Ford 3910 A.S.C.Valve Problems

frankmako · Sep 29, 2007

I know someone has an answer on this problem. I must be missing something small!!

The auxiliary service control valve does not work on my Ford 3910. The three-point hitch works, but I cannot pull the A.S.C. valve out to the other two positions. Also, I cannot change the speed of the three-point hitch. The valve knob is set to the 吐ast setting (a good thing). The switch will not move back and forth (front and back) and it will not pull out.

I also have a double spool remote control valves on the tractor. My Ford Operator's Manual tells me to pull the A.S.C. valve handle fully out to operate external services only. Push fully in to operate the three-point linkage only (the position that it is in). And the mid-way position is selected to operate the three-point linkage and external cylinders simultaneously. But it will not move.

It has a flat head screw on the front side of the system, could this be a stop/safety screw??? I guest that I should back the screw out some and see if I can move the valve.

Are these the parts in question?

No, not the part in question. It is on the brake side, under the seat, just up from the floor board. I will take some pictures this week and post them. I know someone in the community has a Ford 3910.

True, but 3910's I have seen do not have an ASC valve. Photos will be great.

For some unknown reason I was using the incorrect name. The proper name is the flow control valve knob. It will not move. The operator's manual does not have much on it. But it is in the fast setting, so I guest that a good thing.

As for john bud, the pictures are A.C.S. valves, but not the one that I have. After I look at the pictures and my operator's manual I found out I was using the wrong name. In other words I was calling the flow control valve knob the A.S.C. valve.

But it still will not move back and forth (SLOW TO FAST).

Thanks to all that has looks at this problem.
