How to remove Power Beyond Fitting

[Kubota3710]

I'm installing a 3rd function on a LS 4046. I have to remove the power beyond value, and then attach this to the grapple valve kit. Here is a picture of the fitting to be removed. It looks like it has a nut on both the top and the bottom of the off coming hydraulic hose. How do I remove the nuts and the hose? Just turn the bottom nut? Or hold the inside nut, and turn the outside nut. Don't want to mess it up. Thanks RIch

I dont think that fitting is for PB, might be a return. cant see enough of the valve to make a good guess

That is a banjo fitting. hold the inner hex and unscrew the outer hex. It is a hollow bolt with a copper washer on each side of "banjo" on the end of the line. You can then unscrew the inner hex and remove from the valve. It is probably a straight pipe thread of some kind.

For mudstopper. It is line 4 in this picture. The G822S03 to the left is the loader value. The G827S01 is the Remote Control Value. So I am pretty certain that it is the Power Beyond Port. Definitely don't want to be wrong......

Looks like line 3 is the return. As has already been said, the fitting is a banjo type. use a wrench to hold the fitting next to the valve and turn the nut on the outside and it should unscrew a hollow bolt with a couple of copper washers.

Re: How to remove Power Beyond Fitting on LS 4046

Ok, well glad I asked and I am all stop until I am sure I have the correct line. Here is a better pic of the entire loader control value. Line 4 is coming out the bottom and going back to the remote control valve (I think that drives the 2 rear remotes on the tractor). Line 3 is on the backside of the loader valve and goes back to the hydraulic filter area. So advice welcomed.

 

[muddstopper]

You have it right. Line 3 going to the filter is your return. Line 4 going to the other control valve is the PB

thanks for confirmation. WIll tackle it in the morning.

Does the kit you are installing have the proper fittings to tie into what is there? Banjos aren't that common. Just don't want you to take it apart thinking your local hydraulic shop can make up a hose that will work.

3710, Looking at the diagram which is not very definitive I assume item G823SO1 is the pump, G822SO3 is the valve you are attaching to, but what is G8827SO1? If That item is another valve assembly fed power from SO3 then the line between the two is the PB and your new valve has to go in that line. So, we need to know the function of each major component first. The picture does not show what other connections are hidden. I would assume the four ports across from the valve operators go to the FEL cylinders. I can see only one other connected line so there are two others hidden which are the Tank (T) and the PB, Just pulling off lines may not tell you which is PB if you cannot tract out the lines on the tractor.

Most of the time, a SAE/ORB fitting or adapter can be used in place of the banjo.

The kit has different fittings that replace the banjo fitting on both ends of the removed hydraulic line. The new 3rd function valve goes inbetween the power beyond value and where it returns to rear remotes. It is the L.R. Long kit.

Perfect! My concerns are nullified and I learned something!

I assume you mean W.R. Long... is it the Electric over Hydraulic Valve Kit on this web page? W.R. Long Valve Kits

 

[Kubota3710]

Yes, my mistake. It is W.R. Long.

Thanks for the help all. INstalled and working nicely. Just need to better constrain the hydraulic lines at the front of the loader. Planning on some kind of bracket to attach to loader.

Oh boy.

1) the PB fitting supplies P (Pump or think of it as hydraulic power or hydraulic pressure).

2) You need to tap into the P line in series (meaning inline) with your valve.

3) The photo you provided shows a simple banjo fitting.

4) Do you know where the other end of that line goes? (likely the three point and then to T tank).

5) If 4, then figure out where your valve will be mounted, yank off the entire line, and bring the line and your valve into your local hydraulic jobber and have two custom-made lines fabbed up.

6) Install those lines with your valve onto the P from the valve you showed the photo and T going to wherever the other end of the line went.

7) You now need to plumb lines A snd B off of your new hydro valve.

I promise this is easy once you get the hang of it.

It looks like he got it done ok.

OP I like that grapple.
