I installed this kit myself. I'm not engineer, I am law and administration department graduate and... this replace was piece of 🍰. Instruction follow you step by step. From video looks like very difficult but in reality it is EASY
Excellent videos and I will certainly use your services when needed. A couple of questions. 1. What is the white grease used on the gears both steel and nylon/plastic. Is it synthetic lithium of some sort? 2. What's is the big deal with not touching the freewheel? Ive seen the same approach in other videos? 3. (my bonus question) Do you think the use of jetwash is to 'blame' for the water ingress and bearing failures? Once again, great instructive videos and bookmarked your website for future use.
You are correct Martin, the Bosch drive grease is a lithium based grease used in the automotive industry but unavailable commertialy. As for number 2, not touching the freewheel is just a sure way of not introducing any grit ot dirt into the clutch bearing. Just remember if you touch it the bearing surface make sure its clean. Number 3, Pressure washers are definitely to blame in some cases, but fording rivers, constant deep puddles, hosing the crank regularly, carrying the bike on a rear mounted car/van rack in the wet without a motor cover, washing the bike on its side etc. etc.
Hello Thanks for the very good video - One problem I haven't answered yet, nowhere: - The part at 4:06 , which is in the freewheel, has hyper-sensitive surfaces, everywhere it is warned not to touch them and in the assembly instructions for the service kit it also says " do not clean"... But what happens if I have wiped it with a clean, lint-free cloth? Possibly soaked with Isoprop to get it nice and clean. The instructions with the "do not clean" only came later with the service kit... Background: Greasing the gears myself and wiping the freewheels dry have only ever brought brief improvements. Now I have the service kit here, still unused, because I'm not sure whether I can the rocket-scientific-hyper-sensitive-surface has not been ruined somehow... If anyone has any experience or ideas about how dangerous this really is beyond "just try it out", I would be very pleased to receive answers. Thanks and best regards
Don't worry, you will be fine. The bit to worry about is what grease to use, because that large roller clutch bearing relies on friction to stop it slipping. This friction is gained through the grease, so using high slip, high pressure greases here will not go well. To be honest, if you use it sparingly, you can add a very thin coat of Bosch Drive Unit grease to the surface of the freewheel gear and then slide it into the clutch bearing. If you are fitting a new Bosch service kit, or a new bearing from me, these are both pre-greased and will work perfectly.
Hi - I received the plus version of this kit from you yesterday (the day I after I ordered it). Using this video I fitted it and the left hand crank bearing today and now my bike is like new. Thanks - great customer service and really good value kit 😁😁.
This is always easier to answer with pictures, you should find the answer to this question here: www.ebikemotorcentre.com/frequently-asked-questions-answers/#Bosch-Motor-Questions
Very good videos, im in Ecuador in South America , I have a bsch performance line cx from a Mustache 2018 with the electronic card of the drive unit broken, maybe you can give some lights of where to buy or if you have a second hand that may be available will be grate as well
The PCB (printed circuit board / "electronic card") is not available as a spare part. It is also programmed to the angle sensor on the electric motor, so the PCB and the electric motors armature have to be changed as one piece. What is your bike doing exactly? Does it turn on? Any codes? When does the code appear exactly? When you first turn on or when you start to pedal?
my motor is quite new....only year old and not lot of miles but since I rode on the wet sand at low tide with salted and sand water going everywhre, it sstarted to squeak at every revolution? i am not it only need cleaning and a bit of lub, any idea?
Where is the squeak coming from? It is unusual for a bearing to squeak, they normally sound rough and rumble / grumble. Is it a pedal maybe? I would remove the chain from the front sprocket and turn the pedals by hand. You should get a better idea if there is any permanent damage or nasty noises. Please email us if you need to discuss this further.
Hi, is there any reason why you don't put grease in the flat surface of the freewheel? another question: could be used a teflon based grease instead of the bosch grease? thanks for your videos!
This surface is used for the clutch bearing to grip to. The clutch bearing is greased with its own low pressure grease, so to add Bosch motor grease to this can cause slippage. We have taken Bosch motors apart with 60,000+ Miles (96,560Km), the grease has been perfect and all gears showed very little sign of wear. The other issue can be, any Teflon based grease reaching any clutch bearing will cause failure and this will happen quite quickly with the small clutch bearing. I hope this answers your questions.
So is the wrench symbol on my computer display for Bosch a dummy indicator or does it really mean something? The Bosch manual was of no help. I asked the Trek shop guys- they seamed clueless like they never dealt with that before. I've always noticed a noise on my bosch performance line cx, last couple rides it has become rather loud. Sounds like the main bearing according to your videos. Only in the easier gears on the back. Not in the mid to difficult gears.
