In the end I put a thin washer under the C-Clip to reduce the axial play and I also replaced this bearing because it didn't spin as smoothly as the others, I lubricated everything well and for now, after 200 km, everything works as it did when it was new :)
I didn't notice any wear or debris, the gunk inside the black cog is hardened grease, I don't see any scraping marks on the bearing und axial play ist about 1mm.
The only thing is that my gear seems to be brass, not steel like yours, and it looks more worn than yours.
Thanks again, I'll take the my motor apart these days to see if there are any scratches like in your picture, I have some technical knowledge, so I'll try to solve it somehow :)
S13 thanks for the answer and it seemed to me from the sound that the problem is not in the bearings, the warranty has expired, unfortunately I don't have a donor motor, is there any possibility of repair?
Hello everyone, lately my e8000 has become louder and when after a few minutes of driving it warms up a bit under heavy load in trail and boost mode, a rather loud interrupted sound is heard (kweek-kweek).
Otherwise, when I turn off the motor and pedal under full load, absolutely nothing is...
