So as an operator and an equipment mechanic i can answer all three of your thumb issues.. it doesnt have the protruding grease nipples because they are prone to getting broken off and allowing dirt into the joints as they are directly in in the path of dirt and rocks from the bucket... the big manufacturers have solved that with moving the zerks to the other side or (more commonly in the pin end rather than the hydraulic cylinder... The pressure bleed of is most likely caused by oil getting past the piston in cylinder to the other side of the piston thus allowing it to relieve pressure on whatever your holding... now that could be the thumb cylinder OR the bucket cylinder doing it. Best to test the bucket bleed off with substantial pressure on it b4 you just rebuild the thumb cylinder. And last but most definitely not least... that bent pin is a manufacturers defect and definitely not caused by you.... a quality pin wouldve held straight and the log wouldve just slipped in the thumbs grip when you hit the tree or whatever it was you hit. Thanks for the most comprehensive series ive seen so far on buying and running one of theese machines.

@johnpike9612 The pin didn't bend it was the "pin bracket" also called a " pin boss" that bent,they are not using a high carbon steel or heat treated steel on this. Metalurgy is an understanding of what types of steel you need to apply to your product! Stock mild steel bends easy,and it's what appears to beuseds here.

There is also a separate pressure relief valve that can be in the pump,or somewhere inline. I'd say the way tgey plumbed the hydraulics,was to save a few bux,instead of using the proper plumbing or valve body at the hydraulic controls. The owner should get a copy of their hydraulic schematics and put a pressure dial on ot (temporary or permanent)that shows how much pressure drops off when he moves it. If they used a hydraulic valve gor a lower pressure, and a smaller gpm pump,you definitely will get a pressure drop. This could be a serious issue in an area full of trenches, etc.

Good review 👍🏼 You are helping a lot of people to find out the real world differences between cheap Chinese copies and more expensive 'name brand' machines. In regards to your hydraulic thumb losing pressure, they can develop internal pressure/fluid leaks, with everything looking fine on the outside. I suspect that is the problem with yours.

Nice review. The thumb circuit relief valve is probably set very very low and won't hold pressure. Follow the thumb circuit back to the valve tree and locate its valve layer. Look on line for how to set the relief valve - generally loosen a jam nut and back out or drive in the relief valve spring screw. You should use a pressure gauge in the thumb circuit to see what the peak pressure is - it is generally set lower than the bucket relief pressure setting - so that the bucket can overdrive the thumb if it needs to and nothing breaks.
Well said . I’m a caterpillar dealer mechanic for 35 yrs and would start with what you suggest. Best case scenario is a relief set too low and only needs adjustment.
These problems are expected for USED items, not newly manufactured items, wtf... sucks for all your problems with this. Such an expensive learning experience, thank you for sharing.
They look super easy to work on compared to cats or Kubotas. Can probly upgrade all the shitty parts as they break whereas I higher end machine cost 3 times as much to repair
Minor issues my man, I'd be quite happy if those were all I had after 50 hours. The great nipples on the thumb are different because standard zerk fittings would get broken off in that location, it's normal practice.
Kind of concerned about the oil you pictured at 0:59 - Mobil does have a Delvac brand hydraulic fluid, but what you pictured is engine oil. Is that what the manufacturer specified?
The thumb fitting is different because what your grabbing would just sheer of any extended grease fitting. What your describing on the hydraulic issues is internal bypassing of fluid. A cab with no A/C would not work well in the south west in the summer time. Very good video. The main question is are you satisfied with the product? You answered that question. Bring up all the flaws helps the manufacturer know how to make the product better, Thanks for the video.
@@einarmikkelsenPNW You like did a quality assurance program on their equipment , they should at least refund your cost. Maybe pay you some extra.. The main question I would have being in Aridzona . It's at least 100 degrees seven months out of the year. Can you get A/C units installed. I wish they they would put a lot more effort in cab design. I want A/C and comfort. A person is going to be sitting in a cab for hours at a time. it really needs to be the best as can be. Climate control is a major issue. I do like the video, and I have a degree in aircraft maintenance , Specializing in fighter aircraft . The new cockpit designs are awesome, and each aircraft newly built normally has better cockpit designs. Temperature control is a top priority. You are correct to point out all the flaws in their product as now they know they could do better, or use better materials.
@@troyb.4101 Thank you! I am a former Airline Transport Pilot, and currently work as a firefighter at an international airport, so I know exactly what you talk about. I wish there was an AC option for my rig. My solution was to remove the door, duct tape the sliding window in the open position, and keep the fan going at all times. I haven't looked into AC, but it would be a game changer. I would first install a fan to exhaust the heat from the engine compartment and add insulation to the fire wall.
