Martin, thank you so much for the shout-out! I REALLY appreciate it buddy! :) - David
My pleasure, David. Dave of Dave Knows How did this for me early in CZcams channel days and it made a HUGE difference in my channel’s growth. I hope you get a big boost in subscribers as well!
@@DIYMyWay I hope that my channel will grow large enough that I can pay it forward one day to another up-and-coming Kubota channel! Blessings my friend! :)
Hope you do a shim video! I’ve seen others but you make videos that are easier to understand and use. Keep up the good work!
I probably will make a shim video before long. Thanks for the kind words!
Here here! A shim video! You are so talented Martin!
Always a pleasure to see a new DIY My Way on the feed. David from Pale Horse does an amazing job on his videos. This is a good video as i see lots of people on forums concerned about their lifting capacity.
Thank you, Richie! Yes, David makes quality videos for sure. I’ll probably make a video on shimming the valve to boost the PSI before long. Thanks for watching!
Thanks Martin.
Have not checked mine, but will do this soon.
Thanks for sharing!

Thanks for watching, Kenny! Good luck checking yours!
Thank you for sharing Sir. This is one item that I question from time to time. I should check my PSI. Have a good one
I recommend you checking it occasionally. It’s been a couple of years since I checked and as I recall it’s reading about the same as last time. Thanks for watching!
Hi Martin! You read my mind! I was wondering how to do this recently. Thanks for sharing!
Your welcome, David!
That will help a lot of people Martin. Like always very well done video. Have a good week! See ya!
Thanks, Jon! I hope you have a great week too!
You are my go to guy for D I Y fixes thanks so much. You are clear and consise in your explanations
Thank you, Ralph! Glad my videos are helpful to you. Thanks for the visit!
Another awesome video Martin! So good that Bolt On is now sold out of that same pressure gauge that you bought!
Thank you, Michael! It’s nice to think my video helped them sell out of the pressure gauge.
Great Video! I have not checked the pressure on my tractor. Its on my list. Nice lead on where to get a gauge. Thanks!
Thanks, Marty! Hope your tractor is up to spec when you check it!
Great video...Ken's bolt on hooks is an excellent company. I look forward to your video explaining how to get increased pressure, as I don't have a clue as to how to accomplish that, thanks, Bob
Thanks, Bob! I’ll probably make a video on it before long.
Yes. Thank you I asked this to you along time ago.
And I finally got around to it. Hope you found it helpful. Thanks for watching!
Thanks Martin. I have been very happy with the performance of my L2501 and never felt the need to check it. It would be interesting to see just how close it is to specs.
Hi Gary! The gauge isn’t very expensive so you might find it worthwhile to get one and find out. Thanks for watching!
Great product! I've mounted a gauge permanently to my tractor, linked to the "raise FEL" hose. So when I do max out the lifting capacity, I can confirm my Case is to spec with 1300 psi (Yes, that is low!). But the best function is to estimate the load being lifted too. The value is only good when I am rising it from and close to the ground, which calculation is as follows: (PSI reading -350) x 2 = lbs lifted. Although the 2 factor is a rounded number, the exact value is close enough for estimation. That is just luck the conversion factor gave that simple number, as it was based on triangulation of forces, leverage, size & number of cylinder, etc. Thanks!
Hi Joe! Yes, the PSI is low, but I’m guessing the gallons per minute flow rate is decent and your cylinder bores are larger to make up for the low PSI. I’m not surprised you have a permanent pressure gauge on your tractor and have worked out the equation to calculate the load on your FEL in pounds. Of course you did, your’e and engineer! LOL! Thanks for watching!
I do have 7gal/min, which is not too bad, but the bore is still 2 inches in diameter. The difference is that the stroke is longer... Beauty of hydraulics!
Great video...
Thank you for sharing
Thanks for watching!
Both my old 2501 and my new 3902 hydraulics were under specs! I bought the shim kit off eBay for $18 (already had a gauge)
I went 250 psi higher than spec! (Right about 2500 psi) I rarely use max lift pressures so not concerned with damaging the hydraulic system …But if I do need it ..I know it’s there! I do need ballast when lifting something that heavy. Some where around the 1300-1350 lbs area! Before it would only lift 1100 lbs or so.
Great video as always.
Hi Mark! That’s a mod that’s on my list to get done. I could use a little extra lift from time to time. Thanks for watching!
