Ford 9n Hydraulic lift problem

Rob Heilman Hi, I just bought a Ford 9n from an auction so I do not know any of the background regarding this tractor. Currently the Hydraulic lift does not work at all. I have removed the inspection cover and everything moves when you move the lift lever and the piston does not appear to be stuck. The lift arms can be lifted manually and fall back to the ground with no resistance. The fluid appears to be new and I suspect was changed by the previous owner to see if this would solve the problem. I was going to rebuild the pump but wanted to see if there is anything else I should do to further my diagnose before doing this.

Thanks In advance

Bob G You do know that the PTO has to be turning before the pump will work. The pump is driven off of the PTO shaft. lever on left side by your heel is the PTO lever.
Good Luck

Bill Jones I had the same problem recently. I had just rebuilt he hydrolics on my 9n. New oil, overhauled the pump etc. After all that the 3-point would not work. After several days of thinking and considering pulling the pump it accured to me that the pump may be air locked. I pulled the side covers off and with the use of a 4-inch crecent wrench removed the upper plugs in the pump. Kind of messey, you know, putting your hand in all that oil. Well what do you know air starting bubbling slowly out of the pump. Put it all together and it worked. No were in the FO manual does it talk about bleeding the thing!
bernie bornick Turn pto on and the hydraulic arms come up with the lever down, even with the bush hog on the back????
mike oconnor my lift wont lift much weight had to reve the engine get it lift 2 cinder blocks the arms move freely with no resistence when tractor is of its had a lift kit put in before i bought it 2 yrs ago

Brian I have a 1940 9n, the hydraulics will not lift any weight at all, if you lift the arms and run the hydraulics up it will hold the arms up. I was just wondering where to start? I have checked the levels and they are good. Thank you for any help.
Werner Hi, I have a fiat 615 tractor and the hyrdaulic lift does not work. I replaced the pump and installed a new lift kit but it still won't work.

Any advice will be appreciated

Jeffrey Gilmour Hello, I have a fully restored 1944 2n. Everything has been working fine and I was in the middle of running a spring rake across my field, nothing to big or heavy and the 3pt stopped raising. When I removed the spring rake it works fine? I pulled the inspection plate and oil level is clear and good and everything seems to be in working order. When you try to raise 3pt with weight I notice some air bubbles form in the oil any ideas?
George Marrin The hydraulic lever on the right side of my 9n is stuck and I can not adjust the height of brush hog.
LeRoy Sanders I have recently aqquired a ford tractor 641 that has been left outside quite a while. The lift worked for a short time and then stopped lifting altogether. There was water in the oil. Drained the old oil and replaced it with a 134 hyd. oil as was recommended by the local dealer. Not sure of what to do from here. Thanks
Trace Lift will only lift about 50 lbs. I went to lift it in the winter and the blade was froze to the ground. The from of the tractor came up. I took the spud bar to the blade and broke it loose. Then the lift would not work. I opened the inspection plate on the right and saw oil shooting straight up from the center of the pump slightly right. So I dropped the pump out and replaced the safety valve and inspected the gaskets. They looked good. I put it all back with new fluid and still no lift. Now I have the entire pump apart looking for something?? I see a strange hole in the housing in the rear lower left corner. Looks like it is chipped out or maybe should not be there at all??? There is a channel from the outside of the pump housing leading to this mystery hole so maybe it should be there. Any one got any ideas?
