1973 ford 4500 utility p/s

[farmal]

Rebuilt cyl and valve. New pump and still no p/s steering

 

[Destroked 450]

Loose and worn linkage pins, pivot pin and bushings will create to much slop to properly shift the cylinder control valve
On mine the tapered pin mounting the cylinder to the pivot arm was worn egg shaped, we welded it up and resized it rather than paying $100 for a new one, we also replaced all of the clevis pins
Have someone rock the steering wheel back and forth to see if the link bar is moving the control valve in and out
