The reason that hydraulic thumbs give out against the digging cylinder is so that thumbs cylinder doesn’t get bent. Should be able to adjust the relief pressure so it doesn’t give out as easulu
Correct.. Any machine with a thumb has a pressure regulator set lower than the bucket cylinder pressure. He can turn it up like he wants but then stuff will probably break
I have never worked on trackhoes but I did do hydraulic work for a number of years. Hydraulic oil is not compressible and is actually stronger than steel under compression loading. If the thumb cylinder is moving under a load then you have oil "bypassing" some where. Either in the piston chevrons or the valve body or a relieve valve setting is to low. Good luck on working out this problem.
@elem arha Sir, I do not know if the valve that operates the thumb cylinder is an "open center" or a "closed center" valve but I do know this for a fact, if the valve is a "closed center" valve then both lines are blocked off when the valve is in the neutral position. That means that no oil can move through the lines, in either direction. That means that the oil in the thumb cylinder is NOT exposed to any "relief valve". On an open center valve system it would still only be exposed to a relief valve during the moving event. It is a safety feature that is required on all hydraulic systems to prevent devices from "lowering" by accident under a heavy load.
@@davidtyndall9604 open center or closed center only has to do with de pump system. Pressure return to tank or non return. Most of the valves that are used with small and mid sized excavators are build with closed a and b ports with pressure reliefs n the cilinder ports a&b
im 46 years old and this young man here is teaching me new thing in each videos, he will raise my skill level , this is my kind of learning , not sitting in school but listening to someone who actually is doing the job and has the technical know how to explain how to do it, cheers Andrew
I laughed when Andrew paced out that log in seconds, Wranglerstar would still be talking about his genuine North Western loggers tape, artistically videoing himself nailing the end in, and then giving us a 15 minute story about the time his Father wrestled a bear during a blizzard back in '62...
@Steve Diamond I dunno. Tried to watch his videos about 4 years ago... Couldn't even finish the first one lol IMO It's not comparable to Andrew's channel which is a real channel and not a bunch clickbait and pointless talking but I guess that's what RUclips likes.. Andrew deserves 1 million subs way more than Wranglerstar.
Love your channel! I’m a diesel tech and I’m trying to get into the trucking and excavation end of it, as well as continuing repairs for others. You’re an inspiration! Thank you!
I've been on RUclips since 2006. You are the first channel in about 5 years I have consistently watched every single video you put out, and are one of the only that I actively go back and watch old videos like a TV show. Please don't stop what you do. Your film and commentary work has really improved over time. I'm just stunned on how good these videos are...
Definitive tutorial on excavator thumbs! So many useful/important points made in this segment; invaluable. Astonishing to see what even a tiny excavator can lift and move around; this wasn’t just great on thumbs but an ad for excavators. Thanks Andrew.
That was nice seeing the whole fleet of excavators all at once, and how you made Levi's foot print. Like others said the pressure is altered on the thumb spool to be lower. There is a video of a guy putting a new hyd thumb on a JCB 212 that had a double acting pedal, but it was set up to run a hammer with a free return and one feed. The kit fitting instructions told him how to plumb in the extra line and set the spool relief pressures so the thumb moved with the bucket like your Kubota does. There is a thumb kit available now for the extender style like the Deere has. JCB use the same system, the thumb bracket mounts to the bottom of the extending boom. It then has a dog leg crank in the bracket that steps out over the fixed part of the dipper stick with the rest of linkage on. The rest of the cranked out bit's not fixed to the stationary part, so the extender still slides out and the grapple goes with it. Yes a backhoe thumb's not quite so nice but it sure beats picking awkward crap up by hand and loading it in a truck L.O.L. Thanks for the video, take care .
Have you ever considered that it might not be Andrew they’re not giving him personally a thumb’s down, but rather the subject matter of the video? I, for one, don’t care for the snowmobile videos. I get the feeling he posts some of those just to be posting something. Nor am I crazy about the jet skis or wave riders, though I do have to admire his courage for practically swimming in the Hudson. God knows what’s in that water. For instance, I like Samuel L. Jackson, but I don’t have to like every movie he makes. I’m not attacking Jackson, just the movie. I would say I’ve given a thumbs up to 99% of his videos, but there is that odd one which just doesn’t grab me. This video is one of his very best. It’s a rather brilliant essay on the importance of having a thumb on the excavator, and I got much out of it. And those very rare occasion where I don’t care for the video, rest assured that the fault lies in the subject matter, not with Andrew.