@@einarmikkelsenPNW I Will be putting a lot of money into one of these machines soon. I want certain items, and abilities from the machine as I'm 62 years old, and have to maintain my ranch on a very limited income. I only hope some MAJOR improvements are coming soon. It would be better to have the manufacture design every thing for operator comfort. I'm just too old to be cooked all day long!
the lot of these "mechanical" issues could be fixed if they had trained mechanics at their factory. Seems like they might be stretching o-rings to fit. Or just low quality o-rings in general. The thumb losing pressure on squeeze can be fixed if you can find a similar cylinder size and length to install. Or the valve spool allows too much leak by. Only way to know for sure is hook up flow gauges in certain spots to know what is leaking internally where. Im sure there are youtube videos somewhere or online guides if you wanted to know for sure if it was the cylinder or the valve spool. Edit: additionally, if there is a seal kit, you could redo the seals for the cylinder. Also do a visual inspection of the valve body that controls flow to the thumb incase there is no external leaking
@@InevitableTruth247 you can get problems with cavitation and rust using engine oil as water is absorbed by the engine oil while hydraulic oil would not.

It’s normal that you can’t keep pressure on the bucket/thumb. On all excavators it’s similar. It’s because the oil is not compressible and to keep the pressure is a matter of few ml. And with conjonction with the cylinder seals, that are not supposed to be super sealing, because they are heavy duty sealing, they are not rubber but metallic rings, similar than the ones on piston motors. This technology is super durable but it does have a slight leak. The light duty cylinders have rubber seals and can keep pressure a long time. About the tracks and bucket/arm/boom plumbing disorder : it’s not a disorder, it’s a matter of oil sharing in the system and all excavators are similar. But complex excavators does have very complex priorities systems that makes the problem much less obvious. A tracking excavator normally have 2 pumps, one for each track, and from those 2 pumps the other functions are also plumbed. Usually the boom is not plumbed on the same pump than stick so they can move 100% independently. But normally boom is plumbed with bucket so if you want to use both the same time you’ve got to learn how to manage, the one with less pressure will move first !! If you want the pressure to be kept you have to install an accumulator on the pressure side of thumb. Choose one that can withstand the max pressure of your machine. But I think it’s not necessary, for short time holding time the small amount of accumulation provided by the flexible hoses during pressure build is enough.
@ 5.37 when you change direction by curling the bucket. Effectively you starve 1 track motor of oil when you curl the bucket. The digger is built down to a price, and this is 1 area it shows.
My Yanmar B22 will slow down one motor when traveling and trying to lift the boom or another control. But the motors aren’t effected if you operate the blade when traveling, I think a lot of smaller machines make the blade priority when traveling for grading. Most of the time you don’t need to travel and dig at the same time. I’m pretty sure that’s not a “problem” on your machine, it’s more of the functionality of the hydraulic spool valves. Thanks for posting 😊👍
Unpin the thumb rod, install zerk fitting 45* or 90* then turn the rod, grease fitting to the back. Using Diesel engine oil doesn’t sound right for hydraulic oil??
pressure relief valve may be actuated and cause the thumb to lose it's grip. might need it to be set a little higher pressure before the relief pops off.
It could be, but be careful with that. Remember seeing Jesse Muller bending the rod for his thumb, but that was because of NO pressure releif valve. He mentions that you can adjust it. ruclips.net/video/XDNcNV6lPhg/видео.html
You buy cheap you buy 5 times, But I hope you get a good run out of it. I bought a used Yanmar Vio17 with 800 hours on it. Several hundred hours of heavy use later, and zero problems. Kubota and Yanmar every day of the week (in my opinion)
In Australia when you are paying 70 - $80,000 for a 2-3tonne mini excavator and you can get the same size out of Chine for $10 - $25,000 ( cheapest to medium ) get it back in your country, put $5 - 10,000 into it to upgrade most of the running gear, you have your self a pretty good machine for $30,000. For $30K in Australia you would get a small machine with about 6- 8,000 hours on it that looks like they just dragged it out of an old army machine graveyard Fromm WW2
Not sure about the accuracy of your pricing for a new name brand excavator in Australia. I found a new Kobelco 2.7 excavator for sale in NZ for a price of AUD$35000 which includes a GST rate of 15%. I think the new price would be similar in Australia. However in general we do get scalped with highly marked up prices in Australia. Not even mentioning real estate.
Hello there. Accidentally saw your video. About the thumb- that's kinda normal to lose pressure (I own multiple brand new kubotas and caterpillars and all of them lose grip tension on the thumb overtime) .it's the solenoid inside losing pressure most likely. About that brush strip I can give you part number from my caterpillar one(which visually looks very similar only longer).I recently bought one at cat and it's 3 ft long with super sticky tape in the back. Paid $6 or 7. How much this machine cost you if not secret?
