I've had my Hyd pump apart three times. evry time I put it back it will lift the loader up and then I put the loader down it won't go up again. the pump works good. I put new piston springs and a control valve spring in it. this last time I found the pin in the drawbar lockout lever was broken. so I changed it. same thing. If I take the drawbar control section off don't change anything and reinstall it then it works one time and stops again. Any ideas whats wrong?

Dave is your fluid level full, it will take a couple extra qts of hyd fluid to run a loader on the ca. Sometimes the balls can get out of round and will not seal properly, agco still sells them really cheap. Ron

The fluid is full and the check balls are perfect. The hand lever dosen't feel rigtht after I cycle it from up to down. I'm taking the Draw bar controll off again today to see Why its not operating the control valve.
