FRONT HYDRAULIC KUBOTA L3200

[Hamza]

Hello,

My name is Hamza and im owner of the Kubota L3200 2012 year.

I bought it few weeaks ago and i love it but i have a problem with it !!!

When i bought it it didnt come with front loader so i guess the problem come with that.
The problem is that i want hydraulic exits on back of my tractor but i dont know how to get it (i will attach pictures ) my relief valve looks like picture number one it doesnt have any exits on that valve so i cant attach any hydraulic hose on it but looking down the internet i finde pleanty of pictures and videos where other Kubota tractors have diffrent valve cover with 3 exits i asume that i need one of that...

My questions are:

1. Am i correct that i need that cover so i can get hydraulic exit on back of my tractor so i can hook a trailer that have hydraulic cilinder for unloading ?

2. If im correct where i can buy that one ?

3. If im wrog can you please help me how can get those exits.

I love this tractor it is perfect but this is very important for me so i would love for you to help me !!!


Best reguards

Yes, that is correct but you will also need a joystick (valve / spool) that is open center and has the power beyond plug installed.

Where are you, within the US?

Messick's for Kubota parts, can be shipped, or your local dealer...

{EDIT} THIS IS WHAT YOU HAVE NOT WHAT YOU WANT!!!! H23500 HYDRAULIC OUTLET BLOCK; don't forget the "O" rings, too. Then you'll need hoses to connect it up from the block to the joystick (spool/valve body) location. SEE Post #10 for the correct part....

Hello
Thank you for answering on my question.

Now i dont understand anything

Please if you have some spare time to help me.

1. Im from Bosnia and Hercegovina in Europe capital Sarajevo

2. Is there any chance to get pictures of that cover (inside part i cant finde anithing online ) so i can get it made for me here on cnc maschine..

3. On the upper 2 is it enterrence ? Does it need to bee a oval shape ( 2 connected holes) or 2 seperate holes ? The picture will be helpfoll a lot !

4. I bought velves and hoses from Zetor tractor i will attach pictures so you can see them are they ok for this or i need something different ?

Best regards
Hamza

Flip this valve over and take a few more photos... it looks good so far...

another member would have to say how the block is drilled (pathways the oil travels) Not sure if it's a straight shot or not,

My L2800 is what your L3200 turned into... they are similar...

Hi
Thank you you for your answer. I have a few more questions:
1. Regarding the outlet going to FEL, firstly that is a front-end loader, correct?
I'm connecting it as a main oil supplier on the valve?
2. The low pressure return part, is it coming from the valve back to the relief valve.
3. When it comes to the high pressure return, I'm still a bit confused. Can you clerify it further?

I'm attaching a few pictures of the valve and hoses, that you asked for. Hope this will be useful.

PS. One of the attached pictures is showing inside of my relief valve cover, I was wondering is it the same cilindre shape as yours on the upper exits or you have a separate exits?

Thanks,
Hamza

Hi
Thank you you for your answer. I have a few more questions:
1. Regarding the outlet going to FEL, firstly that is a front-end loader, correct?

It could either be for a Front end loader or just a valve with Power beyond (that could be used in the rear or the front). You can add a few of them, there is not a limited to how many you can add. I have 3 after the two for the Front End Loader...

I'm connecting it as a main oil supplier on the valve?
2. The low pressure return part, is it coming from the valve back to the relief valve.

So the high pressure is a continuous loop, and you tap into that with your hydraulics valve. It goes in series, one after another. When you are done "using" the high pressure for work, the low pressure oil return to the tank comes from the hydraulic cylinder... yes, from the valve.

3. When it comes to the high pressure return, I'm still a bit confused. Can you clerify it further?

High pressure return is just a continuation of "high pressure" to supply power to the 3 point hitch (or a backhoe or more valves). The high pressure is a continuous loop through FEL, any extra valves you might have which might be a backhoe and finally the 3 point hitch. It's always pumping (roughly) pumping 6 gallons per minute through the lines.

I'm attaching a few pictures of the valve and hoses, that you asked for. Hope this will be useful.

So the photo that I posted had 3 lines coming out of it, the reason I said this is hopeful is that, a valve with power beyond (which you need) has 4 hoses that operate the up/down and curl, then 3 more hoses; Power IN, Power Out (called Power Beyond) and a low pressure Return to tank...

One the last set of photos, you show the 4 lines but then only two other lines... I'll look again.

On the valve body, there should be letters cast into the valve, if you can get photos of that, hopefully, it will show what I need to see.

PS. One of the attached pictures is showing inside of my relief valve cover, I was wondering is it the same cilindre shape as yours on the upper exits or you have a separate exits?

Thanks,
Hamza

Never mind with the extra photo, what you have shows what I needed... pretty sure that will work. See photo attached.

So, your last photo, #8... I take it that is the cover you have now? which just connects the power out, to the high pressure return (which would be the "Power Beyond" from the valve...) Correct?

 

[old and tired]

My second post is wrong, I added text {in red} to show that part number is what you HAVE not what you want... Looking now for what you need to get, Guessing it just a straight port that you can screw in hydraulic hoses to....

Old and tired. That is the right one now. I was going say something before, glad I read all posts before I said anything.

