Здравствуйте, я из России, являюсь счастливым обладателем данного двигателя. Спасибо вам за видео, вы мне очень помогли, так как у нас никто это не умеет ремонтировать, я разобрал и почистил, заменил смазку уже второй раз, благодарю вас! Всем мир!
ive just had a yamaha motor repaired by this company and im well impressed by the service finnished product and turn around ten out of ten from me magic
This is one of the few channels on youtube that is actually useful. Watching this guy de mystify e bike motors is encouraging.
i now know that when my motor eventually fails , i will be able to send it to him for a repair.
He must be hated by Brose , Bosch , yamaha ,etc for educating the public about them hiding behind the word “proprietary ” .
Not really. I used to work for a major manufacturer of vehicles and while we encouraged the end-user to visit an authorized dealer for all repairs, we knew that most seeking repairs outside of warranty did not do so. There is no hatred involved. Remember that all dealers, authorized or not, are simply independent businessman, just like those who provide us parts and repairs for any vehicle, electric or otherwise. As for proprietary parts issues...those will always be with us. I am happy to see so much can be done with my Yamaha PW motor. It frankly very encouraging!
Great! I would say that it is not as easy as it might look. I have spent full 2 days doing it, but finally succeeded. I would say to anyone attempting to do it: do not even think without a bearing puller (both outer and inner), Yamaha 36mm tool, and hydraulic press. What they do not mention here is to be very thorough in cleaning and greasing afterward. Anyway, amazing video. If anyone from Serbia needs some advice on this, feel free to write :)
Very refreshing to find an honest video on how to replace the bearings. I have the knowledge but not the tooling so I wil be sending you my motor in the coming month. great video once more
Looking 4 it job dun on my bike 🚲
This Yahama motor seems to be better enginenerd than Brose or Bosch motors, thanks for showing this great video.
I dont think so. My brother has had a lot of problems with it.
ive just hada motor reoaired by this company and i am very impressed by the service and and the finnished job very efficient and speedy turn around ten out of ten from me
Thanks for such a clear and concise video. Just how all utube videos should be!
Great video. Will be sending my yamaha motor in for service next year !
how much was the service?
@@jerryx2000 it depends how many of the bearings need replacement. I paid around €100 plus postage as I got them all done. Fantastic bloke who has amazing customer service and knowledge.
@@Cheekeemunkey that is damn cheap. Where do you live? How is the motor holding up? I got the PWX2 and am very happy th-cam.com/video/QFu-uA6pgLI/w-d-xo.html
MUY BUENO AMIGO GRACIAS POR TU VIDEO.ERES GENIAL
super presentation, thank you very much!
Very helpful. An expert demonstration. Thanks!!
Great video, very helpful. Thank you so much.
Great channel. If I'll ever need to repair my eBikes engines, I'll send it to your shop :-)
Great video thanks a lot for sharing your expertise Sir
Awesome video
I will be send my motor to you for a full overhaul and service thanks.
Wonderful video, thanks so much. QUESTION: Why are so many viewers seeking advice, parts, information and even wanting contact information here on TH-cam? Why not just go to your website? I am beginning to understand why so many TH-cam creators have disabled comments. Thanks again!
Excellent question! It's tough because we get this number of questions for every video too, along with Facebook, WhatsApp, email, text and phone, so not a lot of work gets done 😂
You sir are a legend
Just watch this video brilliant making contact with you guys to order some bearings grease etc 👌
Took my Bosch motor to peter guy knows his stuff
Thanks for posting this video,very insightful
Thank you for this!
Awesome video!! thank you so much for taking the time to teach us ebikers how to repair the most intricate component on our bikes, can you tell me where abouts you're based and also do you ship parts to Scotland?
Hello Greg, We are based in the UK and ship world wide (Including Scotland :)
Who can watch this video and think "YES I'm gunna do this myself!"? Not me! I know where to send my motor when the time comes though.
Great video. Thanks
Спасибо за видео 😊
Пожалуйста.
Yamaha is top!!!!!
Why did it look so messy inside and why is water ingress an issue with them? Bosch looks cleaner from what I've seen.
