Love your videos. Beautiful farm and family. So many can learn from your demeanor and how well you handle adversity. Thanks for sharing
Murphy's Law in full effect. Paint color doesn't matter, they all break eventually. Can't wait to see it put back together. Thanks for posting this stuff, learn a lot from your videos.
We never broke an axle on any of our tractors. Just doing hay sure couldn't have caused that. It had to be cracked previously, and finally gave up.
Si c est possible de casser un axe d essieu arrière en roulant en ligne droite: j ai connu un cas similaire sur un tracteur d une autre marque.
Par contre, dans cette vidéo, la cause de la panne est double à mon avis:
1. Des jumelés avec des montes de pneus tres ou trop larges.
2. Un mauvais conducteur qui "tourne" trop court avec des pneus jumelés, ce qui cause une force de rippage démesurée sur un seul essieu arrière.
En clair, lorsque l on met des pneus jumelés sur un tracteur, on apprend d abord à conduire en apprenant un minimum de physique des forces avant de se plaindre ensuite. Ca evite de passer pour une bille.
Thanks for the video. I used to machine these 8000 series diff cases, IVT transmission housings, transmission rear covers, and some of the Camoplast parts for the tracked versions before moving into a CNC maintenance tech. position. It's cool to see how some of the components are installed on the case as I only dealt with the raw casting. One thing I can say about Deere was they had pretty decent castings and would scrap anything showing signs of porosity on the outside of the casting or any critical areas such as bolt holes, bearing surfaces, etc.
I work for a tier one Deere supplier. When this happened, it is around the time we had a rash of Deere axles breaking. They require us to get our forgings from certified suppliers. They blamed us for not ultrasound testing the forgings. It ended up being that the forging supplier changed the "recipe" of the steel . After a big "pissing " match. they finally agreed to the source of the problem. It cost our company $500,000 to prove to Deere that the forgings were the problem. The ultimate cause was cost cutting, and short cuts in the forging process.
I do watch a lot of your videos. I try to watch them all! I truly wish, Andy, I was half as smart as you! There is nothing you can't do and no one works harder than you! Thank you for the videos!
It aired up pretty good (the tire) when I was a farmhand we had to change and rotate our on tires,the 20x8x38 Rice&Canes was the hardest but we had all long axles with duals. And they would buy in bulk sometimes up to 12 tires at a time,if we changed out tires(it was cheater buying so many at a time ). And we used a Slam Hammer and we would have probably 2/3 tractors at a time down changing tires. Enjoyed watching !
I really love the tubeless stems, came in real handy on all my equipment in 2021, went through too many tires to keep buying tubes. At $750 a tire for my 4630 and having to replace all 4 rear ones I didn't want to spend more on tubes.
Love the sign language 😂 And nice looking boots on you and Jered.
Thanks for the ride along Andy, a little bit of everything in this Video, sign language, tire repair and a heavy lift on the final drive.
Although I think that I would have used some straps and shackles with that loader to move that drive assembly, not worth getting a hernia, back issue or smashing a foot.
I know im asking randomly but does anyone know a trick to log back into an instagram account..?
I somehow lost my account password. I would appreciate any assistance you can give me.
@Ira Ralph Instablaster :)
@Major Jason i really appreciate your reply. I got to the site thru google and I'm in the hacking process atm.
Seems to take quite some time so I will reply here later when my account password hopefully is recovered.
@Major Jason It worked and I now got access to my account again. Im so happy:D
Thank you so much, you saved my ass !
@Ira Ralph glad I could help :D
I liked that pneumatic tire bead breaker, using a 10-pound sledge is kinda "hit & miss" (good-upload)
God bless you Sir, you are a great example of what a Man, one who has learned to rely on himself and when a job needs to be done, well just get it done. Don't look to blame someone else for your troubles. Just do it and go on to the next Job.
Because if it doesn't get done it cost you.
Hope full harvest and get top dollar for the sales price this year Sir 👍
Andy I will say one thing that after I watched you take the axle off I bet that the hired help ain't gonna mess with the boss lol I enjoyed the video as usual the real world as a farming operation and again you handle it in stride thanks for sharing
Today on Farming Fixing and Fabricating: Farming, fixing, and hernia surgery.
man need to get on some atlas stones and show Brian shaw how its done
I always had bad experiences running johndeere while merging,was using a 7810 and it had many problems and was too gutless for the job
So I swapped tractors and put a case 7140 on the merger and its been amazing ever since,I love the 7140
Good
My boss rented the 7330 out to pull a merger a couple years ago.
They got over into Missouri and couldn't control it on the hills, needed something heavier.
It is so good to see mechanics able to use low tech methods. It is important to keep using basic manual repair techniques.
