1983 Ford 1900 tractor hydraulics stopped working.

[BenYehuda]

Less than 50 hours of running time have gone by since I cleaned the filter and changed the oil. The hydraulics worked fine. Now it is down to no action when just the machine is just started. After letting it run for 15 minutes I get some response only while patiently holding a lever for a length of time. The outrigger lifted then nothing else worked. Again activating and holding a control for a long time suddenly one item responds then nothing again. Could it be the filter again starving the pump or could there be air in the system? The power steering also works very hard with delay action and hesitation. Why would it act like dead then suddenly one hydro item works and stops?

Thanks,

Nat

Lets he some more info.

Is there a backhoe? Where do its Hyds come from?

Have you done any pressure tests?

This Ford 1900 has a front loader and a backhoe. I don't know how to do pressure tests. The hydraulics worked with some hesitation about a month ago. Now suddenly everything has stopped so that the backhoe would not lift at all then it worked. Same with outriggers and the loader. The loader lifted a foot off the ground then would not go up any further. By the way, i think the pump makes a squeaking noise until the tractor warms up. It's really hard to hear it over the motor noise. Could the filter be preventing the fluid from reaching the pump and could air pockets have developed or could this really be a pump problem?

Lets try this again... where do the hyds come from.. does this have an external pump or the onboard tractor pump.

do you have the proper oil in the sump. Who was the president the last time you changed the filters?
