UFO Problems

[vwbeetle]

I could only find one knob under the seat. By turning it I was able to change the rate at which the lift arms would drop. With the valve all the way off, the UFO cylinder still leaked down. I have fabricated a replacement and secured the hydraulic cylinder off to the side until I can remove it and get it repaired or replaced. Mickey, I am curious what would prevent this cylinder from being rebuilt?

When I disconnect the cylinder, what should I do to the hydraulic lines? Do I cap them off?

Looks like I was all wet in saying these cyl were not rebuildable. Went outside and looked again and while all the top end of the cyl is welded together on closer inspection I noted on the lower end it looks like the end is screwed into the cyl and needs a spaner to lock into end cap and unscrew.

Now feeling better about my own unit if it ever started to leak.

Hello All,

I have a FX-17D tractor with UFO control. Can someone explain how to set and use the automatic controls?

thanks

Sorry it has been awhile since I visited this thread. I completely removed the UFO unit and disconnected the electrical connections for the joy-stick controller. I was hoping to cure a problem I'm having with my 3ph but it didn't help. My 3ph, when carrying a load like rotary cutter, will not stay up. It will gradually fall down about three inches and then "jump" back up. When the engine is off the 3ph will gradually fall all the way down. The 3ph will stay up when I shut off the valve under the seat (mine only has one valve which controls the rate of fall when the 3ph control lever is pushed down to lower the hitch) even when the engine is shut off. I was hoping that the problem was caused by a leaking seal in the UFO cylinder, allowing fluid to circulate around the 3ph lift cylinder somehow. This, however, was not the culprit. Does this mean the problem is in the 3ph lift cylinder seals/o-rings, or in the shut-off valve , or maybe in the controller valve. I don't know much about tractors but these are the only things left that I can think of. Are there any other possibilities. Thanks

It is in the 3pt cylinder or the valve, but probably the cylinder.

Thanks, Mike. If it is the cylinder, shouldn't I be able to remove the valve plate ( or whatever it is called) under the seat, pull the cylinder out and replace the 0-rings or seals? Should I also go ahead and rebuild the valve while I' in there?

That is as I understand it. But I have never done it. Maybe someone who has will chime in. I do not believe that there is much that you can do with the valve. Maybe a few orings and such but for the most part there is not much "rebuildable." The cylinder should cure it for you.
