Hello, has anyone ever changed the motor bearings?
This is the list I found online, I have doubts about the torque sensor bearing, 22*42*10 60/22-10RS, it is not available on the market, has anyone disassembled it?
Rotor
15*32*8 16002 2Z
9*26*8 629 2RS
3rd Gear ("Peek")
12*28*7 16001 2RS...
If your M510 is version 2, you can set how much force and how long it takes to start the assistance.
You need the Bafang BESST interface and the Bafang BESSTPRO app.
Maybe after a long time you will have solved it, but probably your problem is the internal wiring of the motor.
Disconnect the controller connectors and use plenty of deoxidizer.
Usually the fault is the VCC PIN.