You can put in a grease zirc for that thumb that will match the others. Can likely get at Tractor Supply - or that type of store. The thumb hydraulic creep on the thumb is likely leakage inside the hydraulic control valve...that can be difficult to fix.
Thank you. I think I will keep the fitting that is there now, as many people say that I would break off a zirc fitting. It is flush for a reason. Makes sense.
all i find strange about the thumb grease zerks is...why not drill the pin and recess it in there? like all the other pins? "options that i got". its the afterthought sitting on the shelf over there, and we throw it on the orders that asked for it... if we remember to... the hot firewall may be nice in winter. may want a decent auto fan stuck under there for summer? may find its more about heat flow management rather than any insulation... badly placed oil cooler, and yeah... its pretty tight in there...
😂😂 hydraulic thumb "....it slowly releases presure...." *walks under boom*. Interesting review series, often wondered at just how bad the cheap offshore stuff is, and if it's possible to do like you are, and just go through it as stuff breaks and falls off to sort it out.... but looking at that thumb... You are a braver man than me.
@@einarmikkelsenPNW yeah I get that... but if it releases, it releases. Just be careful bud. Dont put yourself between a machine and something that is less squidgy than you. Be it the ground, a wall or another machine.
Sounds like the thumb is bypassing internally. The seals on the piston are likely not properly installed, since it's new they are likely installed wrong or damaged. You can try and tear it down and replace the seals yourself or take it to a hydraulic shop and get the pros to do it. Some of these seals can be a real pain so they will likely make you bleed, be warned. I bet the hydraulic motor doesn't have enough juice for both tracks and whatever else you try and do at the same time. I think that's something you'll likely have to keep in mind. You'll have to switch out those fitting on your own bud. I bet the thumb isn't even made in the same factory lol. I'm also willing to bet there is HOT HOT engine components behind that back wall and that is why it gets so hot in the cab from it. You could try looking in the engine compartment to see what is in there and attach a fan to blow across the engine compartment.
@@einarmikkelsenPNW Or have a separate plate to take the radiant heat. Just like under cars they have this barrier of standing air between 2 plates between exhaust and the body of the car. If there is room for it, but that is a diy and a half :)
the cylinder for the thumb probably needs a better seal on the inside. if you pull it apart you can usually just measure the old one and find a replacement. You already can see the seals on this machine are junk as you replaced multiple already LOL
It's normal for the travel motors to slow down and cause you to veer right or left if you use the bucket or some other function while moving. ,y takeuchi Wil do that. It's a symptom of some ofmthe hydraulic flow being robbed from the travel function to do another task. My machine has 2 pumps, one works the right track, boom, swing.....the other works left track, blade, bucket etc. So the right side will slow down if I swing the machine while moving since that side pump is running 2 functions while the other side is simply travelling
The hydraulic issue why you got to keep putting pressure on every so often is because the hydraulic is leaking back inside the hydraulic cylinder the seal is not holding pressure and allowing the hydraulic to leak back
@@calspaugh8078 I know that the can in the video is engine oil. I picked up the wrong one for the video. They look similar, but the hydraulic fluid used is regular hydraulic fluid.
Don't feel bad about your thumb. Mine was brand new from cat, and it loses pressure over a while. Not really an issue since I just use it to pickup trees and toss them.
Also about your zerk fittings, rotate the ram to the other side and replace the zerk with a standard size. If you leave it in that spot, it'll probably snap off picking up logs 🤣
Actually, I don’t think that’s true at all. A great thing with the Chinese machines is that the spares and accessories are much cheaper, and a lot of the mechanical equipment…engines and pumps are mainstream, proprietary makes anyway.
Grease fitting on the thumb maybe be like that so it doesnt get messed up when grabbing material. Also your cylinder maybe leaking pass the seals on the end of the rod. Wouldn't be surprised if the cut one while assembling it.
Wanted to say the same about the cylinder seals. When you are 100% sure that there are no leaks anywhere, then it's most likely, bc I don't think that even chinese mess up the valve block. Possible, but since you already had one damaged seal from the factory assembly, it doesn't take much to make a little nick into the pressure seal when installing the cylinder rod. It shouldn't be an expencive fix when you can get it open by yourself, but it is quite messy and have to top off hydraulic fluid after (again).
I sold Terex mining equipment for 3 years and Case equipment for 26 years. One important thing to remember when buying construction equipment, good equipment is not cheap and cheap equipment is not good!
Those two grease fitting are in an area that would possibly be compromised when using the thumb.... I know, they thought this through but missed so many others.....bummer
So how much was shippìng from china to what state in u.s.? Or was it free shipping? Do they charge extra for attachments and how much? I am looking at buying some with attach.ents.😮
I have a 1ton hightop ht10b. Paid 11,500 after taxes. If i had bought in Kubota in the same size would cost 22,000. So if you buy cheaper unit you will have to fix some thing. As far as the thum blending off. It may be cylinder in side.
