I have the same machine also. You are putting out some great info. Thanks. For anyone interested. I bought the rake, auger and ripper as accessories. I highly recommend the rake. It has turned out to be awesome. I clear brush and pick up logs with it. Great for home use.
I use a rake for cleaning out the compacted straw and orchard grass (mixed with poop and urine) from our sheep sheds...and it's a back saver, for sure. Before getting a mini-excavator, we struggled to keep up with that by hand or rented a Dingo if we got behind. The digger with a rake works so well.
this is a really helpful video for a not-mechanical person like me. I have a Rippa and it doesn't have a temp gauge - for anything! I am in a hot climate so have only been running it for one hour max in the cooler parts of the day. Is it possible to add a gauge in? I'll be following to see you add cooling fan too 👍
Thank you for hitting the answers I’ve been looking for on these machines, I’ve been watching the reviews but nobody really answers my questions about the hydraulic circuit. Fluid power is at the heart of any machine it’s part of. I’ve been contemplating picking one of these machines up for a while.
Think that it is still open centre...ie no actuation fluid goes straight through block...love your channel....amazing they don't come with cooler and filter,that would definitely shorten its life....just sitting digging it wont heat up much,but travelling it will.When adding cooler make sure your engine has enough recharge current to run the fan,some of the cheaper motors don't recharge much.
Thanks for the great video. It helps my understanding of my machine. I do have s question if you can help. I have an agt qh12 with less than 15 hours on it and it has become increasingly weaker to the point where it doesn't have the power to steer. I have turned the preasure relief valve up and get a max of 800 psi. Everything works just weakly. Im thinking the preasure relief valve may be bad. I can find pumps online thanks to you ,but have no clue what valve, or type of valve, or the type of pocket the valve goes into. Ive looked online but no luck. Would at least help if i even reall knew what i was looking for. Thanks again.
at around the 10 m9n mark you said they dont come with a hydraulic filter.i thought the same thing with mine but after having to take off hydraulic tank i discovered a intank return filter and a screened outlet filter.pain in the but too change. Not the same machine but worth the look.
I have the same machine, thanks for a great video, very helpful, do you know is it possible to add an extra auxiliary output to the dcv, ideally foot pedal controlled?
thanks again for videos. Lookig forward to finding out what cooler and filter adapter you choose. Im looking at them now and there seems to be a big selection to choose from. I plan on adding both to my machine as well.
when you do this video can you provide links for the parts you buy? i just stumbled across your page and im loving this content> im learning about issues i didnt even know about> @@thegarageconnection
Have you had any problems with air getting into the hydraulic system? My H12 hydraulic pump started groaning after 3 hours of use and there are a bunch of bubbles in the hydraulic tank that I can't seem to bleed out.
I have the exact hydraulic pump on mine but within 2 hours the o-ring let go just in front of the 4 black bolts. I can't source a new o-ring anywhere and would now like to just replace the pump. Does anyone have a link to a pump that would work?
Great videos, I have the same excavator and I have been following your videos. Just one comment. The hydraulic system on these units are actually open center. That means if there is any fluid not being used by a function (cylinder, track motor, etc) it returns to the tank without having to pass over a relief valve. The spool valves are closed center for A/B ports only, so when the lever is not being pulled the two ports attached to the spool are blocked so the cylinder or hydraulic motor will not move. The A/B ports are closed but the P (Pressure) port is open to pass fluid to any other valve in the manifold. If no valve uses the fluid it simply goes back to tank. A closed center system always has full pump pressure on the feed lines to any valve in the system, the pressure is held back by a machine relief valve. I think only John Deere commonly uses a Closed Center Type System.
Thanks for the reply. I’ve been thinking this over for a while now, and I can’t see how the excavators would get away with a tandem center DCV, because all the pressure in the system would simply dump back to the tank, and would never be put to work in the linear actuators. Then again, an excavator valve manifold is quite different than a normal hydraulic DCV, but the original question I got was asking about them being a floating center, and causing a freewheel with the track drive motors.
