Super A hydraulic update.

First of all thanks to everyone that has been helping me out.
I had time to hook a test guage between the hydraulic manifold and the IH-1000 loader last night. With it hooked up no load on the loader the touch control lift arms made the pressure run 200-300 psi. if you ran the loader it would run 200-400 psi. If you ran the loader all the way up or tilted the bucket all the way down or all the way up till they wouldn't go anymore the gauge would peg out at 1000 psi. should I have more Psi through the whole range of motion? I asked my dad to test it with a load of dirt today since I didn't have time last night.
I do know that when the bucket has a scoop of dirt in it it will only lift 2' off the ground. The loader on my Farmall 100 has not problem picking up a full load of dirt heaping over the sides. I know something isn't right. Does these pressure sound about right?
Thanks

The system will only develop enough pressure to overcome the load. That is why you only see 200-400 PSI when moving things around with nothing attached. When the loader got all the way up, then the pump would develop full pressure because it's pushing against something, not just moving the empty bucket.

If you get the touch control blue ribbon service manual, it will describe attaching 300lbs of weight to the arm to test pressures.

Sounds like your pressures are just fine.

The stopping 2' off the ground sounds like a lack of oil to me. If the system is developing enough pressure to get 2' off the ground, it should keep going.

My guess at the problem: The touch control pulls oil in from the loader tank by siphon action. If there is an air bubble in the touch control block or the hose connecting it to the reservoir, it can't pull oil in from the loader tank, at least not enough to lift with something in the bucket. With nothing in the bucket, air is enough to lift the loader.

I had a problem with air in the system on on a loader that I installed on a Cub once. Never did get it figured out. The pump would make a loud "ZZZZING!" noise every little while.

Maybe there's a procedure in the 1000 loader manual for bleeding the air out of the touch control?

does the oil from the Loader tank go through the low pressure hose on the loader tank to the fill plug on the touch control? If this is where it gets the oil that might be my problem. I have been thinking about redoing that line. My other idea is to take a bucket full of dirt and lift it as high as it will go and then check to see if the touch control is empty. I think maybe you are right that it is running low on oil and not getting it from the loader tank. Do you know exactly how it gets oil from the loader tank to the touch control?

Good morning Chad,
It is not a lack of oil or the loader would not go all the way up empty. You are lacking pressure because of the relief setting on the loader valve. Either the loader valve relief has a problem, the setting is too low or the pump cannot develop enough pressure because it is worn out.
The loader quits going up loaded early because the leverage changes at the cylinder as it extends.
You need to find out what max pressure the loader should have and get a gauge that goes high enough to handle it.
If the spec pressure cannot be obtained, you need to find out why.
Matt is right, pressure readings are relative to resistance.
Remember, flow is speed or movement and pressure is power.
You are lacking power.
Good luck with it

I have a correct gauge to check pressure I know that it should only be max of 1100-1500 PSIG I have a 2000 PSIG gauge. I will do some more digging and try to let you know what I find out.