Hi
I've just opened my PW-ST 2020 motor. Bearings are the same as the one shown on this video. The right crankshaft bearing started to make unwanted noise and I was able to feel some gap in the crankshaft
You're right about the bearings and you can buy them here: www.ebikemotorcentre.com/yamaha-pw-and-pw-se/
I was about to buy a used Giant Roam (syncdrive Core) for 1000 dollars less than a new . I realized that there was some play in the BB and for an almost new bike I suspected that it would be a major repair with crankcase opening. Question : Bafang engines like the new Ultra Max drive are more reliable ? Maybe too new , then the series BBSHD are a good reliable choice ? Thks
So that why Yamaha motors is a little bit noisy that Brose motors. Brose has belt and here we have direct connection between gears. Nice video though.
Yes, exactly.
Good Video, Txs..
I KNOW THIS MIGHT BE A LONG SHOT but have u got a link to the cable for this motor i bough one second hand and carnt find a cable anywhere for it, Thank you
have you ever thought about making a frame kit and a wire convertion kit that will allow swapping of motor to a different brand to fit the bike? especially for specialized bike customers who wants to change their motor to yamaha or shimano.
Yes, we have looked at this quite seriously. If you could get a different motor to talk to the original battery (changing both battery and motor is not normally economically viable) then getting the crank in the exact same position both left, right, back and forth will require a different fitting kit for almost every bike out there. It was not a viable project for us.
Great video. It looks like the drive gear on my PW has broken off where the locking nut thread is. I only noticed when washing the bike. No noise and no issues with riding. Would you know where to source the drive gear?
I would like to ask if it is necessary to use threadlocker for the six locking bolts.
Thanks for your super video.
These bolts don't tend to come loose on the Yamaha whether thread lock is used or not. There is normally more than enough thread lock left on the bolts but if in doubt it would not hurt to apply some semi permanent thread lock.
@@Ebikemotorcentre Thank you very much
Great info. Did you guys upload the PWX motor yet?
did i read in comments you ship world wide?. I'm from new zealand and i know at some stage in the future the motor is going to need an overhaul do you do the new zealand thing?or poss freight parts kit and find someone to do it i would do it if i had the gear . awesome work you do and easy to understand vis love them you simplify things :-)
Yes, we have suppliers all over the world, you can find our New Zealand supplier here www.performancelinebearings.com/suppliers/
@@Ebikemotorcentre thank you so much for that cheers
Great Video Pete, rare to find this kind of information. Can you help me understand on the Yamaha PW motor the 'type' of chainring found. I see a lot of different terms for the direct mounts, Qinch, etc. What direct mount system does Yamahs use?
Limited Grain. You're better off looking for a 'Yamaha PW Spider' then you can fit whichever chain ring you wish. I had to do this with my Giant 'Stance E+'.. The pressed steel direct mount chainring is very poor quality and alomost impossible to find a replacement. See my link here: www.tredz.co.uk/.FSA-Yamaha-e-Bike-Spider_204806.htm?source=aw&awc=6821_1591464323_bef90c4283868ce998fdb614a9e58d2b&
Hope this helps ?
A really late reply, But on the PW it uses the 104 BCD type. It's fits on the spider the motor comes with.. Which can actually house 2 chainrings or 1 chainring and a bash guard. Your chain stay will determine how big of chainring you can have as the inner.
Hi, how often you have usually to service an electric motor?
Great video, should mine need a service or repair I know where I'll be sending it. For general maintenance without removing/opening the motor, would you recommend spraying any lube into the motor bearings periodically? Would this be beneficial or detrimental? Thanks
Excellent question Lee. 99% of all ebike motors run "dry" i.e. they have no oil inside them. If you regularly spray a lubricant at the bearings it eventually makes its way into the motor and from there it makes a right mess! It can alter or dilute the greases, affect circuit boards and coatings, it also takes me hours to clean out if someone has done this. So, in answer to your question, don't, it's definitely detrimental.
