external hyd. valve

Ok I have a external hyd. valve that goes between your legs mounted on a MF 50.

I used it a long time ago with a one way cylinder and now want to use it with a two way cylinder.

What port do I need to tie into to make it a 2 way valve. Look at the picture and let me know.

THANKS

MF 50 Diesel with Multipower(rebuilt) has 4200 actual hours on it. not a bad old girl.

love the 3cyl. perkins.

That valve is not capable of running a two-way cylinder.

You are going to need a different valve at that location....... or use the valve you have to power a second valve that is capable of running a two-way cylinder.
 
let me rephrase what I am wanting to do......I just need the spool to raise the haybine.......but I want to be able to plug in the other hose on the hyd. cylinder so I don't have to take the hose off the cylinder..........


I am justing needing a one way cylinder but hook up 2 hoses so if I change tractors......I can still use the haybine without having to add the hose back on the cylinder.

is there somewhere I can plug into the tractor, so I can still plug in the extra hose on the cylinder?? I don't want to have to change cylinder if I change tractors on the haybine..........

thanks
 
Eric is right, that's the early valve, one way use only. You need the later valve for double action use. Will have ball handles instead of the TEE style you have now.
 
I don't think there is a port like you are seeking. It would need to be below the oil level in the tranny to keep the extra hose full of oil.

Is there a possibility that the other tractor you are using will run a one-way cylinder? If so you could use a one-way on the swather and save a lot of "rigging".
 
We have a John Deere hay conditioner with a single acting cylinder that raises the mower. Our tractors have 2 spool valves which both can work double acting cylinders, but we only hook the one hose for the single acting cylinder to one of the ports on the one spool valve. Don't know why you would need to rig up a extra hose for use behind a different tractor.
 
Hello Scotty -

There's a return port on the upper left side of the cover, somewhere in the vicinity if the breather but on the side. A 3/8 or 1/2" pipe plug with an Allen socket head. You can plumb your return line into that.

I wouldn't be concerned with keeping the unloaded side of the cylinder and hose filled with oil - single acting cylinders work that way, and seen to last ok.

A trick I've used for quick disconnect fittings in setups like this is to polarize the connections so the hoses cannot be connected in reverse. The lead from the pressure port on the valve has the female quick disconnect body fitted, and the return line, from the transmission cover port, has the male end on it. The hoses have to be long enough to connect up without interference, but short enough to keep them out of the way at the back of the tractor.

The connections won't fit into the normal mounting bracket, but the two ends can be connected together when not in use, as well as the hoses on the implement. The added benefit - the ends are kept clean without those pesky covers that always get torn off and lost.

Don't confuse that return port plug with the plugs on both sides of the cover near the front - they're pressure.
 
what about the port that is on the right side? someone has put an elbow in it.......is it a pressure port? see picture

thanks
 
That's a pressure port. There should be a plug on the left, opposite to that - another pressure port. Apparently they could be used for a single acting cyl, using the normal 3-point position control lever with the lift arms strapped down. The Ferguson system is designed so that as the arms come up, pump delivery is reduced until at the top there's no oil being pumped into the system.

There's something in the back of my mind that says you may have to lock those arms down with the single acting valve you have.

Perhaps someone else can confirm that, or tell me I'm having a minor brain-fart!

You can remove that elbow and use it on the higher port further back on the left side. Plug the hole with the plug you remove.