Yes, the system is usually referred to as an open center system, as 85dohc describes. More accurately, it is a tandem center system since the valve spool, when in neutral closes off both work ports. In a true OC system, the center AND the work ports are open to the tank. The "freewheeling" problem with going downhill is not really freewheeling. It only feels like that cuz when going downhill with the drive levers actuated, the machine will go too fast. BTW these are quite normal and common open center valves used on millions of tractors. Closed center valves are common on larger equipment that uses piston (not gear) pumps.@@thegarageconnection
Hello my friend, thank you for these wonderful videos I have a mini bagger JCB that has a triple gear pump on it. I replaced it with a gear pump with one inlet and one outlet. I combined the oil outlets together, but the machine does not work unless I use two movements together until parts of it work. If I replace the hydraulic control unit that you were explaining in the video, will it work Please explain, thank you
Thank you so much for this video, if you dont mind would like to ask you something, bought a 2 ton , number 20 , kubota D902 , but sometimes if the bucket gets stuck the machine goes off , could this be related with the hydraulic pressure release valve ?
let me ask you something, i got one of these mini X recently and it has issues , it didn’t have much power and when you move something let’s take for example the boom up and down the engine sounds like it’s maxed out under heavy load and i my thinking was that going down it shouldn’t even do that because the weight of the whole arm it’s already putting pressure down so it’s technically just letting the pressure out one side , so i had an idea and made a test , i took both hoses off the boom and connected the together in a closed loop with a TEE and a gauge on it , when i worked the lever the pressure on the gauge gets to 2500 or 2600 psi where i think it should be near nothing since it should be going right back to the tank so i think it’s fighting 2k plus pounds just to move , what do you think it’s wrong with it ??? I think it’s the DCV assembly sending pressure to both sides at the same time
I just bought this same machine. It's a new machine and it's never worked right. I can get everything to function but with no power. I pulled the relief valve out and it appeared to be functioning fine. I think my pump if fine but not sure. Is their a way I can test it. I've drained the tank and checked the tank screen for blockage. Added new fluid and still nothing. Any suggestions?
I just bought a agt h15 with side controls. Just swapped the hoses to John Deere and now controls won’t work. Noticed a light on what I think is a safety hyd switch on a hyd block under the seat. Now that light doesn’t come on. Is it the switch or air in the system?
I have a L12. After watching your videos I found the oil cooler, pretty obvious, pretty awesome. I can't find the oil filter though, is it inside the tank or something maybe? The tank has a 3-4 inch round cover on the side of it near the cap. Impossible to access easily, and can barely see it, but it is there.
I just received my agt dm12-c today but there's a problem. Evidently somebody hit a drive motor hydraulic fitting with a forklift and sheared off the nipple on top of the adapter going into the right drive motor. The hose looks salvageable but that large hex adapter is toast. Any ideas of what the thread patters (2) are? Fun stuff.
Great comments read them all, im diving into my new to me QK16RSX-C so far from your videos, i have changed from ISO to SAE . Wow, what a difference. i don't have to cross my arms to operate anymore, lol. Also, I watched a few of your other videos and will watch more. I found what looks like a filter bolted to side under floor, kind of an inline filter. Not 100%. It has an oil cooler with a fan. This unit came with AC mounted to the side of the window area. I will re watch your video on the charging system. With AC, i believe it will need more power to maintain battery voltages. Thanks for all the great videos. I know it's a lot of hard work.
Good luck on your duty tour brother... Is there a way to be able to slew and use the DCVs at the same time and not slow everything to a crawl? New dcvs? New pump? I've been told I can put a US-made Parker pump on mine (YH-20), any bonus with that?? How do Bobcat/Kubota mini-x's handle this?
I have a MP 15 mini excavator Incurred a problem after working the machine pretty hard When the engines cool in the hydraulic oil is cool excavator runs pretty normal after a short period of time it quits moving I won’t be able to move any of the functions including the blade. I have checked the pressure relief and it seems normal I got less than 100 hours on this. Any suggestions on what I should do next?
I have the 2024 QK18RXS-C with the 13.5hp Briggs and Stratton gasoline engine. The issue I’m having is the bullseye gauge only shows level not temperature and unfortunately I fear I’m having a cavitation issue. My fluid is getting hot and I’m losing power. Everything I’ve read is either it’s a seal leak letting air in, fluid contamination, pump is out/going out, or a filter is clogged. There is no manual for this model and I cannot find a filter on it. Any idea where the filter would be? Yes it has the heat exchanger w/12v electric fan. It runs fine for a while but then loses power to where I can’t slew. Any help is appreciated.
There is a strainer/filter in the hydraulic tank. I think you would need to drain the tank and maybe you could put a bore scope in from the filler to see just what it looks like. Could you maybe do that sometime?

Great videos very detailed and informative. I have one question, I can't find the hydraulic oil drain plug on the H12. I have looked in the manual and looked for videos still no success. It doesn't mention or show the location anywhere or how to drain the oil. I feel so dumb. Any help would be appreciated.
