Farmall M hydraulics

Postby MWZad » Fri Feb 24, 2017 6:40 am

Hello guys. First off I was to say, great forum with a lot of good advice. I have a 1951 farmall m with live hydraulics and two way valve plumbed in. So I was able to play around with the tractor quick when I got home tonight. I held the liftall lever all the way back and clipped into position with the clutch pedal up. I moved the Christmas tree valve lever forward and back and I would only get 1 function, either lift up no down. Then when I switched the couplers at the rear of the tractor I would get pressure down with no lift up. If I released the liftall lever from the holding clip and put it to the natural position and moved the control rod on the Christmas tree valve it would still only do the same function. I am getting long winded but basically I am trying to say it would not matter in my situation if the liftall control was pulled all the way back and locked into position. I have been told that the suction line needs to be moved to the bottom of the belly pump vs be mounted high in the side like it currently is. And to change out the 30w in the hydraulic system to regular hydraulic fluid. Does that make any sense to anyone?

Someone over on yesterday's tractors has the same issue. Turned out to be the christmas tree valve was jammed and wouldn't move in one direction.

That was probably you, right?
