Didnt run, so I tore the front of the motor apart

I just got a 2002 explorer with a 4.0l 4x2 that didnt run, so I tore the front of the motor apart to the timing chain which I thought there was only 1 timing chain but found three and the timing chain tension was broke, I have no idea how to set these chains back to the right timing now that I have the new tensioner could someone please tell me how to set these chains right, a picture or a diagram might help me if u have one

And maybe a explanation to go with it, theres a small chain at the very bottom then a bigger one connected to that one which connects to what I believe is the timing chain to the cam

Thanks!
