Good work. I also like that you include the failures in your videos. Too many people act like everything worked first take which is pretty disconcerting for anyone trying to do anything similar. That's failures have massive value.
Good job Waldo its funny to watch someone with no experience do my job working on heavy equipment but I can say I give you a big props for your ingenuity and determination to make it work its what we do everyday solving problems wayout in the middle of no where and making something out of nothing. My generation is losing this type of work in favor of office jobs and its sad to say men aren't like this these days so good job keep up the good work
Thank you! It's pretty challenging working on heavy equipment, though I'm sure it gets easier with experience and the proper tools 😬
I work in an office-no insult received!-and even in an office, men and women seem to lack the critical thinking skills it takes to reason out a problem, with paper…or wrenches. Waldo also impresses, for his tenacity and problem solving!
@@ChrisACiufo I always wondered if people in a office job had similar dealings with people that lack common sense I admit I don't know how they would or what kind of situation you would encounter in a office, but In my job if you lack common sense alot alot of times you get hurt beyond repair even die and there is no one to call, there is no one coming to help and no one is gonna hear you. On the other hand I wouldn't wanna be anywhere else I was born into this dangerous job it is all I know how to do and I love every miserable minute of it I don't know how anyone works in a office tbh bigger props to you for being able to do a office job seriously cause I couldn't do it much respect
@@ER12 As they say: "can't fix stupid"! People don't die if they can't think clearly or make stupid decisions in an office--but lots of money can be on the line.
How long have you been turning wrench?
Suggestions for future reference... 1) Disconnect both hoses from the cylinder, so as you're pulling out the rod, the other side of the piston doesn't create a vacuum. 2) The ratchet you were using to pull out the rod was pulling at a downward angle. Ideally, you want to pull the rod "straight" out. 3) One option is after you have slacken the big nut, you can remove the entire cylinder and place it on the ground to work on it. That being said, I think these things are always a headache to work on. You did good for someone doing this for the first time.
Thank you for the tips! 👍
Good idea, thats why you're the mechanic and I'm not. Thanks
@@acme855 I'm not the mechanic, I just learned the hard way 😂
For future reference, beating around the circumference of the large seal nut, the one you made the spanner wrench for, may have helped in loosening ancient crud stuck in the threads. It's a trick I used when working on snow removal equipment where salt messed things up. Also works on hydraulic fittings. Use caution on fittings, have a helper hold a bigger hammer than the one you are swinging on the opposite side as an anvil. I hope that made sense, You seem intelligent enough to know what I mean. The shock of the hammer blows momentarily oblongs the circular thread. Hope I helped.
Thanks for the tip! I have to reseal the stabilizer cylinders next, so that might come in handy!
Videos like this really motivate me to continue pushing myself to learn new things and push past challenges. Great job Waldo!
Well done Waldo, especially without having all the tools. Looking forward to the next one.
Thanks, it was definitely a journey!
It was a stroke of genious to build/fabricate your own tool to get that cap part loosened up for removal!
I cannot wait until your next video in which you use your backhoe!
Well done, Waldo!
Im pretty late to the comment section here, but if you're ever in a situation where you need a big socket like for the end of the cylinder rod, there are tools called Slugging Wrenches that are quite handy. No air needed, and no giant impact gun. Just a closed end wrench that has a large striking pad for a sledge hammer. I work in a mechanics shop for heavy equipment, and we use them often. Also, those particular nuts usually go on with red locktite, so you usually have to use a torch to get them hot enough to come off.
Hi. I love this video. Watching Waldo work on this hydraulic cylinder (something I have not done yet,but will) gives me more confidence to repair one myself. Thx Waldo.
Thank you! I'm sure you can do it, just keep on trying and you'll get it!
Great example of mechanical bravery and perseverance. Well Done!
Heat and beat. Useful steps for working on old equipment.
Great to see you having problems and finding solutions 👍
I have been prepping to try my bucket cylinder..this has totally convinced me to just take it ti the shop and let them do it! Thank you!
(Said in slow motion) NOOOOOOO!!!!!!
No, but in all seriousness, I sort of regret bringing it to the shop. I totally could have done it myself, but I just felt time pressure trying to get a video out. Check out my video where I replace the stabilizer seals (ruclips.net/video/5uMxdIbbUHc/видео.html). It really wasn't that hard and you'll feel great after you've successfully learned a new skill! 👍
36 inch pipe wrench and snipe for the glan ring and the packing nut works every time
Great stuff man, you're giving me the motivation I need to tackle the projects I've been letting pile up
That's great, I'm glad to help! 👌
This is a great channel. Deserves way more views than it has. Good luck on continuing to grow it.
