Rebuilding An 80 Foot Boom Lift Alone. Is It Possible? JLG 80HX
ฝัง
- เผยแพร่เมื่อ 3 มิ.ย. 2024
- I am finally ready to start putting the boom lift back together. I've done it all alone up to this point, but putting it back together is a different animal. Is it even possible to do alone?

glad i'm not the only one who puts things together the wrong way and has to take it apart again
I bet there are many who do it twice, but only a few are so honest to admit it, Embeded Fabrication.

I just wonder how much oil the big boom cylinder can hold, John.
Do you have an idea?
Never in my 52 years have I ever thought.....I just have to watch the maintenance on a JLG lift, but here you are, rocking it, and I am riveted to my laptop......really good work outta you.
I´m 68 and did the same 😱and had a lot of fun.
Gerhard from Wiesbaden Germany
Yep 56 and the same here 🤦♂️
Said it perfectly. Is something about the way he describes in detail, has a good plan and carry’s it out. Plus he keeps in the little mistakes like we all have delt with.
I have to tell you this series of yours on this boom repair is the most interesting thing I’ve seen in quite awhile. Good job!
Have to?
@@mwilliamshsI'm going to be the dumb guy that asks the question. What is wrong with those words? I'm sure I'm overlooking the simplest of things.
I don't have to explain it and you don't have to be dumb but Bob did "have to."
It's false sincerity. "I must ask you..." Must you? "I saw it and just had to have it." You had to? Really? "I have to tell you..." You have to?
@@brian_2040 There is ALWAYS that one Darren or Karen who's blessed us with their Grammar Pedantry Syndrome! Such a wonderful compulsion that overrides one's brains natural response to mind their own and instead engages their mouth or fingers on a keyboard to correct everyone's grammar mistakes, such as mwilliamshs just did to you and 'Ol Bob McDougal... They sure make for some marvelous joyless company Brian!!!
Yup - Spot on !
No one is more resourceful than a determined farmer.
Mad respect to the man who can call himself an idiot in front of everyone !
Edit 1: thanks for the new mic.
Edit 2: Wish you a safe usage :)
Nothing more satisfying than making something work better than you found it
What a job well done
Engineer: "If it ain't broke, don't fix it!"
FC101: "Yeah, but you might not find out it's broke *until* you fix it!"
Also, "If your life depends on it, make sure it ain't broke!"
@@FarmCraft101 Well where did You leave "no risk no fun" behind on the way here ....? 😅
Or you could fix it until it’s broken
Or until it breaks while you are up in it....
Great video once again, I am struck with awe at John's talent, a very clever thoughtfully guy. Plus I always have a chuckle at some of the antics. Well done indeed from a guy from scotland😂👍
You're series on the boom lift was amazing. It still amazes me as to how many things that you can do. Even when you don't know something, you figure it out. I love your channel, my favorite by far.
I sat here and kept saying, "This guy is an animal", over and over. I am absolutely impressed. Thank you for sharing this with us.
Over the years I have followed many channels here on YT, but I have stopped that, I was just watching what was recommended or if I was interested in something. But this channel changed that, when I see a new video I drop everything and watch it full. They are a good combination of learning something and fun. Good job, hope you keep this up man.
What an exhausting series 😂. The fact you did this all yourself is pretty damn amazing. That Arbor press is a nice piece of machinery.
my friend had one of those and its amazing when you need it. the amount of things you can do with it.
Yes, your new mic sure is much better than the camera mic. You did a fantastic job rehabbing the boom and can take a lot of pride in a job well done. Blessings to you.
JOHNSON! Damn son, your grit, determination and willingness to get er done is admirable. I come from a line of Polish immigrants. Farmers, entrepreneurs and alcoholic's. All forged there way and never found a challenge to great to overcome. It's just great to see that in someone with a positive can do attitude. Some of the young fellas who watch your show are visual, common sense learners. Just watching how you approach a challenge with calm logic shows them a realistic approach to dealing with life's challenges.
