Bernardo, this happens when someone posts, "I am converting a model" and leaves it at that. Even though we see that you are using MCX we actually wonder if you mean that you are using a magic wand. We have no idea technique, procedure; Christian, bless his heart, thinks, "what software could possibly convert a model, simply by virtue of activating it, as SAMM might and not by diligently applying a specific procedure, which is required with MCX."
Personally, I have a very specific guess about a slider and fix, but I'm still waiting for you to type at least as many words as I have.
Hi,
You need to go to the Animation Editor in MCX, check the lines that mention the gear, slide the animation slider in the Editor until the gear is down, and click the Fix Animations button. Then export.