If the shop or factory has set your motor service interval, this "service" spanner (wrench) will be shown. Once the service is done, the dealer should put your bike on diagnostics and reset the mileage or disable the spanner by setting the mileage to zero. (This service does not require the motor to be opened, it's just check the bolts, wire plugs etc.)
Apart from the needle bearings can all the bearings be upgraded to sealed ceramic bearings if the sizes can be matched ? Also is it mainly the bearings failing than the electronics/motor failing ? Can the circuit boards be ultrasonic cleaned in the event of water ingress on the board? Also what material is the free wheeling gear shaft made of and is it a press fit gear on the free wheel shaft/tube ?? I'm new to ebikes and I have a mechanical background and I mainly repair and restore motorbikes and their engines etc but at some point I'll be servicing the bosch gen 3 motor in my e bike .. Great vid, thanks 👍👍
Several sizes are bespoke to Bosch, so a size match would not be possible. Fitting ceramic bearings in this application would be a wast of money though. It is not the bearings that are the issue, it is the water or dust. The circuit boards can be ultrasonically cleaned, but bit would mean de soldering them from the electric motor (not quite as easy as it sounds). Also, if you are doing this because of water ingress, it is usually too late and board components will already have failed. On the Gen 2 it's steel and one piece (Gen 3 is stainless and one piece). If you decide to have a go, keep things clean. We see so many motors where contamination has been left inside. There is no oil or filter, so what ever you put or leave in the motor will be trapped in there doing damage for the rest of its short life.
Hi! My bike has hit a rock on the left pedal, now it works with no noise but pedal backward is very hard, no cracked bearing noise but very hard, do you think the service kit contain the bearing involved? What is the bearing involved?
Hi, This probably won't be a bearing issue. You need to strip the crankshaft out and ensure all the bearings are still set at the right depth and check the transfer gear cage. This is the aluminium fitting that supports the two transfer gears that take the drive from the freewheel gear to the main crankshaft drive gear. This is not included in a Bosch service kit.
Yes, if your motor is still under warranty it will probably be replaced. If they clear the code and it does not reappear then they may just send you away again? I can't tell because it can change from dealer to dealer.
@@Ebikemotorcentre the shop just said I have crushed 1 pawl on free hub,u think that’s why it’s throwing up error 500 or they just trying to squeeze money ?
Hi Jan, Yes, we repair motors from all over the world and it is always cheaper than buying a new motor. Contact me through our site www.performancelinebearings.com
I need help my performance line cx motor is loosing power only for a second then it normal for about 3 seconds then it looses power again if I’m riding at the same speed for 10 minutes the motor keeps going on and off all the time the lcd screen is normal can anyone one help me it’s driving me crazy 👍
@@roccobulldog9876 Doesn't help me much I'm afraid. Email me a picture to enquiries@performancelinebearings.com Your motor should still be under warranty isn't it?
Hello, I will join the club of the noisy gears... :-( I have a Performance Line Cx, with +-14000km. The noise i hear is a beeping noise ("tsirping" like a little bird) when i turn the chain sprocket in clockwise direction. I also feel some "harder" resistance at some positions. Is this kit suitable for my problem? Thank you for these excellent tutorials. manu
Hi Manu, Without looking at what is going on inside your motor it is hard to tell if this kit is all you need? On our website you will find the Bosch Performance Line service kit + This plus kit contains all the other bearings and O-rings for the drive train and will probably be a better option in your case.
@@Ebikemotorcentre Hello, thank you for this quick reply. I am Belgian, and i saw you mentioned a belgium supplier (velolab) on your site. Can i buy the "Bosch motor service repair kit +" from them or should i get them from your shop? (www.performancelinebearings.com/product/bosch-motor-service-repair-kit/) Also, what is the price of a new motor? Velolab sells a new motor for 700€ but i need to exchange it with my used motor. Thank you.
Hi Manu, mine's making the same noise. What did you end up doing? Unfortunately, I'm in Perth, Australia, and nobody here has any experience fitting these kits.
@@carnthesharks I bought this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qunu7t8npus.html and will replace it myself. The problem with my motor gen2 cx, is the large bearing that got some water, and the one way bearings that after 25000km slip when in turbo mode…
Hi, I got Error 500 with Performance Line Gen2 and as I am out of warranty I would give it a try with the Service Kit. Do I need to delete the errorlog by some BOSCH service partner or would the installation of the kit solve these?
9.9 times out of 10, error code 500 is an electronics or component fault. The service kit may only help if you have error 500 once you first start pedalling. The code will not require clearing, it will just sit in the error memory, once you take the error away, the code will no longer show. Clearing the code on diagnostics will not usually unlock the motor.
@@Ebikemotorcentre I have the same issue as Marco S. Bike has 15000km on it, dealer tells me it is scrap and should be replaced. The shaft has a higher resistance than expected when rotating it. (dismounted motor). So i have hope that is caused by a bad bearing, causing the motor to always run in highest loaded condition. Could this trigger the error code 500 when it goes on for a longer time maybe?
