1958 Ford Hydraulic lift problems

(quoted from post at 11:44:30 02/01/23) Bleed the pump.

One other thing, I noticed that the piston never leaves the far end of the cylinder. Today I am trying the screwdriver through the fill hole to move the linkage to see what happens. Any other ideas for me?

(quoted from post at 12:43:27 02/01/23) Okay, First let's define what you mean by
#s 4 and 5.
There are three oil compartments on those.
Transmission, hyd oil and rear end.
Did you drain and refill all 3
compartments?
Next, did you split the tractor or have the
pump or hyd manifold off?
Did the lift work before you changed oil?
Could you have bumped the manifold on a
stump or rock?
Those piston pumps can be a real pia to
bleed.
They will pump, spit and spurt oil and air,
sometimes for a looong time before they
fully prime.
Connect a hose to a barb on the pump and
run the other end to the oil fill on the
hydraulic reservoir. Run the tractor for 15
minutes or if you can, take it for a spin
for an hour. Lift and lower the 3 point as
you go.
Then remove the hose and put the plug back
in.

(quoted from post at 10:30:12 02/02/23) Re, your item #2. Pushing the Draft/Position control lever down & having the system lift arms rise, strongly suggest that the linkage is not adjusted properly and/or linkage is bent, worn, etc.
I will attempt to explain why the DRAFT/POSITION lever makes it lift. The two pictures of Draft/Posn linkage show it in Position control with spring NOT compressed & the other show it in Draft mode with the spring compressed. As you move lever into DRAFT mode the arm labeled "L" is pulled such as to toggle the mechanism to the position shown in yellow, thus compressing the spring. That is all normal, but another thing that happens during this movement is that the whole assembly tries to rotate about the pivot where the tag is attached. Once the toggle is completed/spring compressed, this latter "whole assy" rotation is relaxed. But before it is relaxed, this rotation (red arc arrow) pushes the draft mechanism to the left which moves the control arm toward the lift position. Now the control valve is moved to Lift position and you have lift.
Disclaimer: This drawing is for the 8N Ford, but it serves to explain what is happening with you tractor, as much is the same.

(quoted from post at 20:14:12 02/07/23) In one of your pictures, you have your letter "T" and above the T is a pin sticking up. I had an accident and broke the pin off. So I bonded the pin back in and I do not know exactly what the pin does. Hopefully, that will work???

When I hold the draft control lever down and work the touch control lever; then I get the arms raising and lowering. Should I have to hold the draft control lever down? Shouldn't it lock in place?

in is a guide to keep the plate from rotating out of position. Once the toggle (the plate in question) combined with the part that rotates against the plate, compressing the spring, I do believe the Draft position is set & held. If you are pushing Draft lever further than that, there is no point in it once the mechanism toggles..Still sounds like adjustments are not right.
