Loader Valve plumbed with BYO, although no remotes

That's odd. I have never seen us NOT put the relief pressure in the manual. It's not on the spec page like it usually is....

Please be more specific, exactly what are you talking about.

Just curious why the remote valve relief is better set to the loader relief rather than the tractor main relief?

The tractor main relief is normally the 3pt relief valve as most all other valves are add on.

You can set the loader relief higher than the other valves if the pump can handle that pressure and then set the remote the same as the loader relief. The 3pt relief should be set to the tractor specs.

The lowest relief setting upstream will limit the rest of the system.

Ok, I was thinking it was like I had drawn in my diagram and the relief was actually a separate valve and not part of the 3 pt valve. I understand now, thanks.

I think I am on the right track, I found this document that shows a proper installation for a backhoe. The remote valve will replace "backhoe" in the picture.

What does everyone think about installing remote qd's like this next picture and then qd my connections to the remote valve? I figured this way I could detach the valve and hook to a PB type external work unit. Is this an ok idea? I decided not to connect to a return near the back of the tractor because it looks like that would bypass the filter and any contamination could end up in the tank.

I am starting my remotes project and sure would appreciate help

I am diving into this project now that I saved enough to get the first phase completed. If you all could help me through this I sure would appreciate it. I haven't ever worked with hydraulics!

I purchased the valves and am laying them out. Here is my plan so far. I don't have much room so I am using two, two spool valves and I am placing one on each side of my seat. They are both 8gpm Prince Wolverine valves. For the t and t I am going to have the side link with float. The other three are standard spring to center valves.
The cardboard is a template for a mounting plate that I am planning on making out of 1/4" steel.

I am detaching the PB and return port from the loader valve and routing those lines towards the new remotes. I plan to plumb my pressure in on the first new valve from the PB port on the loader valve then from the PB from valve one to the pressure in on valve two. Then I will come from PB out from valve two and I am going to join up with the detached line that was originally from the PB out on the Loader valve so it feeds my hydraulic block and goes to the three point. Does this sound right?

For the return to tank lines I am joining them from both valves together and running the lines toward the disconnected line from the loader valve return. I will add a new line from the loader valve return and I will t them all together to get the fluid back to the hydraulic block. Is this ok too?

Are there any heat concerns from sending the fluid through three valves? My pump is rated at 7.8 gpm.

Now I need to think about the load check comments from JJ. I am going to look for those settings in my loader manual.

Do not mess with the load checks.

There are load check in each valve to prevent back flow and prevent the load shifting when you move the lever.

Sorry, meant to say check on the relief pressures. I think you said to set them to the loader relief pressure. The remote valves are preset to 2500 psi.

I found that there is a published port relief setting on the loader lift circuit of 4000 psi. I am not sure if this is significant for my install?

I am cutting out the mounting plate.

Well it took two blades, now I am locating the valves so I can mount those and measure for hoses.

Here they are mounted up.

It's a beautiful day in Michigan! Today I drilled for my quick disconnects. I really like the step drill bits. I was able to drill all eight in a couple of hours.
