    Hi, I have found where the noise comes from, but still waiting from feedback of the seller. The noise comes from the gear in orange, I believe there is some slack that should not be present causing the rattle. You can see this in this video...

    thank you very much for your reply, If I rotate backwards it does not make any noise, only when I rotate forward, and it makes noise even without power nor chain. According to the video you sent It might be this gear. Is it controlled by the blue gear bearing ?
