Kubota BX 2370 hydraulic pressure relief valve adjustment

Quick easy way to upgrade your hydrauilic system to get a little more out of your loader.

[@paulkennedy5782]

This is so well done that I am asking you to do other videos. Your voice and discreptions is perfectly done. Many Thanks

[@seansysig]

Good video quality & content. Also good explanation of pressure increase adding 5 tenths of shims to increase pressure by 225 psi. Also the added safety reminders are very appropriate! Keep the content comming.

[@brianminghella3312]

Tempting, very tempting, but on a tractor this small I resisted because my property is on a slope and i dont want to shorten the life of the pump. Still, a useful video and thanks for sharing the info. I just replaced the four steel banjo lines from the valve body out to the hose outlets. All blowing oil at the O rings. So I reckon I am already operating the tractor right at its limits. Mine is the same model/year as yours. BX 2370. I have shifted many tons of dirt with my loader. Probably at least 400 tons. The problem over time is that the back pressure on those lines especially the main pressure line to lift the loader frame, was just to much for the Banjo Seals. Not even viton O rings fixed the problem. Also blew the braze on one banjo twice. Not worth trying to fix, even with silver solder. So far so good on the rubber replacement hoses. Watch out for your banjos because you may not notice the leak until its to late. When they go they go bad. Its a stupid design in my opinion, the banjo’s just are not heavy duty enough. Cheers.

Hi jeff, ty for posting this, I bought the Bxpanded hydraulic pressure tester they sell, I like yours better, my kit came with 3 shims, a 1 a 2 and a 3, I think I will use your part #'s and get thoe shims since they are made by kubota. Again ty for posting

[@goneredcar1]

Thanks Mike My local dealer had them in stock and about $00.65 per shim. I did run mine up to 2000 psi and the other day I had some freight show up on the tailgate of a truck. The freight was 470 lbs. I had my bucket forks on and lifted it without any problem. I was very careful lowering the load before I moved and keep it as level as possible, it work great.

[@Northeast_Mainiac]

I have to get to my local dealr and buy these, I wonder exactly how many of the spacers I can actually put in there?

[@goneredcar1]

After you take your first hyd reading you can determine your shim amount by .1 MM per 45 psi you wish to raise your relief valve pressure. The factory sets the PSI around 1700 to 1750 So do the math.

[@Northeast_Mainiac]

What is the maximum you would go to?

[@goneredcar1]

I can only speak for what I did and that was 2000 and the machine seams fine with that. The reason I did it was I use mine for moving pallets and close to the ground only. I just needed a little more lifting power and they now lift without fail. I would also recommend always use the appropriate ballast whenever you use the loader, be safe.

[@OrganicToon]

First of all THANK YOU for this video!!! I just have a couple of questions: 1. Where did you get the hose and gauge set up? 2. What is the size of the coupler needed? 3. Do you believe that this would work on the bx2380? Again thank you for your wisdom and efforts and have a merry christmas!

[@goneredcar1]

Got the gauge off ebay for $9.00 hose from Farm And Fleet $8.00 ,and just matched up the coupler there $6.00. I'm unable to answer your question if the 80 and 70 are the same. I can say previous models were the same, check with the dealer.

[@wrecker1861]

[@goneredcar1]

Check your hose connectors

[@goneredcar1]

No not necessary to bleed air from the hose. I did however bring up the pressure slowly at first so the gauge didn't get banged.

[@jamesdaidy8223]

I was lifting a heavy log with the bucket and now the bucket won't tilt down fast. Any quick fixes?

[@CantNotDance]

good instructions. very clear.

[@jomarsaguing8877]

sir can you upload some videos of BH-06 KUBOTA ECAVATOR AND HOW TO TROUBLESHOOT. like a hydaulic problems

[@ramosel]

Did you pre-fill your hose before you put he gauge or the coupling on it? Any air in there could throw off by hundreds of pounds PSI. My BX has almost 400 hours on it and still puts out over 2000PSI on a bled gauge and 1790PSI on a 20 inch hose with air in it. The high/low bypass relief pressure should really be done on the three ports(one for low) on the bottom of the trans... around 3000 psi.

[@SimpleLife1971]

Great instructional video! I've been looking for a way to increase the lifting capability of my front end loader. I've researched adding larger hydraulic cylinders and while this is more than doable, the shim change is a lot quicker, easier, and much less costly. I see the stock setup is configured with one solid flat shim and one flat washer. Knowing that by adding a shim simply changes the preload on the valve spring slightly therefore increasing the fluid output pressure, I'm wondering if adding a 0.5mm flat stainless washer on top of this stack would result in the same performance change? Comments are greatly appreciated!

[@PeterMcGuire]

Great video, thanks.

[@BigLarge127]

Well done video, thanks for sharing. How does upping the pressure 225psi trabslate to real work lift numbers? Also, why doesnt this affect the 3PH?