@@kristofdb7139 Yes, it is possible that this could be causing your issue. Exactly when do you get the code come up? Is it when you first switch on, or when you first start pedaling or during a ride etc? 15000km for one of these motors is nothing provided it has been dry. Is your bike a Trek Powerfly by any chance?
@@Ebikemotorcentre Hi, thanks so much for your answer. My bike is a riese & muller, so not a trek. I opened up the motor and it looks pretty good inside, no water in ingress on first look. Gears also look fine. When turning on the bike, there is no error. I can use walk assist for as long as i like, going 15km/h. This makes me believe there isn't too serious of a problem. But as soon as i start pedalling, it will trigger the errorcode 500 and refuse to provide support. I think something might be off with the torque sensor?
Not really happy with the overall waterproof of the system. Giving your experience, how would you advice cleaning of an e-bike fitted with a bosch system ?
Same as any other ebike, fitted with any other system, use a cleaning product and soft brush, then just hose off with the sprinkler. Do not wash the bike on its side and don't hose directly at the sprocket or crank area. This would be the same for Yamaha, Brose, Impulse, Shimano ETC.
@@stug45 No benefit will be gained. The plate already has a bead of silicon fitted. If you were re using a cover plate and the bead of factory sealant was damaged, then yes, silicone sealant would do the job.
Hallo! I have a Bosch Motor active Line plus 2019 50Nm can you Upgrade to Performance Line 65Nm the Same Bike come 2020 with same Form but performance line with 65Nm
Yes, you can. Or you can fit the Performance Line CX 75Nm if you want. The screws, bolts and wiring is the same but you will need new crankarms for the pedals, motor covers and aluminium motor bracket (We normally have motors available and brackets etc. if you can't find them). Contact us through www.performancelinebearings.com
@@EbikemotorcentreThanks for your answer! the Performance Line is enough I think I saw they are the same gears but I don't know exactly what to change and where to find them I'm from Germany
@@Jannisvinios The CX has the same physical gearing. If you would like to email me I can tell you all you need to know, don't worry I won't try to sell you anything unless you actually want it.
Hi. I had an active line plus motor fail. Sent it to service agent, got returned, same problem. Fault 0x500332 Internal Drive Unit software error ⇒ no motor support came up. Bosch said it was probably due to water getting in and rejected the warranty (2 1/2 years old) I pulled it apart and found the needle clutch and large main bearing rusted and stuffed. Cleaned, replaced bearings but still coming up with fault. Bearing kits are not available from Bosch in NZ and they are not happy if you open them up to do the job even if they have rejected a warranty so they refused to help clear the codes or offer any help other than to buy a new motor. How do you get on with getting assistance from Bosch with regards to older motors outside warranty?
Hi Pete, I have a Bosch Performance Line CX, and a few days ago it began to make a noise, mostly on emtb o turbo mode but only at climbing.... Similar to a coffee grinder. How can I know the kind of bearings or kit I need to replace? Thanks a lot
The “coffee grinder” noise is usually the first sign that the main motor bearing is failing. As your bike is 2018, it should be covered under warranty. As your bearing has failed so soon, this normally points to an issue with water getting into the bearing? This maybe from a deep-water crossing, hosing/pressure washing the bike around the crank area etc. You can normally confirm if it is only the main motor bearing by removing the chain from the front sprocket and turning the pedals. You will hear the bearing while pedalling forward, when you pedal backwards, you are then listening to the crankshaft bearings. Either way, if this is something you want to fix yourself, I would leave the motor in the bike, remove the right hand crank arm and sprocket, remove any plastic motor covers and then remove the right-hand motor cover, you will then be able to see and feel all the bearings and ensure you get what you need. Or, you can send your motor to us for repair. I hope this answers your question?
@@Ebikemotorcentre hi Pete, thanks a lot for your fast reply. I live in venezuela and here most things are really difficult. Maybe I can send the motor to Germany but the expenses round-trip could be very high. My nephew is a very skilled engineer, he knows how to fix everything, he will come back from US this weekend, I told him already about this problem and I sent him your instructional videos... So I hope in a few days I will be able to send you some pics about and then you will be able to advise me what I need to buy... And then we will solve the shopping OK... Anyways I use to buy things by Amazon, then I have a kind of po box in Miami, and from there they send it to me in Venezuela, very fast....
This is for the Gen 2 Bosch motor. The part number 'BDU2xx' Stands for "Bosch Drive Unit 2". there is a lot of confusion out there that the Gen 3 was the black Performance Line CX but "CX" was never available in Gen 3, only Active Line, Active Line Plus and Performance Line. Nothing is currently available for the Gen 4 CX.
