Gc2610 BH valve

[liberty2701]

I just dug a trench with my bh and something did not seem right. In order to make a flat bottom trench you need to pull on the right lever and then pull the left lever to get the two actions for a flat bottom. It seems that the right lever overrides the left lever when i pull them, even if the left is pulled first. Should both levers be able to operate together? If I feather on and off the right lever it seems to give me the control I think I am supposed to have. It has been 5 months since I used the BH so I do not recall. Not sure if this is a problem. Thanks

I see alot of views but no replies. I think my post is a little confusing. My question in more simple terms is that should the right lever override the left lever during back hoe operation? I thought they should operate together.

You should be able to pull both levers, an flat bottom out. I have no trouble with my wallenstein hoe.

No, one lever should not always override the other. What you describe sounds odd.

But, there can be operational limits, due to the amount of fluid available. And, perhaps it is just your unfamiliarity with the unit.

FLuid flow should not be a problem because If I am operating with no load and I pull the left lever first and then the right, the left lever function stops and the right lever function continues to go. I am running Amsoil fluid by the way. I guess I have a problem?

 

[ray66v]

Based on my understanding of what your saying, it does not appear to be working as it should. Perhaps something is not connected properly?

Amsoil ATH fluid should not be a factor, about half of us are using it.

All connections are the same as they always been. They are also color coded. I know you said it does not appear to be right. Could you double check your machine before I drive 1 1/2 hrs to the dealer. I would greatly appreciate it. Let me clarify exactly what it does. If i am raising the boom with the left lever and then pull the right lever to retract the bucket the boom will stop raising, hence the right lever overides the left. Does not matter the rpm.

If the valves are in parallel the one with the lowest or least load will move first so what your describing would be possible.

That is normal. I checked it for you, and mine did exactly the same thing.

You will also notice similar limits in the FEL.

When you get used to operating the unit, you will be able to use it smoothly without even noticing this.

Thanks alot for all your help. That is why I love this site.

Just to confirm,mine also operates this way!!!!

The flow will be shared by all the spools engaged. The more spools in use, the slower each function will be.

I believe the slow down is due to the load on the different cyl.

If you had a gage on each cyl you might see this in action.

Mine works the same.

In this case there is no sharing of the fluid between the two, the bucket curling function completely overrides the dipper stick. Movement by the dipper completely stops with any engagement of the bucket cylinder.

My wag is, it was done because there is a limited amount of fluid available, and they wanted to assure full power to the later input.

I can however, easily dig smoothly with this hoe, bumping in and out of this power sharing arrangement, without really thinking about it.

The FEL also has a similar limitation, as you can either dump the bucket, or raise and lower it. But you can't actually do both simultaneously.

I find this operation more troublesome than the backhoe operation. It is much more difficult for me to go back and forth, between dumping and raising the bucket at the same time, and do it smoothly.

Pressure is what produced the power.

GPM dictates the speed of operation.

You should be able to do two operation at the same time.

If you push one lever to max, and the relief comes on, and then you push another lever, does the relief quit relieving, if so, that means that some flow is now going to the other spool, and if you push two spools to max, then the relief will activate. l

On your FEL joystick, can you not push the lever at an angle, other that up/dwn, or left/right..

I could not use the B/H right now, because it's raining. But I did check the FEL.

Yes, you can move the control stick diagonally. When you do that, lets say between raising and dumping the bucket, You find a point where a slight movement either way, toggles between the two functions, but you cannot simultaneously do both functions. One function stops completely, while the other operates.

I always found it difficult to raise, and dump the bucket in any kind of fluid motion.

This is also what the OP noticed in the B/H operation.

mine is the same.

As usual, Ray beat me to it. Yep, these GCs have a tendency to only allow one lever control movement at a time on the BH, at least that's what I've found on my 2310.

That's because you have a life!

:laughing::laughing: Well, maybe, Ray. Not this summer, however... spent LOTS of hours at the airport trying to bring my PA-22-150 "up to snuff." It had lots of little issues that I discovered as I went over it with a fine-tooth comb after I bought it. Folks didn't see me much at home, for sure. On the bright side, it passed its annual! :cool2:

Oh- third pic is not mine... a replica at Owl's Head Transportation Museum in Maine that we watched take off and fly around. (Did manage to get away a couple of times this summer.)