[@goneredcar1]

BigLarge127 Not a lot of extra pay load of lifting but as they say every bit helps. The 3p is on another hydraulic circuit.

[@jeffreid3341]

around 200lbs

[@xdude2x]

I believe roughly 125psi increase = 75 lbs lift

[@BiffsEquipment]

I made a video further explaining this process also. Check it out if your interested

[@genesmay6589]

They told me this voids the warranty so if you have one remove it before service if you break something.

[@robertdonnelly7897]

It wont void Tractor Insurance

[@SimpleLife1971]

I just ordered 2 of each from Messick's for less than $10.00 shipped to my door.

[@goneredcar1]

The shop manual for the specific model will give you the description of the complete hydraulic system that you are looking for.

[@joebutner8118]

Great video! I have a 2019 BX23S. What pressure does it come to the factory with (not mine necessarily, but yours)? What is the highest pressure it can be shimmed too? I am not clear on where you attached the hose. Did you take a line off and install it? If so what did you do with the line you took off, plug it? Can you just leave the gauge on permanently to monitor pressure? Is 200 lbs of additional lift really noticeable?

[@goneredcar1]

The pressure is listed in the tractor manual for your specific model.Joe Butner The pressure was low on mine and the shim addition made a substantial difference.

[@beverlygolden9893]

Great video and thank you for taking your time to post something helpful like this I have a 2010 BX25 do you know if the relief spring set up is the same as what you are depicting in your videoThanks again

[@goneredcar1]

+Don V I'm sure that it is but, you may want to confirm with your local dealer

[@cmeador1984]

good video! I have a BX25 2009 that has been worked HARD I'm curious what the factory spec is? I haven't tested mine yet to get my baseline, but I'm willing to bet my pressure is low.

[@timfrance1934]

will this burn out the pump and blow the lines plz respond

[@paulmcyr1164]

I did this mod to my BX25. Upgrated to a B2650 and was wondering if it was possible for my new tractor

[@FrickTruck]

I have BX2380 with quick connect manifold. Can you disconnect the manifold and still use only one outlet?

[@goneredcar1]

Sam Simpson I believe as long as you can safely adapt to the connector and gauge. Also check in the service manual for model specific pressures to confirm.

[@larryrobertson3310]

very good !! i bought a BX25D about a year ago and that is the cheif complaint is not having that great of a front lift capacity !!! thanks for the info . has it effected the life of the hydraulic pump ??

[@goneredcar1]

The hydraulic pump is rated much higher then the regulator pressure

[@thomascrawford9909]

I Grew up on farm equipment. All pressures and RPM of all tractors are set there for a reason. You could run it full throttle at full spec pressure and never should anything be damaged from it. I would climb in my 4455JD and (10 yo boy) Fill with fuel check fluids and run that full throttle for 14 hours plowing and only stop to pee. It would be looking for more fuel by then and me some sleep. I have always been told be all diesel mechanics, WORK THAT DIESEL, it was made for it.

[@Stevesmith-di5ke]

opening up the hydraulic pressure will this make the Kubota go faster for speed

[@thomascrawford9909]

not faster, just more hydraulic pressure. Lifting and the hydrostatic tranny would be stronger in each gear. But not faster.

[@holliemeckler4413]

does it matter which order i install the shims?? pleas add that to the video. thanks!

[@thomascrawford9909]

order does not matter. Each shim is a different thickness and pressure increase. Do not add to many and cause to much pressure increase. You have to check thickness and each one is different(at least my kit I bought is assorted thickness,colour). Check pressure gauge, figure out how many PSI increase you need and add shims accordingly.

[@harborcbs]

I know this post is a bit old but just a quick question on your gauge setup. did you have to fill the hose with udt or did you just attach everything dry? I wonder because i'm worried about the air in the hose compressing and giving a bad reading. Thanks for the video.

[@thomascrawford9909]

I actually have same gauge but without hose. Fit directly to loader valve. I think it would still just read the line pressure, air would not matter. If you think it matters bleed it by , very carefully loosening hose at pressure valve at tractor IDLE and tighten when you see oil leak out. It will always stay filled with oil. 2000-2500 PSI so be careful. I would loosen it a bit THEN start tractor, move the valve and let it fill and shut off tractor to tighten. Just to be safe. If you don't have any know how in this, DO NOT TOUCH. Let the dealer do it for you.

[@caryhubbardfamilychannel7516]

Thanks for sharing this video. I just gotten my BX25D about a week ago. I wish it had little more power to it. Will it help the backhoe too? If not, how can ya up the backhoe too?

[@goneredcar1]

+Cary Hubbard It affects all pressures that are associated with the hydraulic pump. It has been reported that some original pressures were around 1600 psi. Make sure you confirm your pressure with a reliable gage before attempting this procedure. Remember you are only bring the pressure to the specs your not exceeding them. You may also review this in the shop manual stay safe.

