When I first got the tractor it just barely would pick up anything. I took the cover off and had a constant stream coming down from the lift cylinder. I tore it apart and cleaned the sump and took the pump apart and checked everything and replaced all the gaskets. I measured the lift cylinder and it was on the high side of the clearances but still within spec according to the ferguson manual. I put a new set of agco rings on the piston and reassembled it and it was marginally better. So I took it apart and did the naa piston swap and that cured it....for a while...after you used it for a long time it got to where it wouldn"t pick my hay rake up all the way anymore. Now it"s has gotten to where it picks up and then leaks down then back up and just keeps cycling like that and I figure the oring is shot causing a massive leak which is causing the cycling.

The fact that the system is cycling like you say does not mean that there actually is a problem unless you can actually see a leak from the Lift Cylinder, it can be adjustment or wear that causes this. It is a natural reaction if the system drops, it is supposed to lift again, but it can also be caused by adjustment as well. But the deciding factor is whether there is a leak from the Lift Cylinder.When you work on hydraulics unless you are fully aware what you are doing it is often better to leave them alone, especially the Pump, taking it apart does not always reveal if there are problems, by taking it apart you can make matters worse. You should always find out the location of the problem first and repair the fault, then re-test the pressure again to see if all is OK. Sometimes when this happens it means that you need to re-assemble the system and then do the tests that should have been done originally so that you can repair it. Take the r/h side cover off and operate the lever, if there is oil leaking as before from the back end of the lift cylinder, then really you only have one option and that is to replace it. A leak anywhere on the system will cause the problem you have, as it is just a pressure loss.
Take off the L/h cover and check the high pressure pipe in the front right corner when it is under pressure (try to lift a 2 bottom plow)as these can split due to shock loads in transport. If there is no real amount of oil leaking on the Cylinder then you should adjust the Control Lever Quadrant to the correct setting..John(UK).fergusontractors@hotmil.com
