rear remotes

[Piston]

I was looking at my loader valve today and am a little puzzeled as to where I will make my connection;as the Pb is already being used for my back hoe.

So your saying that the PB hose coming out of your FEL valve is going to the PB to the back of your tractor that you hook your backhoe into right?

Basically what your going to do, is simply "insert" your new valve between the two. Your going to replace the hose your talking about with one that goes from the same PB port from your FEL, to the IN port of your new valve.

So then, you have a problem because now there is no hose going to your PB that your backhoe goes to.....
Not to worry, because you will just get another hose, to go from the PB port of your fancy new shiny valve, to the original PB port you plug your backhoe into. SOOOOOO, all you did was insert a valve between the FEL and PB.

There's one more hose to deal with and your installation is done. IT's the OUT port of the valve, back to your return line. That's it for the valve itself. You'll still need to add your 2 hoses per spool (total of 4 more hoses) which will go to your new Quick disconnects.

Clear as mud?

You'll need a PB adapter as well to add to the PB port of the new valve. That way fluid will still flow to the backhoe hose. I expect that the fluid out from the backhoe goes to the 3-point connection, since that's the last stop on the hydraulic circuit.

Good point Sean :thumbsup:
I was assuming you ordered the new valve with the PB sleeve already in it.
Do you have a link to the exact valve you ordered?

 

[drobtoy]

OK, I understand a little bit more now about this power beyond thing.

I don't know how to send a link to the valve I bought. That wil require a computer lesson.

The valve I bought is from surplus center 2 spool 8 GPM Prince item #9-7862


MB21BB5C1 DA valve convertble to power beyond or closed center.

Let me know if I need to order the sleeve.

Good point Sean on the return hose from the back hoe. I'll see if I can follow it back to find out where it goes.

Thanks guys D

 

[Piston]

Yup, that valve is perfect. Surplus Center - 2 SPOOL 8 GPM PRINCE MB21BB5C1 DA VALVE

Just make sure you have it setup for PB. The instructions should clearly show this when you get it.

If the specs don't say that it has the sleeve included, you'll have to order it separately. I'm pretty sure you'll need it, although I don't know exactly how your backhoe is plumbed in.

I do know I had to use one for mine. The PB port on my loader valve used to go to the inlet on the 3 point valve . I disconnected that hose, fed it into my new remote valve, then the PB sleeve went in the connection from the remote valve outlet to the 3 point.

You do have the right valve, in that it's usable with a PB system. Europeans often refer to power beyond as high pressure carry-over, which is a little more self-explanatory.

OK Sean,

I'll have to give some more though after the valve comes in. The disciption said convertible to pb or open center. I'll read the directions when it gets here.
My plumbing seems to go like this right now.

I have a power beyond hose coming off of the front end loader valve and goes straight back to the backhoe. When the backhoe is connected it has a what I think must be a high pressure return that goes back to a small "block" ???? under the step on thre right side of the tractor. From there it must be feeding the 3 point? When the back hoe is not on the tractor I simply connect the hose that was running the backhoe right back into itself by way of QD's

That sounds about right. If the hoe weren't involved the PB line from the loader valve would go directly to the junction block under the right step, then it's hard-piped up to the 3-point valve.

You can install your remote valve anywhere between the pump and the 3-point, as long as the 3-point valve is the last one in the series circuit. Typically on Kubota they're after the loader valve. All the valves prior to the 3-point valve need a power beyond sleeve, either built in or added to them.

Mine goes like this: loader>>remote>>3 point. The first valves take priority over the later ones. In other words while the loader is being moved, if you're using all the available flow to operate the loader then there is no flow to either the 3-point or the remote until the loader valve is no longer being operated.

Your hoe valve is also PB compatible, the outlet feeds the junction block then the 3-point in turn. If you start the tractor with the hoe hoses not connected, it should go over the relief valve because the fluid path is obstructed. Not a good situation, it builds a lot of heat in the fluid fairly quickly.

...but I am just leaning when it comes to hydraulics....

You've come to the right place, welcome to TBN; even thou I'm late to this thread :ashamed:

...Don't be discouraged by the "use the search function police"...

