Bike Mechanic, I feel like there should be a right to repair law similar to iPhone, but for Shimano di2 and other products. Shimano should be required to sell all individual parts for their products as well as make any special tools easily available, and to set up regional repair centers to send in things like brifters and derailleurs for repair.
Hi, Thanks for watching and your comments
100% this should be the case. The right to repair laws say so. Of course this can be via trained and authorised service shops / LBS but either way it should be talked about more.
Excellent video, thank you for taking the time and afford to make it.
One thing i always do when taking an unfamiliar engine apart is to make notes from the steps i take as well.
When assembling just reverse the list and there is almost no chance to forget where everything goes.
Hi, Thanks for watching, even better still, video it all, :-)
@@TheYorkshireBikeMechanic I wish i had the skills to video and edit.😢. Can fix almost anything mechanically, but have no computer skills.
Hi, Dave. Thank you very much for sharing this video! I have just sent my E8000 to shimano UK and if they fail to fix it I will take it to you to have a look at it. I live in Brazil and will be travelling to Manchester next month. Regards, Francisco.
Hi, Shimano should sort it for you if it's in warranty, if not they might offer an alternative solution. let me know how you get on.
Thank you for this video!
It gave me the confidence to tackle the bearing replacement.
Thanks for watching
It’s dead simple don’t be afraid…..
I’ve just last week done this on a customers bike and it was not easy at all very difficult but it was my first time so hopefully gets easier the more I do it, great video 👌
Hi thanks for watching, I would say out of all the motors this is by far the most trickiest thanks for the thumbs up.
Hello, where did you get the bearings, or could you please give me the dimensions? This would be so very nice, if you could help me. Albert
Excellent video. don't need it doing yet but would be confident after watching this, well done.
Glad you enjoyed it, thanks for watching
I managed to rebuild my motor with the help of this video, so thank you very much. I sourced the bearings from a local dealer. They are pretty basic bearings. Couple of points to add. The crankshaft in mine was pretty stuck so it needed some gentle punding to come off. Also the other needle bearing is behind the seal the seal needs to come off temporarily in order to change that.
Hi, Thanks for watching and your comment
HI, in my case i am not able to get off the crankshaft , how will you get it ? is there any part , like circlips o something that seems it avoid the cranckshaft release. thanks in advance
@@pedroantoniozorzo2901no, there is only the one circlip on the "bottom" side which is shown in the video as well. I assume you removed that. There is some horizontal play in the crankshaft. That may be the clutch. Make sure you take that play out before pounding it. It took some harder pounds with a mallet. It definetly was the scariest part since it's hard to know how much force would brake something. I later thought that mabye some WD40 or similar might have made that easier. The part that is sticking is the bores right on the inner side of the bearing.
The circlip on the outside is very malleable and easily deformed. I am considering replacing mine with a better quality one. Thanks for your video. It took me approximately 3 and a half hours to do the whole job. Quite nerve wracking but very satisfied with the result. I have rebuilt hundreds of motorcycle engines so dealing with the tiny wires and circuit boards is a bit of an eye opener. Rejoining the wire ribbon is a trick!! You need to be careful not to put too much grease in the blind bearing holes as it creates a seal that pressurises the cavity when you try to insert the bearing and the shaft. I have been a cycle and motorcycle mechanic for 50 years so I have experienced this before on petrol engines. Cheers .
Hi Francis, great comments, thank you. I also have an interest in motorcycle engines, in fact any engine.
Thank you so much for this video and recomending those replacement bearing kit for us!
Our pleasure!
Just done mine , followed your vid , motors better than when I bought the bike ty
What a good doo, Thanks
Heyup Dave. Watched your video with fear and trepidation. My E8000 has done about 14,500 km, but even now it still sounds much the same as the day I bought the bike. Suppose there'll come that fateful day when your excellent video will be indispensable to me . I totally agree with your philosophy, if at first you don't succeed, buy a new engine. Oh yes, battery still very good too.
Hi Derek, Thanks for watching and your comments.
good morning @delzworld2007 . I have a bike with the E 7000. I was curious if you still have yours and what mileage has your engine done? Anyway... I'm looking for information about durability of Shimano engines.