I just bought a similar model of excavator and am having tracking issues. It'll go forward and reverse, and can activate each lever individually. But, when I try to turn (levers in opposite directions) it's a no-go. Pressure issue maybe? Thanks.
Great video, thank you! I have a Nuoman MN-12 machine with very jerky controls (mostly boom down and sometimes the travelling motor itself). Is there anything I can change or add to make the movements smoother?
Great video. I do have a question as I just purchased an Erie Industries EM15 which seems just like the Diggit EM15. I was wondering on the round site glass where the fluid level should be? It has a red dot on the center. It didn't have much when purchased and I added sone to the middle but when running it went away from the site glass. Added more and now when stopped it is full on the site glass. Just wondering how you know the correct level and do the rams need to be in a certain position. The tractor repair guyI ask said on an excavator there is fluid on both sides of the rams so it makes no difference but wondering if you could tell me how to get the correct level. Great video and nice to watch a person explain things in detail. Just subscribed and am excited to go back and watch your videos. Thanks for any help you may be able to give me on my question. Stay blessed..
If I was going to add a hydraulic oil cooler which I think is a good idea, it does get really hot in the engine bay, if you live in a location where the ambient temperature is usually above 80° definitely a , if I was going to install one would just get the biggest cheapest metal screw filter for a legacy large machine and Presto you got it oil cooler. Really scratch all that probably too High of pressure for that automatic transmission filter trick but if you need a cool ATF, there’s always that.
Should filter and cooler be added (on return side): a) before going into reservoir (does system has enough pressure to push fluid through filter and cooler??) or b) filter and cooler on the feed-to-pump/suction side after reservoir?? Thanks.
At 5:55 you talk about closed or open center. What you say is not correct. An open center valve sends flow from the pump to the reservoir in the center position, a closed center valve does not, so that dead heads the pump when no function is used. It has not directly something to do with the swing as how you explained. Every control valve can do that, open or closed centre. What you said is what a counterbalance valve is for.
An open center valve would not operate as you said, that would be a tandem center valve. A true open center valve would allow the cylinders to move in the neutral position
i have the same model coming tomorrow, assume i am a complete noob and dont know the difference in hydraulic fluids, but what fluid would you replace the fluid this comes with? i have menards, tractor supply, home depot and walmart locally available.
Hello Sam I have a hydraulic problem motor RPMs run good strong but I bog down at about a 1000 psi I purchased your gauge and increased my pressure to approximately 2300 PSI but when I use my function it still tries to kill the motor h15 model also notice my hydraulic pump seems to get hot very quick, also took out the pressure relief valve and cleaned it did not see anything wrong with it
@@thegarageconnection I read 1/4 on my hoses so I bout some flow restrictors and an adjustable flow valve with NPT 1/4, but found out the fittings are m14, so I’m trying to find some m14 ->npt 1/4 fittings at the moment. Seems like I need a male and female for each restrictor.
Awesome. I recently got one of these machines. I like it but the controls as expected aren't perfect. The Boom/Stick/Bucket controls are slightly touchy but "ok" I've used tractors that are at least as touchy. The slew/rotation is quite touchy and tricky to roll on smoothly but you can with practice. The travel motors are uncontrollably touchy. No matter how soft a touch you have it's so hard to feather movement you pretty much have to give up and use them as on/off which causes some major bucking when trying to move and not entirely safe when trying to get up and down ramps.@@thegarageconnection

@@thegarageconnection yes I am looking into a cooler
Great info on the hydraulics. Mine is so twitchy, do you have any thoughts on how to slow down the hydraulic flow?
I’m actually in the process of getting a flow control valve that will thread right into the cylinder and hose that will be adjustable
@@thegarageconnection will you make a video? That would help others!

I read 1/4 on my hoses so I bout some flow restrictors and an adjustable flow valve with NPT 1/4, but found out the fittings are m14, so I’m trying to find some m14 ->npt 1/4 fittings at the moment. Seems like I need a male and female for each restrictor.
Is there a way to control the flow so the controls aren’t so touchy?
Yes there is. I’m working on a video for this at the moment actually.
Awesome. I recently got one of these machines. I like it but the controls as expected aren't perfect. The Boom/Stick/Bucket controls are slightly touchy but "ok" I've used tractors that are at least as touchy. The slew/rotation is quite touchy and tricky to roll on smoothly but you can with practice. The travel motors are uncontrollably touchy. No matter how soft a touch you have it's so hard to feather movement you pretty much have to give up and use them as on/off which causes some major bucking when trying to move and not entirely safe when trying to get up and down ramps.@@thegarageconnection
