Harry has the PowerBeyond kit on his tractor, not the 3rd SCV kit, You will not have a problem using the 3rd SCV and the 3PH at the same time.

Harry,
Sounds like you are in a real jam with the dealer situation. I will try to help, but I am no expert either, I know enough to be dangerous!

First, It sounds like the PB kit is complete the way you have it, like already said, it's main purpose is to provide a hookup for a backhoe, and you do not want the 3PH working with the BH on.

Second, Its sounds to me like you need the 3rd SCV kit to operate your toplink and your tiller. The handle for the 3rd SCV will go right in your fender alongside the 3PH lever. I cannot offer part numbers for this kit, but I think I've read that it is about $250.00 or so and fairly easy to install yourself. You could also hook your splitter to the 3rd SCV couplers, and bungee the handle down so your have a constant flow so you can operate it like you do now, and your 3PH will still work.
I think this will be the cheapest solution to your problem.

There are ALOT of 4310 owners on TBN, I hope somebody will chime in with the part #'s and prices for you. If not, you can register with JDParts and try to look it up yourself. Or go the main JD site, then to the configurator to BUILD YOUR OWN, and add the 3rd SCV kit to get the whole goods parts number...

Also, try searching TBN for "4310 Remotes", I am sure you get alot of hits. Just be sure to change the date range to "ALL POSTA" as it only defaults to one week.

Thanks, just knowing it's called a 3rd SCV valve is a help. I've searched the parts online and without knowing what you are looking for and not recognizing it when you see it leaves me with more guesses than I started with.

Still, does anyone know if dumping the return into the 3PH instead of the top return would cause a problem? With the log splitter, I can only imagine the 3PH would not run or run slow if you happened to be splitting at the same time you were using the lift... but that's not likely. Otherwise, I just want to lift, move, drop without moving hoses around.

When the 3PH is disconnected, it sees no flow at all. Not sure how the rockshaft works... would it consider the variable pressure/flow to be a change in position (plow digging in) and start trying to correct it or something?

Since deciding to keep the older tractor the backhoe and tiller will continue using the pto pump for now. The centerlink I have has a valve on it, you turn around to adjust, instead of screwing you fiddle with the lever... err did I say that /forums/images/graemlins/blush.gif

So, if I can dump into the 3PH safely, that'll be the cost of a couple of fittings.

The Third valve for the 4310 has two different possible parts:

The first is:
Serial Number H330095, -P335041, -S330068 = LVB25084


The Second is:
Serial Number H330096, -P335042, -S330069 = LVB25569

Harry, Now that you have seen the images I deleted them so the thread is readable.

hmmm... I remember seeing that before, the saleman told me the Power Beyond Kit was what I needed as it provided a higher flow rate and steady power. I was never told it disabled the 3PH in order to use it. From their later reaction, they didn't know it either.

I was told the kit you show here only added a second lever to control strictly a two way flow, in or out and was only suitable as a lever for a center link (mine already had one mounted right on it) or to control a few other things. I was even told I would need both kits if I had a tiller going and a hydraulic center link. hmmm... now how would that work, tiller runs and I can change the angle but I sure can't pick it up.

Anyway, at the time I was having to trust the dealer to know their business. I guess I'm going to have to revisit this little issue.

I think I'll call JD and refuse to accept any referals until I get someone that can explain how this system does work.

Thanks.

oh, and if any engineers or other's out there know if it'll hurt to dump through the 3PH, I'd still like to know. I've already invested in the kit I have... if I can atleast make it mostly function I'd be ok with that.

Another option is the DSCV diverter kit but that is about a thousand dollars+ .

CAn you explain to use non log splitter users why you need a hydrolic top link with it? Also how many valves does it take to run the log splitter?