I can see where a support stand would come in handy for this, much like there is for Holley and Rochester 4 barrel carburetors. But the support pin heights would need to be different to match this motor.
Props to having the time to make this video man
Thank you
Great video and thanks for your effort, I have an EP8 that has an internal problem that Shimano will not warrant because I'm the second owner. No one services the motors in Australia so its replacement only at $2200 so I will be doing it myself, thanks again for the helpful tips..
Hi Grant, good luck. be careful
Excellent stuff, look forward to seeing other manufacturer motor, videos :)
Thank you!
Thanks Dave for the video, you've convinced me to not buy any bike with a Shimano motor in it. Whew, that was actually a close one :)
Hi, Thanks for watching and your comments
That was really, really great Dave, thanks so much, as you say, if the warranty's up, then the cost of the bearings, and tools are a small pricen to pay if it's "sh*t or bust" if you'll excuse the expression !
Hi, thanks for watching and your comments, expression excused.
Very scary if the warranty period is lost after 2 years ,hope there is reliable technician like you in my country sir 👍
Hi, Thank you for your comment
Thanks for your detail instruktion by video. This was very helpfull. I have done it! 👍
Thank you for sharing your knowledge and experience, well made video, i hope this will bring me further now… cheers mate! Greetings from Germany!
Hi, thanks for watching and your comment.
Thanks for the video, I'd wondered what the internals look like! I have an E8000 and it is feeling very "draggy", not rough or noisy, just like there is a lot of resistance. Its out of warranty so not sure what to do about it. I'd love to upgrade to the EP8 and wish Shimano allowed some kind of upgrade/conversion, I know physically it fits but electrically it apparently does not :(. Thanks for putting this together!
Thanks for watching!
Great vid Dave, very interesting. Can you do one for a Bosch motor, I believe they can be rebuilt also. Certainly doable but one for the shop, 👍
Hi Paulo, yes we can do bosch, brose, yamaha and shimano e8000, all of them are not easy and would advise professionals to do them.
Very interesting and useful video, thank you!
Glad it was helpful!, thanks for watching.
Great video. Let's hope I will not need to do that, although as a trained car mechanic I am sure this is well within my capabilities.
Hi, Thanks for watching, a tricky one to say the least. there are some parts that are not available, like the 3 main shaft seals, they are not available to buy and are shimano bespoke items
Hello, could you make a video for the shimano ep8? He often has a crank axle play problem. Many thanks for your work and for sharing your investigation.
Thanks for watching and your comments, ep8s are very hard to work on, sorry
Is there any axle seals to replace? Wondering if bearing kit is enough with some sealant tube. Thsnks for the video btw!
Very clear instructions here. Thanks. Just to note you did not show putting the circling back on the shaft to complete.
While tricky it actual looks easier than the Bosh performance line motor. Less bearings. Shame that the seals are not available as water ingress is a real issue with eMTB motors.
With no obvious water damage i.e.corrosion, 2500 miles really is not excessive to need a full bearing change for wear. This represents less than 10 miles a day for a year. Disappointing. Can better quality replacement bearing be sourced?
Hi Steve, It's probably the trickiest motor to do, there is so much going on and its all right where you can accidentally damage it. Regarding the bearing wear, failure of bearings are often due to water ingress as you say, some users use jetwash?, it only take a small amount of water to start the damage process. Thanks for your comments.
I've got an issue with an intermittent torque sensor fault accompanied by E010 on my E8000 after pedal strike on a rock, so I followed your video to take a look inside. I was hoping to see a loose ribbon cable, but nothing looked obviously wrong, apart from the fact that I was not able to separate the crank shaft from the torque sensor. It seemed to separate much easier for you and I wonder if that has anything to do with the error I'm seeing. Great video, thoroughly enjoyed the process!
Hi, Thanks for watching and your comments, You may not see anything inside that may look to cause errors, this is the main problem, the motors are so sensitive. The torque sensor can be stuck on the crankshaft, the one way bearings cause it to stick on and are very difficult to remove without damage, the ribbons tear away. you are very lucky if it slides of the shaft. it's the most difficult motor to work on and I advise against it.