Hi

Thank you very much for your help now i understand it the scheme was big help for me i will attach more pictures of valve here..
When i connect (air) on the IN port i get air on BYD all the time when i push the lever i get the (air) on the exits it depends on witch direction i push or witch lever on that exit i get (air) the BYD will bea constant flow of hydraulic ?
On the OUT i dont get any (air) but when i connect the air on OUT i get air on upper 4 exits ofc it depends on witch direction i pusch the leaver...

Hello Hamza,

Once you get the hydraulic adapter plate either bought or made on a machine shop, you can then use the picture shared by old and tired on post #5 as reference for your hydraulic connections.

Basically you'll have this, based on that picture:

Orange line (high pressure line) -> IN port on your valve

Grey Low pressure return -> OUT port on your valve

Green High pressure return -> BYD port on your valve. Now, you can remove that 90 degree fitting on this port if you need, but don't remove the bigger fitting where this 90 degree fitting connects to or the system won't work right. That's the Power Beyond (BYD) sleeve that provides flow for the rest of the system.

Looks like this:

Yes, hydraulic oil is constantly flowing in a circle through the whole system and dumping back into the main tank at high pressure. BYD (guessing) BeYonD port...

On the OUT i don't get any (air) but when i connect the air on OUT i get air on upper 4 exits of it depends on witch direction i push the leaver...

So the low pressure return, that valve's "Out"; is just to give a path for oil to drain back to the tank. When a hydraulic cylinder moves in one direction (gets pressurized), the oil in the opposite side of that cylinder (that doesn't get pressure), needs to drain (release pressure) that oil goes back into the tank under low pressure return to tank line.

When your dump trailer raises up, you are pressurizing that cylinder. When you let it down, that oil needs to be able to be able to release pressure and that oil needs to be able to flow back to the main tank. (hope this helps)

Hi

Thank you very much !!!
This was very helpful

Hi

Thank you very much !!!

No problem, what I don't know is how to set up your dump trailer since they (normally) use a single action cylinder (vs. everything that uses Double Action cylinder). Which, single action is power up and gravity pushes it down.

I don't know if you need a special valve body or if the one you have would work fine for that??? Does anyone know? I guess you could use a double acting (power moves in both directions) for your dump trailer....

I run a double acting cylinder on my homemade dump trailer but I'm actually using it as a single acting cylinder, by just using one of the ports and the other has a breather on it.

I run this setup with my remotes, which are double acting. Now, there is a little bit of room on my remotes where I can lower the dump trailer without forcing fluid through the relief valve but it's a little bit slow. I can move the lever all the way, which will lower faster,and force fluid through the relief. That is perfectly fine and I do it at idle so it's not pushing all the flow and max pressure and it's only a very short time anyway.

On my setup, I don't really need to force fluid through the relief valve because I have an hydraulic winch on the front of the tractor that's plumbed before the remotes and I always leave it in free spool. So when I lower the dump trailer, I'm also running the winch in free spool at the same time, so it's doesn't put any strain on the system.

Hii
Me again

I do evrything like you sad i will putt pictures in this post but i have 2 more questions im consernd about it and i dont want to demage somthing :

1. I have one action cilinder on my trailer and it is only one pipe line going to it will it bring oil back thru the same line when i lover it ? Or i need do put some second pipe line ?

2. I have a backhoe there is a two pipe lines on it one gets the hydraulic to it and second gets the fluid back to tractor ?
Im woried about second line that geting back fluid where do i connect it on high pressure return or on the low presure return ? And i will put the T shape spliter or how do you call it on high/low presure return to get that exit for backhoe ?

First off, great job on the install!!! And nice clean shop area... Secondly, Sorry but I do not know the answers... I know very little about backhoes and even less about plumbing a single action cylinder with a Kubota.

I would suggest that you post another question asking "How to mount/use a single action cylinder with L3200 and a backhoe?" Link that thread back to this thread...

I'm afraid this thread might not draw enough attention from the right people. And the fact that this is a whole other question vs. just asking about Front hydraulics (which normally would imply, simple hydraulics for a grapple).

In the new thread, tell them about the dump trailer. Were you going to have the backhoe on at the same time as the dump trailer??? Or are you asking about plumbing with the backhoe lines??? (I'm confused, now)

The other reason to start a new thread about using a single action hydraulic cylinder is that I don't recall ever seeing one!!

Other than ptsg mention above... ptsg, so did you only run one line to your single acting cylinder and cap off (not use) the other line (dead heading it?). That still doesn't answer the backhoe question...

When the backhoe is not on, I THINK there is a bypass hose that is connected in place of the backhoe... (not sure if that helps).

In my case, since I'm using a double acting cylinder as single acting, I only run one hose from the remotes to the cylinder. The non used port of the cylinder has a breather. It can't be plugged.

In Hamza's case with the backhoe, he can simply plug the backhoe to the new remotes (nice and clean install btw) and hold the lever with a bungee cord or fabricate some kind of holder for the lever.

The only thing to keep in mind, is to make sure in whatever direction the lever is pushed, the fluid must enter the backhoe valve using through the P port of the backhoe valve, because there is the risk of feeding the backhoe using the Tank port which is a bad thing.