Great job Johnson, thanks for your on going .JOHNSON! Damn son, your grit, determination and willingness to get er done is admirable. I come from a line of Polish immigrants.

I am an old fellow. My dad was born in 1906. He had a certain way of doing things and safety was always secondary to cost. I imagine had he needed to replace a vital pin a nail would suffice. He did make it to 82 though so apparently luck is a thing. In any case I really appreciate how you do things right. Cheers from Canada where there is finally a small patch of grass showing through the snow. ~ulrich
Hi there,how is everything going on with you over there in Canada? Love your comment section, to be honest I'd love to know you more better than this, that's only if you don't mind leaving me a reply?
I really love your sense of realism: "Hey, what an idiot!" Makes me watch every friday again.
don't have a farm, don't have a lift, still following this series, biting my nails even when the fire occurred, congrats, I mean it, you are the kind of dude I like
Very awesome! Congratulations on a successful fix. Also, I think your price estimate is way low. I'd guess more like $40K to $60K.
Exactly what I thought!
Same here 40-60k
I'll bet that you're stoked at getting this done, but not just done, improved! Great job, great series. Every episode was fascinating!
Guys take the second to give John a thumbs up. Imagine the amount of work it took to produce this video on top of recording everything it literally takes less than a second to give him a thumbs up.
After Watching the Cylinder Repack by Yourself. I had no doubt you’d get it Back Together
I can't believe you didn't get someone to help you with this job, but I understand your point of view on it! Wow...good thing you've got a lot of other tools around! This whole batch of 80HX repairs has been quite the project- kudos to you for tackling them! Made a great series! Now...what's NEXT?! 😀
Quite the repair saga just to replace some seals, clean up some surfaces, and inspect the inside of the boom. Can't wait to see what jobs get done with it in the future.
Congratulations Doctor, the patient survived!!
The old mastercard ads apply here, XXX$$$ for this, XXX$$$ for that, the whole machine working - priceless.
That relief valve is a very likely culprit. You have done a great rebuild on this machine. I really appreciate your Stick To It ness that to many people lack. That machine is priceless for your way of life, and you'd regret selling it.
It would seem to me that there are only two options. That valve is out of adjustment or the hydraulic pump is not creating enough pressure. Surely it was originally engineered for that operation plus margin.
Does anyone know if it's actually supposed to retract when it's extended horizontally with all that deflection? Think about it, it's typically used to reach heights, so extending requires far more force then retraction. In most use case scenarios, gravity will be assisting with retraction.
In trying to retract it horizontally, you remove the gravity assist plus add a huge amount of resistance with the boom pieces jammed together from their own weight. 🤷♂️
@@blaircox1589 I am thinking in terms of a fork lift. I would think with a piston that size should move 20K pounds with ease. The point of deflection does cause more resistance but it seems it should be able to overcome. The boom did extend out horizontally, but will not retract. Retract lever itself may be out of adjustment.
27:45 LOL somebody call OSHA... ok actually joking aside that looks pretty dangerous, I'm really glad you have your brain in your head when you do this stuff. I would 100% have done the same thing - tried moving it with my foot while gripping on to the tractor's backstop expecting to fall, maybe. A controlled accident is always better than an uncontrolled one 😏
You aren't an idiot by yourself. You've got plenty of company. Congratulations!
Rigger Advice; Use manilla rope for pulling or hanging elements that require precision. Mamilla stretches very little compared to synthetic/plastics rope. Manilla is cheap and considered consumable or short life.
The worth of your machine as it sits “ priceless”!
This was an unbelievable series, super job! It was so interesting to see how it actually works, glad this giant project worked out just fine. I’m sure it’s worth more than you paid now! Thanks for the episodes!
You caught the poor thing on fire, you gave her a lot of TLC and needed attention. You need to thank her and yourself for a job well done by investing in some spray paint so you can maker her look really good. I KNOW it doesn't affect function, but you'll smile even bigger every time you use it, and it would be a nice reward.