Thumb issue could be a few things, bad relief valve for close function, cylinder seals bypassing. The travel issue or it turns when multi function operation is lack of pump oil for all functions so the travel circuit is the one that suffers the most. Better machines with slightly more complex hyd systems ensure travel circuit is priority and it’s the other functions that suffer the loss of speed. Hard to say otherwise without hooking some gauges up to it and seeing what’s going on.
Moving and using boom or stick... there is two hydraulic pumps, when tracking each motor uses a pump each, boom and stick use pump each, so when tracking/ moving then use any other hydraulics your taking power from motor using same pump.
You are loosing griping power on the thumb is because the seal for the hidraulic piston is worn out. Thats one of the causes i wod start there(rebuild kit for the hidraulic cylinder.
i would check up with your walmart or the person who recommended the 15w-40 engine oil as hydraulic oil cause my guess would be that that stuff is way to thick to run properly seeing regular hydraulic oil is alot less viscose than 15w-40 which is normally a engine oil for engines with some wear or big diesels hell it even says it on the can you showed "heavy duty diesel engine oil" which is a very different application than hydraulics
as far as you comments related to the tracking while doing another function. - the problem is will all excavators. my CAT304 does this worse then any other. This is due to the mashine having limited ways it can use its 1-2 hydraulic pumps. the same pump that controlls your tracks is shared with something else so you can't spin them in different directions at the same time. also with the thumb bleading off. this is likely a problem with the cylinder it self. the packing/seals on the end of the piston rod (also known as the pistion seal) is bypassing slowly. this problem will get worse over time. i would recomend handling it before it gets worse as damaged seals can cause contact with the rod seals and the inner bore of the cylinder wall making what is likly a sub 50$ fix a 500-1000$ one.
As a factory in China specializing in the production of excavators, we do not manufacture excavators of such poor quality. Hence, our excavators are priced much higher than those of other factories.
15W40 Engine oil is used by many, many heavy equipment dealers in all types of equipment. As to the high temperatures behind the operator's seat, personally I would concern myself with that issue before the others as the manufacturer put a larger engine in your machine and I can only assume it's Not being cooled or vented properly or good enough. Buy a cheap laser temperature tool and see how hot the engine compartment is, the heat is not good for the machine and could even be causing hydraulic oil issues on the machine! I'll also guess the hydraulic fluid cooler is way too small and possibly not vented properly leading to even more issues down the road. I suggest a trained heavy equipment dealer looks it over as they know best, most times! 😊
You will find that while tracking and move the boom at same time it will affect the direction of travel I find it’s more of a problem with smaller machines the thumb might be losing pressure internally in the ram good luck with it personally I would never buy anything but a Kubota
If you change greasing nipples on the thumb to regular ones, it will for sure break at some point, cause it is pointing out and will catch on someting...
Other nipples are not in the area which is in direct contact with materials that will be handled or are in enclosed area, which prevents most of the possible cases where they can break...
How much did you pay after shipping, tax, etc. If i may ask? I may be interested in purchasing one also.

Nice review. The thumb circuit relief valve is probably set very very low and won't hold pressure. Follow the thumb circuit back to the valve tree and locate its valve layer. Look on line for how to set the relief valve - generally loosen a jam nut and back out or drive in the relief valve spring screw. You should use a pressure gauge in the thumb circuit to see what the peak pressure is - it is generally set lower than the bucket relief pressure setting - so that the bucket can overdrive the thumb if it needs to and nothing breaks.
Thanks! I'll give it a try
Well said . I’m a caterpillar dealer mechanic for 35 yrs and would start with what you suggest. Best case scenario is a relief set too low and only needs adjustment.
Great honest review...well done fella and thank you .
These problems are expected for USED items, not newly manufactured items, wtf... sucks for all your problems with this. Such an expensive learning experience, thank you for sharing.
You got it, my man. Merry Christmas 🎄🎁 I have about 170 hours on it now and no big issues. Just annoying minors that are fixed.
I think you have a good buy, many of the big name machines have lots of problems too, but are a lot more costly to fix.
I think you are right.
They look super easy to work on compared to cats or Kubotas. Can probly upgrade all the shitty parts as they break whereas I higher end machine cost 3 times as much to repair
Minor issues my man, I'd be quite happy if those were all I had after 50 hours.
The great nipples on the thumb are different because standard zerk fittings would get broken off in that location, it's normal practice.
Thanks. Yes, all minor issues. I love the machine.
Thank you for your review Einar!
My pleasure!
