Direction of flow from diverter valve

[jcummins]

The more post on the thread the more confused I get...and it centers around regen...AND the fact everyone said switch the hoses to make it do what I want it to do, but it doesn't work and regen which I can't even recognize is part of it.

First...how do I get into regen? How do I know I'm in regen? All I know, is I move the joystick left, it curls up...if I move far left it moves faster. Same with moving right. You can go slow....you can go fast.

I push the button move joystick to the left the grapple opens, move far left it opens faster. Same with moving right except it closes...slow or fast.

I think the problem is the regen function.
With the hoses swapped to make it work like you want it to, it is trying to add the extend side to the rod side.
That won't work because the volume of the extend side is larger than the rod side.
Move your joystick out of regen and it will work.

I move the joystick slow...is that out of regen?...it doesn't work.

This poor boy is completely confused.

It just occurred to me.....

I want the grapple to clamp with joystick pulled left....that is an extension of the grapple cylinder.

Joystick pulled left curls up....that is a contraction of the curl cylinders.

Is that the limitation?

I want that way, so I can clamp/curl up almost at the same time with the button being the control. I found in use as I curl up, you want to clamp a little more.

Above is my post #12, which no one commented on. Is the flow greater on the hydraulic path to extend the cylinder since the base of the cylinder behind the rod is bigger? And is the opposite for the other path because it is smaller area in the cylinder?

IF true, then I cannot extend the grapple cylinder on the curl up cycle which is designed into the fel to retract the loader cylinders?

Does this make any sense?

Try this.

Move you fel lever all the way to the right. Now push harder. It should click into a detent. You are now out of regen and your grapple should work the way you want. This is the way the fel valve on my b2320 works.

Bradwynn...not that way on this tractor. Anyway if you go out of regen on the far right...how would you use the joystick to control the grapple, since you have to move it back and forth left/right to work it with the diverter valve.

The more I study regen, the more I think I go into the 'fast dump' especially to bang the bucket against the stops on the FEL to get dirt unstuck. But a point you are in regen, or out of it, is not clear to me at all.

Ok, I'm going to throw you a sinking curve ball. Connect your loader lift hoses to the left side of the diverter. Best to reconnect the curl lines to the lift circuit. Use the forward backward motion to check out all of your after market system.

I have little doubt that the problem is in the plumbing and the loader regen portion of the valve. It is often suggested that this type of valve not even be used where there is a regen circuit. I'm thinking this is why, although neither myself or any other of my customers have had a problem, you just stay out of the regen mode and everything works just fine. Has in the past anyway.

That's low and outside, more like a knuckle ball.

I'm beginning to understand the problem. The grapple works, it's just the left/right function is not intuitive to me. I kept losing the grip in the grapple on large bunches of brush, due to that trait. I had to slow wayyyy down to get it right. For some, it may not be an issue. It probably will improve over time with me, but right now, using rear remotes with the grapple on my previous tractor was more intuitive, since my hand just fell to the rear remote handle, the fel centered auto, then I went back to the fel handle. Getting the timing down on the button, relative to the joystick position...isn't as intuitive as I thought it would be. IF...I could switch the left./right function it would be MUCH MUCH better, but I'm seeing it's not going to work. "It is often suggested that this type of valve not even be used where there is a regen circuit." and I'm understanding why. Kind of wish I'd went with power beyond now.

Do you know how to stay out of regen mode on this tractor? I for sure do not.

I just thought of something, I keep saying the left and right side of the diverter for in and out, you have the diverter upside down, so when I say left, it should be to the right side and vise versa. Are the in lines going to the right side of the diverter, the outside edge of the tractor? The valve has to have the flow in the proper direction or it will not work properly.

 

[jcummins]

Input from the tractor is P1 & P2, which is on the right side in the picture....the outside lines. I've got it plumb right....remember IT WORKS....and the curl/dump works.

I put upside down to protect that end and avoid getting dirt down into the connections.

I don't understand why you need to clamp more when curling up?

I have two different style grapples and once it is clamped, it won't go any farther down.

Above is my post #12, which no one commented on. Is the flow greater on the hydraulic path to extend the cylinder since the base of the cylinder behind the rod is bigger? Yes, slightly. And is the opposite for the other path because it is smaller area in the cylinder? Yes, slightly, but only because of the different volumes that the oil is filling, not because of any mechanical restriction in the system.

IF true, then I cannot extend the grapple cylinder on the curl up cycle which is designed into the fel to retract the loader (bucket)cylinders? No, the reason is the regen function in the loader valve.

Think of it this way, go back in time before you added the diverter valve. Swap the hoses to the bucket cylinders, try to curl, depending on where it is it may move one way then lock up.
