Hello, I joined recently and am looking for some guidance.
I got what I thought was a great deal on a Cadtrac and the trailer it was on. There is a problem. After a short while the machine slows down until it won't move at all. the bucket remains operable. The 4 wheel drive doesn't work either. It does not have the newer set up that uses a foot operated valve for travel control. Every thing is controlled by joystick.
The tank temperature get up to about 165 degrees and the temp at the pump is 220 degrees. I wrote to cadplans and this is what he told me: "Usually the only thing that gets the oil that hot is an improperly plumbed power beyond valve.
If there is a power beyond (normally on the loader control valve) that port MUST be plumbed to return to the tank.

The improper thing to do is PLUG the power beyond port.

The other, less frequent mistake is to run the supply from the pump into the outlet of the valve.
then, the inlet of the valve is used as the return.

Good luck. " I am attaching an image of the control valve. what or where is the "power beyond valve and where does the supply line attach? thank you all so very much.