@@Ebikemotorcentre thank you. Keep up the great work and I'll let you know when my motor needs a rebuild so i can bring it to you
@1200Pete great video! Do you repair just bearing problems?? I mean, are u able to get electronic parts?, like the torque sensor, or the electric motor parts, motherboard....
Currently it's only mechanical repairs but we are looking into the electronics and should be able to offer this service one day.
@@Ebikemotorcentre cool, I hope it will be an open market to get parts for repair...bearings are easy to find, but specific axle or gears I guess is just for brand service.
@@tizzadh If only it were all that easy, I looked for months to find the bearings so if you know where to find the crankshaft bearings with the groove cut in them the specific depth for the O-rings, please let me know because we have ours made. I can supply a few new parts now, like the plastic drive gear etc.
@@Ebikemotorcentre hehe I was talking about normal bearings but u are right, these specific bearings sure are difficult to find :)
Great video, very informative! I have a 2018 Giant Road E+1 Pro with over 14,000 miles covered and I have noticed some roughness when I spin the cranks with the chain removed! There is a little play in the cranks but not excessive! The motor isn't noisy but I'm guessing its probably time for an overhaul, most of my riding is in dry weather so how often would this require a service mileage wise? Do you have an overhaul kit in stock for the Syncdrive pro?
Hi Rab, these motors are not really service items and technically should be fit and forget items... However, as we know, they are affected by a number of things, but as to how often they should be serviced, I would recommend doing exactly what you have just done. If you notice the crank getting rough or noisy, time for a service/repair. Keep an eye on it though and never let it get too bad. (If you can hear the bearings while actually riding, it is too late!).
@@Ebikemotorcentre Many thanks for your quick reply, its very much appreciated. I will probably wait until winter and send the motor off to you for a full overhaul, I will keep an eye on it in the meantime though!
@@rabh6746 I will be gobsmacked if it lasts till winter time, but here when you need us.
@@Ebikemotorcentre Probably just wishful thinking on my part, what kind of turn around could I expect if I send it off soon?
@@rabh6746 Currently 10 to 12 working days 👍
After how many km & years should this be done?
Yamaha show a service being done in their manuals, but they don't say when this should happen!? There is two bronze bush bearings inside this motor that tend to bear into the crankshaft if they are not looked after and personally I would re-grease these every 2,000 to 3,000km
@@Ebikemotorcentre is it the same for the pw-x2? Internal build.
@@jerryx2000 Yes.
I am curious about the mounting standard of these ebike motors. Are they compatible in some degree. For example. A newer bike with a Bosch gen 4 cx motor. Is another brand able to mount in there. Like a flyon or a bafang, or yamaha or broise? It seems you mess with all of em so maybe you would know. I am certain the controller would have to be swapped as well. I am not a fan of the bosch anti tuning bs.
Sorry, no motor mount is compatible with any other competitor. You would also have to change the battery as well as the controller and all the looms.
Awesome video. Do u mind doing a vid on the giant syncdrive pro motor
Thank you, as soon as we get time the PW-X will be next (same as Giant Syncdrive pro)
1200Pete awesome thanks man 👌🤘. I’ve always been looking for someone who actually specialises in these motors because the syncdrive pro motor is quite unpopular.
The word you were looking for is "pawls" ;)
Thanks for the great video. Do you know the torque settings when you bolt the motor back in the bike frame?
Hi Rick, this can vary from manufacturer to manufacturer but Yamaha give a generic torque for the 8mm frame bolts of 19Nm. Haibike give a torque of 22Nm for example. I would ask your bikes manufacturer or try to find a manual for your particular bike.
@@Ebikemotorcentre Thanks for the answer. Shortly after I commented I realised that they say 22Nm on them, mine is a Haibike too.
Are there any home-gamer tools you recommend to do this (especially for the blind bearings and pressing bearings back on )?
How much do you charge for this strip down service?
*edit...I went to the website because that's what I should've done in the first place. Very reasonable pricing...I will definitely be in touch. Tool recomendations would be great though If you have any :)
You will definitely need a set of blind bearing pullers and the smaller of the two bearings can be tough to remove. I actually had a tool made in the end.