Hi Can the torque sensor be replaced as I had mine plugged in and it’s giving a error on torque sensor?thanks
Brilliant video Dave, thanks for sharing, I've always wondered if it were possible to overhaul a Shimano motor 😀 There's plenty about Bosch motors and I've done my own, but like you said there's none on Shimano. 👍🏻👍🏻
Hi Michael, yes they can be done, only the e8000 for now. very tricky though
@@TheYorkshireBikeMechanic yes I can imagine!! You made it look easy though Dave 😉
благодарю за Ваш опыт
Great video , repairing mine at the moment , and having trouble with the needle bearing on the drive side we’re you able to change that, didn’t see that in the video.
Hi, thanks for watching, yes I was but they can be very tight on the shaft
uuuuaaaauuuuu !!!
What a video !!! Thks a lot !!
I am overhauling my e8000, and replacing all bearings.
Can you tell me, what are the greases that I can apply ??
there's a white and a black one,
I have some doubts on the whaite grease. I've read lithim grease, green motoreax, dielectric... and so on... and i'm very confused..
Thanks and congratulations
Hi, Thanks for watching and your comments
Hi Dave, interesting video, just wondered why you didnt replace the main shaft seals at the same time as surely they are crucial to keeping the unit water/dirt free?
Hi Phil. Thanks for watching, for the simple reason is they are not an available part. Bespoke by shimano and not available to us simple mortals
Wow what a incredible video ❤
Hey Dave watched your motor removal and it worked a treat..replacement bearing got crank shaft and wouldnt pull out of speed sensor any tricks a i wiggled and wiggle wouldnt come out?
Hi John, this is very common, the problem is that the sensor connector ribbons are very very easy to damage, I don't have an answer for you as too much pushing and knocking will damage the sensors.
Internally the motor parts look well built and sturdy and like cars bearing here and there needing replacing, I read and see a lot of E010 errors of peoples motors been knackered and need replacing, Is this like inside of a computer a motherboard hardware problem rather than the moving parts been a problem? If so would replacing the motherboards on these not be thee answer?
Hi, Thanks for watching and for your great comments. The only reason anyone would dismantle the motor would be to replace the bearings because they are noisy, everything else inside the motor is not serviceable and are not available to buy as parts and when motors are out of warranty. Having said that Shimano will offer to consider a repair or replacement at a discount under their out of warranty scheme, providing that the motors have not dismantled and not been tuned.
Thanks for the well explained instructional video it’s very well done. I have an E8000 that I believe has a buggered bearing so will need to dissect it to inspect the damage. I’m in Australia and parts are not available for at least 9 months. I’m thinking (hoping) I would be able to get a bearing form a local bearing supplier. Would you happen to know what bearing part number/dimensions for this unit would be?
Thanks again for the well thought out video.
Hi, All the bearings are available here, www.ebikemotorcentre.com/
I advise not to try and replace the bearings, damage is so easy to do on these motors
@TheYorkshireBikeMechanic strange comment advising not to replace bearings but selling them... note taken and thanks for the heads up re possible damage. I'll try to dismantle ans6see how I go a d order bearings of successful. Do you sell complete motor units?
Dismantled motor and the main bearing was totally destroyed. Managed to source one locally and got motor going again.
Thank you again for the very helpful video
Awesome video Dave.
I'm waiting to have some drift sleeves made to press the largest 2 bearings on to their respective shafts. Basically steel pipe just wider than the diameter of the shaft, but no wider than the beating inner race.
Can I ask a question.
There is a 2nd roller needle bearing in the outer most gear sub assembly (the one that has the biggest bearing fitted). Does that neddle bearing also just pop out or does it need to be driven out with a drift or puller?
Hi, Thank you for watching and your comments, Im trying to think how they came out and to be honest without stripping another one down I couldn't remember. sorry
@@TheYorkshireBikeMechanic it was obvious once I disassembled the motor. Your video was exceptionally helpful in the end.
