You can try it out. It should work if the Ls system to which you connect the valve is static and does not need pressure discharge to the T line
Manual steering works fine, and has from first start. I’ve tried about 3-4 times now. However, I just found out about the manual overrides on the valves. I pressed on them and they seemed a bit sticky. I never tried starting the tractor after that. I’ll have to try actuating those again next time to see if anything has changed.
I turned the relief valve adjustment; do I need to be concerned about getting that exactly back to where it was? What about the compensator valve? Is there any adjustment on that one?
It seems like there’s no flow getting to the proportional solenoids and it’s all still going straight through to the orbitrol. Maybe debris is stuck in the compensator valve? Would that make any sense based on the behavior I have described?
How difficult should it be to press the manual overrides on the proportional solenoids while the tractor is running, and auto steer engaged? I can hardly depress them at all with a T handle Allen wrench.
I also loosened the solenoid coils and set the PWM up as high as I could in the steer config menu. I could easily overcome the force of the coil and pull the coil off of the valve spool.
The force required to actuate the overrides vs the holding force created by the coils doesn’t seem to match up. Maybe I’m not getting enough current to the coils (electrical problem), or maybe they’re too hard to actuate (hydraulic problem).
Thoughts?
Hi baraki… I have emailed you several times last months. I Would like to order a valve for a fendt 209 f vario. You promised me to find out wich one we need. Would you please look at this again ? And answer my mail please ?
Thanks! Guido.
Which valve version for Kubota M7060?
It is quite difficult but not impossible.
Does your tractor steer when you press one of the sides?
Does your tractor not respond when your settings is like this (all red circled are green)
Please post a picture of your screen with almost same settings
A standard 30l OC valve will fit.
Hey @baraki, I asked you awhile ago about a steering valve for a JD 4755. Does it take a special valve, or can I order one from your store? Thanks!
So I started swapping around hoses to see if I could learn anything. What was interesting was that I could get auto steer to function by swapping the P and T hoses at the valve. I figured out how to work the steering screen while doing this, and proved to myself that everything is working fine electrically. I can move the steering left and right with auto steer engaged within the steer screen.
However, doing this made manual steering non-functional. I think that by sending the pump flow through the valve’s T port I am bypassing the compensator/logic valve, and sending full system pressure to the proportional valve on the block. When it’s closed, the steering systems relief valve is then sending all that flow to tank so nothing can supply the hand pump.
This of course is not a functional system, but is it telling me something about the compensator valve? Is it stuck, or not demanding flow to the proportional solenoid when it’s connected properly?
You have OC system.
If you connect p to p on steering valve and t from steering valve directly to tank, then the valve spool inside proportional valve move to one side and let oil flow direct to tank (kind of backwards)
You can check this situation by pressing both (engine not running ) manual actators in , they stay in about 3 mm. When engine is started and oil flow you can observe one actuator had come out and the other is still in. This should not happen when valve block is in series with orbitrol.
Ok. Thanks.
But on github you tell us that we need a special valve for fendt… A " static" valve.
So this is not a standard oc valve i think…?
What is the difference between them…?
Do you know what type of connection i need for my fendt ?
Thanks for the response, but I’m not sure I understand.
I have an OC Baraki valve and I know I have an OC system.
What I can’t figure out is why it seems like there’s no flow being directed to the proportional valve when everything is hooked up correctly (baraki valve in series with hand pump).
Should some oil leak out of the little screw plug on top of the compensator valve when I unscrew it with everything hooked up correctly, and AS engaged? I expected there to be, but nothing comes out. That should be the same cavity as the valve’s internal “LS” line, right? Does this indicate that there’s somehow no oil getting to the LS port/orifice of the valve, and therefore no way for the valve to shift any pressure/flow to the proportional valve ( all flow is getting dumped through to the hand pump)
You MUST show us a drawing of hoses and name Ps and Ts in your system. Because I do not understand how you have connected things.
Hopefully this clarifies things. I have included an image of the tractor hydraulic schematic, the valve’s connections, and the hand pump’s connections.
When everything is connected as shown, I get fully functional manual steering, blocked flow/locked wheel with AS enable, but no function of the proportional solenoids.
When I reverse the hoses to the P and T ports at the Baraki valve (red and pink, not shown, but I tried it), I get the proportional valves to move the steering (using the steer screen and/or the Cytron override buttons, but no manual steering.
I remembered that you asked about the Fendt 200 some time ago, I then downloaded the service book and checked the steering system in this tractor and I am sure that I replied to your message. Fendt 209 has orbitrol OSPEDC 60/100 LSRM (Danfoss) or LAGU 100/50-13/LDAR220-160M40-559S (Bosch Rexroth) both types are Ls but there is a priority valve screwed to the orbitrol from which there is no Ls output so the only possibility is use an OC valve connected between the gear pump feeding the orbitrol and the priority valve mounted on the orbitrol. This is the same solution as in the Fendt 300 series, with which the OC valve works very well.
The connections are correct. Do not interchange P and T hoses as this may damage the pump. Perhaps the compensator does not work properly, it is not adjustable, but try to unscrew it and blow it out, there is a very small hole on the side under the thread that could be clogged.
I see at the fendt page that it is from a 200 vario S3 !!
I do not think mine is a S3 … He is from year 2011 or 2012 i think that is not a S3
Do you stil think de oc valve is ok?.
Tomorrow a send you a schematic of the hydraulics of mine 209.
That might help, because you describe oil coming from priority/flow divider valve to steering valve. And baraki describe oil coming from pump to steering valve.
Yeah I’ll try that. I had the compensator out already earlier today, and noticed that tiny hole. I didn’t blow air through it, so I’ll take it out again and do that.
Is there any other possible place the oil could get blocked from getting to the compensator sense port?