I'm SOOO glad you got it all fixed and everything works well (except the retract bug...you might try Dean's suggestion)
There's nothing better on youtube then one hour John's video doing some stuff on his farm
I am super glad that you took MY advice.. Yeah Yeah I know others said the same thing... How would we be able to get thru a Friday without a video from you... Jumping off that lift into your lake looks like a blast....(for young folks)
On the RETRACT mode you can hear it blowing over a relief valve... Just need to adjust that valve higher ....you can also just connect a gauge to see what pressure you getting on the lines to compare but its def the best place to start....oh yes and also WELL DONE!!
I was worried. I didn't think this summers swim and dive party was going to happen. I've got a rotisserie for doing a whole beef or hog over a fire pit. We'll bring the rotisserie and some potato salad, you pick put one of the cows for dinner.
3/25/23; ..just watched your final assembly of yur long boom manlift. Wow! What a ton of work & waay lot of guts & super good attitude to take-on a disassembly, repair & (perfectly) reassemble this big, heavy & long...long 3-nested long boom manlift! What a fantastic job you have done! Thanks for showing all we YT viewers how you did this work.
Now, maybe you & 3 amigos you mentioned are going to start a 'how to fix a long boom' channel. I know Jesse Muller up in New York just bought a used unit (just?) like yours. Jesse mentioned your channel & activity so between all of you very talented guys, another YT channel specializing in boom lift repairs could be established. FYI...thx again for 📹 filming entire process. Much enjoy your channel. Stay safe & carry on!👍👍👍👏⚙️🔧💪🍷😊
I like your style Sir. The most common thing you’ll hear me muttering when doing jobs is ‘you utter t**t’ - at myself - as I make numerous stupid mistakes along the way. So hearing you admonish yourself is very familiar. The only way not to make mistakes is to never attempt anything. Hats off to you for this monumental and daunting job!!
from playing with Johnsons to playing with huge members this channel has it all!
have a great day :)
👍

"Half-booms as you know, are like gravity - All it takes, is a little push"
"Everything burns"
Ingenuity at it's finest. You are a great thinker.
Excellant series on the JLG! I enjoy that you show the screw ups as well as the pluses. I laughed at your discoveries of things not being right, only because they make me remember how I felt when I screwed up and the things I mumbled, sometimes out loud. Can't wait for the next video.
Very good work!
There's a lot of clever mechanicals going on in there. It's refreshing to see someone who prioritizes safety.
It was really fun to watch too!
I had to laugh at the beginning when you said "this is like a personal challenge", what went through my mind was "no no no, it's not a personal challenge, we all know it's a personal vendetta at this point" haha😁
How can 1 man take on a job like this and make it look so effortless? CGI I though to myself. But then one step at a time the fog begins to clear, its not effortless of course just sheer determination and know how and one hell of a lot of grit. Your videos are a true gem to watch for any guy or gal that likes to tear something apart and put it back together. Thank you for taking the time to share.
Nice to see how much active and passive safety is engineered in
Congratulations John! The number viewed was just about 12,000 when I watched so that made 12,000 smiling face on a Friday afternoon. We are all very proud of your accomplishments.
Drama, tension, suspense! This rebuild had it all. Vastly entertaining and informative.
If work is what makes you happy, you must be ecstatic! I knew you would get 'er done.
AWESOME SERIES! I would never attempt to do something like this by myself. My hats off to you.
You did a amazing job. You should be proud. Especially doing the whole job solo
Lapel mic worked very well.
My wife says you can never ask for help, why don't you just ask for help. I agree there is something about accomplishing the job by yourself that is satisfying to the soul. Great job. Thanks for all you share.
Absolutely brilliant!
It’s amazing that one man could do all that on his own without help. Even though TH-cam gave me like 35 annoying interrupting adverts while watching, this really was an enjoyable video to watch and each video has been exciting.
I hope you continue to make more videos like this, accomplishing massive complicated projects.
