Power Beyond on 3x20 (new version??)

[B8FISH]

Anyone using the TSC or Northern Tool type splitter on a newer 3x20 series with Power Beyond? The PB set-up on my 3320 has 3 connections--the "normal" loop, and an extra connection on the left hand side (when viewed from the rear). It's not clear to me how to set-up the splitter in this arrangement. If you run the splitter from the loop output and then back into the loop input (the way you would on the older version of the PB) that's fine--but what's that other connector for?? Maybe a higher flow--direct return to the tank? If you use the output from the "loop" can you return thru the third connector (this would leave the "loop" apparently disconnected??)? I just want to find out the "right'" way to use this version of the rear hydraulics without doing any damage. Any suggestions?
Thanks,
B8fish

PS--and BTW, what is the size and style of those PB fittings--I don't see them readily at my local TSC?

I've attemptd to add a pic from the JD Parts site.

That other connector should be the direct return to the tank, dis-abling the 3PH. you would use that for a BH.
The logsplitter should be connected to the "normal loop"

 

[B8FISH]

KennyD--thanks. Do you use all 3 connections with a BH? Still wondering on the size and style of the actual PB fittings--so I can get the hoses etc. from TSC when I get the splitter.

No you dont use all three connectoins for BH.Just unplug the loop (hose)and cap the male end of hose and set a side.Now use right side outlet for pressure and left side for return.

Ahh--makes sense now. Thanks Jeff.

I just got thru adding PB to my 4300 a couple of weeks ago (the new style like yours)and it didnt make sense to me either until I hooked up the BH,then it clicked.

Kennyd,

The manual that came with the power beyond option on my 3320 calls for using the direct return connection whenever any implement is attached. As you point out this disables the 3PH operation as the rockshaft unit is by-passed.

You suggest the "normal loop" operation can be used with a log splitter (thus retaining 3PH operation). Is your suggestion based on the much smaller fluid flow required to operate the splitter vs. a BH? While retaining 3PH operation while using a splitter is desirable, I'm somewhat cautious about going against the operators manual.

 

[kennyd]

Woody,
I believe the manual assumes you will use the PB(PowerBeyond) for a BH(BackHoe). In that case, disabling the 3PH is a necessity.
For a LS(LogSpitter), having the 3PH operational is very desirable so you can adjust the height.

My suggestion is based on the fact that either loop has fluid flow available for use, the only difference is where it goes-either the tank or to the rockshaft.
The "flow" rate of a LS vs. a BH has nothing to due with my reasoning, neither uses any fluid from the flow when they are at neutral.

My 3130 has two lines for the back hoe. If I hook up a log splitter up to these I assume my 3ph will not operate. How do I hook up the log splitter and still use the 3ph? Is installing rear remotes the only way to accomplish this?

RPK,
Just so I understand correctly, your PB setup only has TWO connectors? It is different from the picture posted above?

 

[RPK]

Kennyd;

I have a female type quick disconnect and a small length of hose with a male type of connector at the back of the tractor. A hose from the backhoe connects to the female quick disconnect and the hose from the tractor connects to the backhoe. When the BH is off the tractor the hose has to be connected to the female connecto rat the rear of the tractor I assume so the fluid will circulate properly.

Kenny, thanks for the reply. So it appears that the new power beyond design with the rockshaft bypass option has nothing to do with fluid flow considerations but only with making sure that the 3PH is disabled when operating a BH. Not being familiar with a JD BH mounting configuration, I had not thought of this.

You should be able to plumb the LS into that loop, just have to get the right couplers and size of hose.

That is the way I see it

Good info--thanks all (especially KennyD). Still would like to know what size and style the actual fittings are on the PB. Are they 1/2" or 3/4", poppet style or some thing else? At TSC they actually have fittings that say--"old style JD", not sure if these are the correct ones or not. The list of fittings on-line (at surplus center etc.) is pretty long with a lot of different styles/types and just want to make sure to get the correct ones the first time. Also--does the 3rd SCV use the same style and size?

B8,
Which couplers will fit you remotes can sure be a mystery!
The couplers JD uses are made by Parker, and should have a part number on them that you can Google search. My 4110 uses 1/4" couplers, you probably have 3/8" on your machine. I went through all the searching, and trying to find online suppliers and all the headaches...finally I just ended up buying them at the JD parts counter at my dealer. They probably were a little more expensive, but at least I knew what I was getting, and could take them back if they did not fit. Having good parts guys when your trying to do a custom job can be invaluable! Also, learn to use JDparts.com to help figure out what you need.
Let me know if I can help more...

Kenny--thanks. I'm OK using JDParts--and after a little more investigation I have the sizes. Not sure why they only list the actual sizes for the female couplers and not the male plugs? Also--as an FYI the "new" style PB hookups are not all the same size--that third fitting off to the side appears to be 3/8" while the others appear to be 1/2".

Great, I'm glad you got it figured out, now you can help the next guy!

I guess the different size couplers are so when you plug in the BH, it can only go into the one that disables the 3PH?

On a semi-related note to this thread.... if one's only planned use for rear hydraulics is a log splitter, would it be best to just bungee open a rear SCV as opposed to adding a PB kit? And/or can you add the Deere PB kit w/o effectively disabling the 3PH?
