Can you please give us a little more information?
When you say the hydraulics at the outlets don’t work all the time are you referring to when it lifts or when it lowers an implement such as a disc?
I am having trouble with my 1370 at the present time when I go to lower a heavy implement such as a disc it sometimes stays in the raised position.
When I move the lever to lower it acts like the thing is stuck. But if I move the lever very slowly and allow the cylinder to bleed down I can lower the implement.
I’m convinced my problem is in the outlets themselves. The hydraulic outlets are worn out and the back flow pressure over-comes the spring in the outlet.
I have been looking for an outlet with #10 female O-ring fitting to replace it. So far all I can find are ½ pipe and #8 outlets. I guess I will be forced to pay CIH prices
