Since I broke the plunger, I might as well remove the hydraulic cover and check the piston and cylinder. 8N/IMG_3357.jpgĪnd you will notice the draft control spring plate is showing its age. Tried to unscrew the yoke from the draft control plunger. will take off the yoke and fill the divet in with weld. Started by removing the top link rocker to expose the yoke. Started ripping down the hydraulics to find the problem Tomorrow I take off the side plates to get a look at the boiler room, LOL. So I'm thinking tighten the draft control yoke and new draft control spring plate with pin? Never mind three fingers, I could spin it freely with one finger my baby finger. Prior to raising the implement to fully raised position, I moved the top link to the lowest hole on the top link rocker and, when the implement was up, I did the three finger check on the main control spring. So I'm thinking stuck valve in the pump or possible scored cylinder or blown cylinder rings? However, after a couple of tries moving the implement up and down, when I left the lever in the up position, the implement would rise to the top and then fall to the ground, only to rise to the top again and repeat the process until I lowered the control lever. Hooked up an implement to the 3 point hitch and raised it up. I will be taking the cover off to look at the hydraulics when it stops raining.įrom what I've read, it could be anything from a worn relief valve to a scored cylinder and/or piston, loose control spring, stuck control valve, pump check valve, stuck inlet and/or outlet valves or worn quadrant draft control pin.Ĭan someone please tell me what foul demon has possessed my poor three point hitch or am I going to have to do an exorcism in the form of a complete tear down of the pump and hydraulics?Īs always, your help is greatly appreciated.ĭid a little checking out of the hydraulics today. In the fie, it works intermittently, going to the top or just barely off the ground.Īfter discing the field, back to the house and I have spent the last two days researching the problem. So, off I go to disc a small field and, up goes the implement. Now we are back to the beginning again where I can just barely get it off the ground. Start the tractor again and now I have control of the implement.

It goes up and down like this four more times before I turn off the tractor. All while the lever is engaged in the up most position. And goes to the top and comes to the ground. The fourth time, I raise the discer and it goes to the top and then drops to the ground. Turn the machine off and down comes the discer. I engage the 3 point hitch and my pump comes to life growling low and up goes the discer. On a lark, I moved the top link to the upper hole. I always attach the top link to the bottom hole. On my tractor, the top link rocker has three holes in it. While blowing air, I raised and lowered the hitch with the discer on. Grabbed my air compressor, removed the dip stick for the 3 point hitch and stuck the nozzle in the hole and gave it some air. more like taking up the slack than getting it off the ground. Attach the discer and again, just barely of the ground. If I took the implement off, the arms of the three point hitch would raise to the top.įinally pulled the old girl up and changed all the oils. At best, it would just lift the implement enough to bounce and skip it along the ground while driving. I topped up the fluid but could not get the implement to raise up. I was discing a small field last year when the fluid for the three point hitch ran dry on the dip stick. Depress the clutch or turn off the machine with an implement raised, and it will come to ground within 15-20 seconds. The hydraulics on my tractor are a bit tired.

just find one big enought to drive into the gap under a tad bit of tension, and you will eliminate the free play, and then once again let that big spring handle compression and allow the rod to actuate the valving on the underside of the hyd topcover more correctly.Need your infinite wisdom regarding my Ford 1948 8n. That said, you can also shim it tight with a few large honkin flat washers with a notch cut out of them so they can straddle the rod. all the while tapping with a tack hammer. and allowing to cool, and then hitting with penetrating oil. some have reported luck by getting it red hot with a torch. 50 years of rust usually makes this more or less a 'unit' instead of individual parts, and you are likely to break it putting enough force on it to get it to screw in. ) but it mainly consists of screwing the youk ( that connects to the toplink rocker) into the rod. nd a tad different than the 1948 8n setup.

The fergy I&T manual at TSC will show how to adjust it.( this pump and hyd system is identical to the ford 1939-1947 9n/2n setup. draft control is not adjusted, and that free play is activating the valving to lift the plow.
