Did a little checking out of the hydraulics today. Started with the simple one. Hooked up an implement to the 3 point hitch and raised it up. Surprisingly it went all the way up. However, after a couple of tries moving the implement up and down, when I left the lever in the up position, the implement would rise to the top and then fall to the ground, only to rise to the top again and repeat the process until I lowered the control lever. So I'm thinking stuck valve in the pump or possible scored cylinder or blown cylinder rings?

Prior to raising the implement to fully raised position, I moved the top link to the lowest hole on the top link rocker and, when the implement was up, I did the three finger check on the main control spring. Shouldn't turn if implement raised. Never mind three fingers, I could spin it freely with one finger; my baby finger.

So I'm thinking tighten the draft control yoke and new draft control spring plate with pin?

Tomorrow I take off the side plates to get a look at the boiler room, LOL.
