Hooking up third function, rear remotes, and a backhoe line.

[poseidon18]

Good afternoon everyone, thought I'd share this image of hose routing for hooking up a third function, rear remotes, and backhoe circuit. Forgive the art quality, i never claimed to be one lol.

I would not recommend that plumbing.

Oh? Why not?

Oh? Why not?

The backhoe goes last because it has no power beyond and you are overpressuring the tank port.

Loader->3rd function->Rear remotes->BH->Block

Your rear remotes probably need a power beyond port for the same reason.

I don't understand how I'd be overpressuring. Could you draw me a diagram of how you'd do it?

Everything is working right now, tested all functions.

You are feeding the 3rd fumctiom with the tank port on the backhoe. Every time you use the 3rd function the tank port sees that pressure. That can be as high as 2000 PSI and a costly failure.

Before I draw it up what do you have for remotes - OEM or aftermarket.

It works until it breaks.

Aftermarket, summit. I thought the orange was the supply from the loader circuit.

Here is the outlet block on your tractor.

Here is the proper plumbing with ports and flow paths labeled.

OP— have a look at this thread:

3rd Function hydraulic routing?

Hi, New member that recently bought a used L3901 with LA575 FEL and BH77 backhoe. I don’t have any experience with tractors but I am an electronics engineer so I have some technical background. The previous owner had installed a Land Pride 3rd Function kit. I picked up a used SGC1060 grapple...

So the P is (B), T is (D), and PB is (C)?

Thank you, I appreciate the help. I can be a bit hard headed.

Nothing hardheaded in this thread. You asked reasonable questions and listened to my answers. I hope the answers wete reasonable and helped.

They are and they will. Unfortunately, I already had mounted, zip tied, and put abrasion sleeves on the lot of it..... ‍. I'll redo it tomorrow

In Dan’s diagram of the hydraulic system for the outlet block the answer is YES

I followed your routing, thank you very much for that. I had to relocate the hard bracket for the backhoe because I'm using iso flat connectors and they were interfering with the three point. Now on to creating the bridge between the hoe and kubota subframe.

Depending on your size, you may end up feeling a little pinched sitting on the mounted backhoe seat while doing work, with the lower part of the ROPS attachment you’re showing.
Here’s how the factory kit instructions said to mount it.

Is that a kubota kit? Mine is from summit. I see your point about maybe being cramped but I'll just have to cross that bridge when I get ther as this backhoe mated to this machine will be a one off.
