hub motor. Will help me when I have to do it for my face wise, as my hub motor doesn't spin when there's load on the bike, only when it's in the bike stand with the up motor.

[@TheHowtoDad]

sounds like your windings might have a short. if that's the case buy the same motor and replace the internals. it only takes 10 minutes to do that

[@michaelsanders9506]

The problem you had feeding the wire into the new axle. Next time take some 50 lb braided fishing line it's got the diameter of about 12 lb test strength and small diameter. Tie the braided line to the wires harness feed the fishing line through. Before you put the axle in. Then once it's in the braided line will help you pull the wire through. That's all I've done it and works good also you can take something basic like butter from your refrigerator put it around that harness it'll help it feed it through through with ease. Interesting pointing out that hole it's supposed to take Grease. That was frustrating how to take it apart again. Anyway great video

[@mikevecchio6284]

I pick up an e-bike for 50 bucks at a garage sale because the guy overloaded the motor and from my understand I either have to replace it or get into find out what's going on. This tutorial was a great understanding on how the system works. Good job and thanks!

[@TheHowtoDad]

best thing to do is to find the same motor, just the motor and swap out the internals. most motors are pretty cheap, I wouldn't expect to spend.more than a couple hundred bucks and about half hour of your time

Thank you this video come in handy replacing the cable and hall sensors in my motor 👍

[@E-BikingAdventures]

There's no commutator on a brushless motor. That's what the hall sensors are for. The rotor is the outer part with the magnets. Hub motors, like ceiling fans, and ebike motors have the rotor on the outside and the stator with the windings in the center.

[@TheHowtoDad]

awesome! thanks for that explanation

[@andrewstephens2687]

For clarification not all ebike motors are like this, (most) geared hubs are, but direct drive are not. The technical term is "outrunner" vs "inrunner" motor.

[@Jbmc65]

Where I case I ever need a hall sensor, where would one find those? Plus I just bought another e-bike like the one my wife has, when I was pushing it in the shed the back wheel was a bit tight, not real bad, it could be the disk brake or if it is in the hub what could it be? It hasn’t been used for about 4 years, it’s been inside the whole time. It actually has a lot less miles than my wife’s,, it’s an Emmo monster. They are good bikes, only paid $300 for it. Very good shape other than battery’s and that stiffness

[@shiloguthmiller1610]

My e bike started acting goofy. Just pedaling freewheel works and change stays on. The second I give some power it’s like the freewheel portion of it locks up. Kicks the chain off. I was thinking a loose magnet but not certain. Any ideas? I had just put new meat on it. When I first turned the wheel there was a clicking sound but couldn’t tell if it was that or brakes.

You seem to be the most knowledgeable one I've seen for e bike motors. I'm such a newbie but is there a way of testing to see if the wheel will move by bypassing the throttle and the module? By accessing the three main wires and the battery?

[@TheHowtoDad]

I would definitely not do that! the throttle sends a signal to the controller, then the controller sends the correct power to the motor. if you bypass the throttle and the controller your motor will probably spin up very fast, then never spin again

[@tommyhajimoto6968]

@@TheHowtoDad ok, thanks for the response. Hopefully you can shed some light on what's going on with my e bike. It's a front hub assist Jauopay eBay with 48 volt battery. I noticed my front wheel was loose so I tightened it but I think I over tightened the nuts on the motor wheel. It worked for a second and then stopped working and all I get is a click from the wheel. My dvom shows 57 v from the battery using pins in the wire, when I snap the throttle no drop in volts or break in connection from the dvom. Am I reading voltage from the module to the three wires? My throttle seems to be getting 4.5 volts but I get no voltage to the bigger three wires to the hub motor with throttle wide open. I did the simple test of touching the wires not connected and got a drag and resistance with no drag, I don't know what I'm looking for but I'm fairly good with the dvom. Hope you can help.

[@TheHowtoDad]

@@tommyhajimoto6968 start with the easiest problems first. Check all your connections. Unplug and plug them all back in, use silicone grease on each connection. Check that the pins in the plugs are where they should be. next step would be to check the throttle, may need to be replaced. it could also be your controller. if your controller overheats it will stop working and will need to be replaced. It may not be your motor at all, it is likely something more simple

Where did you buy the wire

[@TheHowtoDad]

I contacted the manufacturer directly. It was not easy to convince them to sell me the parts, and the parts were not that much cheaper than just buying a whole new motor. I'd suggest buying a new motor and just swapping the internals. it is MUCH easier, and doesn't cost that much more.

[@marknance1871]

hey for pulling wires through conduit you can use a lubricant (25-75 soap and water mix) to make the wire pulling process easier. i wounder if that would work for this application.

[@justinbeynon7980]

Where are the wheel bearings? At 0:49 it looks like the wheel bearings are part of the motor's plate cover? Is that so? How do you get at those in order to clean and regrease them?

[@jonasmeier417]

Great in terms of sustainability, but how long did it take in real time (also delivery time) and how much did the spare parts cost. It might be easier to order a 2nd wheel with motor right away.

[@utubeape]

That was an informative breakdown of the problems with a hub motor, and has helped me with something. I am going to replace my 500w rear with a 750, then I will have a spare 500w motor for my fat tire bike. I wonder if its possible to modify the shaft to make it fit the smaller front fork drop outs then add it to the front wheel and use the same old controller, another thumb throttle and a new small battery on a rack on the front, just to give me a bit of extra power on a hill when required. So now I know its kind of possible for me to add a new axle shaft. (I was planning to remove the cassette holder cut the axle down and cut new threads with a tap and die set.) what do you think?

