HV5902 installation guide on my Ford 4100

[Timpy]

Hello guys,

I have a 4600 tractor and already struggling quite a while on connecting the front end loader valves to the tractor... After reading this thread I think probably somebody could help me out? I made a similar plate as the HV5902 my own but would like to know which holes are used directly in the tractor rear axle housing. Probably all holes run through and are just brought to the side so something else could be added? Or does some holes need to blocked. I have a selector plate, so I put this plate in between.
Thanks in advance!

You lost me part way back. You made your own sandwich plate but you don't know which holes are which? If that's the case how could you know which ports in the block to connect to connect with internal passages? I think your game plan was missing a few pages at the outset here. Maybe you can post a few photos of your creation.

Thanks Harry in Ky for the fast reply.
I will try to explain the situation;

The tractor had a front end loader mounted on it when I bought it. It was mounted on the selector valve underneath the driver seat. So the pressure line ran to the external valve and returned to the sump of the rear axle housing. See the 3 pictures I've attached to this text.

This was the begin situation, but you could only use the front end loader OR the 3point hitch. AND the lever of the 3 point hitch must be up.
A while ago I had a dangerous situation where the lever was still up and I switched the selector valve (pulled it out). So the lift went up and the lift that was on the back hit my cabin and broke my working lights at the back.
So I start looking around and found this topic.
I started making also a plate that could be mounted in between the selector valve and the tractor hydraulics as a sandwich without changing anything to the system.
I drilled all holes following the pattern of the selector valve and made connections to the side in a similar way as the plate I saw here and of pictures over the internet. I even made a 3D drawing with a cut trough so it was easier to route the connections (it's attached to this text).
As I made it myself and after trying all kind combinations I am doubting 2 things:
- do I made the connections on a different way internally
- is the external valve good for this application (din oil ML2)

As I wrote above, the valve is a DIN OIL valve ML2 type. A more specific typenumber I don't find on it. In the meanwhile I found a datasheet of it and saw that power beyond (carry over) functionalities are possible. But I don't know the internals of this valve of course...
The only thing I see, is that the port where the carry over must be done, has a thread more deeper in the valve (G1/4)than the one on the surface (G3/8). After going trough the manual I saw there is a 'carry over kit' which contains only a G1/4 plug. So in my point of view I need to plug the thread below and connect the upper thread as the 'beyond power' connection. I don't know this is common?
Attached some pictures of the valve

Well it looks like it should work. At least the concept is correct. Your loader valve looks good as well, and yes some do use a plug threaded into an internal port to convert to power beyond. That seems simple enough.

It doesn't work like this, that's the reason why I'm writing this text... Do somebody know the internal connections of the block?
