All the comments really help - I wish I could review the archives all the way to the very beginning of the forum. These forums are full of valuable information. Not sure how to do that.
I will pull the plumbing off tomorrow and see if I can figure it out. I have the operators manual, but it doesn't go into any detail on this. The valve assembly for the loader is just a simple three valve assembly. One each for up, tilt, and a grapple.
Thanks all for steering me in the right direction.
