This is the valve I have for my drive motor. Not saying you need this but this is what I have.

https://www.surpluscenter.com/Hydra...Motor-Valve-w-Flow-Control-9-7497-30.axd

On my machine I have a 2 spool pump, one flow goes to the motor valve one flow goes to everything else. You have a flow splitter so you have two flows also.

On the side of my hydraulics that goes to the steering and the drives, the fluid enters a single spool valve that has power beyond.

The power Beyonce outlet goes into a 4 spool valve. Spool 1 is loader up and down, spool 2 is loader tilt, spool 3 is aux hydraulics 1, spool 4 is aux hydraulics 2. Then it's return goes to the tank return header.

The way this works is if I am actively steering I can't move the loader, but if the steering valve is neutral I have flow to the 4 spool valve and all my functions. I figured steering is more important than lifting.

On the drive motor side I only have one drive motor and one Valve. The flow goes to the valve, to the pump, back to the valve and to the tank. Applying this to you your down stream splitter is all downstream of the valve so this arrangement should work. I was under the pressio that your second splitter acts like a positive differential between the front and back wheels.

I'm shocked that you aren't using a a divider of any sort to be able to drive and manipulate the bucket. Love the mini hoe having a separate hyd. system for the loader and the hoe but I had to do it the onboard system just wouldn't hold enough oil. There is still a small cylinder in that system for a 3pt hitch but it'll never get used with the back hoe attached.

That above came out different from what I meant. My steering and loader functions are on one section of my pump, the wheel drive circuit is on a seperate section of the pump. The flows come back together before a filter and dumping into the tank

I have two flows, just the same as Gator's machine, one flow is propel thru a standard 4way cylinder valve and one other flow does the steer with power beyond for the loader..Im so used to running it now I really dont notice the loader not moving when steering like when moving snow,lifting and turning..I can turn and use the loader by 'jabbing' the steer valve to steer in short movements..I just concentrate on the loader movements and steering as necessary..I dont have room for a flow divider in my chassis as its very tight already..I was looking for a 3section pump but that goes to a whole new level of expense..so I keep what I have-it works.FWIW I had the Brand Hydraulics motor valve on my machine fro the propel circuit but broke it permanently so I went back to a standard cylinder valve..

KEVIN!! --- hey,-- can you take some pix of the different sections of the hose and valve parts of your loader and post them? ---You can even e-mail them to Gator, Jim, or I and we will post them for you! This will GREATLY help figure out what some of the problems are on your machine.
Just curious ------ but do you have 4 drive motors or just one? I saw somewhere that cad uses 4. That would require a lot more hoses and give more areas for problems to arise from. Thanks!

I can’t believe y’all don’t have a power Beyoncé on your loaders. That’s the French/soul version of a power beyond.....gives your loader better dance moves.

Honestly I couldn’t tell you one thing she sings. I mostly listed to sports radio and talk radio..

I had typed that on my phone and it autocorrected power beyond to power Beyonce...

I fixed it when I went back to clarify what I meant when Jim questioned me. I saw the Beyonce then...

I have been Talking to Kevin some on FB messanger, he has some health issues that make it difficult for him to get more info. He is working on getting some pics to us to help show the setup.

we've been playing with this stuff most of our life if not all of it. We could probably get it going with ball valves HA HA HA. we really need to see what it has for plumbing parts and how they're all hooked together.

my long winded answer/suspicion was the original builder salvaged the wrong valves and/or other parts to repair it after a problem..replumbed it after 5-6 adult beverages and didnt understand what was going on..it's not that complex of a system..Kevin threw some good money at it for a new pump,which will benefit him if he keeps the machine,and the loader valve is nice as well..move that over to the loader side of the hydraulics and even just put a std 4-way valve on the propel motors circuit and see what happens..check pressures FWIW we'll see for sure

Thank you for your assistance, one and all. I am going to order a new splitter and a new divider today since the divider was never there and there seems to be something wrong in one of the circuits coming out of the splitter that still generates back pressure and heat at the pump. I have a valve I can use (hopefully) to control fwd/bkwd travel that is supposed to be on the floor panel. I will let you fellas know how that works out when I get it done.

I went to put the new flow divider on and it is about 1.5 inches too long to fit where the original is. Dag nabbit! I could bolt in another ,wider, piece of angle iron in or weld a piece on the original piece, so I guess I'll be headed into the blacksmith shop tomorrow or next week for some supplies.

Kevin watch this video.

This one is theory
Hydraulic Basics - 01

These next two will help you
Hydraulic Basics - 02


Hydraulic Basics - 03


After you watch those, you can search youtube for "Hydraulics Basics - XX" with the XX being 01,02,03 etc. Good info in this series. The other videos go into motors pumups etc

Kevin try to get some numbers or model id's off the valve casting and google it-be sure what valve you have you can use with your system. You could also look at the valve photos on SC to possibly match up the vendor/valve series. When you do fire the system up again, you could lower the relief valve setting to prevent any startup disasters-the relief will open up before anything blows up and save you hassle and money of replacement parts..just a thought
Best of luck.

Another thing to consider Kevin is if safe and reasonable you might hook your flow divider up and zip tie it in place before welding new brackets. You should be able to test it that way before you spend the effort to modify it and it maybe not work.

What fun is it if nothing explodes? It should have self destructed in some way with the old pump in it when it was hitting well over 200 degrees right outside the pump!

Kevin at the bare minimum wear a good pair of safety glasses when working with charged circuits and fittings..the fine spray of pressurized fluid can penetrate the skin and cause serious issues with your health. Be careful and use respect working with these systems.

Got a face full one time from a backhoe when a hose broke right in front of me---knocked me off the seat! That stuff shows no mercy!

Considering that just water under high pressure can cut stone....pressurized fluid is right dangerous. Cutting oils and I don't agree too much with my skin, so I do try to keep gloves and a shield between me and them.. I got a new bracket/shelf made to hold the new geared splitter and got the fittings to mate it into my machine. No welding, just bolts on and the new splitter bolts on to it. I thought about the idea of zip tying it down for a temporary fitment, but since it will be a permanent item, I made a permanent bracket for it. Tomorrow should be good weather...wish me luck.

Gloves won't help with a hydraulic injection. If you get a small crack in a hose it can be leaking so small that you can barely see it. That stream will inject through your gloves and into your skin. Google hydraulic injection injuries. Very bad stuff, anter that injection the hydraulic fluid poisons you and they have to split your arm from one end to the other to get it out.

Never touch a pressurized hose to try to check for leaks and if you do and you feel a sharp sting, you should head to the hospital.