Yamaha are about the cheapest motor we repair, but as prices change regularly please contact me for latest pricing.
Thanks 1200Pete, appreciate the quick reply. Great video by the way, very concise and informative. :)
Hi my son got knocked of his bike and and the end of the crank shaft snapped, I have removed the crank shaft watching your video, it is the same motor you are fixing do you know where I could purchase the crank shaft, thankyou.
Yes, we have these in stock, both new and used depending on your budget. As prices change I can't post them here, but email me at enquiries@performancelinebearings.com and let us know what country you and we will be happy to help.
My left crank makes an awful noise when pushed, but not when just spinning without force. It sounds like two marbles rubbed against each other and only just before the top, say from 2 to 10 o’clock. Does that sound like a crank bearing to you? Only has 640 Kms and started 200 Kms ago. Bought it with 64 Kms and was not used very much in a rental fleet. I thought maybe the bearing grease has dried out.
I would remove the chain and turn the cranks by hand. If it is a bearing you should hear it, feel for play in the crank and contact me through www.performancelinebearings.com if you need anything or have further questions, I will be happy to help.
Great video. My PW works fine, but it doesn't have as much power as all the newer bikes/brands. Is there any way to upgrade the PW motor to get more power from it?
Only option is to fit a PW-SE motor and new controller. No cheap way that we have found yet.
@@Ebikemotorcentre Thanks. That's what I thought, but I was hoping you might have found a way. Just curious....what is the cost of doing a bearing job like your video describes?
@@wasuppa Take a look here: www.performancelinebearings.com/repair-overhaul-service/
@@wasuppa All the prices are on my website, or drop me an email. I can't put prices here because over the years they change. 👍
Hello.
Thanks for the videos.
I have a PW-SE motor and how can I develop thumb throttle?
Thanks Peter
I know people have done this but it's not something we currently get involved with. We just try to specialise on the mechanics of the motors.
@Ebikemotorcentre where can we get a bearing puller like the one in the video?
Just search U.S.PRO TOOLS AT091 👍
Excellent Video, I have a 2018 Haibike with a Yamaha PW motor. The motor started making one click noise on the down stroke of the pedals, Push the L/H pedal down and makes 1 click, Push the R/H pedal down same thing on this side. Tightened engine bolts, engine protector, chain ring, nothing help. The pedals thru the crank have no play up or down or sideways, tells me the bearing inside are good. Any ideas besides opening up the engine? Any help would be appreciated.
Cheers
I pulled the motor out of the bike frame and the 3 motor mount holes have become elongated.
@@1prozak614 Good news, shows your motor has been moving and I am sure your click will be gone once refitted and tightened (Don't go mad but go a little tighter than the recommended 22Nm).
Hallo.
Dankeschön für die Videos.
Ich habe PW-SE Motor und, wie kann ich Daumengas aufbauen.

Hi! I need to replace the brose planetary bearings. Would you help me?
Yes, I have them in stock.
Hey, great, but could you also me
or the others the
Share the size of the bearings.
greeting
Hi Marc, All the bearings are for sale on my website www.performancelinebearings.com I have spent a lot of money on motors to film, access bearing types and sizes. Some of the bearings, like Yamaha crankshaft bearings, are not standard, they have special sealing and groves cut for external O-rings. This is why it is easiest to buy from us, so you get the best and correct parts.
IF WE PUT SOME CERAMIC BEARINGS IN THE ENGINE IT WILL GO BETTER???
This would be very difficult with this motor because ceramic bearings will not be available with the O-ring grove cut in them. Also, they would be good against water but not contamination like dirt and grit. It is not really the bearings that affect the motors performance, it is the bearings seals, and you would still need good seals on the ceramic bearing, so once again defeating the object.
@@Ebikemotorcentre do you have to bring the board? thank you
bearings can be damaged in 6 months
@@jordidelval3725 Yes, especially if a power washer is used or the bike is ridden through deep water.

Hi again! I am struggling to remove the motor from the frame. My PW-X is held up in 4 screws (2xM6, 2xM8) which I completely removed and yet.. the motor doesn't want to come out. Any suggestions? Did you also struggle with removing the one in this video?
