Well, RickB was right on another point...

I would like to apologize to my fictitious mechanic since just
a few minutes ago, at my local Case dealer, I discovered that
Case did indeed switch all controls sometime between 1991 and
1995. They changed to a mirror-image control valve, swapped
the lines, and crossed the rods. The most recent parts manual
has the new stuff shown, but the most recent service manual
makes no mention of the fact. I had saved some money by buying
an older (new) parts manual figuring that any discrepencies
would show up in the service manual. Bad move...

The question is, why ? Why did Case see fit to change a design
which had been around forever ? If it was just to swap the
hand controls they could have just offered crossed rods. They
went through several different valves but they're all basically
the same. I really don't see what they gained.

I was concerned while changing things 'back' that everything
looked too well done. The rods showed no signs of having been
butchered, just a neat little dent in the crook of each bend.
The metal lines seemed more at home where they were, than where
I wanted to put them. But the real kicker, that I noticed
this morning and sent me scurrying to the Case dealer, was that
the relief valves for the bucket cylinders were not on the same
spool as in my manuals (and there's no way to move them).

So now I get to change everything back... I sure am getting to
know this machine ! Still haven't used it, but I guess in this
forum that may not be serious issue :-)