I had some bearing play and had planned to replace them, then at the weekend my drive side bearing had disintegrated and seized the cranks. Now all bearings replaced and motor is singing a tune again. 😀
Saved me a fortune 👍
Magic video mate, Do you know if it is the same for the EP8 motor ? Cheers
Hi George, thanks for watching, To be honest I have not looked at stripping an ep8 because they are all still in warranty.
my e7000 started making some very weird noises after exactly 4000km. any ideas? they don't start immediately as soon as i start pedaling but lets say after i put some stress on it
Hi! I was about to order the bearings to do this maintenance but then i saw your video again and heard you say noise from bearings are audible also with the motor off. Well, mine does a Hell of a noise but not with the motor off, so i'm a bit lost now. Is a very strange noise, specially in high torque uses, trail and boost, but motor feels good, is just the noise... Sort of vivration... Idk...
Alredy open the motor and bearings fell really good, so if you have any ideas they are more than wellcome... My friends are fed up of my noisy bike lol, It sounds like an ill duck with every pedal stroke. Thanks a lot! Great videos!!! Keep It Up!!
Hi, Thanks for watching and your comments. shimano motors tend to have a whine when under load, even newish e8000 will whine. when you compare it against others of a similar age is yours much noisier.
@@TheYorkshireBikeMechanic much much noiser yeah, i recognise the whine you are talking about but i think this something else, is there a way i can send you a vídeo or something so you can hear It? Thanks for your help!!
Thanks for this great video, but I can’t loosen the aixle, any advices, thanks Peter
Hi Peter, It will be stuck on the roller bearing near the casing, From my point of view it's difficult to advise because I'm not with you to see it, it this case you would normally need to strip it down further to remove the axle. Its a super tricky job and very easy to damage, I would not recommend it.
Hi, first of all thank for the greta video you posted, it's the only one in the internet with the whole process.
My Shimano motor was making a nasty noise I was able to find in some videos and people was saying it was the bearings F..ed. I was going to buy the bearings and do it myself but as I had to buy the extractors and the press to install the new ones I finally decided to take it to one guy that makes these jobs for some local shops here in Spain.
The thin gis I just got my Shimano motor serviced, the guy that made the job replaced the same bearingns you replaced but the nois is still there, I have a noise from the engine when the wheel spins backwards (while cleaning the chain) and also on climbs. the noise disapears for a fes second if I stop pedaling and start pedaling again.
I thin kthe issue may come from those sprag bearings you mention. Do you know the service parts of those sprag bearings? I'm prety sure Shimano just buys them I don't think they will manufacture themselves.
The noise are these:

Again thanks a lot for all the effort put in that video
Hi, Thanks for watching and your comment, sorry for the late reply. all the bearings are available form , performance line bearings, they have international partners too. The shimano motors are so difficult to service, not many will do it here in the uk.
@@TheYorkshireBikeMechanic Thanks for your reply, also the spragbearings are available in performanceline bearings? Do you have any reference I can lok for? Thanks a million.
Thanks for the video. It`s really helping me alot. But I really have a problem to get the shaft out of the part you show at 21:18. The sprague bearing is stuck in my motor and needs to be replaced and the shaft wont get loose. Any Tips ? And also do you know where the right sprague bearing can be found ? Thanks for your work. Greetings from Austria
I have no tips as is case differs in how it comes apart, some easy some are a nightmare. bearings etc found here, www.ebikemotorcentre.com/
Hi Dave, great video. But I have a question. In the video, at 9.06 minutes, when you lift the engine, we see a ring that stayed on the carpet. I don’t understand where this ring was going. Can you help me? Thank you very much.
Hi Jarome, Thanks for watching. that ring fits on the axle end, its a crank arm stop ring. see czcams.com/video/YWFZh4WKhv4/video.html at 14.26
Hi Dave great video have you got one for the e7000 earlier model motor also do you sell the bearing kit for them thanks ?