We usually weld a big piece of bar straight to the gland (the big threaded bit you were trying to remove. The heat frees up the threads and is simply cut off and cleaned up afterwards)
I am glad I found your channel. I enjoy watching you do things on your own and learning as you go. My dad always said if you do nothing, do it while learning something new every day. One critical flaw I see is when you are grinding. Please please please where a face shield with safety glasses. You should also wear a apron also. Grinders are great but when it goes wrong it’s usually very wrong. If it breaks and hits you , it will be a very bad day. Good luck in your channel and I see I have of videos to catch up on.
Cylinder packing is part of the job, yes it’s a lot of cleaning and seals but it’s not that bad to do. Now that you’ve had before and after you can see how it’s done. Yes we own a lot of big tools in heavy truck and equipment world but it saves us some on outside labor in the long run.
Your spanner wrench build was a cool idea, thicker plate and a 1-1/2” bar for the handle would have helped you but you got it done.
Not giving up and coming up with a better plan is the key a lot of the time!
Waldo on my D3 dozer lift cyl gland...four ft pipe wrench with 6 ft pipe. Used backhoe to push down...I admire your ambition..and again best of luck
Wow, that's a quite a way to get the job done!! 👍
I agree a young man as yourself doing what you have done is outstanding for these times. Job well done ! Oh I also enjoy watching somebody work as hard as I once did getting ur done . LOL
You showed a lot of determination in this episode!
When u welded that wrench onto the nut that little bit of heat helped u out big time ...sometimes a big hammer around the nut can help to but all said n done u got it off ..awesome job
You should remove the hydraulic lines connected to that cylinder first before trying to remove the gland nut. Relieves the hydraulic pressure. Makes things alot easier. Also never turn the unit on when you have any sort of hydraulic component torn apart like this. Even if you're just replacing a hydraulic hose. Stuff can get very dangerous with that high pressure. But hey you know that now. Cool video 😎
When you fired your tractor! I could see that hydraulic piston and ride assembly shooting into the neighbors yard or maybe through a building
Your video quality is fantastic, so clear!
I worked on hydraulic cylinders for a few years the special tools is a punch and a sledge hammer or a 6ft pipe wrench too also heat helps because they are always put together with lots of lock tight
Perseverance is your great asset. No challenge is to small for your projects.
At this point I must say, I am watching all of your videos.
I didn't understand the "Welcome" part of the beginning of your videos, but it was dumb of my part....
You are doing a great job! Well done.
Thanks, Sergio! No worries! 👍
Thank you for making Waldo lad
Peace n love from Cumbria UK 🇬🇧 ❤
Videos like this really motivate me
Great job making that spanner wrench .... At first, I thought it might be reverse thread, but you got it !!!! ..... Very Good !!!!
Another epic film , well done ,man that was tight but it's alive complete and working buy the look , can't wait for next episode very entertaining and certainly learned o lot thanks again
Thanks, Steve! I'm very ready to drive this thing next!
Great content and excellent quality video . I think your a natural , keep up the good work .
Good call to go to your local hydraulic repair shop to identify the seals. Nice video! We live and breathe hydraulics down in Alabama. Roll tide!
Great video Waldo ! I want to come and play at your house, you seem like a very nice good natured guy and you have the best toys. Thank you for posting your videos.
Thank you! 🤠
You did GOOD! Use what you have! Carolina Tractor ran an Hydraulic Express truck once a week and they had a driver that was 7 feet tall with a brother that was 7'1". Interesting to see him go through a 6/8 door! And drive a F-150 pickup. Truth is stranger than facts. A-PLUS!
Thanks, Lewie!! 👍
Great content Waldo. We had a stuck cylinder that we used air to push out piston...would make a superb potato gun lol. Keep it up.
You remind me of the coots up at Stagnant Lake Ontario that had a problem like that and solved it with a ten foot pipe welded onto a modified four foot pipe wrench. They know all the tricks up there. It was done in forty below weather too!
Looking great man
Waldo is the kind of guy that would have made a plasma cutter to make a wrench to fix a seal. Guys the real deal
Waldo I had the same machine three backhoes ago...they are animals ...but suffered from certain issues...there are no machines produced today that have cylinders the size of the dyna hoe..good luck with it and believe me I never had a job mine could not handle...it took three machine to find one that came anywhere near what the dyna hoe could lift
Yeah, I have to say the lifting capacity of the loader is impressive: 7650 lbs. according to the manual!
just saw the videos awesome it helped a lot thanks for making them
Glad to hear it!
Awesome video Sir.
Just add
Houston, "We have a successful launch" when that cylinder shaft popped out of the cylinder :)
Another video well done. Showing perseverance paid off.👍
Stay safe, Joe Z
Watch diesel creek he is a very capable young man and is self taught like you and runs into a lot of adventures like you I'm 67 yrs old and I've learned a lot from him he is well worth the watch ENJOY !