God bless you John - all the best from Great Britain 🇬🇧
Get you tube premium, I had no interruptions.
You will never top this repair.,nice going.
AOC is God's daughter too! She tells us she is God's gift to mankind.
Amazing job Sir, I hate to think how much that job would have cost at an approved service center, and you have the satisfaction of knowing the work has been carried out correctly.
Most would have quit when the big pin wouldnt come out. From those that were left the fire would have put them over the top. You're a tenaticous man. Great job Jon.
You crazy bastard, I really thought you'd bitten off more than was chewable and it wouldn't get done, especially after watching the dismantle.
I am really happy to eat my words and congratulate you on a job well thought through and well done. I hope you get many years of service from it. Good on ya sport.
Your problem solving skills are amazing, I’m glad it worked out for you. It will last probably for the rest of your life and then some. I’m glad I found your channel.
I guess this is one of the best channel..
I'd love to know you better, that's only if you don't mind leaving me a reply
great job john you tackled something not a hole lot of people would never attempt , awesome you are the man.
That was astounding. You are my idol. Thank you for sharing the whole process. 99.99% wouldn't even tackle that job. Having a rebuilt boom cylinder is worth at least $35,000. Start adding the rest of the repairs and that beast is worth at least $70,000. You will have to work it like a dog for many a year to cut into that worth mainly because of the quality of the work you did on it. Only thing I can suggest is out of the weather storage for a valuable piece of equipment.
Best medicine after Friday morning knee surgery is a FarmCraft101 video. Thank Jon!!
I've loved this machine since you brought it home. I think if you hadn't bought it, it would be in a scrap yard. Have enjoyed all the videos on it and glad you didn't get hurt doing any of it :) What a great accomplishment to have done all that you did.
Best hour of the week.. really enjoyed that 😊 Keep showing things you forget to do or put in backwards .. makes you seem almost human, like us 😅😂
Thanks John ❤
I highly recommend you make sure your hydraulic system pressure is set properly, and then start checking all of the other function pressures. You can find all of the procedures in the service manual on the JLG website.
Every time you refer to yourself as an idiot I start laughing. I fully understand your pain.
When pulling the boom in with the winch, it must have been unnerving when it lurched inward, instead of slowly sliding in.
Love the way you show the journey of this repair - the problems, the solutions and that you don't always get it right the first time. One seldom does with old equipment, but by having the S.M.A.R.T. (wuuhuu!) and using some good tools, the reward of fixing something yourself is often that more sweet. Good job! I don't have any equipment that big, so seeing you work on fixing it, is good entertainment for me! 😀 "Does it need fixing AND can I learn something fixing it?" 👍👍
Never did I ever think I'd get so interested and invested in a boom lift. Lol. Thanks for a great video series
Don't know how I ended up at your channel one year ago, I'm by no means your target demographic as an mid thirty European with no clue what you're doing half the time.
But I enjoy your content as weirdly relaxing, helps a lot at dark times to keep the mind calm.
Thank you for that
You’re one helluva Mechanic!
⭐️⭐️⭐️⭐️⭐️👍
By far my absolute favorite channel on TH-cam. Great work!
Congrats John that was a mammoth fix that the majority wouldn't attempt on their own, so you my admiration for what you did
Well here I again at 4:30 AM watching a FarmCraft101. Totally amazing.
Excellent work, I really enjoyed this series. I thought you were nutts to even consider it, but when seeing the condition of the seals it was totally worth for your peace of mind. It was great watching you think around the problems. Well done..
Congrats on successfully repairing that lift!
A big job for 1 man.
But you conquered it.
I take my hat off to you Sir.
Bravo !
