Mx5100 remotes. Questions.

Forget that blocked off hole. I bet it was going to be the return and was just to hard and slow for them to bend up 3 tubes, so much faster to do it the way it's done. You got it right go for it.

Here's just an idea... What about buying the backhoe hookups? May get you all the necessary plumbing?

Not sure how a backhoe attaches. Or what parts they use and where it ties in. I will look into it though, bit have a feeling it ain't gonna be cheap either

I don't think Ive ever tried to purposely operate the remote and 3pth at the same time. I'd need two right hands.

I do regularly flip the 3pth position control lever from one extreme to the other and then immediately move the hydraulic top link (my rear remotes most common use). Since it takes a few second for the 3pth to completely raise, I think I'd notice if there operation was mutually exclusive. :confused3:

Yes, the rear remotes are OC.

Another thing to consider: Kubota OEM will not allow the first valve in the stack to be a float/detent type (the second and/or third can be). I don't know why but it may be germane to your plans.

I am pretty sure that is only on tractors that nest the levers up next to the 3-pt lever. It's a matter of space. The first valve lever goes behind the 3-pt lever and has less room for throw. The next two valves go to the side of the 3-pt lever and have a longer throw, letting you engage floats and detents.

Sorry I am late to see this and respond. On my L3200, the factory valve block takes the PB line that formerly ran from the loader to the 3-pt (an external line) and diverts it to be the PB supply to valves. Return from the valves goes through the hole(s) in the case under the plate that comes off. Then a new external PB line runs from the valve PB out back to the 3-pt.

Sounds like the MX setup is more sophisticated, and does away with the external PB lines. It would make sense that one of the holes is the PB input, which normally gets routed straight to the 3-pt if no valves are installed.

If you are to install valves, then the block you machine has to have these functions:

1) passes PB to valves
2) provides return to tank from valves (return through the current unused hole in the blank plate).
3) passes PB flow through to 3-pt when valves not actuated

I think you've already arrived at those conclusions, but I wanted to confirm it's inline with my experience putting the factory kit on my L, other than the external/internal PB lines.

Now that makes sense.

I've got float on 1 and 2, could have also put it on 3. When I installed the valves, float valves have a "can" that hangs down lower and my 1st valve bearly cleared the 3pt top cover. More space below the 2nd and 3rd valves so I can see if there isn't enough room under there why it's hard to fit a float on 1st valve but the bigger the tractor the more room there is.

Well....not good news/progress tonight.

I started taking some measurements and doing some trig to figure out how to machine this thing. But I think I overlooked something.

With the small footprint of this conver plate, even getting -06 fittings to work would be challenging. Would require mounting with FHCS and countersinking them. As the hex on a -06 ORB fitting would interfere. And getting to a 1/2" fitting just won't work without having to make the block alot bigger, and cross drilling in the side to make the ports come out somewhere other than the face of the manifold. And it won't leave hardly any meat between the ports and bolt holes.

Makes sense now why Kubota used that tube contraption.

There is no doubt I could probably make something work, but at this point I thin it is gonna just be easier to pull PB elsewhere.

I like that answer

I like this answer too!
I was trying to come up with a hydraulic system design reason and came up empty.