Gee Andy that axle looks like it’s been cracked for a while 1/2way through,( that dark half moon shape)
I definitely don't envy y'all that job. I dealt with something of the sort once, but at least the axle was still in one piece and the hub remained in place - rim locks on an Allis-Chalmers 170 broke. Smaller machine and wheel, but all we had was a little 2-ton bottle jack (dad was in the phase where he was still learning "buy cheap? buy twice") and, various pry bars and wrenches, and dad's and my brawn.
Thanks for saying you'll be putting the axle back on in a later video. I'll be watching it for sure. Thanks Andy
Well at least it broke in the field not going down the road
I was surprise how many different jobs you have to know I will add you and start to follow look forward to the next video 🤟😷from the UK 🇬🇧
Get you some lift straps and use the wheel loader, may have to wrap the straps around several times. Can be a bit tricky but doable and much easier on your back. Cheers :)
Man that’s crazy, good thing it wasn’t going down the road.. iv had a few broken axle shafts on trucks and tractors but it’s usually someone’s fault lol. Good video Andy Take it easy
I couldn't imagine how mad my dad would be at me, if that happened while I was using it 😂 .... yea I actually can imagine it
It wasn't the fault of operator. Have you gone back to school yet?
Well at least this time you guys didn't tear off the whole trumpet housing and all lol. Thanks for the video Andy, have a good one.
Thanks Scott
God bless Gerry farmers thanks for all your hard work
Looks like a fatigue fracture in an induction hardened axel. The ring around the outside is the induction layer. If you look closely at the dark part of the fracture you may see "Beach marks" due to intermittent crack growth. This type of fracture requires cyclic loading, maybe a bent axel. The induction hardening puts about 100,000 psi compressive stress on the surface, the axel can't crack until applied stress exceeds compressive stress however the surface layer is subject to damage - deep scratch or wear groove & excess heat are common causes.
Great video Andy! that field repair was not an easy one. I was curious what the tire pressure was and you answered that. I cannot believe one wheel weight is 450lbs! I recognize that sign language too LOL. Thanks for taking us along with your day to day stuff brother. Cheers
You are welcome
Always interesting to see your videos. Always doing something different. Thanks & I appreciate it.
as an old machinist if you look there is a large dark scallop in the axel the was a flaw in the original steel they cut the axel from seen it many times in logging skidders and many other machines brian from washington state
I hate seeing breakdowns like that sorry for the bad luck buddy hope you can get it fixed as cheap as possible God bless
YOU ARE one strong MAN. LIKE THE POSITIVE DEMENTER. God bless Farmers.
Whatever breaks, just stay calm and fix it. Good work, and also reminds me of the 8320 that totalled , still hurts me a bit.
You picked a fine time to.leave me loose wheel
Dude that is a very very cool tool for breaking tire beads off rim 👏👏👏👏
Years ago we owned a case 500. All orange in color. We were making irrigation ditches and the ditches took too big a bite and stopped the tractor dead in the tracks and the axle broke. I was young but it seemed bigger around. Well we ordered a new axle. Three months later it came. It had stickers from all over the world. It went to Japan and the to England and Germany. Postal service
Says “alright you ready?”
Stands over the top and gives the other person no room to help lift.... 😂😂🤷🏻♂️
He meant ready to be away from the dropping heavy part. Why have someone else help you lift/move, if you can do it by yourself and possibly hurt yourself.
He was talking to himself :)
You guys are good at Farming, Fixing & Fabricating but even better at breaking stuff. I grew up with 6 brothers, and we were pretty hard on equipment, but not even close to the stuff that happens to you guys. Maybe in the 60's, 70's 80's John Deere made better equipment.
All their 8020's have well over 10 000 hrs if I remember right so I wouldn't call it completely unacceptable
Long hours you are going to get problems
Bro I’ve never done this without a crane. That was AWESOME!!!
That sucks, going to be a costly repair. At least the Dealership going to help you get it installed.I like them new shoes you guys have on. Andy you're going to sleep good tonight after this day ends 😴 That tool does an excellent job!! Great vid as always 👌 catchya and the next one. Be safe!!
Why would they its not new its called sh#$ happens we just deal with it and go on nothing sucks worse then breaking down but just like concrete is guaranteed to crack tractors are guaranteed to break
No John Deere won't pay
@@jwhitley101whitleyfarms9 ok I get your point!!
@@FarmingFixingFabricating Good thing he wasn't traveling down the highway when it snapped!!
I got a hernia just watching this video.
Hey it makes for a good juicy video ,but you can tell from 12 to15 feet away and a thousand miles to me ,that the axle was fractured. You can clearly see the tell tale dark shadow one third to one half of the way through progressidly. It didn't just fall of due to a thick stem of hay!!! Observations by a journeyman motor vehicle and heavy duty diesel mechanic as well as a journey man Weldor fabricator . Worked at Deere and Cat dealerships as well as farming thanks, nice video none the less!!!!! Well prepped!!!
