Boom Lift Engine Repair. Can I Finally Fix It??? JLG 80HX. Ford LRG-425 engine.
Вставка
- Опубліковано 6 лип 2024
- This old Ford engine has really put up a fight. Can I finally get it running properly? I review what I've done to it already, then we check the compression, fix some wires, put on a manual choke, try several cold starts, check for vacuum leaks, take care of some cows, and finally install a manual choke cable kit. Is it fixed? But there is more work yet to be done...
Regarding disassembly of the boom, I should have explained more. All commercially used lifts have to get an OSHA inspection annually, and that inspection requires a boom teardown within the last 2 years. So every lift on every jobsite and every rental place has had the boom serviced within 2 years. JLG recommends servicing the lift if the machine is left sitting for longer than 6 months, for what that's worth. Not sure sitting idle would really warrant a teardown, but the last inspection this machine had was 2009. That last boom teardown may have been 2007, so 14-16 years ago. And the boom isn't working properly: it won't fully extend and retract properly as shown in a previous video. Finally, the telescope cylinder in the boom does weep a small amount of oil. It's just a matter of time before this will need to be done, I'd rather do it now and have it safe for all the upcoming jobs rather than wondering the whole time and then doing it. 🤷♂️

A huge thank you to all the folks who had suggestions, you guys really helped me get this engine fixed up. Update: I'm making progress on the Nissan project, and will definitely have a video on that ASAP, but it is taking some time getting it fixed, programming the computer for the new transmission, identifying the right student, then I need to do and film the giveaway and edit it all into a video. Actually, I've found MANY students that are well deserving of a car, but at this point I will only be able to do 2 cars. I definitely hope to do more in the future. Hopefully the giveaway videos will get millions of views and that will allow me to keep funding more giveaways. Cheers everybody, and have an awesome weekend!
Please review video at 11:38 for arcing inboard forward side of valve cover.
@@CaptainBaja Not a spark, just light bouncing off a notch in the back of the cam sprocket messing with the camera. Right between the oil cap & intake hat. No worries boss
Should you service the boom? Yes. Will you regret it? Also Yes. Will you ultimately be happy you did? Thrice over, yes.
I watch on my computer while eating lunch, so that probably made it a bit easier for me to to see the sparking. Glad it might have helped out. Thank YOU so much for all the great content. Appreciate the discretion in not sharing names, but it's fine by me. I have a channel on functional 3d prints if you're interested in checking it out: FunctionalPrintFriday

Having watched all your repair videos the person who can tackle disassembling, inspecting, lubricating and putting that boom back together is going to be you.
And Mr Johnson
That mini-roll electric tape trick was genius. Gotta steel that one...
Yes! Do the chains! Not necessarily because you need to but because I just love watching you fix things and explain everything! You are just wonderful!
You have joined Mustie1 as my favorite content providers when it comes to motorized/hydraulic repairs!
If you ever want to add a remote choke, I've used cheap remote door lock units. Same for fuel pump priming. Just set a lever on the choke with stops, then stick the door lock actuator on it. And just stick a fob up in the basket.
Brilliant idea!
Forklift engineer for over 30 years, we refer to these as "whack a mole" jobs. Fix one thing and another pops up. 10/10 for persevering and getting the job done.
Curiosity killed the cat, but satisfaction brought him back. 😊 Buenos Aires, Argentina.
Personally, I think you'd be nuts to pull that boom apart. But, I sure would enjoy watching you struggle to do it!
BRO!!!!
I’ve been a mechanic for almost 30 years, worked on almost everything with an engine it at one time or another!
I am now an A&P Aircraft technician, and the “mini tape roll” of electrical tape, I have never seen before, and think is freaking ingenious!!!
I want you know I saw it here first, and will be using this absolutely and unbelievably simple and ingenious tip/trick on multi million dollar passenger jets in the future (where required and legal, have put that disclaimer in here!) and everything else I work on including things around the house and my race car!
I’m very shocked that I haven’t seen this before and impressed with it!!!
This is the most literal expression of "The grass is always greener on the other side of the fence" I have ever seen .... Good Luck Big Mama!
Since the chains aren't used like on a bicycle or something with it under constant load and rotation, I would be inclined to leave that project alone. Thrilled to see you got the starting/running issue resolved.
