Could air cause this issue???

Might just be me, but I get "invalid link attachment" when trying to open that last one

Not just you.

Here is the picture that would not come up...

Kind of looks like a QC that is not plugged all the way on doesn't it?

What it looks like to me is a typical ORFS connection...but what is interesting is while the connection in the picture is rigid...there is some free movement at the other end (where I can just barely see) appears to be a Tee (previously mentioned)...this is the interesting part...the movement is such that it would surely be leaking if pressure was not preventing it when the machine is running...but this is the same line that was originally connected to the Tank/OUT port on the original single spool valve...

For the record...before I ever did anything I marked the line going into the Pressure side of the original valve...(there were only a pressure and a "tank" line...the working ports were deadheaded with QD's)

...After marking and then removing the two lines to the valve I positively confirmed that with the spool centered air passed freely from the P to the T ports...so I assumed this was a typical single spool OC valve...(...what they say about the word "assume"...!)

At any rate after what I've seen...I do not think that the "original" valve is typical...!...I think if I would have had/tried a typical OC single spool the same thing would happen...

With the low temps and lousy weather coming...I may have time to call the dealer and talk to a specialist that is familiar with all the auxiliary circuits etc...and possibly send me some documentation...they have been more than helpful in the past...
