This part is already faulty. The hub could not detect it. Lego has replaced with a new one. Thanks.
But I am curious. What has happened inside the motor. Can it be repaired by a non electronic man?
So, let's open it up.
There is no screw or any opening...
Then I need to be a little bit tough on this.
I used a knife and Philip screw driver.
So, that's it.
Well, if you think this 13 minute video is boring, please forgive me.
Thanks for watching.