Hi, The e7000 motors are not possible to repair as far as I am aware
Hello, this video is awe-inspiring! 🙇I would probably suffer a nervous breakdown if I had to do this on my motor... 😲
One quick question about motor-noise diagnostics:
What is the reason for scratching, duck-like noises that occur only (and even then only sometimes) when pedalling uphill ? Could it be the bearings still?...would dysfunctional bearings make noises all the time, even when assist is off?
Thanks a lot from a "mere rider"😉
Hi, Thanks for watching, you will know when the bearings are worn, turn the motor with the pedals when the motor is off, there will be really rough grating noise. other types of noises are hard to explain without having the bike in front of me.
@@TheYorkshireBikeMechanic
Thanks so much for replying!👍👏 one subscriber +!
So that's not the case here... With motor off, or even while riding on even roads with motor on-- no unusual sounds...
On uphill drive with full engagement of the motor there is a buildup of that pulsating scratch-, coarse duck-quack-like like, scraping noise, pulsating at ± double speed compared to pedaling frequency...
It immediately stops when I pedal on with assist off...
Still, the motor seems to be fully functional so far...
I suspect it's connected to heat buildup?
Or I had put too much stress on the motor wiring itself...?
(by pulling a buddy on his non-E bike uphill with a rope for example...am a rather relentless rider, too😁😊)
Thanks for your attention...
Sur les 6 vis qui maintiennent le moteur au cadre, avez vous mis du frein filet afin que les vis ne ce dévissent pas ?
Excellent video :)
Thank you very much!
Thank you very much for the very helpful video. Since my E8000 is constructed slightly differently, the clutch magnet unfortunately broke. can someone tell me where I can buy this? It's a little gray ring. Can be seen in the video at 15:03
Thank you for watching and your nice comments., only by using used parts this can be done
Ay up and howdo dave, I'm off injured so thanks for the input. What you didn't say dave, was how much is the bearing over all, and is it the same on a 2021 Bosch?
Hi, The cost is £235.00 plus postage, its the same on all motors out of warranty
Inspired by your video, I took my motor to bits and, unfortuneately I broke the ferrite(?) ring on the main shaft (the one with the torque sensor). Do you know of anyone who has spares for these motors?
Thanks for this great video.
Hi, sorry that things have not gone as well as you hoped, depending on where abouts you are is to send your motor to Peter at performance line bearings and ask him if he can possibly fix it for you
@@TheYorkshireBikeMechanic Hi, I checked out their website and found that they do not do any Shimano! Nor does their partner here in France. I shall keep looking and, if I find anything interesting, I will post it here. Thanks anyway. Keep up the good work!
Hey Dave, thanks for sharing. Really appreciate that. Just wondering if you have any spare parts for sale, or any used ones? As my mechanic opened e8000 and discovered one pinion gear's teeth (the one on your left hand at 10:36) is damaged instead of the bearings. Sad.
Hi, Thanks for watching and your comment. sorry I dont have any e8000 motors in the strip down.
Top video!
Thanks!
Hi, great stuff, but you did not show how to replace the needle bearing and the largest bearing on the largest/outermost gear ring. Can you plese tell what tool you use for them. Thanks, and all the best, KM
Thanks for watching and your comments, I made some press tools on the lathe for each bearing including the needle ones.
@@TheYorkshireBikeMechanic Hi, thanks for the reply. I have e7000 motor and maybe its different, but to me there does not seem to be a way to push the needle bearing out since I cannot see a surface to push on - just a little bit of rubber and the rest looks like gear ring surface. But maybe I am wrong.
Thanks Dave.. great video. Do you know approximately how much time or km's are on this motor before this bearing rebuild?? Thanks
Hi, Thanks for watching, the bike has 5085km on it
My first motor started the clunks on 3500 km (got replacement from Shimano) and second one (reolacement) at 2800 km..
Hi Dave, great video! Thanks for sharing. Could you provide the bearings info and where to source them from? Thanks!
Hi Ron, We use Enduro Bearings, they can be bought online
@@TheYorkshireBikeMechanic thank you! Are they all the same size?
Considering the ingress of dirt and discolouration of the grease, it must be an idea to replace any seals to the outside world in the motor?