Kind of concerned about the oil you pictured at 0:59 - Mobil does have a Delvac brand hydraulic fluid, but what you pictured is engine oil. Is that what the manufacturer specified?
Glad I wasn’t the only one who saw lol😂
Scrolled so long to find first comment about engine oil vs hydraulic oil
I accidentally showed the wrong container
The thumb fitting is different because what your grabbing would just sheer of any extended grease fitting. What your describing on the hydraulic issues is internal bypassing of fluid. A cab with no A/C would not work well in the south west in the summer time. Very good video. The main question is are you satisfied with the product? You answered that question. Bring up all the flaws helps the manufacturer know how to make the product better, Thanks for the video.
Got it. Thanks 😊
@@einarmikkelsenPNW You like did a quality assurance program on their equipment , they should at least refund your cost. Maybe pay you some extra.. The main question I would have being in Aridzona . It's at least 100 degrees seven months out of the year. Can you get A/C units installed. I wish they they would put a lot more effort in cab design. I want A/C and comfort. A person is going to be sitting in a cab for hours at a time. it really needs to be the best as can be. Climate control is a major issue. I do like the video, and I have a degree in aircraft maintenance , Specializing in fighter aircraft . The new cockpit designs are awesome, and each aircraft newly built normally has better cockpit designs. Temperature control is a top priority. You are correct to point out all the flaws in their product as now they know they could do better, or use better materials.
@@troyb.4101 Thank you! I am a former Airline Transport Pilot, and currently work as a firefighter at an international airport, so I know exactly what you talk about. I wish there was an AC option for my rig. My solution was to remove the door, duct tape the sliding window in the open position, and keep the fan going at all times. I haven't looked into AC, but it would be a game changer. I would first install a fan to exhaust the heat from the engine compartment and add insulation to the fire wall.
@@einarmikkelsenPNW I Will be putting a lot of money into one of these machines soon. I want certain items, and abilities from the machine as I'm 62 years old, and have to maintain my ranch on a very limited income. I only hope some MAJOR improvements are coming soon. It would be better to have the manufacture design every thing for operator comfort. I'm just too old to be cooked all day long!
@@troyb.4101 Unless you plan on working in the rain, don't buy an enclosed cab. They block the view, cost more money, and get very hot.
so if you do not get the enclosed cab many of these problems will disappear.
The majority!
the lot of these "mechanical" issues could be fixed if they had trained mechanics at their factory. Seems like they might be stretching o-rings to fit. Or just low quality o-rings in general. The thumb losing pressure on squeeze can be fixed if you can find a similar cylinder size and length to install. Or the valve spool allows too much leak by.
Only way to know for sure is hook up flow gauges in certain spots to know what is leaking internally where. Im sure there are youtube videos somewhere or online guides if you wanted to know for sure if it was the cylinder or the valve spool.
Edit: additionally, if there is a seal kit, you could redo the seals for the cylinder. Also do a visual inspection of the valve body that controls flow to the thumb incase there is no external leaking
Thank you very much for all the great info. I'll be checking it out.

wish you all the best
greetings from Slovenia EU
Hey im so glad to have seen all the extras they make you pay its rediculouse no one lifts a finger for nothing even the ones who just find someone else to lift their fingers gets their hand in the pot lol
Im not shure if its this way everywhere but bet prob is unfortunately ty for this vid have alot to think about now lol😂
Did you keep the receipt?
In hand
It’s normal that you can’t keep pressure on the bucket/thumb. On all excavators it’s similar. It’s because the oil is not compressible and to keep the pressure is a matter of few ml. And with conjonction with the cylinder seals, that are not supposed to be super sealing, because they are heavy duty sealing, they are not rubber but metallic rings, similar than the ones on piston motors. This technology is super durable but it does have a slight leak. The light duty cylinders have rubber seals and can keep pressure a long time.
About the tracks and bucket/arm/boom plumbing disorder : it’s not a disorder, it’s a matter of oil sharing in the system and all excavators are similar. But complex excavators does have very complex priorities systems that makes the problem much less obvious. A tracking excavator normally have 2 pumps, one for each track, and from those 2 pumps the other functions are also plumbed. Usually the boom is not plumbed on the same pump than stick so they can move 100% independently. But normally boom is plumbed with bucket so if you want to use both the same time you’ve got to learn how to manage, the one with less pressure will move first !!
If you want the pressure to be kept you have to install an accumulator on the pressure side of thumb. Choose one that can withstand the max pressure of your machine. But I think it’s not necessary, for short time holding time the small amount of accumulation provided by the flexible hoses during pressure build is enough.
Thanks
@ 5.37 when you change direction by curling the bucket. Effectively you starve 1 track motor of oil when you curl the bucket. The digger is built down to a price, and this is 1 area it shows.