Robert, I'm not an engineer but will try to help, since you keep going back to the idea of dumping the return line from the splitter back to the TPH. I don't think that will work because the return from the log splitter would not have the pressure required to operate the three point hitch, like you said, it just "drains" back to the tractor. I also have a 4310 with a 48 back hoe and the power beyond, have thought about other uses for the PB but don't have any needs at this time. I wouldn't think swapping the hydraulic line to move the splitter would be that much of a hassle,[should be easy to get to, though you do have to shut down the engine and unload the hydraulic pressure] you should try changing those lines after you raise the back hoe and pin it to the frame, there is about 2 inchs between the couplers and part of the seat frame to work in. Can't help with the tiller or center link problems. Good luck, John

A red flag should have gone up right when the salesman said this. He obviously did not know what he was talking about, especially the higher flow rate. Sheeesh. /forums/images/graemlins/frown.gif /forums/images/graemlins/frown.gif

to answer some questions...

The centerlink (toplink or 3rd link) is not for the log splitter, it is for the scrape box, scrape blade, root rake, disc etc... I can change the angle the full range in a few seconds by turning around and moving the lever on the the side of it instead of turning the link and screwing it in or out while twisted over a high back seat for several minutes.

The log splitter simply takes in fluid on an open center valve. When not in use the fluid is just running through it at full pressure, in and out. When the valve is moved the fluid is forced to travel into the cylinder and the return stops flowing, when in reverse flow the fluid is forced into the front chamber and the cylinder is withdrawn. When in neutral it's just a full bypass right back to the tractor.

If my thinking is correct, when in neutral, the 3PH will not be able to tell the difference between going through a 2 foot loop vs. a 10+ foot loop (2 5' hoses plus a valve housing). When I'm moving the splitter, the 3PH will stop seeing flow just as if unplugged.

The more I hear from you guys and analyze this, I don't think it'll be a problem for the splitter or a centerlink with an open center. Lever in the center = passive loop, which is the same as the passive loop. The lift simply won't move when using the remote device, which is OK. I just need to make sure all my hoses will take the same pressure as the kit loop hose.

For a tiller or some other active flow device where the fluid is driving a turbine the return fluid would never be a constant useful pressure and would not properly drive the 3PH. The pressure could even surge on the return, which I'd think could be bad. So I won't do that.

I think I'll get some parts and make a simple adapter and try it out. I'll let guys know what happens. May take a couple of weeks though, Christmas and all.

Also, the centerlink seems to have at least made a few of you curious. It is nothing more than a small cylinder with a valve attached to it with couple of adapters to plug in. The lever is right on top. We cut the ends of a regular screw type link and welded them on each end. The cylinder was chosen by size so short = about the length of the screw type link full in and long was the same as it's full extended length.

The log splitter was a must. First, I'd much rather maintain 1 engine that does many things than many engines some of which sit idle for months. Second, we have very large trees around, many oaks at 36+ inches. I've not cut down a tree in 10 years, the ones that fall or limbs that break during storms have supplied all the wood I've needed. I have about 30 cords on the ground now since that last tornado came through. I use the tractor to pull the fallen trees out and put them on something to keep them off the ground. The problem was, most of the log splitters I tried would stall or simple not have the power to do the job. I also wanted a splitter that would go horizontal and vertical. This one has done the job well. With the load match turned on, the tractor will never stall and this past weekend I split a 40" log section with a limb section in it. Oh, she groaned but it split it.

Oh, and really nice tree sections go to the local mill.

How about a tee to select between the 3PH and the splitter, you would have to have some type of shut off valves to choose where the flow would be dedicated to. Though if you say the flow would be at full pressure through the splitter when it's not in use then I guess your idea would work, but what about when you are using the splitter, not sure if that would be an O.K. route to return the fluid to the pump.[through the 3PH]. With the tee you would not be compromising anything, you would just have to turn a valve handle to direct the flow to where you wanted it. Just my thinking out loud,sounds like you know more about hydraulics than I do. I recently (3 years ago) got a 8H.P. tow behind splitter, vertical or horizontal, only use it about 2-3 days a year so yes it is a pain when you have to remove the mice and nests along with other tweaking just to get it running every year. It has all the power I need but don't know why or how anyone would want use it horizontally. John