Hi, Thanks for watching, these seals are not currently available
Super video! What grease do you use? Thank you. Jan
Hi, Thanks for watching and your comments. It depends where is going, We tend to use synthetic low temp grease but very sparingly.
good stuff! love from finland! Subscribed!
Thanks for the sub! and for watching
Hello Dave, execellent video, I have two questions for you: How many kilometer before change the bearings? Can you give me the bearings type?💪
Hi, dont do it, nightmare,
I have molykote pg 75 ( some white grease for big gears ) but i saw you use dark grey grease , what is the name of this grease please ? and 2nd question, which bearings press you have ?
Hi, the part you enquire about is not a part that is available, we use a lithium based moly grease, we use about 4 different presses on the motor
do you think , after a basic maintenance, drill a Grease port in apropriate location is a good idea ?
Hi, It would be very difficult because everything is sealed, bearings, drive shafts, gears, normally its just bearing wear and tear, such a lot of power and quite small bearings.
Can you do a Raking list which motor is the easyest for repairing?
This would be for me a buy reason.
Hi, thanks for watching and your comment, Brose, bosch, shimano
Ok so the lists of motor repairs and bearing doesn't mention what specific bearing sizes for the Shimano. Would it be possible for a specific list of bearing sizes so I can buy all of them somewhere before I tear into the motor ??
Hi Marc, I buy all my motor bearings here, www.ebikemotorcentre.com/product/motor-bearing-kit-for-shimano-e8000-part-no-pls00701/
Wow. Well done. Definitely a first. Is the 7000 motor the same do you know?
Hi Alex, thanks for watching, earlier motors are very difficult to work on as the circuit boards are soldered in place, no go I’m afraid.
very helpful hi i have the same motor mine at the moment makes an awful noise and is slipping like mad is this the normal cause of it slipping or would it be more than just bearings ps no error codes just noise and slipping any advice would be apreciated before i order the bearing kit
Hi, thanks for your question, excessive bearing noise is one thing but slipping under power is a completely different situation. Sadly they are a very difficult motor to service and very few will attempt it. Try contacting your Shimano Parnter to see if they can help.
@@TheYorkshireBikeMechanic thankyou for getting back to me much apreciated ps im going to order a new motor but i will go inside it once new motor is here is there anything inparticular to look for
Super Video von dir!! Welches Fett benutzt du? Kann man auch das Weiße von Bosch benutzen? Danke
Thank you
@@TheYorkshireBikeMechanic I heard that you have to be careful with the torque sensor. Because it may not work afterwards and it cannot be calibrated afterwards. Is that true? Can I also get spare parts from the engine from you?
Hi , I am not able to release the crank from the tork sensor , is ther le any slip or circlip to get it off ? I mean in your time 8:48 you get it off , but I could not
Hi, it should slide off the shaft complete but sometimes the bearings get stuck on the shaft, there is no easy way
Dave, do you think it’s worth wearing a grounding static electricity tether when working on this?
Hi, thanks for watching, It would do more good than harm Im sure
Hi Dave! Another great video. How can you tell if your bearings need changing?
Thx Steve.
Good question, when turning your cranks while the motor is of and the chain is off too. you will certainly feel and hear the rumbling/grating sound
@@TheYorkshireBikeMechanic
When I turn the cranks backwards I fell nothing very smooth. When I turn forward it’s smooth but I hear the gear engagement, is that normal or should it feel like when turning it backwards? and Thx for responding Dave!! by the way the motor is a Shimano e8000

There is no side to side play.
Hello ,
Thank you for this clear and precise video.
I have creaks when I force a little on the pedals whether the engine is running or stopped, but especially when the engine is hot. My Steps E8000 engine is from 2017 and has 8500Km. Shimano offers me a paid quote but I don't think Shimano agrees to take it under warranty...
This video is great because it will help me replace the bearings myself.
I couldn't find the link to buy the bearing kit on your site. Can you tell me where to find it?
Thanks again.