Hate to see that happen!! We bought an 8120 brand new back in 04. Put close to 12,500 hard hours on it feeding cattle and pulling a vac planter for years. Probably one of the most reliable tractors we ever owned!
Never a dull moment on that farm that's for sure!
Hello -- I Grew up farming too -- Time -- Starts 2 hr`s before the Sun and when the Dog stops following you supper time or when you hear the sleigh bells Mom rang to get in here Ah the good ol days LOL SUBBED You .
That sure is CLEAN off! So neat cut..
Andy, get a JRB jib boom to go on your loader quick coupler.
Respect ...great skills great Job
Espcially field fixes
Great video. Sure is interesting when stuff happens on the farm like an axle ripping off.
Looks like a good rig to turn into a pullin tractor now💪 lol!! Nice when ya got all the tools to work on a problem like that 👍👍
Good thing you know how to fix it, what an unexpected pain
Yes
Glad you found out the apparent cause of the broken axle to be someone before your time using a cutting torch to remove a bearing. That created a weak point in the tempered axle which is damaged from the excessive heat. Hope that becomes a Deere bulletin to all Deere mechanics at least for future reference.
Cutting a bearing off wouldn't have caused that to break, if the bearing was out and it got hot maybe
@@RJ1999x they cut the axle when cutting the bearing off. You can see the notch at the bottom of the axle when he shows it inside the wheel. You can also see that the break face is smooth around that point and more rough on the top half, indicating a fatigue crack emanating from the lower point on the axle, most likely caused by the stress concentration caused by the cut.
@@j.e.honiball1327 doubtful, possible, but doubtful
@@RJ1999x I wasn't speculating, that is a textbook stress concentration fatigue failure, I know because I have the textbook right here.
@@j.e.honiball1327 lol! Seems odd that the axle had no overbuild in it, that a nick from a torch would cause it to fail, but then again it's a John Deere so it's very possible
How come the senior man is doing all of the bull work? That was crazy when you were holding that heavy part until the kid was finally out of the way. With all the equipment that you have, I was expecting to see you break out some slings and attach them to the bucket loader to pull the final drive off with. It was amazing that no one got hurt. Best wishes to all. Subscribed. : )
Thanks
can`t stop watching your interesting videos
Glad to hear that
Framing Fixing & Fabricating , Andy, please be careful trying to handle parts like that! I just crossed the 15 year anniversary of me blowing 3 discs out on my lower back! I was replacing Intercoolers on a large Marine Diesel Main Engine. A 16-645-E2 EMD (think a really big Detroit) (645 Ci per cyl x 16 cylinders) 3000 hp that might have weighed 200 pounds. Hell, I used to pick them up by my self but this time there were three men on it when one of them lost his footing and caused him to fall down. I caught all the weight to stop it from crushing his legs, I never even had a second to think about it, it was something anyone of us would do. This caused my to have to have back surgery and ended a 30 year career as a Chief Engineer. I live in pain to this day but I know that anyone of us would have done the same thing if in the same situation! When something happens, there is NO time to thing "What might happen", you just react. When I saw you take the weight when that broke free, I had flash backs to when I did my back in, you only get one back, please try (I know it's hard and I'm sure years of abusing my back doing things like this didn't help) to be careful and remember, the make chain falls for a good reason!
Thanks
The dark spot in that axle is where it first started failing. It starts as a small crack and then when it stressed it will crack a little more, then a little more. It creates beach marks, or semi circle rings that originate from the initial crack. That small flaw will continue to grow until its big enough to cause a sudden failure. I can see the faint signs of the beach marks and it looks like the failure originated from inside the axle core but hard to tell from the video.
You are corret. Cypris made the axle forgings to Deere specs. As a tier 1 vendor, we were requirerd to get forgings from Cypris. However, Deere slipped on the inspection of the metalurgy. When the first axle broke there was a lot of finger pointing. Deere blamed us for not ultrasounding the forgings, but they wouldn't pay for the additional work.
You made the tire work look easy
Andy thanks for videos. Sorry about the equipment break down . Only positive is that I feel better knowing it doesn't just happen to me . And you are great at explaining things . Adult beverages galore on that break down . 👍🍺🍺🇺🇸 Just hit the subscription button.
Thanks for subbing
After selling you the tractor, ... JD says "yeah, that model did that ....."
You guys wreck more equipment than anyone else I've ever known of!
Oh
Not Much luck with the 8020's ehh? Nice video Andy keep up the great work!
We always used a smaller tyre on the outside wheel of a dual set-up, to reduce the bending stress on the axle.