Hi, The PW-X can be very tight in the frame, it also needs to come out at the right angle. You could gently lever the motor with a bar or large screw driver and you should see it move. If there is no movement don't force it and get help.
My Haibike all mtn got submerged in a river, would you have a look at my motor? How do we get in touch with you?
Just email me, enquiries@performancelinebearings.com 👍
i have one of the Haibikes with the yamaha set up.....how reliable are they? ive covered over a 1000 dry miles on mine and now its probably 5 years old...
Yamaha are a very reliable motor if kept dry. They can suffer some printed circuit board failures, and the occasional stripped plastic gear but in general they are good.
My other question is do grease go on the needle bearings??
The only needle bearing is the clutch bearing inside the plastic gear and this should be pre-greased (don't use high pressure, Teflon or ceramic based greases on the clutch bearing if you do need to grease it).
How can I contact you to send my motor for changing bearings
Thanks
Are the torque sensors sprung ?
No.
Ok. So am I right in thinking the torque sensor distorts slightly with the pressure from the peddles and would change the inner wires length to send the input signal
1200pete, have you had a chance to work on the new PW-ST? Is there any visible differences inside when compared to the PW X? Externally they look incredibly similar
They have the same square drive crank as the PW and PW-SE so I would expect them to be very similar inside. Because these are all still in warranty we wont see them for another year or so.
@@Ebikemotorcentre thanks, it'll be interesting to find out
Hello,i have a giant e+2 with yamaha syncdrive.most of the time you can t hear the motor when cycling but sometimes i can hear a grinding sound,maybe for 10 seconds and then it goes away again.the noise never gets worser .the noise is also not constantely.is this a bearing problem or is it just how the motor sounds?i ve just bought the bike 2nd hand .before this i had a bosh e bike so i can t make a comparision.thx
Your issue, does not sound like a bearing. If a bearing is bad enough to "grind" you would normally know something was badly wrong. Can you feel anything through your feet when this happens? Can you replicate it by turning the cranks by hand without the chain on? Does the crankshaft feel smooth while turning by hand? Is there any up and down play in the crankshaft? Is there enough gap between the chainring spider and the motor cover?
Hello first of all,thank you for answering my question.i will tomorow check all the things you told me to do and then i will let you know what i found.big thx 👍👍
Hi! My 2019 PW-X motor seems to be using more battery than in the past. Changed my chainrings, cassette, chain.. but I see no improvement. Is it possible that it is a bearing problem? I don't hear any strange noise.
Remove the chain from the chainring and spin the crank. If it feels free its not your bearings. It is more likely to be a dying battery? Has it been stored at room temperature and kept at 60% ish. Or has the battery been left flat or fully charged for long periods or stored at low temperatures? Any of these will degrade the battery.
@@Ebikemotorcentre Thanks for the quick response! I have 2 bikes with the same yamaha 500Wh battery, mine has 6500 Km, my GF's 2500 Km.. I also tried to ride with her battery but I still see the same range.
Is it possible to inspect the state of the bearings without removing them? As my bike warranty expired in January, I guess there's no problem if I open the motor at this point.
I did spin the cranks with the chain off when I replaced the chain but I can't remember exactly what I felt at that time.. I guess it was ok'ish at least otherwise I would've noticed it easily, right?
@@sterpumihai If you're happy to, I would remove the side cover and see what the smaller motor and gear shaft support bearings feel like? It is not unusual to have the drive gear support bearing seize and this puts a lot of drag on the electric motor. Please email me if you have further questions enquiries@performancelinebearings.com
Sorry, I had to remove your link. The part you need is a crank puller for an ISIS drive crank www.performancelinebearings.com/product/crank-arm-puller/
Which type of DC motor is in it?
I am trying to find a teardown video.
Is it a brushless DC motor?
Yes, most ebike motors are brushless.
Didn't look like the torque sensor bearing got any grease.
This is because there is no bearing inside the torque sensor, it runs on a self lubricating plastic sleeve.
@@Ebikemotorcentre A little grease can't hurt; even there.
