![]() I really would like to find out if anyone else has had this problem and knows what I should look for. I have the FO 4, but not helping me much in the trouble shooting area. Hopefully, next week while I'm on Christmas vacation, I can get the top cover pulled, and I'm probably gonna buy Zane Sherman's adjustment gig to check and make sure everything is adjusted correctly. I also have the position / draft control lever in the "up" position for position control. I know there are some adjustments to the springs under the cover to adjust the lift operation, but I'm wondering if something isn't worn out, or broken. When I lower the lever, they will move a bit slower to a point, then go to the bottom of travel. When I raise the lift quadrant, the arms don't move until the lever is nearly at the top, then of course, they raise all the way up, no in between. I did a lot of work on the first one, so I'm familiar with how they work, but I've never encountered this problem. The images are missing, but still you may find this of some useas it does give the lengths of the springs. In the down postion, the touch control lever sets the 'draft' you want for the implement you are using. Thus with draft control the implement is either full up - transport position - or full down - in working position. Have a question about my 8N hydraulics.įirst of all, this the 3rd 8N I've owned since '96. It gives the procedure from the operators manual, then how to check and straighten the control arm, then the quadrant adjustment from the operators manual. Where as draft control sets the amount of drag - or depth of a plow. If the problem persists, overhaul the pump.Hello all. Crank, but do not start the engine, until oil comes out the opening and replace the plug. The 8N hydraulic system consists of the following components: an internal piston pump a lift cover which contains the lift cylinder (ram) several valves: control valves, pressure relief valve, check valve, back pressure valve, and safety valve and a selector lever that mechanically determines draft mode or transportation mode. If it's been replaced by the piston pump, remove the hex plug from the top front. If you still have the original vane pump I'm not sure which plug is the bleeder. Your problem is likely a pump that's lost its prime. Transmission oil weight has no effect on the hydraulics of either a Golden Jubilee or an NAA. The little lever on the right is draft/position control. Either you have a '54 NAA or a '53 Golden Jubilee. If I use straight hydraulic fluid I have the same problem you have. If I use straight 80-90 it works fine in the summer but won't work in the winter. With my 8N, I use a mixture of 80-90 and universal tractor hydraulic fluid. 9N9818A Governor to Carburetor Control Rod Fits Ford New Holland 2N 8N 9N. New Aftermarket Throttle Control Plate Fits Ford 8N Tractors Replaces 8N9889A. You probably just need a little heavier fluid in the trans. Throttle Control Lever fits Ford 8N 8N9805. I dont remember on the right side lever if up is draft or depth. And i believe the lever on the left is the PTO engagement lever. The lever on the right is your draft/ depth control lever.

I would also like to have it so it could run a one way cylinder, is there a simple way to plumb an outlet in and what does that little lever do that is right under the seat to the right and also the lever by your foot on the left side? Thanks ![]() Just got it out again and now the 3pt wont lift at all with nothing on it. It seemed to work better when it was cold than when it was warm a few weeks later when i used it on the rear blade to move some gravel around. Used it last year to plow about 2 acres just for fun and at the end it was having trouble lifting the 3pt up all the way. Have a nice'54 Jubilee Ford that dad bought a few years ago because his dad had one when he was a kid and it was a local tractor so I painted it up.
