950 jumping hydraulics

Hi all, I have a question about a 950 tractor with a 75 loader. A friend had lent me this tractor with the provision that I fix it for him.

The problem is that the hydraulics are not smooth. When using the loader, lift arms or power steering they kind of start/stop with a jerking motion. If if put my hand on the line between the loader control and the pressure control block that goes to the power steering I can feel a pulsing vibration.

The unit had lots of water in the hydraulic fluid which I drained out. I blew out all the loader lines and drained the cylinders before putting in new fluid.

Any ideas? Is there a hydraulic schematic available?

Thanks
Jon