How about a video comparing all the motors and which one you think is the best made and best to repair?
@@bigwheelsturning The torque sensor is finely calibrated and technically should not be stripped. We do grease the splines but to grease the moving parts internally it would require stripping. With regards a comparison video. We know exactly which motors are the best and worse and why, but I am a firm believer that you should buy a bike with your heart, not your head. If we said which is the best motor out there, some would buy a bike just for that reason! You should buy a bike for the way it rides and the way it makes you feel, not what motor it has. At the end of the day, if you keep the water out of them, all e-bike motors are all relatively reliable, regardless of what you read on the forums.
My pwx motor feels notchy. Especially noticeable when in the small gears. Do I just need new bearings?
If you're sure this is not coming from the drive train then notchy feeling on a PW-X can be bearings if accompanied by grating noise. If relatively quiet it can also be gearing. Either way, do not be tempted to keep riding it. Get it looked at before any serious damage occurs.
@@Ebikemotorcentre Thanks for the reply. There is no noise as far as I can tell. Do you mean the motors internal gears?
@@gabriels1163 I have just read your original question and now understand you were meaning a notchy feeling from the chain and sprockets. I would suspect these before looking at the motor.
My question is after over hauling of the moto . Do the moto has or have to be updated??
No, nothing changes so no software changes needed.
What´s the name of the Bearings in the motor?
Hi Jasper, do you mean the type of bearing i.e. ball bearing or needle roller bearing? Or did you mean the manufacturer? Or the bearing designations?
@@Ebikemotorcentre My pw-x motor i making more noise than before. espassely in the woods. So i thing te bearings are worn out.
You mentioned a webpage were you can order the bearings you need. i looked at that webpage, but could not find anything regarding to E-Bikes. So witch bearings do i need to make my motor run smooth again :
Thanks :)
We only have bearings for the PW motor at the moment. I have not been able to get hold of a PW-X motor to source the bearings as of yet. If you would like us to repair it I can source the bearings once the motor is stripped down. The page on my site is www.performancelinebearings.com/shop/
@@Ebikemotorcentre For now i wait for my dealer to tjek if its under warrenty. my engien is only 1 year old. if not, i may contact you again, for a repair :)
Yamaha motors suck cuz they don't protect the bearings from dirt n water coming in. I was driving it for 3 months and it was done for. Next thing with the yamaha motors they don't shift to neutral so it's literally impossible to reach and hold speeds over 25km/h and once the battery is empty the bike is ridiculously hard to move - any small hill and you can walk
Hi is this the same motor fitted to my Giant Fathom e+1 2019 model? A quick chat with the LBS suggests unlike bosch motors its not servicable, hopefully this isnt the case, please advise thank you!
Hi Tom, Yes, you have a very similar motor fitted. You will have the Yamaha PW-X motor in your bike (branded Giant). It is serviceable. We stock the bearings for the PW-X or can service/repair it for you.
can the engine easily damage when ridin in the rain?
No, rain will not cause too many issues. Road puddles are not an issue either, floods should be avoided if deeper than the crank.
What size bearings go inside? 2015 Yamaha PW please???
If you buy your bearings from us or one of our suppliers they will all be measurable for the size. Some of the bearings for this motor have to be manufactured or altered.
Looks a much more "fragile" internal set up than the Bosch CX, and very different....
It is. But, although it is a more simple design, with more basic engineering, it's still not a bad motor.
@@Ebikemotorcentre I have the SE version, I wouldn't say it's a bad motor, I would say it's an excellent motor! I guess simple engineering doesn't necessarily mean simple performance. I have one question (Sorry if it sounds a bit noob): But when you say "Noise" What sort of noise would I be hearing out for? My motor naturally has quite a prominent sound when it's doing it's thing...
@@mozzjones6943 Bearing noise is generally a grumbling or grinding sort of noise. High pitch whining can be gear noise or motor support bearings. These motors are normally a little whiny, but when they go bad, you will know about it.
@@Ebikemotorcentre Cheers fella!
@
Barry Corney Yamaha started making e-bike motors 11 years before Bosch did.