I had the same situation, with gland stuck to cylinder, I welded 2 5/16 nut to the end of gland with the heat from the welding plus a large pipe wrench with long pipe extension the came loose
Yahooooo! Ready for the next one
Nice work man 👍
Thanks, Cory!
I have 60´s Ford 4500 backhoe and i fought several days to remove the big nut from the end of big cylinder on top of the boom. All this seem so familiar that it almost makes me not wanna watch this. By the way, at least in my case the nut _was_ cast, just like the inner smaller nut (which in Ford is also threaded). Great videos you have, take care.
Thank you! Yeah, these hydraulic cylinders sure can be tough to work on!
Dont feel bad I spent days undoing a cylinder,just to find the thing I was hammering on was a lock ring (each blow was Tightening as the cap screwd off,fought me the whole way)...well done...if you dont give up, you will get there.
Wow that was not expected. That ram shot out like missile.
Bigger hammer, a longer handle for more surface area, for when you put the pipe on it. Also you could've heated it up with a blow torch to expand the metal some.
All’s well that bends well.
DYNAHOE the best TLB ever made
Next time to push a cylinder out? Do what Andrew did: Compressed air..... ha! Nice video. The only suggestion I had, was possibly fabricating the wrench to a full 360. Yes, you'd have to slide it over the end, but you gotta loosen that anyway... I think I'd also have some holes spaced around, that you put threaded rods through, and then? Anchor them to the main body, to keep the thing on the end. If they are very long (3 feet) they won't impede rotation until it breaks loose, then remove the rods, and use as you did. Still. Pretty amazing, as the Hydraulic Press Channel says? Pretty Good.
To loosen the large nut could have used a large pipe wrench and a 10lb hammer to turn it by hitting its metal handle.
Also, you could have fabricated a ring wrench and used a pipe to extend its handle in the same way you removed the cylinder end cap.
That’s bad ass, at first glance I wouldn’t even think you would know much about heavy machinery
I'm learning as I go 😉
@@WaldosWorld I have a 1978 160 too. I am not much of mechanic and a brand new operator. I have an issue once it warms up it stops moving. Subsequent also it leaks at the cooler so I have my headaches too. It runs like a top and in pretty good shape, but not usable yet.
That was a lucky exit.
Ah yes, the "good old days" of the start of the pandemic.
That sucker was on, its surely has been a few years since it was opened up. That engine of your machine sounds good by the way.
It would probably have been a good idea to try and wipe clean the inside of the cylinder as well as clean up those threads while the ram was out. Contaminants can just ruin your fresh seals.
Thanks, that's a good point!
Waldo please post part numbers for these repairs! I have a 1974 160B and need to do this repair!
Excellent video!
I loved the overlay of current world events and the syncing of the hammer to the music.
Haha thanks! For some reason, YT doesn't like when you talk about current events that they consider "sensitive" 🤷♂️
You make a good video.
I wanted to see how you installed the seals i have so much trouble doing that
best part was the hammer blows in time with the music way to go man
great content..
Good thing you put that padding there. You wouldn't want to damage the rod.
No kidding, that would be an expensive mistake!
Well that was an entertaining and life affirming episode of the backhoe chronicles (except when you had that piston pulling hard on those ratchet straps and you were looking down it like a guy looking down the barrel of a loaded pistol).
I looked up human in the dictionary. It said "see Waldo".
Hahaha can confirm; am human 😂
theres a guy in hooksett thats really good on the left heading north on 28 on a horseshoe road back in a industrial park. I have him do all my John Deere stuff. I get parts and drop off usually in a few days bam.
@21:00 Sweet!
Next time you may avoid paying $300 to Hyd.W.Shop by hammering the Lock Nut anti-clockwise at may loosen the lock Nut with the help of heating
in the future archeologists will puzzle over that too. cf Gary Larsons Far Side, "Cow Tools".
good tool remember righty tighty, lefty loosey
Don’t feel bad.. I would of done that myself honestly if you have to do it everyday or you had more hydraulic cylinders to do I would say buy the tools but since it is just one don’t worry about it I actually would of took the one on the end to I have a feeling it’s going to be problematic in the end but maybe not
These videos are hilarious! Very entertaining knowing what is about to happen. You clearly not the complete DA boob portrayed. I cringe with the lack of contamination control, but these videos are not a how to. Thanks!!
Bushings are another project
WHAT PLASMA CUTTER ARE YOU USING? BTW NICE WORK YOUR VIDEOS ARE GREAT GLAD I FOUND YOU. THE HOSE CLAMP WAS A GREAT WAY TO WORK THE PROBLEM.