Hi Christine, Im pleased you found it useful. The bearing kit is £82.48 plus £5.00 postage. if you email me your paypal address I will send you back an invoice. my email is dkaye47@gmail.com

Hi, thanks for watching and your comments, in my view and from experience, no but others might say otherwise
Hi Dave, Im from the Philippines. I have a Ducati ebike model tk01. Can I ask you a favor if you can help me because my shimano EP8 motor engine is noisy/ rattle. What will you suggest?
Hi Ian, Thanks for watching and your comments, If it's less than 2 years old book it in with your shimano dealer, if its over 2 years, telephone your local shimano dealer, it could be that they will look at it under the our of warranty scheme.
very detailed
Hi, thanks for watching and your comment.
Hello Dave,
Could you please tell the Numbers or the dimensions of those bearings that you replaced.
Thanks to your great video, I want to replace the bearings in a Steps8000 motor.
It would help a lot to have the bearings before hand, so it is possible to disassemble and assemble in one session.
Thank you very much in advance from Germany.

Hi, Thanks for watching and your comments, the best way is to buy a complete bearing kit first. the whole job can be done in an afternoon, It's not an easy job and damage can be done without you knowing, my advice is dont do it.
@@TheYorkshireBikeMechanic Where can I buy the kit? I am a bike mechanic for 30 years. But where is the baring kit sold?

Sorry one more thing, my motor (e8000) turns fine in the direction of peddling, but feels quite stiff to pedal backwards, I removed the crank arms and was unable to rotate bottom bracket anti-clockwise.. any thoughts?… thanks in advance
Hi, Thank you for watching and your comments, sorry, tricky one to comment on as it could be a few things, best check it checked out.
E bike motors seem to be very difficult to work on . maybe it would be better to buy a new motor ?
i have a Nox xc mtb with the Sachs rs motor , which is fantastic . however the company won't even allow their handlers to work on them . the motors have to be returned to the factory and a replacement is given . don't know if this is a good or bad thing .
Hi, Thanks for watching, bosch and shimano are the same, all faulty motors go back and are not worked on in this country that I know of
Hi, can you please help? I have a bike I am servicing for a friend he has the e7000 with, I suspect bearing noise. Can this be done to that motor?
Hi thanks for watching. Sorry, the e7000 is not serviceable, the electronic boards are soldered in place and can not be removed without damage.
Great video, just out of curiosity do you have any idea how many miles that motor had done ? keep rolling with these fantastic video's. Thank you for sharing.

Hi. Do you have code item engine cover Dx whit logo Shimano? I search on-line but no find! 🤔
Not available at all, sorry
Hi Dave, just viewed this and have a question. On both this, the EP801 and other motors, are there any seals on the housing where the main driveshaft enters/exits the motor? If there are and you can't get replacements, then would it be worth replacing the bearings as you'll not be able to keep the crap out due to the seals being shot?
Hi, im not sure because I stopped opening up shimano motors a while ago, whilst bearings are available any seals are not, unless performance line bearings have has some made.
@@TheYorkshireBikeMechanic Thank you. I was asking out of general interest as I had been looking to get a Santa Cruz with the EP8, but the new Nicolai MGU has just been released and I think my money will be headed in that direction.
Gonna do my own bearings, what gear grease should I use ??
Hi Adam, tricky one to advise on as there are so many out there. We use Bosch genuine grease on all Bosch motors
Grinding noise, then followed up with no noise and noticable loss of power as well as feeling the crank having more drag when pedaling. NO ERROR message. Likely faulty bearings? 8500km in all weather in 5.5 years
Took it apart yesterday, looks like the big bearing on the right crank side is shot. Need the Shimano tool to remove that side
Hi, thank you for watching and your comments, be careful, so easy to damage
@@TheYorkshireBikeMechanic motor already apart mate, no turning back now :)
Good news, the big ball bearing on the chain side had completely blown up. Replaced all the bearings, cleaned and lubed. Back togeather now and working. Thanks a lot #The Yorkshire Bike Mechanic, I would not have been able to do it without your video.
