Hi everybody and thanks for all these usefull answers! I am going to have the parts to assemble all the modifications tomorrow. I did find the factory relief valve of the 3pt😀 I have another question, does anybody have the factory settings of the 3pt regulation valve?(the one on the picture and...

For the moment I will keep focused on replumbing the loader with what I can find here. Hopefully within the week I should make it. If it gets to getting off the round flange I will send you a picture of the inside. But I try to avoid dismantling working mechanisms as I can be short of spare...

After thinking about it I am actually not sure about that, is the out connection on the picture connected to a power place or this just flows back to the transmission case? There is obviously an error somewhere as I can control the 3pt with the loader controls...

It is not connected as a power beyond system, the return hose goes directly back to the transmission case.

Here is the way the fluid flows in the loader power controls.

I would be really glad if I had such a connection plate, unfortunately it is not the case... (picture). I think the best option for me is to add an intermediary plate between the power line and the tractor connection, either at the pump exit or at the end of the line near the 3pt input (but if I...

Ok, I keep all the options open, it will mostly depend on what parts I will be able to find here.

Thanks for pushing me into the idea that I am on the wright way! I am pretty sure my loader controls (valve) does not have the possibility to be used in a "power beyond" system, from here my idea to have it in series instead of in parallel, as it would most likely not work. I can't make a...

Thank you very much for all your precise and useful answers! I will now assemble all the needed parts, it might take a while as I am quite restricted in my choices here🙁 Thanks again for all!

Since I first opened this thread I did not change anything as I did not get the time. I plan to do so now. Can you tell me if the main hydraulic power line (on picture) is thick enough to be mig welded? Or should it be tig?

If this is an easier solution I will of course keep it in mind, my question than would be: does the way the loader controls are connected to the hydraulics of the tractor have an importance? Mine are connected this way (picture joined), and I think it is a weard way to connect them as if I do...

At the moment I see no point in changing my loader control system, adding a valve in the system between the pump and the loader should be enough. Plus the effect will then be on all the hydraulics, including 3pt.

Thanks! Will try this (I explained my motivation in my upper message).

Thanks for your answer. My point is to add a valve anyway to the system. When I push either the loader or the 3pt lift to the maximum extension/load the pump starts to make a weard hi tone noise, which for me sounds like over pressure. I changed the pump but the noise is the same (the sound...

Hi all, I have finally decided to add a relief valve in the system. I then have the following question, what is the nominative working pressure for this pump? (I plan to put the valve at the power exit of the pump). On the net I haven't found a precise answer (from 80 bar to 200...). As I will...

Ok, thanks for your help! :)

Thanks for your answer! As it might be quite impossible for me to get anything for a Kubota here I have a question: is the round cover you mention (the one connecting the oil income to the tractor) thick enough to be drilled and have a thread made directly in it? It would allow me to have a...

Thanks for your prompt answer! I think I will try to connect the loader as you say. The point that worries me is what you say about the relief valve, I can't see any in the loader system. And there is no chance I might find one here...:( the closest Kubota dealer is in Russia, 4000km... If I...

Hello, My name is Yann, I am french but I live in Kyrghizstan (central Asia) where I have a horse ride business. To help me in caring of my horses I bought a "gray market" L1801 (Zen Noh). As I plan to be able to work with it quite a long time I imediately made all oil changes, Axes, Gear...
