3 point hitch problem 67 Ford 3000
|Dean Davis||I have a 1967 Ford 3000 Diesel Tractor - the 3 point hitch hydraulic lift does not work - I removed the lift cover and found that both suction and return line filter screens needed cleaning, the suction filter was really clogged with sludge. I visually inspected all accessable components and reassembled, installing new o-ring seals where indicated. The lift still doesn't work. I did a pump pressure test as prescribed by the manuel and pump pressure was above 2500 psi. Any ideas on what to check next??
|harry16||The most likely culprit is a stuck unloader valve.
|Harry16||If you pull the lift cover and find nothing wrong with the unloader valve, then there are other valves you can check. There's no point of yo-yoing the lift cover.
There is a check valve right beside the unloader valve that may be stuck. The draft/position control valve may not be working. Also check the lift piston seals.