On the Plus side I now also have a new E8000 on hand, as I pulled the trigger on one when I was doubting my ability
unfortunately my motor didn't feel much better after the bearing replacement. It lasted for a few weeks and then it went stff again, i fear that the crank axle is bent.
Bought a used motor, worked fine but soon I started to get the "duck" quack when under load on that motor also (3330km)...
What grease do you recommend? I wanted to lube up the gears between the motor and crank.
nice, but do you haven't any little shim left 7:50 that you didn't put back on the shaft? 30:15 😅
Hi, Thanks for watching, well spotted. I noticed when cleaning up after that I had a spare shim in my magnet tray. I have to take the cover off to bob it back on, doh
Great video! I want to overhaul a Shimano DU-E6002, can’t find a replacement set on performance line bearings. Do you have advice or part drawing/numbers?
Hi, thanks for watching, I could be wrong but I don’t think that motor is repairable, think the circuit boards are soldered in.
@@TheYorkshireBikeMechanic correct it is soldered in but there should be enough play to solder when installing so also for removing? Are any parts numbers written on the bearings from the Shimano motors you overhaul?
Hi E.A.D. Im overhauling my E6002 aswell. My bearing on the bottom of the black plastic gear is broken. Can you help me and tell me the type/size of these particular bearing? Would be nice.
@@alexanderrachinger4084 unfortunately I have to disappoint you, I have the same issues with unknown part numbers… how have been able remove the motherboard since it is soldered with 5 wires…? Without removing the motherboard I can’t see an option to remove the bearings and gears, do you?
@@e.a.d.4207 Ok. Ty for your help anyway. I clipped it and will solder IT after the repair. Good luck and best regards
i watched this like a crimi, thx a lot°!
Glad it helped
Probably oil Is better for the lubrication, and It we want we can improve the Gear box with two cups for replace It. The only big problem Is find the right oil for gears wheels and electronics parts.
So informative . I have to make an animation video of this video
Hi, Thanks for watching and your comments, I would love to see that.
Does Vaseline have to be checked at 1500 km?
or is it enough to change the bearings?
Hi, what do you mean by vaseline ?
@@TheYorkshireBikeMechanic I wanted to ask if you have to change Vaseline once every 2 years or every 2000 km? or what is the factory holds forever?
Good stuff. It's ridiculous Shimano won't sell the torque sensor separately..
Hi, Shimano don't sell any part of the internals from the motors they produce i'm afraid, they are not designed to be opened by anyone other than shimano.
I need a new torque sensor too, have you been able to find one?
@@alextheodossiou9635 no unfortunately not.
Do you know if the mounting holes are the same as the e5000?
Hi, thanks for watching, I don't believe they are
hei!! kan you also du the shimano EP8? thanks!!
Hi, I dont do ep8s, sorry
Hi Dave, snapped a Di2 rear derailleur need to replace the cable to a E8000. Does the motor need to be dropped?
It depends when the wire entry is at the back of the motor, have you got a photo of where the cable entry is?
Sadly can't post a pic in reply. It exits on the right side on the top of the motor frame housing. Looks like the wire goes over the top of the motor. Can't remove it by pulling so guess dropping the motor down is the only way.
@@LetRippr Hi, if thats the entry then its more likely to run over the top of the motor so yes looks like it's going to need to come out, turn the bike upside down you find it much easier.
@@TheYorkshireBikeMechanic thanks for the info, very helpful
So what is the difficult part, just due care and procedure.
Hi, thanks for watching, no jerking movements, super preparation of the process
awesome video, btw you forgot the shim from 7:54 to installed in minute 31:19 that so bad
thanks for watching and your comments, yes I did, well spotted. I put it back in when I discovered it spare,
Hi. Why don't you show how you mount the bearings 🔨😉
Hi Dave does the same apply to the Shimano steps e7000
Hi Alex, Thanks for watching, afraid not, the 7000 is difficult id not impossible to ovarhaul due to the circuit boards being in the way.
@@TheYorkshireBikeMechanic great thanks for the info! My E7000 just broke I suspect the plastic gear is broken. Does the e8000 have plastic gears? It's hard to tell from here they look black steel 🤣
