Is somewhere instructions how to uninstall and install main pedal shaft.
I'm going to make full service to my motor and change bearings etc.
Maybe you can look at youtube videos. I watch all of them and then played with my old motors, as I have currently 4 bicycles for all the family I have spare motors to use for spare parts, etc.
If you are going to make full service, you will then remove the torque sensor and so I suggest you to do a good calibration: https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki/How-to-calibrate-the-torque-sensor
I really hope we can improve the firmware in a way it will be able to use the full range of the torque sensor, including the no linear range and probably make a calibrated torque sensor to detect up to 60kg of force.
And please read that page about the torque sensor to avoid damage it, it is kind of fragile and you need to take careful when disassembling and assembling.
