The hold valve was rebuilt also. When you adjust the linkage do you pull the big rod up just till you feel resistance or till you can't pull it any more?

When you rebuilt the pump did you rebuild the hold positiin valve too? My WD did the same thing until i rebuilt the valve. The rebuild kit was less than $20 from AGCO.

Do you have a book with the pump broken down piece by piece. If its put together right it should work. All the linkage has to be adjusted correctly from the pump to the quadrant also.