I agree, chains will be a-ok. But I hope he pulls it apart anyway cuz I wanna watch the vid.
I am 99.9% sure the chains would just need a quick inspection and grease but that main cylinder must be due a rebuild considering the state the rest of the machine came in.
@@Adam_Lynn Copy that, that main cylinder is original (maybe) then it is overdue for a seal kit
A detailed boom chain inspection would make a good video. In the meantime, keep a rope ladder in the basket. ;)
Aaaand mr Johnson makes his return. I am way to happy whenever he turns up. Maybe I'm still 12 mentally while actually turning 60 this year...🤔😂🍻👍
You are definitely going to regret the idea of checking the chains while doing the job but afterward you are going to be happy that you did 😂😂Awesome that you got the engine going right again ! Keep up the good work always excited for when you post!!
You have a knack for making your struggles fixing things into very interesting and entertaining viewing. I really appreciate your demeanor and humor. I don't want to see you struggle but when you do you still make it look like something very interesting to watch. Good luck with your decision and if you do do this I will be right there watching. Actually I would like to be right there helping.
22:38 That face 😂 I appreciate these videos. I'm a country boy stuck in the suburbs and watching these is like a visit back home
Glad you got it figured out. The true troubleshooting videos on UA-cam are the best. SMA, Ivan @ PHAD have a bunch of them. Love to see people work thru a problem and actually diagnose them. Not just throw parts at them. Thanks for bringing us along even if you were struggling.
Watch wes work is among the best
@@lorenzo6045 Agree with that WWW. I really like FarmCraft, but WWW is on another level.
@@CWhitmer22015 I watched 4 WatchWesWork videos now... how is he on another level? He even starts the parts-cannon right away, instead of doing the diagnose first. I would agree with South Main Auto Repair (Eric O.), but WWW seems pretty much on the same level like FarmCraft in terms of how he approaches such an issue. Did I just get unlucky with my videos?
Thank you for another great video. Love your fur-babies. I asked Father and prayed if he might help momma cow with her hip pain❤️🙏😞 He always heals me if my wife prays and he always heals her if I pray. Hopefully he’ll heal momma cow❤️
The mini roll of tape is PURE GENIUS
That "mini roll of tape" is a Great idea.....never would've thought of that one. 😆 Great video as always 👍
Choke issue solution gave all of us relief, not just you! Fantastic! Great perseverance!
I know you’re worried about starting w/o choke when you’re in the lift. An easy solution would be to use RC solenoids. You’d have to work out supplying electrical for the solenoid, but compared to other stuff I’ve seen you do, it would be right up your alley. Solenoids that control the throttles of RC cars and planes would work. It’s exactly the motion of the new manual choke you put on. Hope that helps. ;-)
It’s not the struggle alone that most people watch you for. It’s the ability to not give up and overcome that struggle that people watch you for. It’s rare to see people like that anymore and the ones that have that trait in us but not the means or ability to do what you do watch it for the slightest bit of that feeling you get when you finish a job most would just give up on and buy something new instead.
I agree
You may not know what you are doing when you start into a project but in the end you show and teach very well. Thats why I enjoy your videos. And you make it funny once in a while. 😊 Not running down rabbit trails too much is nice.
Please thumb up so John can see this idea for a remote choke. In order to get platform choke control, you may be able to buy a cheap RC 9 gram servo and control it with an RC servo tester on the platform, its just a single potentiometer and very cheap. I have no idea how the control signals will work over that long of a distance, as these things only work on 5 volts. If the voltage drop is too much across that long of a distance you may be able to use some kind of level converter closer to the carb to make it work properly, or maybe just run the pot to the boom, and leave the servo tester on the platform, it may work because they work off the changing resistance values and you just may get enough swing even with the added resistance of the extra long wires, or just run thicker wire to limit the resistance drop. Another idea is to also just use a 12v solenoid to push the plunger in and out, but that would limit the choke to only 2 settings, say half choke and no choke. it defiantly would be nice to have confidence in being able to start the motor from the platform no matter how long you are up there, in any conditions. Good Luck.
Struggling or not your videos are appreciated. Of course, I will watch if you take on the boom disassembly job, but that is a heck of a job. You're really do a terrific job of explaining things in a way that is easy to understand. Thank you for all your hard work making videos and sharing them with all of us.
in regards to the boom lift repair you talked about I would like to remember what they told us in music appreciation class: "if it's not Baroque, don't fix it".
