Water in the hydraulic fluid is very bad. When I was plowing in the spring, when the arms were actually as low as it would go and the tractor would start to loose traction, a slight lift of the position lever would bring the plow up, but then I would have to push down on the draft control lever to get the plow to go higher. Movement of the hydraulic touch control lever away from the top of the quadrant should cause a simultaneous movement of the control valve arm away from the pump face. Once I get the lift arm ram welded I will proceed with the jig. 2009-10-02 166108. "@type": "ImageObject", I'll hold off on that and try without first.

After yesterday I don't have a clue how I could get the ram arm out. When I was plowing in the spring, when the arms were actually as low as it would go and the tractor would start to loose traction, a slight lift of the position lever would bring the plow up, but then I would have to push down on the draft control lever to get the plow to go higher. Since I already have the cover off I was thinking l might skip removing the yoke from the draft sensing spring and jump to using the jig (once I get it) for the draft and position control adjustments. I have watched you rebuild video twice and find it would be a great help if I needed to rebuild. Go just a little too far and you will get several gallons of fluid in the face or running down your arm as you frantically try to thread the plug back in. This means it works better as a year-round fluid. So, you guilted me into starting with step one. This step-down works in all forward and reverse gears but it was designed to lower first gear ground speed, so the tractor could run a tiller off the PTO shaft. Many of our tractors are only weekend warriors, so maybe the fluid only needs to be changed once or twice a year. Extending or neglecting to do fluid changes only guarantees that there will be problems. Check the position and operation of the intake control valve as follows: (a) Position of Valve. You've done it, I haven't. Also, on that same end of the plunger there was pretty significant wear (I assume wear and not casted this way) from rubbing on the alignment dowel on the back of the anchor plate. Remove the right inspection plate that has the hydraulic dip-stick. Other than that I just dress the gravel drive a few times. Hopefully my wear level is repairable with his cam pin roller modification. The most important plug is the one at the pump. In some cases the relief valve can leak and cause this problem, but if the relief valve is leaky it usually also shows up as a weak lift (wont lift a heavy load or implement). If those two things check out ok turn off the engine and remove the right side access cover (the one with the dipstick) and slide your hand down along the control rod into the oil and feel the end of the rod where it goes into the control valve pivot. It consists of a pto driven piston type pump with internal control valves and a lift cylinder connected to the rear lift arms. It just ain't possible to adjust the lift linkage on the 8N Ford unless you have a jig to use so that the end of the control rod ends up in the right position. Wrong? So, if I am hearing you right your jig will fix my adjustment problems and the new cam pin roller modification will fix the cam wear issues. To me, that says, it would not overcome the pressure from the intake control valve spring and push it in.

Make sure the rod is connected and that it is moving the control valve spools in and out as you move the lift control lever up and down. It is impossible to adjust the 8N lift with the instructions in most manuals. Bending the control arm is a lazy man's "fix" for a worn cam follower pin. Before doing anything to the lift it should first be inspected for any internal leakage. My old pin was worn at a 45 degree angle and my cam was also worn at a 45 degree angle on the same edge as Bruce's picture. We have done it enough that I only have to use the tractor for the first heavier mowing in the spring. Come to think of it that might have been a little too profound a remark!
