Direction of flow from diverter valve

[jcummins]

Everything is plumber correctly...remember the grapple WORKS. I just want the shut or clamping action of the grapple to happen when I pull the joystick inward, which is the same as the curl up.

Everyone is saying to switch the hoses...that is the EXACT FIRST THING I did after my work Saturday, and on every curl up, I had to stop the curl, center the joystick, hit the button and push the joystick to the right to tighten the grapple...and I knew I was going to switch the hoses. The problem is, it simply makes the grapple inoperable when I do that.

BukitCase...my joystick works the way you describe, pull inward your curl up (which is what I want) and the valve is plumbed the way you describe.

I'm was going out take some pics, retest, thinking of taking the hoses loose at the grapple, and check the hydraulic flow into a bucket....but that seems pointless...we KNOW it works, I just want the valve to work opposite of the side it is activated on the joystick.

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. :thumbsup:

How to get out of regen?...just move it a little, not a lot? If so I've moved a little...I moved it a lot too.

I just retested in the non functional hook up. I can feel and hear the hydraulic activate in the lines all the way to the grapple cylinder, both left right with the joystick, but the cylinder does not move.

Here is close up pics of the cylinder on this grapple.

If you have a hyd gage in a tee at the IN port of the FEL valve, and the grapple switch was on, would you expect to see any pressure when the cyl fully extended?

If the cyl moves, you would say that is normal.

So in reversing the hoses, the cyl should work opposite than before, and you would expect pressure at max cyl extension.

So do you see pressure with both hoses normal and hoses switched?

Fluid should flow to a port when the lever is moved.

The grapple switch should be selected before you move the FEL lever or problems will occur.

I think that this is the solution, actually it has to be.

As far as any of the switches failing without the diodes, none that I know of. I should supply them, but how many people are actually going to use them?

Something else JC, you are not suppose to actuate the valve while under pressure like you want to do, :no: or how I understand that you want to do anyway. Maybe I have just mis understood you. But I thought that you said that you wanted to push your control button on off on off while your lever was in the curl position so that you were curling and closing the grapple all at the same time. THIS type of use is not recommended. Not saying that it is actually going to do any damage, I don't know, but that valve is not intended to work in that fashion.

You can't curl and grapple at the same time, it is either curl or grapple.

You can try, but the pressure will cause trouble.

Which part of your valve is the regen, the first part of lever throw or to the far right.

The last testing I did, the switch was activated before any joystick movement.

Brain...yes I was thinking of working that way. I few times Saturday I release the button before centering the joystick and found the function changed, then quickly repressed it and it went back to the grapple. I was hoping as you just curl up with the grapple loaded, joystick to the left to just touch the button to tighten the grapple, and continue the curl.

J_J...I see pressure by the hoses moving in the non functional hookup. I can feel the pressure in the line at the cylinder...the cylinder just doesn't move.

A little movement of the joystick, the curl is slow. Hard all the way to the left, the curl is hard and fast.
Last retest I tried, slow, I tried hard. The hard just made the lines jump more.

I don't expect the curl and grapple at the same time. I realize when the button is pressed, the curl stops.

I don't expect the curl and grapple at the same time. I realize when the button is pressed, the curl stops.

Not thinking at the same exact time, but with pressure on the solenoid from being in the curl mode, my guess is that it isn't going to last as long as it should. Might be wrong though. :confused3:

I think that you have some hoses routed wrong. You are not suppose to have regen for curl up, it is for a fast dump cycle. Might want to check that out.