I've been watching Farm Craft for six months. This is the first time I have seen him do farm-stuff.
As usual, your video is rife with opportunity to crack wise and be otherwise crass, tacky and/or crude... but I'm going to pass this time. Instead, I'll simply say, "Job well done!" Whittling away at one problem after the next and not stopping until you have results or at least answers.
John, I suspect it's your TENACITY that inspires me as much as your total combined skill set. And like all of the good farmers that I've known in the last 59 years, you are most certainly a jack of all trades and a master of none, but still better always than a master of one! And because of your videos, there are at least 361k people out there with a much higher respect for the craft of farming!
KUDOS!
I would be in the "if it ain't broke, don't fix it" camp.
But that's just me; on something that large!
However, I'd love to see the project cause I know you can do it!
Ever since I was a six-year-old snot-nosed kid... we never owned anything prior to that time... I took apart everything in sight... so yea... go for it... it's how you.... and us... learn.
Can't wait to see that event...
So cool to meet the girls. They look pretty happy. You are obviously the kind of humane person who knows how to treat and love the animals who give their all for you.
Also, as a person who has spent most of his life as an amateur mechanic messing with old cars (the kind with carburetors) I have concluded that carburetors are the ultimate mechanical curse (even worse than the Chevrolet Vega). We of mechanical inclination should say a daily prayer of thanks to the deity of machines for mass production of fuel injection. BTW, your trouble shooting skills are top notch. Well done.
You will regret it likely but there is peace of mind when operating machines like this...but we will enjoy it!
If anyone can sort that boom out it’s definitely you . I for one would love to see you tackle it , love your videos 💪👍👍👍
I know the engine starting problem was the video. But I never get tired of the cows new grazing pasture!
Great improvement! Such equipment often doesn't have an ideal fuel tank and fuel line positioning. If there are long runs of the fuel line, especially large diameter line, it can leak back into the tank causing a lot of cranking to re-fill the fuel lines. Shortening, repositioning, or using a check valve can help with the initial cold starts.
It’s not the struggling that I enjoy watching, as much as the success you achieve… eventually!
Cheers from Tokyo!
On automotive automatic choke carbs, it also has a choke pulloff mechanism, which this seems to lack… on cold start, the choke (if set) is completely closed, but as you start cranking and it fires the first time, manifold vacuum is created, which triggers the choke to be partially “pulled off” (barely cracked open) by the choke pulloff. And then it slowly opens the rest of the way as the bimetallic spring warms up. Imo that is a good starting point on how to handle the choke: keep it fully closed until the first cough, then crack it open. But you’ll start to get a better idea what the engine wants as you use the thing.
This is your answer. This is what I recommended in your previous video as well. This is spot on.
Your perseverance is what I enjoy not the struggles.
I love how you treat the cows. Big Mama is a star😁
That mini roll of tape is genius!
I'm a retired US Navy F/A-18 combat pilot who can drop a bomb through your chimney from over 10,000 feet and now an airline pilot who can land so smoothly some passengers don't even know we've touched down and so I watch FarmCraft to remind myself just what a dumbass I truly am. REALLY enjoy your channel, always a thumbs up.
Whaaat? Hahaha. Dumbass? I think not!
@@FarmCraft101 Oh yes! If my life depended on being able to do what you do, from making canons to rebuilding engines, they may as well take me out back and shoot me. Keep doing what you do and your channel will have over a million subscribers I'm sure. One of the best, johnson jokes notwithstanding.
Not here to see the struggle but i do enjoy the learning experience and the resourcefulness
John,
Glad to see you've finally tamed the beast. No charge.
Please take the boom apart. That would be an awesome video. I have faith in you John!
Great video! As for the chain, unless there is something about it that feels concerning when operating it, I would leave it alone. If you feel like it moves gritty, too much resistance, inconsistent, or anything along those lines, yes, a proper inspection and maintenance is worthwhile. If its performance doesn't show any sign of concern, it's probably not worth the effort.
You know that in UA-cam land, content is king. The chain is a major project that has not been in a UA-cam video as of yet. His problem finding skills will make a video interesting to watch.