Very informative Martin, nice job. Does BoH provide any idea as to the expected accuracy/variation of the gauge? Thanks. - Chris
Thanks, Chris! Not that I know of. It would be nice if they offered a digital version of the gauge. Thanks for watching!
Very useful video. I have a L39 Kubota which I am currently starting to test hydraulic pressures. I am wondering if there is a master PRV at the pump outlet as well as at each control lever?
Glad you think so! There should be a master PRV for sure. I believe most hydraulic implements like FELs and backhoes have their own PRVs for each pair of spool valves. Mine do, anyway. Thanks for watching!
Question I have a bobcat. Arm won’t go up and it won’t dump only moves forward reverse. I conected a have on the hose coming out of pump main pressure and reads only 500 psi. At hight idle
Thanks Martin. Shimming myB2650 was a breeze as well. Occasional testing is good, as the pressure spring can weaken over time. Bolt-on has all the shims one will need to maintain factory specs. Warning,be prepared for the “it’s ok to over pressure the system” group should you make the follow-up video 😎 Take care my friend.
Hi Paul! I didn’t know BoH has the shims. I’ll check it out! Thanks for watching!
@@DIYMyWay Sorry Martin, believe I had a senior moment there. I purchased my kit from Bxpanded and it came with a selection of shims. I don't see the shims listed individual there now. I do know my :Kubota dealer has all the different sizes. Many sites offer on-line sales as well. Sorry for the confusion.
No worries Paul. I know I can get them from my dealership or Messicks.
nice job showing how easy this is to do...and relatively cheap
Thanks! Yes, it is easy and pretty cheap to do.
Great video Martin. Now you have me curious what the pressure is on my L3301. Just ordered a gauge from bolt on hooks.
Thanks, Frank! Good luck with your pressure check!
Ha! That's why BoH is now out of stock.
Good evening Sir 😊👌 Great hydraulic informative video 👌🧐 FULL WATCH and have a GREAT WEEK END Sir 👌😊 Cheers 🍻
Hi Dave! Thank you, sir! Have a great weekend too!
@@DIYMyWay 🍻👌😊
I am getting ready to check my pressure now. I bought the hose kit like you have. Am I supposed to just move the loader lever or hold the loader lever the whole time I’m checking the pressure?
Hi Mike! Hold the lever the whole time you are checking the pressure. Thanks for watching!
How's she goin'? David at Pale Horse Outdoors is a pretty nice channel eh!!! He does a nice job with his videos. This was a nice video too!! This is a great idea for testing the hydraulic pressure. I know on my Massey Ferguson GC2300 it seems like it doesn't have the power it did when it was new. Perhaps the hydraulic pressure is just low. Thanks for sharing this method of testing. Take care!!!
Hi Mike! Sounds like you should check the pressure. Those springs in the pressure relief valve can get fatigued over time so you might find you need some shims for it. Thanks for watching!
@@DIYMyWay Yes Martin that could be the cause, but maybe my pump is wearing out too. That would be a pricey fix. So like the guy says, "Never ask a question unless you're prepared for the answer." So I'm holding off for that reason probably!!! LOL
Thank you, Mike! :)
If I am trying to find the proper RPM to idle the engine at for a pto hydraulic driven attachment, would this tool function well to test and find out which RPM is going to meet my needs? This is kind of a DIY project where the attachment isnt exactly designed to be an attachment for a tractor but does require hydraulic pressure. I know the limits of my attachment but I am struggling to find specific information on the pressure outputs.
Supposedly, the hydraulic pump pressure is not very dependent on the engine RPM. The engine RPM does affect the gallons per minute of hydraulic fluid that flows. The max pressure is controlled of the relief valve of your tractor’s hydraulic system. Your attachment SHOULD have a pressure relief valve of it’s own to protect it from over pressure but if not, you should add one. Will it be running off some rear remote ports or 3rd function valve?
Martin, we both have a Kubota L3901. What is the gal per min on our hydraulic pumps?
The main hydraulic pump is 6.3 GPM and the power steering pump is 3.8 GPM.
Ibought the gage a long time ago but have not tried.
Sounds like you should dust it off and give it a try. Thanks for watching!
do you have a vid on your hydraulic top link?
I don’t have a hydraulic top link so I don’t have a video on one. Thanks for watching!
3:44 How are you starting the engine without sitting in the driver's seat and pushing the clutch?
My tractor doesn’t require the clutch be pressed to start the engine because it has an HST transmission. Thanks for watching!

Pleased to meet you, Old Nortrac. You can call me Martin. Thanks for watching!