You and your "THAT's not going anywhere"... is a motto my family has lived by for years.... and it worked great... until when my parents got into their 80s and I had to renovate their bathroom. They wanted a walk-in tub and pocket doors... they needed enough space to use the wheelchair in the bathroom, basically. Have you ever TRIED to demolish a bathroom renovated in the 70s to the standard of "THAT'S not going anywhere!"? Yeah... the floor, the tile on the walls... pretty much the whole thing I had to cut into 1 foot square pieces in order to get it all out of there to make room for the new stuff. It took 3 times longer than I thought... and the dumpster ... well, I had to order a 2nd one because the first one was too heavy. Yeah... sometimes we even gotta think about whether stuff ever WILL go anywhere... lol.
Such a great project to follow along with! It’s so rewarding when you do a stretch job and it turns out. This was a MASSIVE job to do on your own! So cool, congrats!
What a great ending to the series, I couldn't wait to see this video ! Never doubted that you would get it done , great work John !
You buddy deserve Field Mechanic of the Year for taking on something that huge, with PF-7 issues (pucker factor level 7 - the fire) along the way, seeing it through, with no injuries, everything working, all by yourself. Sincerely from a mechanic that's pretty amazing 🤜 Motor still sounds great too 👍
Great job John, very brave of you to take on such a daunting job. I can’t imagine how good it feels to have that over with. You’re lucky to have friends that you can rely on for advice. Looking forward to any video that you may put out.💯‼️
John what's left to say, what can't you do. I don't impress easily ,but the repairs you did on the boom lift is impressive and doing it by yourself is doubly impressive ,I haven't found anything on u tube that can compare to your total overall content outstanding workmanship
I was just telling my significant other how much ive been enjoying this series. Thanks for the new mic. Its much more enjoyable to listen to.
Congratulations on getting her all back together, John. Thanks for showing us that you got up in it to take down the Christmas decorations. I thoroughly enjoyed the series on this rebuild. Amazing job, well done and a success to boot!
Amazing individual effort!! Extremely interesting...great content for a video. You created a real nice luxury for residential use and now potential for contractor certification.
@55:54 "I don't have anything else to fix on this thing" Boy, you sure like to live dangerously. Good luck with that.
At your use of loctite you should be getting a sponsorship from them. All your use of it makes me want to loctite everything from my truck to my computer chair.
Amazing job, Jon! This is so inspirational. Great work and a joy to watch.
I was so scared this was going to go bad trying to get these books and cylinder back in place. Great job there Jon!
Really really love this rebuild. It's a "so that's how everyday bluecollar solo's a stupidly hard but not difficult repair" series that we really get to learn a lot from. Fingers crossed the pressure relief valve is a really simple fix for retract!
What surprised me the most: It's all wear pads, no roller bearings for that much weight/extend.
Great job! "You’re a better man than I am, Gunga Din!"
What an epic job, well done, Jon!
Fantastic stuff Jon, that's quite the project!
(Senior design engineer here).
I design cranes for a living. The amount of pressure that wear pads see tele out that far is extreme. It’s easy to calculate. Moment arm times the area will give you psi on the 2 top wear pads.
If you ever get into the wear pads again. Think about having some Teflon impregnated nyltron wear pads. We have all ours custom made per machine by “ws Hampshire”. We have had stick slip issues with out booms but we’re greatly resolved when we went to Teflon wear pads.
I'm glad to have company amongst those who assemble 3 parts then disassemble to include the forgotten 12 parts that go behind/between them.
Spare parts... included with every machine!
Nice job Jon, I admire your tenacity.
You Sir, are an absolute CHAMP for doing this on your own, and getting such a nice result. Hats off !
Tears down and puts back together a multi-ton boom lift all by himself. Gets two guys to help him lower some Christmas lights. :).
Now seriously speaking, watching you disassemble that thing I was thinking: "There is no way he is puting that back together". Nevermind the technical chalenges of puting it back together alone, it's admirable the sheer quantity of work you are able to accomplish.
I take an hour off work every time you post a new video. Can't get enough of this
Well done! Such an amazing job; you must be so proud.
You have done a sterling job mostly on you own as stated previously, you are full of great ideas to overcome many mechanical obstacles and you are most interesting to watch you would make a good instructor.