[@TheHowtoDad]

anything is possible, if you do figure out how to mount it to your fork jsut make sure you use a torque arm

you should be able to do it, but you will need a pair of circlip pliers

[@organicintelligence6431]

I recently shredded through my green wire on the motor , I think i will replace the small section but it has been giving me an error 24 code. it would be cool to replace the plastic gears with metal ones , i wonder what pros and cons that would have.

[@Hellya38]

those planetary gears look like plastic made (10:36), would those teeth wear out quick?

[@TheHowtoDad]

they are some type of plastic. no unusual amount or wear. metal gears may be more durable, but probably give a less comfortable ride.

[@JCisJD]

Excellent video. Shim issues. Interesting I've had had the motor out to regrease and clean the gears, it all turns fine until I tighten it up. It's if it's catching, I thought I was missing a shim on the in side of the hub casing where you accidentally put one. Have you any suggestions why it might not be turning when I tighten back up . If I rest the motor back in lined up with the gogs, it drops in fine . It turns in one direction but not the other and when I put the screws in it doesn't turn at all.

[@petersenbass]

How long is that axle shaft? It looks just like the one on my Ancheer. I need to do the same repair but can't find an axle and Ancheer isn't responding. Thanks. great video.

[@NewSpirits]

Knowing me I would have just rethreaded the shaft for a slightly smaller size nut with a thread die?

[@TheHowtoDad]

I did try that. didn't quite work..would have required a lathe to machine the diameter, then die to thread. The moral of the story is: install a torque arm.

[@rickc2222]

Great vid, excellent shots and explaingin all along. super helpful...suggestion: some silicone oil or synthetic grease applied to the cable and shaft before inserting it likely would have made the job a lot easier getting that wire in. using pliers like yoiu did could damage the wires and reduce the current carrying ability.

[@Chris-bn1bn]

What are you thinking dude? Leaving the winding even nicked, can reduce the flow of current! All windings have a varying amount of insulation. Yeah, it's thin, but it's there. You can't assume to suck current through one wire into the adjacent wire. One strand will screw up the whole magnetic field. I would considder rewinding it with a slightly thicker, well insolated(dark purple/red). This will most likely increase your lost torque, and then some. Ask someone with hands on experience.

@@TheHowtoDad I contacted the manufacturer and they told me they don't sell the axel separate they only sell the core motor which is $299.I swear the axel you have is the exact same one as mine.

[@TheHowtoDad]

@@khanhknapp the axel cost me $100 and you can see how.much trouble it was to swap it out. for $200 more you can swap the internals, and be done with it.

[@ninasnider8167]

What manufacture makes the motor for your bike i have the same motor and cant figure it out.

[@khanhknapp]

Your video is awesome I use it as reference for me taking apart my hub motor to replace the axel just like you but I'm stuck and need some advise .The part I'm at is something you called a "Sur" clip not sure if that's the correct name but what's the name of the tool you used to take it off and how can I remove the "sur" clip if I don't have that tool?

[@TheHowtoDad]

ahh! good question, it's a circlip. you need circlip pliers. available at any car parts shop or online

[@mikeinmon4997]

Thanks

[@mikeinmon4997]

I need to replace the wire harness in your first step. I have to pull off the cassette correct? How did you do that with the wire coming out I can’t seem to find a cassette puller for the bafang hub??

[@TheHowtoDad]

bring it in to a local bike shop, they will be able to get it off for you

[@badcatbaby]

Thank you

Where did you buy this axle? I'm looking for the second day I can't find it.

[@DadBodForever]

How many amps are you pumping into that wheel? :)

[@miket9549]

I need help I replaced my gears and put everything back and now the magnets just spin but doesn't spin the wheel am I forgetting to put something back on

[@dietersautier2908]

great video: what kind of grease do you use?

[@TheHowtoDad]

dielectric or silicone grease

[@dietersautier2908]

@@TheHowtoDad Thanks. Do you have a brand?

[@Steveshappylittletrees]

What’s this all aboot?🤔

[@BrendaEM]

Congratulations. Of course, when you tapped the new motor shaft with a metal hammer, I almost jumped out of my seat. LOL! The epoxy on the windings was a good fix.

[@TheHowtoDad]

there were some sketchy moments...

[@markissboi3583]

Add statorate magnetic coolant cools magnets get 10% more power etc $20 10ml tube

[@FerdinandPinosan]

Where can i buy the axle?

[@gw877]

How did you know witch wires were for power?

[@TheHowtoDad]

the wires are all colour coded. I just matched them up

[@ibrahimjan4413]

can you please give me the link of that axle thing you ordered please 💞

[@TheHowtoDad]

unfortunately there is no link to the part...you need to contact the manufacture and ask them very nicely to send you one. Honestly, the easiest thing to do is buy a new motor and swap the internals.

[@ibrahimjan4413]

the new motor will cost me 300 hundred dollars

[@olyo167]

where would i get new planetay gears for m rattan 500w rear hub motor

[@GBPaddling]

My nylon planetary hub gears are fouling the alloy casing @ 2.27mins, it's as if it needs a shim or a spacer to just stand them off a little? 1mm would probably do it, any ideas on this?

[@robertmotion]

Great video. Question…does it matter if the hall sensor replacement is unipolar or bipolar? Can’t find any information online or on KZbin. /Bklyn👑

[@TheHowtoDad]

that is beyond my knowledge...

[@NabiL_Lam]

is it possible to change that axle to a thru axle so it fits modern bikes?

[@TheHowtoDad]

as far as I'm aware, no