Smaller tire will wear out real quick, you need to run same size tire
Smaller tyre or less pressure outsides,more sensitive driving on rough surfaces a.s.o.Thank you.
Another great video big boy, had a little bit of everything in it.
Like watching farmers fix things.
you are a mad man Andy lol ... watch out for your back, don't take much to put yourself out of commission for a few weeks...
I've seen and heard of quite a few deere axles breaking over the years
Man those thorogood boots are the best boot a man can get. Hell mine are like slippers
They are indeed, appreciate them
I like how you got the tires and axle off of the large John Deere tractor and had to get the axle replaced. The way you took the tire off to replace the valve stem was nice also and the tire bead breaker works nicely also and must have been a great help in the shop. I hope you all got the machine back running without too much down time and the work was completed in the field.
Yes all back together
@@FarmingFixingFabricating That is great.
That power suit the military is working on for the soldiers would come in handy right about now. Geter done.
Excellent video well done top job top team awesome thanks
The shit never ends, for problems! Lol!
I can relate to your issues for sure!
“This is not an OSHA approved blow gun.” That is why it works.
RAM mounts makes the mount. You can order directly from them.
Yes I have several of their mounts
Apologize to jr., as I thought in the other video that the wheel axle dropped off while he was merging.
Thanks for letting us see the preparation for the fix.
Blowgun has air coming out, OSHA approved does not..
Harry in Ireland watch your back Andy
New viewer from Cambridgeshire in the UK love your filming very interesting look forward to following you in the future
Glad to hear
Corb Lund wrote a song about this guy! Hard on equipment look it up fits this guy to a tee !
We ain't hard on equipment
Andy showing that “dad strength” lol just tossing that shit right off. Don’t screw your back up tho
I use a JCB backhoe Rear arm, and with toothed bucket level with the top the tyre to break the beads. Never fails even on high ply count tyres.
John Deere the deere-est piece of equipment any farmer owns! :D
What we used to do was put blocks under the tyre and let the weight of the rim help seal the bead again
Great video Andy
Oh no chevy makes John Deere now .?!?!😂😂😂😂
Time to call in the 4620 💪Ol Smokey 😝
7:22 hope for him that knock sound wasn't the diff's bevel gear falling in the transmission case!
The axle has been stressed sometime, if u look at the break pattern u can see the start of the break it did not break all at once.
Just subscribed to your channel. I enjoy watching the repairs done in the field and also like to see the comparison of the “at the shop” repair or continuation of a field repair. Do you have any hired help with the farm or is it all family? And, if possible, could you mention in a non-specific way, how much some of these parts/repairs cost ?Such as,” this part costs in the neighborhood of $--.00 . If possible. Without tears as I’m sure maybe you don’t want to remind yourself of it. I just love American farmers, nothing seems to get them to give up. Give in, at times, maybe, but not give up ! Great videos, thanks.
Both hired and farm employees and I usually discuss costs
On the farm had a dual rear axle chopper wagon break both axles while loaded. The road crew brought over a pay loader to pick it up and the fire department brought air bags to lift it up so the guys could get it high enough to fix.
I like his helper just kicked the planetary with his filthy boot. Forget contamination.
It all cleaned up no worries
judging by the dark color in the center of the broken axle I would say it has been cracked for a while, Looks like it could be a common problem with the wheels extending so far out, It might be a good idea to dye checked the axles on the off season or when the brakes are being done.
Yeah it was and it was from a torch weakening the steel
Seen it happen on a Jd 9430. Work for les schwab went out today and put hubs and wheels back on after it got axel replaced
inflate it the cool way .. starting fluid and a match boom inflated ive done it it really works !!
OLF has a great secret of sealing beads, the light and run method lol
That's not dot approved
You could have used starting fluid to air up the tire. Have an extinguisher handy! That metal seemed a tad heavy? Great video Andy
Need to get a lifting reach attachment for your loader. Makes it a lot safer to take stuff like that apart in the field.
Could’ve just took the telehandler
Keep up the awesome videos Andy!!
A set of forks on the Rubber Tire Loader. Would have made the disassembly part a lot easier. Great video Thanks
Did a similar job in Iraq 2003. Welded a chain half link to the final housing (green bell looking thing) and broke axle. Then just hooked a chain up. Pulled out with the loader. No effort at all.
Might be time to switch to the Red Tractors. Unless you like working on em!! :) Keep up the great videos!!
This is true, I have never seen a green tractor 🚜. Massey Ferguson is the #1 in fields around the world, for durability and reliability you get a MF.
@@europaeuropa1858 lol he meant case ih but I like all colors
Reminds me of a controlled chaos kind of day on the farm! Stay safe!
The dark area on the axle has been cracked for a while, looks like it's been broke about 50% for some time. Looks like it twisted the other half off as a bounce should look like a clean break.
Great video!!