In Japan Yamaha motors are a must where off course in Europe there will be better distribution of Bosch motors due to stock availability and delivery time.
About how many miles on bike before this needs to be done?
This really depends on the terrain you ride on, what weather you ride in and how you clean your bike. But with the Yamaha motor, I would clean and re-grease at approx. 2,000 to 3,000 miles. (3,000 to 5,000 km)
Does anyone know if I can simply connect another battery to the motor contacts instead of the Yamaha battery?
i want to use car batteries with a stepup module to 36V because i want to load the batteries while driving with solar panels in a trailer.
Try here www.avdweb.nl/ This guy has done a solar bike.
Will this overhaul kit work for a Yamaha PW ST? The ST is the newer version of the SE but the bearings may be different? Many thanks.
We have not yet seen inside an ST as they are generally all under warranty, but rest assured that we will support the ST when people need us to.
@@Ebikemotorcentre fantastic, thanks for that, will take note. Just wanted to make sure the ST will have enough parts to fix/freshen with new bearings etc. I’m one of those guys that like to have spares and back up for my motors 👍 cheers.
Hi I have A problem with my engine when I was there it made noise since my pedal hit the pavement in your opinion what please Haibike SDURO FullSeven LT 4.0 2018 thank you????
Pedal strikes can result in broken gears or internal circlips. It should be investigated as soon as possible.

What motor do you have, PW Series 1, 2, 3, or PW-SE Series 1 or 2, PW-X, PW-X2, etc. If you're unsure, just give me the number on the silver sticker on the bottom of your motor and I will fit the corresponding motor into our test bike and let you know what the voltage is.
@@Ebikemotorcentre it's the haibike sduro hardseven 1 2018 yamaha. The motor is the Yamaha PW Crank Drive 36V 250 Watt. 50 - 280% Assist, 70Nm. Does this help? I will strip the bike and get the number to you shortly aswell
The number on the silver sticker is X0X20
5048535
Thanks I appreciate you're help 👍
@@kevtins3949 This is a PW Series 2. The output on our test bike is variable, there is a low rolling voltage that cycles between 1 or 2V to 0.08V so nowhere near 26V. Hope this helps.
@@Ebikemotorcentre was this on the brown to earth, yes I had similar outputs on the other wires
Can you repair motor water damage after its done???
Sometimes. The problem with Yamaha is that they fitted the circuit board at the bottom of the motor. This means any water entering the motor hits the circuit board and does not do it much good. Sometimes this damage can be cleaned and repaired and sometimes it is too bad to repair.
@@Ebikemotorcentre any chance average electric repair specialist can do it ? My yamaha screen showed e12 and e15 errors and now it wont turn on.
@@wiktorwisniewski5748 They have a triple layer sandwich board and the water tends to soak up between the layers but if just one of the outboard components have failed, it's worth someone having a look.
How often clutch bearing is wearing faster than main bearing? I've started hear some "ratchet" sound when motor disconnects (stop pedaling or reach max speed 25kmh). I think it could be clutch bearing, but there is no play in cranks or whatsoever. Just rattling for 2-3 seconds.
Never known a clutch bearing to fail before the crank bearings yet?
@1200Pete ok, understood. Is it possible to regrease everything without removing bearings? Like clutch bearing for example, it looks like there are no options to grease it without transfer gear disassemby.
@@AiSavvy I would be looking more at your motors freewheel ratchet and pawl mechanism, it maybe this that is failing? The pawls get stuck if they have been over greased. I would be extremely surprised if it turned out to be anything to do with the actual clutch bearing. If the clutch bearing is failing, grease will not help.
Personally, I would take a look first or send your motor to us for inspection.
@@Ebikemotorcentre I'd like to send it to you, but I'm living in Ukraine, and it's my commuter bike) Thanks for the info, will try to disassemble it first and regrease.
@@AiSavvy We do motors from all over the world but if you get stuck feel free to email be through enquiries@performancelinebearings.com 👍
Ho un problema, mi da errore 26 ( Er 26) sul display, come posso risolvere ?