Dogs front legs are designed to be used to dig a den from a hill side so their front legs move like an excavator in the digging position. Their rear legs push the dirt aside that the front legs have pulled out.
Andrew....thanks so much for doing this video. You really are a natural teacher/instructor. You don't even need notes. You just know what the hell you're doing. That's a gift, believe me.. I taught college for years. Many people know what they're doing, but can't explain it to other people. You're blessed with the ability to do both: know how to do something, and also have the ability to explain what he doing to someone else.
Levi for President is bound to be a far more productive presidency with way fewer people going to prison on his behalf. Put some common sense back into politics, vote Levi for President.
The hyd thumb curls in with the bucket.... that's normal. The relief valve for thumb is set lower than relief for bucket. If they are set the same, you would bend/break hyd cylinders. Normal operation for a hyd thumb.
Why do people dislike Andrews Videos he makes them on his own time and goes through editing and filming and doing all the work to HELP you guys no reason to dislike but you do you
For our work doing land clearing and logging road, a mechanical thumb was better than no thumb, but after going hydraulic in 1990 we never looked back. Good video! 👍
Reason for weaker hydraulic thumb force pushing against the bucket: to keep from smashing the fork. The bucket has a tremendous amount of push; if the thumb cylinder was equally strong, the forks would have to be built as strong as the bucket.
I haven't seen anyone that is anywhere near as entertaining as you Andrew. And a large part of that is due to your proficiency using your equipment. No wasted effort. Others seem to take twice as long and the results are less than pleasing. Your jobs always turn out nice.
I love your videos Andy. I work in the UK as a Civil Engineering Professional and have no trade experience hands on with the machinery and tools used on the day to day so I really learn a lot from your videos. You're also really keen and I appreciate that!
Andrew thanks to your wonderful videos I can now thrill my wife with a full explanation of the value of a thumb. We saw an excavator with a hydronic thumb so for the next ten miles I was able to dazzle her with your knowledge. She was so thrilled
Andrew Camarata, my new reality TV show. I never know when there is a new episode.....just when it comes out I HAVE to watch it!!! Solid work man!!!! Don't ever stop!!!!
I think this is your most polished video yet! The sound was great! It was great to hear your thoughts as you were demonstrating the machines, as opposed to a voiceover (not that theres anything wrong with that either). Love Levis personalised stamp too :) Also drone skills at the end there! Entertaining and informative as usual. Thanks :)
Well he's probably making more from you tube now, then he is actually excavating jobs has to keep this train rolling. But he will because its freaking Andrew.
I have never operated heavy equipment nor have I worked in any field related to it and yet I was able to name the make and model of every one of your excavators (except the backhoe) Thanks for the free education, Andrew!
Next video: it’s time to sell the backhoe! Thanks for taking the time to inform us on pros and cons for the thumb attachment! Very informative, keep teaching will keep watching!
I have a backhoe with no thumb, but I want one sooo badly. That being said, learning how to scoop and move things without a thumb when you are first starting out teaches some good lessons!
Andrew your collection of excavators reminds me of my boot collection. Both were accumulated over years. Each one served its purpose as desired. Every one was chosen because I could afford it at the time and it fit just right. I kept the ones I did because, with the right care, they have lasted forever. I keep all my collection in one closet. You must have a pretty big closet for yours. Thanks for the video.
You are Awesome Andrew, another great how to video, such an entertaining teacher! This is by far my favorite channel, I love everything about you and I’m proud to say it!
Wouldn’t I be able to just use the lines off the swing boom, and control thumb w the floor controls? I’m not sure, but I think I’d also have to get new joystick w other function control if I went w diverter. So confusing lol. Hey I have a great idea, I’m from colebrook ct not to far from you. I’ll bring up machine and you can make great video of you installing thumb on my b27. Lol. Been watching your videos from the beginning. Always look forward to your material. Thanks commenting back.