I'm not a mechanic by no means. But I work on my equipment. Sometimes I get into things that I'm not familiar with and need a little help. When I get into something that I don't know much about people like you help me get it fixed. And sometimes your viewers help also. You have a great channel and great people-watching. Keep putting out the videos I enjoy watching them. God bless you and your family and your viewer's brother.
My god...the mini roll of tape...this made my day. Going right into my camera bag rightnow. This works with graffers tap too.
Noticed that the more you struggle the more people watch your channel and judging by the comments everyone is just waiting for a new video to drop....do the chains and the huge cilender...that will be amazing to see.
The fact this thing ran as well as it did before you replaced all the half-bad\bad components is actually really impressive.
I’m so happy for you!
What a freaking nightmare.. I hate intermittent problems too
congratulations
I don't enjoy watching other's struggles and tribulations, but I certainly enjoy when you're successful and I'm always praying your efforts don't need to be great!
Since you are always going to run the engine without choke, and only choke it for a few seconds when starting cold, I'd add a return spring for the choke lever on the carb. side to make sure it won't accidentally go into choke while you are on the lift-basket.
I am getting to know your farm pretty well. I saw the scar from the monster tree. I saw your fields and the pond. I saw your porch and fireplace. It's getting to be like "Disneyland for Adventure". [I know you got the money to repair the Nissan. I am glad we could be part of that.] Carry on good sir!
Am I going to regret that (taking the boom apart) you say - I think it may be more of a regret if you don't and the thing fails on a job - with you up in the clouds. Anyway, it is just such fun watching fix things. Go for it. 😁
stalling engines are par of the course for this channel - the more you play with your Johnson the better you get at it ;)
Now why do I get the impression you aren't talking about the outboard motor manufacturer? ;P
If we never hopped on the struggle-bus, what fun would life be? Your living right!
Very enjoyable content as usual, if you decide to tackle the boom chains please please please get someone to help you with it. That is too big of a job for one person and the risk of injury would be high, love the videos all the best from the UK.
The last drone video got me thinking it would be fun to sit up there and call in some coyotes!
Go for it John, besides when you get that done you’re pretty much have a new bucket lift. Then only thing left is a new paint job
ed here, bought oldtrex 40 footer when retired to trim my trees with. had lots [fun] working on it. it was diesel with a remote wire/box and boom control. the izuzu diesel ran perfect wit new glowplugs to start. once i was up high/ lost control, manage to get down even when all oil blew out main up/down cyclinder. lost barrel oil down boom-fun was getting the 20/40 extension cyclinder out to rebuild! after trimming/ downing several trees decided lift was too complicated-dangerous-old, sold it for twice what i gave $2500. it had too many old hoses to worry about blowing out! requires ace mechanic to work/ make safe-not me.
I'm sure of you want to repair 10 cars for your community, your subscribers will support you. Your content is awesome.
I love all of your work. You are an excellent mechanic and very inspiring. I really hope you don't do the boom. I was a Crane operator for 35 years. I've seen many pieces of equipment repaired and I've also seen these mobile booms repaired. That is a very big job that requires some specialty equipment in my opinion. Great work great videos.
"This is great. I can choke it and play with it while I figure out what it wants."
As these things usually turn out, yes, you should take that on, you will regret that, but in the end you'll be glad you did it.
It's not the struggle as much as the way you apply the process of elimination to resolve the problem. You are a smart and practical man and you have a great common sense approach to accomplishing the mission. That's why I watch your vids.
You got it with the boom , it's just parts ,and you have the equipment to get it done.
Your videos make me feel better that I'm not the only one struggling with vehicles and machines!!
It might be a editing artifact, but it seems to me that the limpy cow's leg seems to kinda "snap" right at the ankle when she is puting all the weight in it, right at about 17:24, might be worth for you to take a closer look at it
Woah...that does look like the ankle is favoured...and when weight is applied...pops straight. (Makes me shiver a bit...as I have a similar ankle! :) )
My dad was a chevy man. His thoughts for sure, BOAT ANCHOR, put a chevy engine in it so you can go to work. Maybe? Great work trying to keep a ford running.
I think you’ve already decided for yourself that you ARE going to do the chains. Otherwise it will gnaw at you until you do it! 😂 And I don’t think you’ll struggle with it- you are very resourceful and experienced. Great video as always!
