I just found your channel this morning. Good work sir! I've watched both box blade videos and I'm watching the videos in this series now. Thanks for making quality and easy to understand videos. I'm already wanting to make mods to my Kubota.
Dave, I hooked a gauge the all 4 ports in the accessory valves. Each read approximately 2100 when the relief kicked in. Next, I left the gauge in one of the remotes and operated the backhoe (just curling the bucket to full stroke). The relief kicked in at 1400 PSI instead of 2100 when I was only operating the remote valve levers. I guess that would explain why the backhoe is weaker than I expected... Any suggestions? Can I simply open up the remote valve relief all the way? I'm going to have to get a female quick coupler to check the loader because it has male fittings on the tractor side.
sounds like a relief in one of the valves is set to low. try and look up the valve that is located on the rops via google search. the one they added is likely set to low. the instructions will show what direction to turn it to set it higher. a lot of add on spool valves have reliefs that are factory preset to 1500psi they can be set to 3000. setting them high on those valves should not hurt a thing because those valves are fed after the main relief located at the main distribution block via the power beyond port of the loader spool valve. the loader spool valve is likely set correctly. the one on the rops is likely where the issue is. so yes set the relief higher. I believe on most you turn it in clock wise to raise the pressure required to dump relief to tank.
Thank you for posting and sharing your knowledge and experiences. I want to add one to my Kubota and the spool valve just came in. According to the instructions that came with it, I am supposed to connect the power supply to the “P” port. They said to connect the power beyond to any additional valves. It seems you connected you supply power to the power beyond outlet. Did you change it to power in when the camera was not recording, or does your valve work with “P” port plugged off and supplying power through the out port (power beyond). Thank you sir in advance for clarifying this for me. Kind regards, Bud
the valve I had was labeled weird it had a power beyond in labeled with a "C" if memory serves me correctly. and then a back to tank out. then it had a screw block inside that had to be installed or removed I cant remember which. this created a third port which was labeled as power beyond out. your valve should have pretty good instructions so follow those and you should be fine.
Dave, I'm a first time tractor owner with a used B3200 & BH76 backhoe. It also came with aux valve kit that was setup to run a stump grinder. I get a squeal from the aux valves (mounted to the ROPS) when I'm using the backhoe if I hook into a tree root. I've also noticed that if I lower the FEL to lift the front tires off the ground and then begin using BH, the BH seems to have less power. Any suggestions on what to check?
I would get a pressure gauge and check to see what the pressure dumps at. the relief on each valve is set to not exceed max pump pressure to avoid over heating the pump. typically when you reach the dump pressure of the relief it may very well squeal. hydraulics have 2 major components 1 is pressure the other is "flow rate". you can buy a cheap pressure gauge to check the pressure however the flow should be checked at the dealership. may as well let the dealer check both. if the squealing is simply the relief kicking in its no major problem. if its the pump struggling that could be an issue that needs fixing. sounds like the relief in the valve mounted to the rops is set lower than the main relief and is kicking into relief to early. the issue with the fel creating a weak BH may just be your imagination. I never heard of this being an issue. I guess its possible the loader spool valve is worn and needs rebuilding. if its leaking back to tank under load that will divert hydraulic fluid away from the BH. this is all speculation on my part. when I speak to my son again I will ask him he is a kubota repair tech. he may have a suggestion.
that is not very many hours at all. if the sound is coming from the valve that was added at the ROPS then I would bet the relief is set to low and is kicking in to soon. your hydraulic lines design is most likely like mine it goes from pump > distribution block > fel valve power beyond > ROPS valve power beyond > back hoe valve bank power beyond and then returns to power beyond connection back at the distribution block. the distribution block is the first stop from the pump and it has the main relief valve installed to protect the entire system. if any relief valve in the system is set lower than the main relief valve setting then that lower set relief will open prematurely resulting in what your describing. however keep in mind if you have a hold of something like a major root that the backhoe can not break its best that the relief kicks in to relieve that pressure. you could increase the relief pressure setting at the auxiliary valve on the ROPS so it dont kick in so soon and instead the main relief at the main distribution block with over ride the system pressure as it should. keep in mind these tractors are not unstoppable I have seen massive track hoes get stalled out digging roots, rocks and just hard soil. dont expect to much from your machine. its a power shovel and gets tired and hot just like a person would. dont over work it and give it a rest period when needed.
these are 2" - 3" roots probably for an idea in size. I believe mine is plumbed the way you described also. Would I plumb a gauge inline from the ROPS valves to the backhoe using quick disconnect couplers and then the backhoe and see what the gauge reads? How can I find what the tractor relief is set to compared to the aux relief?
you need to unplug one line going to the loader hydraulic cylinder and plug a gauge in there. start the tractor and work the loader valve to send fluid into the gauge. when the pressure builds to the point the relief opens it will read that pressure on the gauge. in other words if the gauge reads 2500 psi that is what the relief is set at. ideally the relief in all valves except the main relief valve should be set high. the main relief valve is factory set and should be the lowest. that relief valve is located in the distribution block under the right side floor panel. the loader valve should be set fine. the valve they added that is mounted on the ROPS is likely set to low. you should be able to safely turn it up to full pressure and not have any worries because the relief in the main distribution block will protect the pump. hope that makes sense. I may show some of this in a video that is coming once I finish all these videos on the valve I'm installing.
with them power beyond plugs you need to add a bit of blue lock tight to the treads, also when buy valves you need to know the GPM OF YOUR PUMP and match your new valve with that rating, failing to do so will over heat your oil really fast
Dave, I'm a bit late to the party here, and am fairly new to tractors. Great video series on adding the remotes. This is something I have been wanting to do to my 2015 L3301 w/ BH77. The only challenge I have is I'm not very savvy with hydraulics. I understand what you're doing, but don't fully get what lines are being used for the pressure connection. And then what you mean by interrupting the Power Beyond line. Could you post a diagram of how you plumbed it maintaining the connections for the BH77? Again, thanks for the great videos.Bob...Wa State
First video was better. You’re re routing hoses and cant see anything. Making brackets and not showing. Just makes a big gap and hard to follow. 10 minutes tightening a fitting and all the important stuff nothing
yes you get caught between trying to make a video and trying to get the job done and something ends up lacking. just let me know what you want detailed pictures of and I can email them to you. send me an email to Daveknowshow@aol.com I will help you the best I can.

thanks for stopping by! I hope to make a few more quality tractor videos coming very soon!
Hi Dave. I'm here but I'll watch this another day, it's getting late and I have to work tomorrow. I'll be back!
no problem it will be here maybe a few more

that makes perfect sense Dave! Thank you! Now, how do I identify the valves on the ROPS, as I don't have any paperwork on them.
should be a part number embossed in the metal just google that part number may hit.

I bought it with 78 hours on it last month and now have 90 hours if that helps.

Where did you order the valves from
northern tool and hydraulics, at my local store. there are many places online with them
with them power beyond plugs you need to add a bit of blue lock tight to the treads, also when buy valves you need to know the GPM OF YOUR PUMP and match your new valve with that rating, failing to do so will over heat your oil really fast
as long as the valve GPM is larger than your pump you will be fine.
appreciate the input thanks for sharing with us, and for watching the video.

I will be happy to Bob! I have to drop the dog at the hair salon but after I get back I will do a more close up video of where I tapped into the line
video is up!
Harbor Freight Pittsburgh same as kolbart
lol your likely right!