My 4 year old grandson watches you daily and as a pro operator for 30 years I enjoy watching you. I never have used a non hydraulic thumb, but I'm considering putting one on my yanmar vio70 because of the cost of putting a hydraulic on. One thing I will say with love you are definitely hard and stuff and it's good that you own your equipment owners don't like using the counterweights as battering rams lol
Best of your videos so far. My 4 yo son is addicted to watching your digging. Instead of asking me to play him kids movies he's asking me to play your digging videos several times a day.
Hello Andrew Camarata, About two months ago I started watching RUclips, I found Your Andrew Camarata doing excavating. I used to do excavation for septic systems, driveways and land clearing for a private contractor. He had an HD-21 Bulldozer a midsize Excavator, Diamond Rio Tractor and trailer, D-8 Cat Bulldozer. I operating most them quite often. I started watching and I became hooked on your RUclips. This is my first time writing a comment about the videos that you created. I am impressed with you knowledge of making videos. I have watched everyone that you have made and looking forward to more from you. Rev. Ronald N. Allen
That's an innovative way of paying for new tracks for the Excavator! 25 track pads at $50 each, minus shipping is a good chunk of the cost of 2 tracks!
From an old Vocational Teacher. This may be the best video you have ever made. GREAT examples of thumbs; WONDERFUL progression of the thumbs with advantages and short Cummings of the samples, Quality reviews and recommendations! An option I have just come up with on plumbing thumbs, “I'm doing this on my current thumb build” evolves plumbing the thumb into the bucket curl cylinder hydraulics. Plum the top hoses into each other, plum the bottom hoses into each other. Then put a electronic hydraulic valve inline of the top hoses. Install a electric momentary switch onto one of your hand controls. When you want the thumb to move, press the switch; both the bucket and the thumb will open or close with the switch activated, let go of the switch and the thumb will stay at this position. Again congrats on the Top Quality video!!! Paul
I’m in the market for a weld on thumb for my bucket and wouldn’t you know it one of my favorite RUclips channels has a detailed video. You’re the best Andrew!
You are the master. Every time you use an excavator I can't help but wish I had one! So much more handy than a tractor for so many reasons. And you make it look like you can pickup anything from a small branch to big rocks or trees.
Funny you mention the boom swing. I use it in close quarters. It also is nice to dig a hole, say 5' wide and stay in one footprint with tracks. We have customers where damage to the property needs to be minimal
Thank you for the very informative video. What's up with the exhaust on the John Deere? It looks like it's not attached flopping around like it does. Maybe a repair video for that?
Having an Excavator is one thing, putting it through its paces like you can do is just amazing. I've seen many YT Vids on guys doing excavator work and I catch myself cringing saying "That's not how AC would do it." Keep up the great work, love the videos!
This comment should have more upvotes, I was looking to see if anyone had suggested adding valves instead of deleting a circuit. You had @Ronnie Wicks - smart thinking.
I been working at a equipment rental company and I’ve learned more on your channel about equipment then at my job. Most of the time idk what half the equipment is but I’m learning a lot from you and you explain everything so well. Keep it up
It's not a crazy idea. You could hook up a manual selector valve or an electric over hydralic selector valve to switch between the boom swing function and the hydraulic thumb function. It would make the same valve do 2 jobs. I have one on my tractor to add the third function for a thumb on the bucket. Makes the valve for the bucket curl work for the thumb too.
Now I know all about hydraulics and thumbs thanks Andrew for the lessons on thumbing buckets. You my friend should get your teaching degree make more money teaching greenhorns how to properly operate heavy equipment. good luck on all your endeavors, you are an endless person of knowledge.
Outstanding in its educational aspects. Different machines and importance and application of thumbs. Like your advice and about buying smartly, getting what you pay for. You’re a “kiss” guy too, “keep is simple stupid”, and it’s appreciated. Love the addition w/ Levi, has a real down to earth and video artistic value. You are a rock star!
Your exhaust on the backhoe seems loose? It's funny, you NEVER see an excavator with a thumb here in Scandinavia (i can't even find where to buy one), a lot of rototilt though.
@@markfryer9880 nope, I have been looking into it for my 3.5t excavator, I will have to build it myself or order it from (probably) across the sea (Canada/USA). But you do see Rototilt on almost every medium/large excavator at constructions sites etc. Checkout "Duckgirl86" on RUclips for some expert Rototilt work, and that setup (excavator, with utility wagon, rototilt etc) is very common.

