Adding 4th rear remote to 5085M

[AKfish]

John Deere used to call this a MultiCoupler. I think made by Faster. I wish my 640 loader had one instead of six separate couplers, but too pricey to retro fit.

The third function hoses are marked green and yellow. They are in the middle of the multicoupler. I would swap hoses to get them to the outside of the multicoupler. Then below the the multicoupler (between valve and tractor half of multicoupler) I would install a pair of quick couplers (in the third function hoses). When you want to use the third function at the rear, disconnect and connect hoses from the rear to the hoses from the third function valve.

You can get colored tie wraps from Grainger.

I think that Zebra meant "fourth function"... as in: Then below the the multicoupler (between valve and tractor half of multicoupler) I would install a pair of quick couplers (in the third function hoses). When you want to use the FOURTH function at the rear, disconnect and connect hoses from the rear to the hoses for the third function valve.

That would work. And you would use the rocker switch on the joystick to use the fourth rear hydraulic cylinder.

Of course, you would not have the option of "switching" between the front 3rd SCV function to the rear 4th SCV function with an EH funtionality. That would have to be a "manual" function - connecting and disconnecting the QD's.

Another approach might be to install the Power Beyond Circuit at the rear of the tractor and plumb in an electric diverter (EH circuit) that could be controlled via a rocker switch on the right hand console. You would have QD's at the PBC and could connect the hyd top link into the Power Beyond Circuit.

If you use the power beyond circuit you will need an electric double acting valve, not diverter valve....

Just wanted to clarify.

It will have to allow continous flow back to the sump - open center - as well as diverting flow for double acting cylinder use.

Yep...

I took a look at the power beyond kit, and it looks like it connects directly to the block feeding the rear SCVs as seen in this pic:

And the parts that make up the kit:

Perhaps if I ordered just the bracket itself and then the following items from Surplus Center?

Note how this model has the work ports blocked in neutral, which I believe is what I want to make the top link hold its position, right?

And a 1 station series subplate (item 9-5883-1):

Would those be the pieces I'd need?

It would be way cool if I could find someone to machine me a subplate that would bolt right up against the oem 3 SCV block and the solenoid valve.

looks like a great choice and idea pclausen!

The GPM might not be high enough... but looks good in theory. Good research. Curious about the tractor PBC. How does the backhoe, etc. connect? No QD's?

Part numbers 3 and 9 look like quick couplers

I meant use the mid valve's 3rd function at the rear, but I see what you mean, at the rear it would be considered a 4th function.

Could a diverter be installed in the mid valve's 3rd function lines to the multicouper than routed to the rear for a forth function? Lot more costly than swapping between quick couplers, but more convient.

 

[pclausen]

Yes, parts 3 and 9 are the quick couplers, but I think all I would want would be the bracket and then mount 2 female couplers in it as I don't want a PB loop, just something to give me a 4th rear SCV. Leveraging the mid 3rd SCV for this does seem like a great idea.

So these appears to be the options (from least to most expensive):

1. Install a pair of hoses that plug into the 3rd mid SCV outs on the front, and are permanently mounted on the back to the PB bracket.

2. Install EH diverter valve on 3rd mid SCV and switch in cab, otherwise same as option 1.

3. Install EH double acting valve and plumb into rear SCV block somehow, making sure to not compromise flow (18.4 GPM?), and utilize PB bracket. This might be tricky if tapping fluid from rear SCV block.

2 might be just as expensive as 3 I suspect, but maybe not.
