mg2361: Thanks. Here is the serial: 1T333EMVEE26477
We unplugged all of the solenoids on the control valve down by the battery (see pic) but no real change in fan speed. Where is (or which one) is the fan solenoid? There are 3. My manual only shows 1 so we must have something "special' on this. Unplugged all 3 harnesses. We started the skid and the fan doesn't even turn. When we "help it" with our hands it starts turning, but slowly. When we speed up the throttle is speeds up too, but not as fast as I think it should be. We've had this skid for 4 years, and we've just never paid attention.
Again, we unplugged everything the below picture and restarted it and no noticable change. [Also, there is a solenoid that sits on that peg that is not in the picture. We removed it to clean it.]
We also removed the hydrostatic control valve to inspect. Was hoping to find debris, but it looks fine. Removed a few of the plus (allen plugs) hoping to find debris, all looks fine.
One note, we are not using hygard (or the other one). We were in a pinch and had to run aw-46 or 68 hydro oil. My operator can't remember the thickness but it was new hydro oil. I dont thnk that should matter, but with my luck, it might. I think the jd hydo's are aw-46.
We also changed the hydro filter when we installed the new fan pump. I didn't cut open the filter but did dump it to see the oil. It looked fine.
Is there something (like a valve etc) at or prior to the fan pump (which is brand new) that should be cleaned/inspected? There is a lot going on at the actual fan and I want to make sure its cleaned.
I am starting to think this is an issue with debris in the system or wrong oil...maybe too thick.... I can't imagine the a non JD oil causing it to fail.
Today I am going to clean the screen that is at the hydro 'tank'. I am desparate so I'm leaving my email that is linked to my phone. Anyone with knowledge or special manuals etc, please email me: firstname.lastname@example.org
