Super C hydraulics won稚 work

[feleds]

We had a leak in the valve so we had the seal and boot replaced. When we put the valve back on, refilled the fluid, started up the tractor the lift control
Lever would not move the lift using either direction. I tried blessing the
System, we ran the tractor for awhile moving the lever up and down still doesn稚 work. We didn稚 touch the pump at the front of the engine. Any suggestions? I forgot how to add a picture

Yea I tried blessing but. I meant bleading

My son wanted me to add this is the hydraulic auxiliary control valve. We filled the resivour and took off a hose and started the tractor moved the lever and fluid pumped out a steady stream no air pockets. Then refilled the resivour

Sounds like you have an air lock in the Touch Control unit. To bleed it, move the 2 short levers on the center pedestal, that control the rocker arms on the TC unit. Move them at the same time. Move forward, then back, hesitating maybe 2-3 seconds at full forward, and full back. You should start seeing the rocker arms move. Keep moving levers back & forth, until rocker arms move from full front, to full back. Then you should have oil to the aux. valve.

There's been a couple of times over the years, I've had to nose the tractor downhill, enough to drop the nose a foot or so, to get oil to flow up to the pump. Since it was working before, this should fix the problem.

Thanks for your input I will use this information would a Super C repair manual be of help to this novice tractor guy and is it better illustrated than the owners manual?

A repair manual would most definitely help out. An I&T manual would be a good inexpensive start. They do lack a lot of information, as far as step by step instructions, and have a few illustrations throughout the book. They cover most repairs, but lack a lot if instructions how to go about it, for a newbie. But, they do have info on tune-up specs., fluid capacities, etc.

The OEM IH Blue Ribbon manuals are best, but, are in sections. Each one covers a specific section of the tractor. Engine, transmission, hydraulics, etc. Best place I've found them is on ebay. You can always make a saveable search, and ebay will notify you when one is up for sale.

Thanks appreciate your help Im a little more than a newbie but have alot to learn thanks again

I followed your advice by facing the tractor down hill. the 2 levers that level the fast hitch work very well but the main lever that raises the lift still does not. I went to blue ribbon manuals and ordered the manual on repairing the hydraulics so I will be studying up on that when it finally gets here. My son took off the filter and cleaned it. It was in good shape and not to dirty. I appreciate your help discovering the problem I am having. tractors by net is a great site I am so thankful it is available for me to access.

One more thing When we removed the valve to replace the seal and boot (didnt know how to go about it so I took it to a guy in my town that works on tractors and has a collection of 24 restored tractors) Anyway when we cleaned off the old gasket some of the grit dropped into the ports and my son blew it out with an air hose. he is concerned that he might have done some damage. He did lift the boot and the seal is still in place.

Does it still have the inline check valve on it. That would be the somewhat square block, just ahead of where the seat support/toolbox mounts to the top of the transmission. Two hoses from the Aux. valve go in to it, then two more hoses out of it, that go to the lift cylinder. If that check valve block is still there, that could be your problem too. It seems to be more of a problem lowering the draw bar, than raising, but, I've still had it be hesitant with raising it. They can get dirty, or corroded, and not function like they should. We took that block off of both of ours. Dad removed the one on his, back in the late 70's, and I took mine off about 15 years ago. No problem with either. I've seen more than several threads where guys have taken them off with no problems.

If I remember correctly, I don't think it's possible to put the Aux. gasket on upside down, the way it's formed, to block the ports. It's been 20 years since I've had mine off.

If the Touch Control arms are moving, then I'd think that part, and the pump are working properly. You should also have a pressurized flow to the Aux. valve at all times. Me, being me, would probably loosen the Aux. valve, pull the coil wire so it wouldn't start, then bump the starter a few times, to see if there is oil flow to that valve. That should tell you pretty quick, if it's the Touch Control unit, or beyond.

Also, I doubt it's the problem, but do check the relief plunger on the cylinder, if the draw bar is all the way down. There should be an ear mounted on the ram of the cylinder, that contacts that relief plunger, to keep it from dead heading against the pump, when lowered all the way. IF that plunger is stuck in, it will just circulate oil back to the valve, and you'll get no lift.