I made a similar tool out of a BMW suspension part. It was still squishy with a 6 foot pipe so I simply welded a 3/8" rod from about 2' down the pipe to the top of the arch. You must get the give out. It worked immediately after that. I'm talking a 5" boom cylinder on my Cat 307 excavator. That all went great but now it is stuck right about at where the gland sits. Won't budge with a doubled up come along. Just when I thought I was on my way. Help! I'm a little gun shy on the idea of blowing it out using the hydraulics 😜
Waldo I’m sure you know by now..the torque on that nut is over 2000 lbs...but the other issue is the ability to hold the rod from twisting
Oh wow, I didn't realize it was *that* tight! I have to rebuild the stabilizer cylinders next, and I'm determined not to give up, so I guess I'll get a 10 foot pipe ready!
Well done! Watch out for the state of NH getting on your ass about all that hydraulic fluid... 😀
If anyone asks, it was all computer-generated 😉
you could have made a socket that big. we make spindle but sockets frequently. flat stock welded into a hexagon with flat stock welded across the back with a 3/4 hole cut in it.
16:38 my god. Way to persevere. You can always make a living designing obsolete tools for auction hoarders. 👍
Epic spud gun
And we wont tell the epa that you spilled any Hydraulic fluid okay.
Spilled like a quart of diesel fuel in the field one time in Wiscanistan, and the fucking by the time it made from my Platoon sergeant to my company commander, to field operations command to base hazardous materials disposal, then the epa heard about it, it was an entire hemtt tanker spill, or like 2,800 gallons, and it wasn't contained on a brim, it was in topsoil.
And yeah, I know they only take "2500 gallons" but fully wet they usually hold more than 2500. Either the tanks expand, or there is some kind reserve. Or the fuel metering devices on both the ingestion end (the thing putting fuel into them ) and the production end (where we fueled up trucks in the fuel) had some calibration errors.
I suggest you look on eBay for a 2 3/4" SLUGGING wrench. I have them for just such emergencys
I hadn't heard of a slugging wrench. Thanks for the tip!!
@@WaldosWorld Go look on eBay, you can buy one for a much less than a 1" socket set. I use them and you can't break them.
Heat the caps if they are being stubborn. The seals are already trash anyway.
5 years from now he'll be way better at doing this
I sure did learn a lot from that!
@@WaldosWorld yea 5 years is exaggerated but that's what I mean the more one does something the easier it becomes
You like to use the same music as Matt's off-road
Could you have made a tool??? Impressive stuff💪
Quick Waldo patent that projectile and get it on an Abram’s
CCE from Austrila does this work ll the time and is on youtube. Kurtis is a real enginer.
OK, to influence the algorithm, I say parley tickle tickle toe. Respond with your best "Mumble dog face to the banana patch". Show the love to this guy.
Hey even Andrew Camarata takes his hydraulic cylinders to the hydraulic shop for repair. You did a good job brother.
Pipe Wrench works on those nuts
Wonder how much to have shop do it
When I bought my tractor, I purposely DID NOT buy a backhoe on my machine. I was only interested in tilling garden, grading driveways or mowing fields. I didn't want a backhoe that I knew I wouldn't use.
Why doesn't your assistant want to be seen participating in your noble endeavors?
He's in witness protection 😬
Waldo please consider wearing your seatbelt over your shoulder as you are sunning the risk of ripping your shoulder off even when someone runs in to your truck from behind. I understand that you're tall - maybe the upper mount can be modified? Great vids BTW.
Depending on exactly how he was hit (or hit), the injuries would likely have been to his right shoulder, left upper arm (possibly shoulder joint) and right head. More variables would affect the cervical spine and cord. In short, you're right and we'd be wondering "where's Waldo" for a long time.
I like how you built the spanner wrench 🔧 to fit the cap on the cylinder but why didn’t you build a wrench to fit the nut on the rod or even a socket out of that same 1/4 plate draw it out and use 3 pieces welded together add a piece of pipe and the a old socket that you have several of. My deceased dad and I’ve had to build several tools and adapters to make parts work that were meant for different machines. PS wish I had a plasma cutter it sure would’ve made making tools and stuff nicer especially since I’m not very good at use a cutting torch, I move either to fast or slow.
Yeah, I definitely could have built a socket for that. Next time!
I came here to say the same thing. It used to be my full time job back in the old South Africa. Because of sanctions, we had to make all sorts of plans and do without the “correct tools”.
Good to see you persevere! Great videos Waldo! 👍🏻
where did you get new seals????
Those are like working on Landrovers, require$ $$pecial tool$
All you needed to do was buy the appropriate size spanner wrench.
It's $95 just for a 1 inch drive, 2 3/4 inch socket. One socket.
