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?