I adhere to the old saying, “if it ain’t broke don’t fix it”. However I honestly would enjoy seeing you struggle over tearing the boom apart 😁. You have a talent that unfortunately I do not have. But I hope by watching your videos that my brain might retain at least 1% of what I learn from you. Who knows, some day something I learn from your vids might save my butt one of these days🤷♂️. Also love the intermittent breakaway to the cows!
One experience I had from my old days working on engines is that when something is hard to start check your fuel pump pressure assuming you have a mechanical fuel pump. If there is a slight opening in the diaphragm the fuel runs back to the gas tank. The vehicle will run but it's hard starting because it doesn't have the fuel available right away to the carburetor. So if you have a mechanical fuel pump check the pressure.
*- Wow, what a neat trick...the Electrical Tape Mini-Roll.*
Wow that’s awesome that some people caught that arcing in the video!! Good eye.
What I like is the perseverance through the struggle. My favorite person on UA-cam by far.
Lets do it... We will supervise from afar! You got this!!
You should do it. You're going to struggle but in the end you'll be glad you did. Also, it will give a lot of people to learn.
Since you're already in the swing of fixing things you might aswell do the chains and whatever else may need attention, rather than wait for the inevitable failure at the most inconvenient time/place possible. Thanks for taking the time to bring us along and explain things along the way, keep it up.
Great idea, looking forward to the future videos. Thank you for your efforts, I really enjoy watching them.
Thanks for all your work and as a non farmer i do love the cow breaks, used to visit my uncle Marts farm in pa and shifted hay and helped calve, as a kid it wasnt work it was fun stinky fun
Hi there, I really enjoy your channel and all the videos you put out. I am diy fanatic myself but not into all the heavy gear you work on. But it is always enyouble to see skilled people like yourself troubleshooting different problems. Gives me both a good time by the computer and input on how to solve my own problems. Keep up the good work and I wish you a great weekend all the way from Sweden.
Great work! Always educational and entertaining content. Thank for sharing with us!
Having seen the multitude of damaged, scored and rusty hydraulic rams which Kurtis on Cutting Edge Engineering (Australia) is presented with, it is imperative you inspect the ram, cylinder, hoses and chains. Wouldn't matter so much if it was a ground based machine - you'd run it 'til it failed; but this is a real safety issue - you're 60 feet up in the air and even with 'fail safe' you're not going to 'feel' safe. It's a life thing so go to it - and I'm sure going to enjoy the ride! All the best, Bill B (UK).
Happy to see you stuck with it and ultimately got it all fixed up. What a satisfying result!
I had a 93 Nissan Sentra that started giving me all sorts of engine running problems. I finally figured out that you could pull the codes using the dash lights and when I did that it showed the Engine Temperature Coolant Sensor was bad and the wires had corroded. After I replaced it and repaired the corroded wires and connector it ran great. Rainman Ray Click!
Yes and yes, can't wait to see you rebuild that boom.
Your persistence paid off again!
Keep them coming John awesome work 😅 you do .
The saga of this lift has been one of my favourite stories of the last year. I'm from a UK farming family (sold up now, blame Brexit) and spent some time as a kid (back in the 1980s) in the workshop making mechanical problems worse whilst our fitter rolled his eyes, swore extravagantly and eventually grudgingly nudged me in the correct direction (most often laughing at how a brainiac like me could be so stupid). Thanks for bringing us your problems and solutions. Now live in Whistler, BC - not much farming around here.
Great video and great work with the engine. Its nice to follow how your cows are doing!
Great vid! Watching you troubleshoot that engine is very entertaining, and enlightening.
Great mini-roll trick! Love it and will use it!!
You will absolutely regret pulling that boom apart... Do it! I wanna watch 😀
I am convinced that some of the older methods are hard to beat. Good job young man.
I watch your videos ever week. Always learn something. Thanks for including the short vignettes about the cows.
I have thoroughly enjoyed these episodes of the lift and love watching your channel thanks so much!
I have been binge watching your videos, and I love pretty much everything you post, forgot to hit subscribe after finishing up the series on this lift but thankfully it immediately got recommended to me!
Subscribed a month or two ago because of the interesting content, staying because of the great content and goofy editing inserts. Keep up the great work!