That makes sense
My Yanmar B22 will slow down one motor when traveling and trying to lift the boom or another control.
But the motors aren’t effected if you operate the blade when traveling, I think a lot of smaller machines make the blade priority when traveling for grading. Most of the time you don’t need to travel and dig at the same time. I’m pretty sure that’s not a “problem” on your machine, it’s more of the functionality of the hydraulic spool valves. Thanks for posting 😊👍
@Mikefestiva I appreciate your insight and feedback.
Do theses implement work on other mini
Yes. It is a standard size
do you have a video with the excavator in action?
I am going to put together one shortly. I have to dig a sewer line.
The grease fittings can be swapped easily, Unbolt them and bolt in the correct fitting.
Thanks
They are that way for a reason. That is a high material handling area and will plug up or break off
great details, love this video
Thank you!
Unpin the thumb rod, install zerk fitting 45* or 90* then turn the rod, grease fitting to the back.
Using Diesel engine oil doesn’t sound right for hydraulic oil??
Correct about the oil. I showed the wrong container by accident.
Is it still working ? 😅
Yeah, man. There are a few follow-up videos you can watch. I love it.
The low pro fittings on thumb are a must... I’m surprised they even put them on there. Standards ones will be broke off in no time
Thanks. That is what I have since learned.
I happened to notice that the hydraulic fluid you showed is actually 15w 40 motor oil.
This is what they recommend?
And in the winter???
if you have any excavator requirements,you can contact me. i will help you,i am a factory of excavator and forklift
pressure relief valve may be actuated and cause the thumb to lose it's grip. might need it to be set a little higher pressure before the relief pops off.
It could be, but be careful with that. Remember seeing Jesse Muller bending the rod for his thumb, but that was because of NO pressure releif valve. He mentions that you can adjust it. ruclips.net/video/XDNcNV6lPhg/видео.html
@@djdeaf13 remember the "quality control"
For sure be careful with adjusting that valve, use a gauge to adjust it.
Thank you
Thank you
Good call.
Changing grease fittings is an extremely easy job to do yourself
Absolutely
Not as easy as breaking it off will be if it’s changed to the style that sticks out.
You buy cheap you buy 5 times, But I hope you get a good run out of it. I bought a used Yanmar Vio17 with 800 hours on it. Several hundred hours of heavy use later, and zero problems. Kubota and Yanmar every day of the week (in my opinion)
At least mine has a Yanmar engine 👏
The grease fittings are different for range of motion. The thumb would crush the fitting during operation
That makes sense.
@nathangregory9002 is that how he acts?
Got it
In Australia when you are paying 70 - $80,000 for a 2-3tonne mini excavator and you can get the same size out of Chine for $10 - $25,000 ( cheapest to medium ) get it back in your country, put $5 - 10,000 into it to upgrade most of the running gear, you have your self a pretty good machine for $30,000. For $30K in Australia you would get a small machine with about 6- 8,000 hours on it that looks like they just dragged it out of an old army machine graveyard Fromm WW2
I am very happy with my excavator so far. I like the idea of putting money into upgrades
Not sure about the accuracy of your pricing for a new name brand excavator in Australia. I found a new Kobelco 2.7 excavator for sale in NZ for a price of AUD$35000 which includes a GST rate of 15%. I think the new price would be similar in Australia. However in general we do get scalped with highly marked up prices in Australia. Not even mentioning real estate.

Hello there. Accidentally saw your video. About the thumb- that's kinda normal to lose pressure (I own multiple brand new kubotas and caterpillars and all of them lose grip tension on the thumb overtime) .it's the solenoid inside losing pressure most likely.
About that brush strip I can give you part number from my caterpillar one(which visually looks very similar only longer).I recently bought one at cat and it's 3 ft long with super sticky tape in the back. Paid $6 or 7.
How much this machine cost you if not secret?
I have an entire video about the order price and import charges. I think it was about $25k total
Please keep accidentally watching my videos :)
The travel issue is probably because the pump can not supply enough fluid to do multiple actions at once.
Thanks
Do u have trouble keeping tracks on? I have nt45 which is 2.5 ton with 9 inch wide tracks. Yachoo tracks. Track about 6.5 ft long.
No. No issue at all.
Do these Chinese mini excavators have good manuals to help you with repairs, finding compatible spare parts?
Absolutely. I have found everything locally.
engine oil as hydro fluid??
Haha. I accidentally showed the wrong container
You can put in a grease zirc for that thumb that will match the others. Can likely get at Tractor Supply - or that type of store.
The thumb hydraulic creep on the thumb is likely leakage inside the hydraulic control valve...that can be difficult to fix.
Thank you. I think I will keep the fitting that is there now, as many people say that I would break off a zirc fitting. It is flush for a reason. Makes sense.
all i find strange about the thumb grease zerks is...why not drill the pin and recess it in there? like all the other pins?
