I now have the pump off the tractor. First find before I took pump off was the the ball in the hold position valve on top of pump was missing. Figured that was the proplem put back togeather and still only up that is why pump is off now. Four cam followers on back side of pump three toward front of tractor are larger plungers than the one at the rear of tractor. One at rear does not hold cam follower as far out as front three lots of slop there front three lots of spring pressure. Could this be the cause of my problem? When taking out all those valves is everything just going to fall all over? Any one who has taken these apart and have any helpful bits of information it would be great. Thanks Jamie

When you take it apart do it on a large clean table and keep all pieces in order and make sketches or notes of which way things go in or come out in relation to the valve body. A factory book is a great help, get one (reprint) from King's Books
