It may have just gotten dirt or debris in the gear housing, so I am in the process of cleaning and regreasing the gears. I should be hearing back from lcrewse shortly for guidance on grease type. Then I will Put it back together and test it out.
As others have said, noise from the motor is not normal at all. Should be just about completely silent! Check the main thread for Kepler's experiences with noises and fixes. Maybe take the chain off first and make sure the noise is not elsewhere in the drive train if you haven't already done so. I understand that there are screws inside which sometimes need tightening. Don't be too worried - general experience seems to indicate the BBSxx is a reliable unit if not abused although it sounds to me as though assembly sometimes seems to be a bit lax.Slowrider wrote:Is this "normal" noise and am I being way to critical or should I be concerned. The kit is super easy to install and I can not see what I could have done wrong so I am a bit puzzeled about this.
Any advice for how to remove the rotor from the stator?Kepler wrote:Remove the rotor from the stator and measure the diameter of the non drive side bearing journal on the rotor. It should be exactly 8.00mm. Check it for wear. Also check if it has a small orange o ring like on the drive side journal.

No, it goes after the washer but without an O ring grove in the shaft, I think the O ring is not going to be of much use. The latest design rotor now has a grove for the O ring to locate in.teslanv wrote:I would assume the replacement o-ring should go between the two washers?
I am in the exact same predicament here :/ In fact, I haven't finished assembling my kit because i'm still waiting for my battery, but by simply spinning the chainring manually I can clearly hear the clicking sound. I was also surprised by how stiff the spinning motion is... is it supposed to be so stiff? I know the rotation of my previous chainring (pre-electric) was much smoother.Slowrider wrote: Did the motor you have come with this noise from new or did it develope over time ?
Do you think it is possible to assemble it wrong, I did not have a torqe wrech when thightening the two main nuts and I was thinking that this may lead to misalignment for internal bearings causing noise ?
I am really torn as what to do, my motor is new with 0 km's on it and it should not be nesecssary to breake it down to fix possible faults from factory!? But on the other side it took almost 7 weeks just to get this kit so I would imagne that sending it back for replacement is going to take a lot of time.
I was able to find this at an autoparts store near my house.Kepler wrote: In relation to lubricant, lots of options here but the main point is not to use a petroleum based grease. I use this one http://www.chainreactioncycles.com/it/i ... lsrc=aw.ds
You should be able to get it from most bike stores.
Hi Savvas, I was actually thinking the same as you regarding renaming the thread.samsavvas wrote:Hi Slowrider,Slowrider wrote:I appreciated feedback regarding this.
I'd like to make a suggestion. Howabout renaming this thread "BBSxx - fault finding and fixes" (or similar). That way some of the scattered stuff on this topic at the main BBS thread could all be brought together here (I'm presuming this is possible). This would reduce some of the chaos at the main thread and make fault-finding and fixing a bit easier for those encountering problems.
Just an idea...
And with regard to your request for a video of the noise from the BBSxx running without a chain - just think 'silence', or maybe a baby breathing... something like that anyway.