"options that i got".
its the afterthought sitting on the shelf over there, and we throw it on the orders that asked for it... if we remember to...
the hot firewall may be nice in winter. may want a decent auto fan stuck under there for summer? may find its more about heat flow management rather than any insulation... badly placed oil cooler, and yeah... its pretty tight in there...
I'll look into getting an auto fan.
The thumb is bleeding off internally on a valve, and you are correct the hydraulic system isn’t strong enough to do multiple things

Yes, the thumb is bypassing on a valve and the tracking issue might be related to valving also.

The thumb probably releases slowly because of air in the hydraulic lines.
Thanks
Bypassing
I checked the price of hydraulic oil in China and found that 16L is priced between $18 and $32 based on different grades
Thanks
Sounds like the thumb is bypassing internally. The seals on the piston are likely not properly installed, since it's new they are likely installed wrong or damaged. You can try and tear it down and replace the seals yourself or take it to a hydraulic shop and get the pros to do it. Some of these seals can be a real pain so they will likely make you bleed, be warned.
I bet the hydraulic motor doesn't have enough juice for both tracks and whatever else you try and do at the same time. I think that's something you'll likely have to keep in mind.
You'll have to switch out those fitting on your own bud. I bet the thumb isn't even made in the same factory lol.
I'm also willing to bet there is HOT HOT engine components behind that back wall and that is why it gets so hot in the cab from it. You could try looking in the engine compartment to see what is in there and attach a fan to blow across the engine compartment.
Thanks!
@@einarmikkelsenPNW Or have a separate plate to take the radiant heat. Just like under cars they have this barrier of standing air between 2 plates between exhaust and the body of the car. If there is room for it, but that is a diy and a half :)
the cylinder for the thumb probably needs a better seal on the inside. if you pull it apart you can usually just measure the old one and find a replacement. You already can see the seals on this machine are junk as you replaced multiple already LOL
I will do that. Thanks!
how much was it all in out the door price in usa dollars thanks
I have another video where I break down all the prices. Check it out
The thumb doesn’t have a zerk fitting because it would get broken off by debris where they are located.
That makes sense. Thanks.
“Should have been done during quality control at the factory”… 😂😂😂
How loud is your digger? My brother bought 1 and with a diesel single cylinder engine it is LOUD. There is also no room to upgade the exhaust, either.
It isn't very loud. It has a Yanmar engine
Really not bad
Id get that thumb checked
Sounds like another o ring on your thumb is leaking back
Check your cylinder o ring
I think you are right
It's normal for the travel motors to slow down and cause you to veer right or left if you use the bucket or some other function while moving. ,y takeuchi Wil do that. It's a symptom of some ofmthe hydraulic flow being robbed from the travel function to do another task.
My machine has 2 pumps, one works the right track, boom, swing.....the other works left track, blade, bucket etc. So the right side will slow down if I swing the machine while moving since that side pump is running 2 functions while the other side is simply travelling
Now I know. Thanks
exactly, i own the smalles yanmar mini(0,8T) and it also has only 1 pump, same "problem" while moving the machine.
@@B100-c4m It is a bit annoying, but for the price, I can deal with it.
My New Holland doesn't.
So, pretty typical for a Chinese assembly. The thumb losing pressure is a major disappointment. Could be a leaky piston seal inside of the ram?
It could be. I haven't opened it up yet.
The hydraulic issue why you got to keep putting pressure on every so often is because the hydraulic is leaking back inside the hydraulic cylinder the seal is not holding pressure and allowing the hydraulic to leak back
Thank you. Another bad o-ring...
ENGINE OIL in the hydraulics!!!!!! ( 1:00 min in )
Yea that’s not hydraulic oil dude. There’s your problem
@@calspaugh8078 I know that the can in the video is engine oil. I picked up the wrong one for the video. They look similar, but the hydraulic fluid used is regular hydraulic fluid.
Does it overheat overall? Can you run it continuously for couple hours?
It never overheats. I have run it for 5 hrs continuously
Don't feel bad about your thumb. Mine was brand new from cat, and it loses pressure over a while. Not really an issue since I just use it to pickup trees and toss them.
Also about your zerk fittings, rotate the ram to the other side and replace the zerk with a standard size. If you leave it in that spot, it'll probably snap off picking up logs 🤣
Same here. I don't know if I will take mine apart. It works too well.
That is a very good point

Thumb maybe passes by the the orientation valve (not sure how you call it)
True.
the thumb ram is i 5:52 n your hydraulic vave

Grease fitting on the thumb maybe be like that so it doesnt get messed up when grabbing material.
