A friend of mine has a Ford NAA. He asked me to look at the 3 pt hitch due to he said it wouldn't lift as much weight as it once did. Right now it won't even lift the arms (later he admited it was 5+ years ago he noticed this and hasn't used it much since) at all. When I started they were in the up position, but now I can't get anything. The oil was a white color and the book calls for an oil no longer listed. 2 different dealers told me to just use hy-trans. After changing the oil, still no difference, arms do not lift.
On the pump there is an adjusting screw that if I understand correctly turning in increases flow and lift. When I started this was almost out to the point it was touching the motor oil dip stick.
1) Will normal hydraulic tranmission oil be OK? What I took out was much thicker?
2) Where should I begin to test or check this over? Anyway to know for sure if the pump is pumping?
3) What oil should I put in the rear diff and the trans? 2 dealers say hy-trans is what they use, just seems thin vs what is there.