Il codice 26 potrebbe essere causato da un problema con il sensore di coppia, la scheda del sensore di coppia, il circuito principale o entrambi.
@@EbikemotorcentreGrazie, ho risolto con la procedura per risolvere errore 28, procedura che si trova qui su youtube, ad aprire il motore proprio non ci volevo provare, grazie di nuovo
Hi, my question : What is the Difference between the Giant Syncdrive and a yamaha motor ? i now, both where made by yamaha..But what is the Difference ? :)
Software is the only difference I can find. All the internal parts are identical. Oh, and one has a different badge on the later ones.
@@Ebikemotorcentre Hi, First of all "Big thumb up" for your Great work...
Txs, for your quick answear, just a personal question : Yamaha or Bosch Motors ?
I´m looking for a Ebike..:)
@@danilos767 My politically correct answer is, most motors are good these days. I think you should buy the bike you like, regardless of what motor it uses. Don't pay too much attention to the forums and enjoy what ever you decide to buy.
@@Ebikemotorcentre Yeahhh, true ! My problem is...i got a Yamaha MT01 , yamaha tmax...hahha so, from start i´m a japanese Friend..:)
when we know that the bearings have to be changed, thanks
I have done a short video on this here: th-cam.com/video/fODuzkzxMXo/w-d-xo.html
Hi, my yamaha pw-se has just started a creaking noise and it gets louder every time i go out, I am not convinced it is the motor bearings because of the sound, when pedaling uphill it sounds like you are winding a clock up, does this sound like bearings to you or something simpler like the engine loose in the frame ? , I would value your opinion thanks
On the Yamaha it's usually loose chainring bolts, causing the chainring to creak on the spider. If not that, try motor bolts or saddle stem. lastly try rear suspension linkage if you have it? Good luck and if it does turn out to be the motor, you know where to find us.
1200Pete Thanks for the advice Pete, I have stripped it down and rebuilt it, with new chain ring, there was a minute bit of play in the axle but nothing that would worry me and the seals look good, I will buy a bearing set off you next month anyway ready for when it needs doing cheers
1200Pete You were spot on Pete, New chain ring and bolts and squeaking gone So a bit more life yet Thanks
@@Ebikemotorcentre excellent advise, cheers
HI have one of these motors fitted in a giant bike it was all working fine then on the next day after wheeling it backwards out of the shed it locked up and now theres a lot of resistance on the motor but only when pushing backwards, also it will no longer turn on. would one of your bearing kits sort this broblem or at least one of them ?
Hi Gemma, It sounds like water may have got into your motor? If this happens it can seize one or some of the bearings and from your symptoms it maybe the crankshaft needle roller bearing is seizing up. If enough water enters the motor it will reach the circuit board and this maybe why it is not switching on anymore. Did you jet wash your bike? Contact me through www.performancelinebearings.com I maybe able to help.
hi question..where is the fuse on synkdrive pro?
There are no physical fuses that can be changed.
@@Ebikemotorcentre thanks for that info..my bike has stoped after i shorted the charger dc main power wires ..now it wont go.iv pulled the battery apart and can see no burnt bits on bms and seens cells are good as its 36v..it was about half charge so looks good.
giant dealer dosent know ither and giant is in lock down for c19..if you have any ideas it would be apreciated..thanks.
ps my bike is not under waranty as i baught it second hand.
@@russellwilson5246 Unfortunately, the BMS may look ok but the circuit protection system may have done its job and popped without sign. I don't think it would have got as far as the motors PCB but you need to speak with someone who is an electronics engineer. I would have thought it should be a relatively easy fix. Unfortunately, we can't help with fault finding to component level.
@@Ebikemotorcentre just this bit of information has helped..thank you...i dont supose you have any hints as to were i could buy a standard ome bms for it? it may be that the system will only recognise ome bms?
@@russellwilson5246 No sorry, we do not currently get involved with batteries at all, just motors.
less bearings than my bloody brose motor
you can not put a paper gasket, like the head gasket, thanks
No, this would change the pre-load in the crankshaft bearings and allow more end float on the crankshaft.