It's one thing to show these machines at work, but you dragged these all out just to teach us about them. Thank you for the effort. Love the channel
Thanks

I can see it now - The Camarata Excavator Museum
Haha, had the same feeling on the intro. Combined with that 80s style retro music it was more than fitting. XD
Yeah.. after he retires with his millions, earned one dollar at a time!
I think Andrew will probably never retire. He has just too much fun doing his work.
With the Levi Skidsteer Commemorative collection.

Honestly making the arm solid and using the hydraulics for a thumb seems like a brilliant idea. I never would of thought of something like that.
When it comes to Yanmars, you're all thumbs Andrew. ;)
Andrew you can actually add a diverter to the swing function and still have thumb and swing like the new kubota.
You have quite a lot of machines now andrew well done 🇬🇧

That's true and it works great. You use the thumb to grab things by pressuring the thumb against the bucket and it holds fine.
Brilliant, very well explained, filmed and edited, and really enjoyable.

Probably should be glad Levi doesn't have thumbs, he'd probably eat more of your sandwiches when you aren't in your truck! :)
Pretty sure that was Lacey (?) though I guess if you have a dog as long as Andrews had Levi I'm sure you'd lose some sandwiches to him!
Andrew would put him to work if he had thumbs. :-)
...He would probably make his own sandwiches if he had thumbs ...lol
dogs like his, (and mine) on this level of communication and education don't steal anything anymore, they ask for it and eventually get it gifted.
I'm home alone with the dog and I find myself nodding yes to Andrew's statements...I need a vacation.

Your developing an excavator hording tendency, and I love it. LOL!
Manual thumb on my takeuchi tb015 has served me well for years. One less cylinder, valve, and hoses to give trouble.
Can you do a video about your hitachi excavator? I'd like to know the history on it and more general info about the machine.
speaking of thumbs, i gave this a thumbs up!
Great video again! That was a bad ass intro. Also take a shot every time Andrew says " thumb".

Hi Andrew, you live in a very beautiful region and you do a great job. A hello from Belgium
We had a B50 and did what you talked about with adding a tube where the swing cylinder was and adding a hydraulic thumb. Worked well.
Could you show how to fix those wobbly buckets? Most annoying thing on old machines
You just get new pins and bushings to take up the slack. If its bad enough you have to have the holes bored out first.
THIS WOULD MAKE A GOOD SHOW
Probably ran them without bushes in in the first place.

I operating most them quite often. I started watching and I became hooked on your RUclips. This is my first time writing a comment about the videos that you created. I am impressed with you knowledge of making videos. I have watched everyone that you have made and looking forward to more from you.
Rev. Ronald N. Allen
Thank you for teaching us how to do a lot of different things
That's an innovative way of paying for new tracks for the Excavator! 25 track pads at $50 each, minus shipping is a good chunk of the cost of 2 tracks!
Levi said,"Is there bacon involved with this?" !!! Love that dog!!
Build a carport for your line of excavators, bring the boys inside
Danye 👍 at a beginning: at a lineup (some people barely have one excavator) you my Sr. Camarata have whole fleet of it 👍