Also your cylinder maybe leaking pass the seals on the end of the rod. Wouldn't be surprised if the cut one while assembling it.
Wanted to say the same about the cylinder seals. When you are 100% sure that there are no leaks anywhere, then it's most likely, bc I don't think that even chinese mess up the valve block. Possible, but since you already had one damaged seal from the factory assembly, it doesn't take much to make a little nick into the pressure seal when installing the cylinder rod. It shouldn't be an expencive fix when you can get it open by yourself, but it is quite messy and have to top off hydraulic fluid after (again).
Thanks

@@jtsokiehobbyandadventures6666 @einarmikkelsenPNW did. he showes the oil he is using and it motor oil.
@chrishanson9542 sorry didn't pay attention to that. But you are righr
Thumb issue could be a few things, bad relief valve for close function, cylinder seals bypassing. The travel issue or it turns when multi function operation is lack of pump oil for all functions so the travel circuit is the one that suffers the most. Better machines with slightly more complex hyd systems ensure travel circuit is priority and it’s the other functions that suffer the loss of speed. Hard to say otherwise without hooking some gauges up to it and seeing what’s going on.
Thanks
At 37 seconds in looking at track drive, was that a snake???🐍
Hahaha 😂 No, that was the track moving in the background.
Moving and using boom or stick... there is two hydraulic pumps, when tracking each motor uses a pump each, boom and stick use pump each, so when tracking/ moving then use any other hydraulics your taking power from motor using same pump.
Thanks
Your thumb is bypassing hydraulic oil in the cylinder of at the control valve.

You are loosing griping power on the thumb is because the seal for the hidraulic piston is worn out. Thats one of the causes i wod start there(rebuild kit for the hidraulic cylinder.
Thanks!
@@einarmikkelsenPNW i would do a full rebuild not just the piston
i would check up with your walmart or the person who recommended the 15w-40 engine oil as hydraulic oil cause my guess would be that that stuff is way to thick to run properly seeing regular hydraulic oil is alot less viscose than 15w-40 which is normally a engine oil for engines with some wear or big diesels hell it even says it on the can you showed "heavy duty diesel engine oil" which is a very different application than hydraulics
So sorry. I showed the wrong container. It is so similar to the hydraulic fluid container.
Thank you for making this, not sure why you would recommend it though. I got the impression that Chinese build things like they build their buildings…
All these issues are very minor. If you look over the comments on this video, people are having the same issues on all name brand units as well.
as far as you comments related to the tracking while doing another function. - the problem is will all excavators. my CAT304 does this worse then any other. This is due to the mashine having limited ways it can use its 1-2 hydraulic pumps. the same pump that controlls your tracks is shared with something else so you can't spin them in different directions at the same time.
also with the thumb bleading off. this is likely a problem with the cylinder it self. the packing/seals on the end of the piston rod (also known as the pistion seal) is bypassing slowly. this problem will get worse over time. i would recomend handling it before it gets worse as damaged seals can cause contact with the rod seals and the inner bore of the cylinder wall making what is likly a sub 50$ fix a 500-1000$ one.
Thanks!
As a factory in China specializing in the production of excavators, we do not manufacture excavators of such poor quality. Hence, our excavators are priced much higher than those of other factories.
That makes sense. You get what you pay for.
how much for a 2.6T
15W40 Engine oil is used by many, many heavy equipment dealers in all types of equipment. As to the high temperatures behind the operator's seat, personally I would concern myself with that issue before the others as the manufacturer put a larger engine in your machine and I can only assume it's Not being cooled or vented properly or good enough. Buy a cheap laser temperature tool and see how hot the engine compartment is, the heat is not good for the machine and could even be causing hydraulic oil issues on the machine! I'll also guess the hydraulic fluid cooler is way too small and possibly not vented properly leading to even more issues down the road. I suggest a trained heavy equipment dealer looks it over as they know best, most times! 😊
Thank you. I accidentally showed the wrong hydraulic fluid in the video.
im going to buy one in the philippines .....but im thinking of buying used...thank you for the video....the only Chinese brand I like is xcmg
Good choice!
How much dis you pay for it ?
I think it was about 25,000 after the import taxes. I made an entire video with a breakdown of all the fees.
You will find that while tracking and move the boom at same time it will affect the direction of travel I find it’s more of a problem with smaller machines the thumb might be losing pressure internally in the ram good luck with it personally I would never buy anything but a Kubota
Thanks
The thumb cylinder may be leaking internally
I think you are right.
If you change greasing nipples on the thumb to regular ones, it will for sure break at some point, cause it is pointing out and will catch on someting...
Okay, but that isn't an issue on any of the other ones?
Other nipples are not in the area which is in direct contact with materials that will be handled or are in enclosed area, which prevents most of the possible cases where they can break...
