Have pump all taken apart. Not to difficult found two springs on top that are a little bent up so I need those replaced Now where I need help. First the smallest plunger does not spring out tight against cam follower. Is this correct or does it need to be replaced? Also little washer type thing with the offset hole in the unloading valve assembly had to be tapped out with a hammer and punch. Is this correct? The control valves also need some assistance. One hit with a hammer I was able to push them rigth out. Any of these would give the problem of being able to lift and not lower? Besides the few bent springs and gaskets is there anything else I should be replace while I am this far? Or do I just take it to a dealer? Also is there away to test before putting back on the tractor? Thanks again to all for your help. Jamie

Jamie,
After you check out the hold position valve you may find that you have internal linkage or pump problems. Inside the pump there is a rack of sleeves and valves. There is also a spring washer, that after many moons of use, will disintergrate. Small pieces of this spring washer will lock up the sleeves and valves and can cause the type of problem you have described. You may not even find the pieces but you might have to carefully drive the stuck sleeves out of the valve body. When you reassemble this rack of valves, they should move freely in the bore and the valves should move freely inside the sleeves. You may have to use some very fine emery cloth in the bore.

Jamie, I would also replace all of the plunger springs and check to see if you have the spring washer I mentioned. It may have disintigrated and is what is causing your problem. Duey
