Help with stretched Maya animations import

Hi guys,
I'm having a big problem with the import process of an animation from Maya to Unity.
Here we are a screen shot of the animation in maya:


and here it is the exported fbx animation in Unity


As you can see the leg in the animation in unity is kind of stretched.
Also the body mesh itself seems to stretch a little bit, but the leg is really evident.
the animation is set as generic due to the kind of character bones.

could be a problem with the translated bones of the animation?
Does unity support translation and scale of bones?

could be that I have to export the animation in a special way?
please let me know if you can help me, because i'm struggling with this.
Thanks!

 

Scaled bones most likely. Reset/freeze/zero the scale/transforms on all bones and re-export to Unity.