He has one, just not on the lower part of his property.
From an old Vocational Teacher. This may be the best video you have ever made. GREAT examples of thumbs; WONDERFUL progression of the thumbs with advantages and short Cummings of the samples, Quality reviews and recommendations!
An option I have just come up with on plumbing thumbs, “I'm doing this on my current thumb build” evolves plumbing the thumb into the bucket curl cylinder hydraulics. Plum the top hoses into each other, plum the bottom hoses into each other. Then put a electronic hydraulic valve inline of the top hoses. Install a electric momentary switch onto one of your hand controls. When you want the thumb to move, press the switch; both the bucket and the thumb will open or close with the switch activated, let go of the switch and the thumb will stay at this position.
Again congrats on the Top Quality video!!! Paul
I’m in the market for a weld on thumb for my bucket and wouldn’t you know it one of my favorite RUclips channels has a detailed video. You’re the best Andrew!
16:23 It would be nice if the door was motorized! You could an episode about it.. I believe it would be an easy job for you
You are the master. Every time you use an excavator I can't help but wish I had one! So much more handy than a tractor for so many reasons. And you make it look like you can pickup anything from a small branch to big rocks or trees.
19:12 That karate kick though!
Funny you mention the boom swing. I use it in close quarters. It also is nice to dig a hole, say 5' wide and stay in one footprint with tracks. We have customers where damage to the property needs to be minimal
That intro shot was just epic Andrew.
Me and my brother made a hydraulic thumb for his excavator attachment on his tractor. It was a good learning experience!
I have heard you can use the side to side function with a selectable valve to do thumb and then change valve to do side to side
A very nice video for people that don’t operate minis every day. Thanks Andrew!
Thank you for the very informative video. What's up with the exhaust on the John Deere? It looks like it's not attached flopping around like it does. Maybe a repair video for that?
Having an Excavator is one thing, putting it through its paces like you can do is just amazing. I've seen many YT Vids on guys doing excavator work and I catch myself cringing saying "That's not how AC would do it." Keep up the great work, love the videos!
You could add a diverter valve to the offset spool.
This comment should have more upvotes, I was looking to see if anyone had suggested adding valves instead of deleting a circuit.
You had @Ronnie Wicks - smart thinking.
I been working at a equipment rental company and I’ve learned more on your channel about equipment then at my job. Most of the time idk what half the equipment is but I’m learning a lot from you and you explain everything so well. Keep it up
Thanks.
Everything you ever wanted to know about thumbs but were afraid to ask...Good job!
I had never paid any attention to excavator thumbs. I just assumed they were all hydraulic. Nice job , informative. 👍
So I woke up five minutes before you posted and went back to sleep. Im here now though.
It's not a crazy idea. You could hook up a manual selector valve or an electric over hydralic selector valve to switch between the boom swing function and the hydraulic thumb function. It would make the same valve do 2 jobs. I have one on my tractor to add the third function for a thumb on the bucket. Makes the valve for the bucket curl work for the thumb too.
Thumb college 101, love it.
Every time I see another one of your excavator videos, I wanna run out & buy one for myself. Excellent video production.
Make sure you turn your ad-blockers off for his stuff guys and gals
There are only two RUclips channels worth watching. This is by far #1.
Been waiting Andrew for this vid! Cheers. All the way from New Zealand...
Kia Ora fellow kiwi your the first New Zealander I've come across in any of these videos comments section, Andrew's the Mantis aye!!!
nick torea
Kia ora bro! Absolutely! Wealth of knowledge.
What do you do for a job Nick?
I'm a machinist by trade.
Builder, plus mini excavator operator. Kapiti coast area
What a crack up I live in Masterton your practically my neighbor with the Tararua ranges as our fence.
It must be your youthful energy that gets you to go into such detail and great lengths to show us how these things work. Awesome vid!
Interesting videos your knowledge is outstanding from a UK follower
Now I know all about hydraulics and thumbs thanks Andrew for the lessons on thumbing buckets. You my friend should get your teaching degree make more money teaching greenhorns how to properly operate heavy equipment. good luck on all your endeavors, you are an endless person of knowledge.
Another great video Andrew. This Texas rancher enjoys your videos.
Hope companies adopt your findings,and learn by them .well done Andy
Adding a hydraulic thumb would make a great video. 👍👍👍👍👍
Outstanding in its educational aspects. Different machines and importance and application of thumbs. Like your advice and about buying smartly, getting what you pay for. You’re a “kiss” guy too, “keep is simple stupid”, and it’s appreciated. Love the addition w/ Levi, has a real down to earth and video artistic value. You are a rock star!
Your exhaust on the backhoe seems loose? It's funny, you NEVER see an excavator with a thumb here in Scandinavia (i can't even find where to buy one), a lot of rototilt though.
My thought exactly, I never seen an excavator with an thumb here in Norway
Not even on demolition excavators? That is were they are most likely to be found here in Melbourne Australia.
Only a few rototilt buckets still fairly rare.
@@markfryer9880 nope, I have been looking into it for my 3.5t excavator, I will have to build it myself or order it from (probably) across the sea (Canada/USA). But you do see Rototilt on almost every medium/large excavator at constructions sites etc. Checkout "Duckgirl86" on RUclips for some expert Rototilt work, and that setup (excavator, with utility wagon, rototilt etc) is very common.
5:15 paint a line across the thumb mounting slide onto its base when the pin is in, then it'll be a lot easier to line up after that.
Great instructional video thank you Andrew.
that intro, my god
It took a 3rd time watching to give me Top Gun vibes lol
