1533/1635 Power Beyond

[aledobud]

I have a third function valve I want to use for a grapple and need to buy hose to reroute the power beyond. Does anyone know for sure what type and size fittings are on the hose ends for the hose coming out of the power beyond port on the loader valve? I also want to get a confirmation that I have identified the power beyond port.
I believe it is the one with the "T" stamp and it has the hose attached, not the pipe.

I have a picture of what I think is the power beyond port and a copy of the parts catalog with the hose in question.

Thanks

My recollection is it’s a metric fitting or an o ring style. That’s why they have the little adapter hose. But I’m not 100% what it is. It should be easy enough to pull off and either measure or take to your local shop and have a hose made.

Thanks, I'll do that if I can't find out for sure. I didn't want to take the hose off and leave it off for long. I'm not experienced working on hydraulics. Being that the loader valve is maybe the low point in the plumbing, is oil going to flow/drip continuously until it drains everything above it? I could plug it, but still need to know what fitting to use.

Shove a golf tee in it.

P is for power beyond T is for tank or the return , backwards is bad

P is for power beyond T is for tank or the return , backwards is bad

Worth repeating this... P = High pressure and T = Low pressure return to the tank.

This is a little confusing. On this valve, the port stamped P is going into the valve from the pump. If you look at the description in the parts manual, the line coming out of the T port says pressure and the one next to it(which doesn't have a stamp I can find) says return. Also, in the video above, it was the T port he was calling the power beyond. I don't want to do this wrong, though, so I will contact the dealer and make sure.

I know the video setup works.....

I finally got the third function kit installed and hooked up to the grapple. Other than a couple of leaks I had to fix, all seems to be working fine. The one thing I was a little surprised about, was how much the hydraulic hoses flex or "jump" when you activate the third function. I guess it makes sense. It's a sudden redirect of flow. The two lines to the grapple flex, as does the hose coming out of the valve to the downstream power beyond pipe. I can't see the power beyond hose going into the valve, but I assume it is flexing too. Will all of that flexing shorten the life of the hoses? I am most concerned about the power beyond hoses. Either of those would be a pretty bad failure, since they are always under pressure.

All voodoo

Hydraulics is definitely voodoo for me. First time I have done any type of hydraulics work. The number of different fittings for the same application is amazing. I have three different types of quick disconnects on the tractor now. The four sets that came on the tractor for the loader, one set that came with the grapple(there was one set they used to connect the two hoses together), and one set that I got from Tractor Supply. And I have another set that came with the third function valve(why one set, I do not understand). I may swap that one with the one from Tractor Supply. The Tractor Supply one (Pioneer brand) has a constant drip.

I finally got to use the grapple this weekend. Works great. I think this will be my most used implement, other than the shredder.

 

[please help desperate]

I highly doubt I'll get a response to this but I got a summit universal kit and hooked it up just as others have said with the "pressure return port" off the loader valve and can't get anything to work off it. Can someone who has done this on a 1533 shuttle please give me some insight as to how you plumbed it. I haven't been able to get with summit thier customer service hours suck I work on the road and by the time I get to my tractor on Friday they're already closed for the day.

I haven't done this to ours yet, but planning on it in the next few days (hopefully). You have to use the Power Beyond Port on the control valve. The "pressure return port" would be labeled T to tank. I have messed with open center hydraulics on my old backhoe, I do know that using the return line port won't work. There is a video on Youtube of a 1533 with HST where he shows the port. I'm going to try to link it:

Good luck, and if I remember to, I'll post my results.
