I have a 5310 4WD- no cab, bought new with 541 loader, original joystick control as well as 4 rear connections controlled by two mid mount levers in front of seat , normally used for hydraulic scrape blade. I want to add the W R Long 3rd function kit to the loader stick so I can add a grapple. W R long was unable to help with the appropriate JD power beyond kit for my application. I have seen several on JD parts diagrams but am unclear as to which, if any would
work with this configuration.
Any help is much appreciated.

I'm confused. If you are looking to add a 3rd function to the loader why do you care about a Power Beyond kit?

I think he wants to ID the PB lines so he can add in a electro-hydraulic valve to make a new 3rd function.

This is the control for rear remotes
If you can identify the IN and OUT of that valve block, you can add the new solenoid valve in series with it.

You most likely have a IN (or P for pressure) port, a OUT (or T for tank) port, and a PB (or BYD for beyond) port. Tracing the three lines may help reveal which is which, my WAG is the two in the picture I can see (one hardline and one hose) are the OUT and PB, but I'm certainly not sure.

Hard Line on top goes to pump at engine. I'll trace others

Hose on back of block goes to top of lift. There are no P, T, BP or marks of any kind visible on the mid block or rear block. there are two plugs on each however. Could they be used for the two lines needed for third function. I assume the first two lines on the mid block are pressure and the third may or may not be as well.

I doubt you can use the 'plugs', they may not even be real ports. You will have to interrupt the line from the block to the loader valve, I think anyway.

Correction- hose on side of mid block goes to rock shaft. Hose at rear of mid block goes to loader block at rear. I've got to think that the mid block is where the in and out ones need to be attached - plug on side and rear as well as on top- three plugs on that end of block where pressure relief valve is - DEF marking cast on that side. I was hoping someone would be familiar with this mid block valve body. I seem to be no closer to an answer, but thank you for your help. Hope springs eternal!

I had a 5310 up until a year and a half ago. I had this upgrade done to my tractor when I bought my grapple by my dealer. I can tell you it was a convoluted setup that involved at least 2 solenoid valves and a lot of other plumbing. Prior to that I had a WR Long diverter for my 4 way bucket.
My 5310 was setup different than yours. What are the 2 control handles on the block valve for? I didn't have that valve between my legs.

I have a question rather than an answer: same tractor, more basic issue regarding activating the rear hydraulics, if you don't mind. I just acquired an older 5310 via a property purchase and need to learn how to use it. Previous owner moved out of state. As mentioned, I'm trying to activate the rear hydraulics and don't see a switch to divert hydraulic power to the rear from the front (and use the joystick for controlling the implement(s) in the back vs the front loader). In my tractor, there is a hydraulic manifold mounted high in the cab behind the driver's right shoulder. It has two levers, one for each rear SCV I think, but after connecting one of the loose rear hydraulic hoses (tractor side) to the disc mower, I still couldn't get rear hydraulic power. I don't have the levers under the seat that you appear to have. I'm first looking for some kind of switch that activates hydraulic power to the rear (vs the front) and then looking for some advice on which of the four or five loose hydraulic hoses hanging down from the back of the tractor to connect to the mower. The mower only has one hydraulic attachment, which appears odd that there's not two.

Thanks very much for any advice.

Re: "This is the control for the rear remotes." => I also am trying to figure out my rear remote configuration and activation mechanism...how to activate the rear remotes. I have a valve block (or hydraulic manifold) like you, on my 5310, with the two levers and four to six hoses entering/exiting. I am unable just using these levers to get power to the rear (PTO) implements. I can't find a switch that shifts hydraulic power from the front loader to the rear. There seems to be no switch...if there was a switch it would make figuring this out easier. Therefore, in the absence of divert switch (front to back), it seems like you should be able to use the levers on the valve block to do this. I did get some reaction in the hose back to the implement but no power, then just a loud screech, so I was doing something wrong. Power was still directed to the front loader. So I need to figure out how to switch or divert hydraulic power to the rear....any help appreciated. Just got this tractor in a property purchase and need to mow a field bad.