[@caryhubbardfamilychannel7516]

+goneredcar1 Thanks buddy, appreciate your help. I will let ya know how mine turns out if you like. I may do a video on it. Thanks.

[@goneredcar1]

+Cary Hubbard please let us no how it goes. This may help others in doing this procedure.

[@johnregal5098]

Did you replace the old shims or add the new ones to the old shims?

[@goneredcar1]

John Regal Just added to the existing shims till the pressure reached the target pressure.

[@bombidude]

How much more lift capacity do you think it adds?

[@rvkubotaman]

Goner, I noticed you have your mower deck standing up, is any oil from the gear box leaking in that position. I put mine like that and after months it had leaked some oil out, if yours didn't leak I need to check my bolts to make sure there tight.

[@goneredcar1]

rvkubotaman It’s been hanging there for two years no oil at all.

[@rvkubotaman]

Ok, I'm going to look atmine again, my deck is new never been used, takes up less room to store, ok thanks.

[@goneredcar1]

rvkubotaman There is one difference mine is a finish mower deck if that makes a difference. The deck was only used a couple of times until I received my zero turn mower. Good luck

[@rvkubotaman]

I wouldn't think that would make a difference, I need to check all the bolt on the gear box something must not be tight enough and oil leaked out. I like your video on the shims, I got my gauge and shims but have yet done this to mine.

[@thomascrawford9909]

you may have a bad seal.

[@robertdonnelly7897]

How exactly did you put the shims in? Did you put the original one back in?

[@goneredcar1]

Robert Donnelly Leave the old ones in and add what you need to bring you up to the designated amount.

[@robertdonnelly7897]

Thanks man

[@Northeast_Mainiac]

jeff, did you also add the .4 and .1 to the shims that came in the hydraulic port that was shipped with your tractor? or did you take the originals out and just add the .1 and .4 ? thanks, mike

[@goneredcar1]

Yes, leave the ones that were in the machine alone just add to them till you reach your target pressure.

[@Northeast_Mainiac]

You have been a huge help jeff, I just ordered these shims from my local john deere / Kubota Dealer, thanks again, I have to wait 3 weeks befor I can try this unless I want to pay $15.00 for freight! Thanks again, when I do actually do yhis I will let you know the out come.

[@dmonschangeu1805]

Did you just put in th .4 &.1 or did you add them to the ones that were in it?

[@goneredcar1]

Dmons Changeu They had a .2 already in there.

[@ItsaboutMakingnotBuying]

Would you know were I can buy a hydraulic pressure gauge and coupling for the new Kubota BX 23s they have a new coupling system? Thank you.

[@BigBoyToyzz]

how many more pounds do you think you can lift after the upgrade?

[@goneredcar1]

I would guess about 100 Lbs. but the downwards pressure helps big time while digging.

[@jeffreid3341]

more like 200 lbs

[@CraiglistErd]

I'm not really concerned about lifting more weight with this Mod. but I can't stand how SLOW my bx25 backhoe moves. Will this Mod, speed up the movement or is this simply a lifting power Mod? Thanks.

[@YooooouKnowwwww]

I dont have a bx model but I'd guess that this would not help. This helps with the pressure, which would affect how much it can lift, and not the flow, which would affect how fast it would move. Let us know if you did the mod and it helped though!

[@Sparkynutz81]

what's diameter of shims if I make my own with hole punch or scissors?

[@goneredcar1]

Ryan Meyer check the video the part numbers are all listed your dealer will have them pre cut, I payed $6.00 for all the sizes had them in stock not worth the time punching them out.

[@Sparkynutz81]

@@goneredcar1 $6 plus a trip to dealer for 2c worth of shim stock I already have in various thickness is definitely worth the 10 seconds it takes to punch a few out. I'll just measure the original ones once I take them out. hopefully I have some stock to measure. Some tractors don't.

[@danx8552]

How much hydraulic fluid did you lose during this process?

[@goneredcar1]

Not enough to even be concerned about.

[@cristianosilva6052]

40lb per 1mm 4mm=160 +1mm=200

[@jakeesmart5250]

How high can you go and why not get as much as you can out of your tractor- I'm guessing lawyers are what led to the reduction in full pressure from the factory otherwise there wouldn't even be the option to increase pressure.

[@goneredcar1]

You hit the nail square on the head. When you start increasing capacity you must do it with extreme caution not everyone has that ability.

[@thomascrawford9909]

blow hoses and break cylinders if pressure is to high.

[@jasonthomas1817]

is that the same job for the BX 25D? if so where can I get the shims?

[@goneredcar1]

Same as 25D, shims available at you dealer.

[@jasonthomas1817]

my dealer are saying that mine , the 25d cannot be adjusted up??? are they full of it and just telling me that??

[@wrecker1861]

@@jasonthomas1817 your dealer is dumb.

[@ericbender2267]
