9N hydraulic issue troubleshoot?

On the 9N, the 3 point will not move. So far I have checked the fluid level. It is good. Next i drained the fluid to see if the H shaped linkage was attached to the T shaped control thing that comes out of the back of the pump. Its still on there also. Refilled the case and checked for air pocket by running it and PTO while watching through the side access plate hole, since i read it will bubble if there is. No bubbles. Read also to work the lever and see if fluid sprays from the top, cause that shows some type of seal or something out. No fluid spray. What are the next steps? Some quick add-on info, i had removed the top plate a couple weeks ago to replace a gasket, and didnt know the H shaped thingy was attached and hooked to anything. I read this could have damaged something when i pulled the plate up and it unclipped from the T, but idk what to check for that. I had just clipped it back on when i assembled it and it worked fine for a few weeks. Also, the H shaped thing does not move when i move the lever, it only moves slightly when the lever is at about 1" from the bottom of being down. I read to test the control valve somehow?? What is it, and how do I test that? Or what other tests would you do next?

Sounds to me that the control valve may be stuck or the spring that connects to the "H" thing is broken, weak or disconnected. It must be good and
strong to move the control valve. Especially if it may be stuck.

Reach down into the oil and manually move the control valve in and our with the engine running.

Second what Zane said.
Just be careful of the PTO shaft turning when
manually moving the control valve in and out.
I hope the bore for the control valve is good.
I admire the simplicity of the fork/tee single control
valve design.
If you want position control Zane can help.

Is it necessary for him to have the PTO engaged and turning for him to do what you suggested?

Yeaaa, im not to sure i wanna try that. lol With the H connected, the T will not move. It is very solid. Should i disconnect it and see if the T moves? Should it move disconnected or connected? If that checks out, then i need to pull the top plate and check the spring on the underside then?

If that is the case then by all means deal with it
without PTO running.
You already know it is stuck hard.
Remove the fork and take it from there.
FO-4 manual shows linkage diagram.
I can bet that the pin/spring in the center of the
control valve is bent.
That being said, if the valve is stuck in a position
that is in max extension out, then it is possible that
the bore needs attention.
I hope I am wrong.

Update, the tractor is alive again. I dont know how, but it works. I got a bar and pushed on the forks backward to see if it would finally budge. it made a loud click noise and they moved. so i decided to start it, and everything works. so i just put it back together and ran it. haha Something was stuck. if it doesnt keep working i guess ill know i didnt actually fix it haha

When my 8N's lift quit working I also heard a loud click that I couldn't figure out. When I removed the top cover I discovered that the dowel pin that rides on the came was worn and it slipped off the side of the cam. Maybe what you did pushed the pin back up on the cam cause that loud click and making it work again. I don't think I would count on it working very long again until it is repaired right.

Very possible. I think it will probably quit again also. If it does i think i'll just pull the top plate as well, because thats likely what it is. I cant think of much else it could be at this point, since the forks were stuck, so if it does i'll definitely check the pin thanks!

because thats likely what it is. " Not gonna be!! There is no cam pin with the 9N! :roll:

Sorry, I forgot the subject was a 9N with no position control.

I think its the pressure relief valve that is mounted on the back of the hydraulic pump itself. I had same problem, arms would not go up.
