What is this part?
 

I was taking out the right motor mount of my 2004 Acura MDX for a timing belt replacement and this part fell out to the ground and I have no idea where it goes. I've looked at all the videos and pictures i could find and no luck. Its solid steel. If anyone knows what it is I would appreciate the help.

Looks like a turny-weighty thing.
