Power Beyond Installation

HobbleCreek · May 11, 2006

Has anyone here installed a Power Beyond Kit on a JD 4x20 or similar model? I am thinking about getting the kit but the installation price being quoted by the dealer is more than the price of the kit itself . . . ugh. If it's not terribly complicated and doesn't require a bunch of specialized tools I'm thinking of doing it myself, but not without getting input from you folks first.

Thanks,

Grant

I did my own on my 790. It wasn't bad and the directions were very good. Do some digging on the Deere site, they may have the instructions posted somewhere for you to get a better feel for it on your tractor. Maybe someone with your tractor can help more, or post some pics of the finished install /forums/images/graemlins/smile.gif

The cost at the dealer isn't out of line for all that is required, that is why by far the best way to get hydraulic options is done at time of original assembly.

(note: this pic is from the 4x10 series, should be very similar to the 3x20 and 4x20...)

The PB (orange) is plumbed into the DSCV block which is located behind the joystick. The lines run to the top back where a bracket mounts above the 3 point. And a return line (teal) runs to the side of the hydraulic fluid fill. The dark blue is the 3rd function.

A lot of stuff (wheel, fender, covers...) will likely have to be removed, to plumb this. Still it is probably a reasonable home shop project.

Why are you adding PB?

Somehow I had a feeling Mike would come through with the Deere info, thanks /forums/images/graemlins/smile.gif

Twas nothing! You have the real info! Can you tell more, did you have to take off a bunch or was it pretty easy..?

RobS · May 11, 2006

Upon further review I'm going to challenge what Mike has indicated. I believe both orange lines are for PB with DSCV installed. The teal line is the supply line for a tractor without the DSCV. As I recall, this was the one point I found confusing when I put my kit on. The kit comes with three lines and you only use two depending on whether or not you have the loader valve.

Still, great digging Mike /forums/images/graemlins/smile.gif

It wasn't hard, but there was a lot to it which explains the dealer cost. If I recall, I had to remove the RR wheel, fender, seat, panel below seat and probably some other stuff. That alone took an hour or so and as long to re-install. The PB kit itself was another hour or so. As I mentioned, the directions were very clear (other than only needing two of the three lines provided) and the fit is dead-nuts. I was very impressed with the routing and accuracy of the lines. Everything fit together like it was... well, like it was designed to /forums/images/graemlins/smile.gif

Rob, on the machines we are talking about, I am almost certain that the teal line is a larger line and the return to sump from the hoe. The supply is the orange line, with the hose connected; it loops back to power the rockshaft, when the hoe is in place the orange is its supply, the teal its return.

That;s what I thought about the install, not all that hard, but a lot of tear down and build back...

Maybe we're both on the right track Mike. The teal may be the common return and only one of the two orange lines shown is used. One definitely is shown on the DSCV so maybe the other one is the supply line for a non-DSCV tractor. Either way, it's confusing how they show the hose loop as it looks like it's connected to both orange lines and certainly not the teal line.

Mike, do you have PB on your tractor and if so, how many connection points are there. On mine there is but one set of connectors (one male/one female). Without the backhoe, the hose simply loops back to complete the circuit. With the hoe on, the hose is connected to the hoe and a return hose from the hoe completes the circuit. If I don't have a complete circuit, I deadhead the hydraulics. Haven't tried that and don't intend to.

BTW, should tractor guys be using the word "teal"?

When I connect my hoe, I disconnect the loop. The hose is left unconnected. The hoe's supply is connected to the top right fitting (orange) and the return is to the left connector (blue-green-yucky-color) once the hoe's lines are connected, you can no longer tilt the seat. I would like to fit an elbow on the return to fix that... when the hoe is not on there, the blue-green-yucky-color line is not in the circuit and unused. The bottom connector in the pic actually goes ito the side of the fill neck for the hydraulic fluid. It just dumps back into the sump.

Thanks for pointing out my foo-pah about teal, I am so embarrassed! /forums/images/graemlins/shocked.gif
