Hello, looks like you have a breakdown in communication between the position of the 3-point linkage, the quadrant lever and the pump control valve. Forgetting about your second cover for the moment; First of all check that the control valve lever works freely against the spring through it�s full working range. Next, make sure that the pump lever is correctly attached to the pump backplate by the popper button. With the engine �off�, observe what is happening. With the quadrant lever fully down, the pump lever should be leaning forward in the discharge position. Raise the quadrant lever to about halfway. The pump lever should move fully rear wards. Have an assistant lift the 3-point linkage slowly. As the linkage nears the selected position the pump lever should move to the near vertical neutral position. Raising the quadrant further will repeat the process. When you lower the W lever the cv lever will go forward into discharge. As your assistant lowers the 3-point the cv lever will return to the neutral position when it reaches the selected height. It would appear that the cam on the ram arm on the main hydraulic shaft is not telling the pump that it should be in neutral when the point of maximum lift is reached. There are several things that can cause or contribute to this. With the Draft lever lowered check for in/out movement at the top link attachment point. There should be no end float present. The assembly should be removed and the control spring checked to ensure that it is tight to turn by hand. There may be damage or wear in the position control spring frame within the cover which is preventing the vertical lever moving the pump into the neutral position when told to do so. Observe with the engine running this time. If the pump lever remains leaning rearwards at full lift then that is the area of the problem. It may be possible if you have enough thread to unscrew the knurled screw on the vertical lever just enough to move the pump into the neutral position at the selected Qw position. If this does not work I think the next step would be to remove the cover and carry out a full adjustment sequence but for that you will need the special setting tools. Let us know what you find.

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I�m handing him tools and he says, "give me that..." and I�ve already got it in his hand or "hand me that....."and I�ve got the portable light right where he needed it placed to see.
