Customer Question

I have am 684 international farm tractor. The lift hung in the up position and I had a mechanic work on it and now the lift will only raise about 5 inches. I put a pressure gage on the remote and have 900 pounds.

Will the lift hold it's position? Or does it leak down as soon as lever is released? Pressure is adequate.

Customer: replied 10 months ago.
it holds it's position but will only raise about 4 inches
Customer: replied 10 months ago.
I think the pressure should be about 1800 according to my book
Customer: replied 10 months ago.
What do I do to fix it
Expert:  Curtis B. replied 10 months ago.

That would be set pressure, but it takes very little pressure to raise the arms without load, and they should hold position. Is this 4-5 inches with no load? If it is with load, then the pump would be suspect.

Customer: replied 10 months ago.
It will raise the same height with or without load
Customer: replied 10 months ago.
The pump appears to be working good
Expert:  Curtis B. replied 10 months ago.

pump is not keeping the arms from lifting. What did the mechanic do? Does the engine load up? The cylinder in the three point is ok, if it holds the load. So it has to be the valve cutting off the flow to the cylinder.

Which valve

lift valve.

Is that the valve by the piston, if so, we have replaced that

OK< Have you gone through all the valves in the three point cover?

Customer: replied 10 months ago.
Where is the 3 point cover?
Expert:  Curtis B. replied 10 months ago.

The lift cover with the two lift arms.

Customer: replied 10 months ago.
Is it inside the transmission? Can you send a diagram?
Customer: replied 10 months ago.
I don't have my book, the mechanical has our book
Customer: replied 10 months ago.
The cushion valve has been replaced
Expert:  Curtis B. replied 10 months ago.

Cover has multiple valves and check balls. I don't have service manual to know which one does what.
