T30 Hydraulics Help!!

I aquired a T30 from my father in laws estate that had been in the barn for 10 years and not run. With the normal carb cleaning, it runs fine. Problem is the lift will not work after sitting for 10 years. It is full of rear end oil and with the PTO running, nothing happens. Somebody told me the valve might have stuck. I removed the side plate on the right side (carb side of tractor) and followed the fork down into the oil but I am not sure what I am feeling of. Does the valve run longways with the tractor next to the right side of the case? I though I could get movement there. The fork does not seen to have much actual movement other than the resistance of the spring.
I am sure it was working when he parked it. Can anyone help me with locating that valve or any other ideas?? Thanks

Buddy it sounds like the forks to the control valve are not moving far enough to pull the control valve closed to raise the lift arms. The control valve is located in the center rear of the punp and at the end of the forks. The control valve has an override spring for opening the valve to dump the pressure but is positive pull to close the valve. The valve closes to raise the arms toward the rear of the tractor. The high pressure relief valve is located just above the control valve. On the TO-30 there is a control valve oscillator that rotates the valve back and forth to prevent the valve from sticking. The TE-20 and TO-20 does not have the oscillator. If I can help send me an email. Dave

TE20 series does have an oscillator from serial number 134,001 (1950)

I'm thinking you mean this problem is occuring on a TO-30. There is a lever on the left side of the transmission housing underneath the seat. Make sure that it is in rear position to engage the pump and the PTO. Just because the PTO shaft moves doesn't mean it is connected. I've seen them turn due to the oil moving around. If it isn't in the rear position, move it there and then move the lift lever aft and see if the lift works.
Since you have the access cover off, move the lift lever completely back and see if there is a lot of leakage from the piston/cylinder which is mounted under the cover. (DO NOT PUT YOUR HANDS IN TO THE ACCESS PORT WHEN THE ENGINE IS RUNNING!)If you see a lot of fluid drippping from the piston/cylinder region, you probably have bad seals/rings on the piston. You could also have a stuck open relief valve.In that case there ould be oil blowing out of it but I'm not sure where it's located. Someone more knowledgeable than I regarding the hydraulic system might be able to help you further.

Jerry, the relief valve is located immediately above the control valve except for very late model tractor tractors, after serial number 429,001 when they moved it to the top cover front left corner. Not often the relief valve sticks open, if the hydraulics are used correctly the valve doesn't discharge that often and the very high spring loading will usually keeps it shut. (But then again how many are used correctly?)

Thanks John. I'm not too terribly knowledgeable about the specifics of the Ferguson hydraulic system but my engineering background helps me to understand the genneralities. I suppose if I had problems with the hydraulics on my TO-30, I'd know a lot more. Knock on wood, I haven't had any yet.
