Pat,

I know there were a lot of different hydraulic systems used over the years.  Below it a picture of our 1993 U240.  The aluminum block on the passenger's side frame rail (yes with optional, owner added pressure gauge) allows for total PSI adjustment.

Yes, Brett that looks like my stuff.  I do notice in the picture that the allen head screw is out a long ways.  Mine is all the way in!!  I still have the slow fan speed problem and I am working on it again.  I need a better drawing of the system.  I have 7-8 hoses connecting 5 components(reservoir, pump, Star Controller, HI/LOW solenoid value, fans).  No one knows about all that stuff and how it should work.  Can you find anything?

Thanks in advance Brett,
Pat,

Sorry, your system is different than the 1993 U240 original or what Foretravel sent when my pump "puked" at Fort Davis State Park.

Also, the 1993 was a single large fan, you have two smaller ones.

Have you tried getting info from either Foretravel or MOT.  May be a good idea to send pictures of each component.

BTW, that is a CAP on the adjustment allen screw that controls system pressure.  You have to remove the cap to access the allen screw with its lock nut.

When I first installed the new system (on the frozen ground in Alpine, TX), the fan did not turn.  I was devastated. A quick visit with the local hydraulic shop (lots of hydraulic farm/ranch equipment out there) said to go adjust the pressure regulator.  Also suggested adding the "T" and pressure gauge to eliminate guessing.  System worked just fine for the next 100,000 miles, and likely still works well today.

I just finished the electrical solenoid to put the fans on high speed according
to Scotts idea. Having just putting in a Seelevel system the select slot for the
different applications for the Javelina I used for the switch for the new fan
controller. The switch I used lights up when it's on. I will take pictures on the
instal soon.

So i really like the ability to manually turn them on prior to shut down. Everything clips the top 15 degrees off. Still planning on a 3 minute timer to extend actuation by retarder and brakes