:thumbsup::thumbsup::thumbsup: (beside the search feature is pretty poor, imo)

...My setup looks like a spaghetti mess!

Mine, too! ...but who cares what it looks like - I just love how it works. I would have recommended 3 spools... only if you can afford it.

...I don't know how to send a link to the valve...

Just copy and paste the URL address into the post and it will be converted for you. When it comes to posting photos of your build, if you don't know how, just ask us. Good Luck with your build.

PS. when mounting the spools, make sure that it doesn't interfere with the hoe mounted.

 

[drobtoy]

Still waiting for my spool to come in. They are a little solw to ship, it just got shipped yesterday.

Thanks for the computer lesson Teg.

I will try to take photos and document my build. Its the least I can do for all the members who are sharing info and photos of your builds.

Thinking about what I will need for hoses and fitting. Reading materials list from your builds very helpful.

I noticed that Teg said he may have been alble to use 1/4" hose and fittings instead of 3/8".

I see others have used 1/2".

Is there a prefferance among members????

 

[Chilly807]

I used 3/8, because that was the size everything else was on the tractor.

Sean

 

[Piston]

I don't remember exactly what size I used, but it was the same as everything else. I did use 1/4" though for the hydraulic scarifiers on my box blade only because it slows down the flow a little bit. I also have 1/4" on my top and tilt cylinders for the same reason. I would use the same diameter hoses as the rest of your tractor to be safe, definitely no smaller.

Boy did that pissed me off... UPS would deliver within 3 days but they would not package it for four @#$%^^&* days (there's a rant on TBN about that already...)

Thanks for the computer lesson Teg.

no problem

I noticed that Teg said he may have been alble to use 1/4" hose and fittings instead of 3/8".

It depends on how fast you need it to move and the PSI rating... I think that most applications need smaller precise movements vs. quicker movements. Make sure the hose can handle the psi pressure. Your dump cart might work better with 3/8"... The grapple doesn't need lots of pressure (or speed) but the hydraulic Top and tilt may be subjected to extra pressure.

 

[Chilly807]

A woodsplitter, for example, needs all the flow it can get. I'd prefer to install an orifice or restriction at the implement if you need slower movement. Keep in mind any restriction that won't allow full pump flow will cause fluid to go over the relief valve. The supply line to the remote valve also carries flow to your 3-point valve further down stream, and returns unneeded fluid to the sump.

Sean

 

[drobtoy]

I got my new 2 spool valve today and new questions has come to light. The directions say that if I"m going to use the power beyond option that I install the supplied high pressure carry over plug into the internal threads inside the " C " port which I did. Than it says to connect hydraulic line from "C" port to a down stream function and the " T " port to the tank. ( Simple enough ) Done.
My question is ( how will this port supply oil down stream when its plugged ? ) or is it plugged ?

Hopefully someone can shed some light on this for me.

In the mean time I will read some more and prep and paint the valve. D

 

[Chilly807]

As I recall, the "plug" is more of a sleeve. The hose adapter fitting or hose end screws into the outside of it.

You can see mine as the right hand connection in the attached pic. The hose leaving it goes to my 3-point hitch.

Hi all ,

I have the prince wolverine MB valve. Apparerantly there is a couple of configerations for this valve.

option 1) hydraulic circuit , standard open center.

option 2) circuit using optional power beyond option. Which is what I thought I needed.

Option 2 asked me to install a threaded high pressure plug in the " C " port.

Is an one familer with this valve?

Do I not use the power beyond option?

Thanks

 

[Chilly807]

You definitely need the power beyond sleeve, which valve you have doesn't change that.

Sean

 

[teg]

You *HAVE* to have Power Beyond (since this feeds/powers the 3 point hitch). Do what ever the instructions says to do to make that happen. I don't know how or why it works with the plug/sleeve... I'm just happy that it does.

 

[drobtoy]

OK. I think I can do this. Im off and running I have the valve painted and I have a location picked out for mounting it. I will finish mounting tomorrow and start shopping for fittings. Thanks everyone for your help. D
