Followup.................after some preventive maintenance and parts, the tractor is humming........still no luck with the hydraulics.

I did a visual inspection with the side plate removed and the engine running and there were no visible leaks.

I shut the engine off, stuck the hand in the oil and it was painfully apparent that the control fork was not attached to the control valve..........or is it supposed to be attached?? Would this cause the lift not to work?? I found what looked like a shear key of some sort in the bottom of the compartment real close to the bottom of the control fork. Is this the missing 'link'? Thanks all!

There is no "shear key" that I am aware of. The pump is driven by six splines on the pto shaft and its' power comes thru a coupling and thence from the transmission.
The control valve has a "T" shaped stem that fits between the arms so on the control fork. The ends of the "T" fit in the sockets of the control fork. Can you find the contol valve stem? Pulling it back lowers the hitch and pushing it forward raises the lift. This is why your lift is not working. If the "T" shaped handles is still attched to the control valve you need to slip it back in the sockets for the lift to work. Before you do that, pull and push on the on the "T" and see if the valve moves back and forth. It only moves a little ways maybe an inch. If it moves freely it's not stuck.

From what I can tell by just feeling around, the 'T'shaped handle is still attached to the control fork and not the valve. The valve moves freely and again, judging by feel, there appears to be a spring on the end of the valve.

Shear key was the incorrect term...............looks more like a cotter pin that holds the valve to the 'T' handle............

What you found on the bottom is probably the clip the holds the crossbar of the "T" to the valve stem. You'll need to get the cross bar attached to the valve stem and get the clip back on. You are correct about the spring.It goes over the stem an fits between the valve body and the "T" cross bar.

See the image that I have attached.........it appears that I could access the control valve from the bottom drain. What do you think?

i think i'd drain the oil, snatch the pto shaft out, buy the 2 new gaskets I needed and make sure it was put together right.. probably take 5 minutes to drain, and 15 minutes to snatch t he shaft and drop the pump on a floor jack.. 10 minutes to reattach t piece, and clean old gasket off, 5 minutes to put pump back up with new gasket, bolt in, 1 minute to slip pto back in with new gasket, then 1 minute to re-attach fork to T.

or you can drain and work thru the drain port and a side cover and try it.. might work.. if you can see it and actually manupulate your tool in that space.

Okay.......bordering on going crazy. Got the control valve issue squared away, filled with fluids, and still having the same issue. There are NO visible leaks when the tractor is running and PTO engaged.

I did notice though that there is not a whole lot of movement on the control valve when the lift lever is moved. Is there an adjustment that I should check?? I think that I am getting close!

 

[bford]

One other thought..........does the draft control spring have anything to do with the arms rising by themselves with no load? After I finished re-attaching the control valve to the control fork last night, I hooked the tractor up to my box blade, moved the lever to the up position and nothing. I had the right panel removed to see if I could see any leaks. Nothing. In an earlier post, I mentioned that the control valve does not seem to be moving a whole lot. Can this be adjusted?

 

[Soundguy]

it won't move alot.. but some.. maybee 1/2" total.

how much trvel are you seeing.

did you manualy help it a bit to see if it moved smoothly?
