Hi, I just have a question. In the video with the Unimog trying to climb uphill using its winch, you hear a clicking sound meaning the white 24t clutch gear is disengaging. But the two clutch gears I got don't make a clicking sound when they disengage. The axle hole in the gear wheel just turns after a lot of force has been applied. Is this a new type of clutch gear or is something wrong with mines?
