Major separator damage! Removing a rotor out of a John Deere S770 combine.
Вставка
- Опубліковано 30 гру 2022
- After a ripper shank ran through this machine, we are going to remove the rotor and inspect for further damage. This is a HUGE project and is something we do not get to do very often. For the most part, these combines are pretty tough, but not ripper shank tough lol. It takes a serious amount of damage to have to pull the rotor to fix everything it tore up. This is one of the projects that happened this fall but got put on the back burner until we had time to fix it right. In this video, you will see Josh and I take everything out of the separator and inspect for further damage that we could not see with the rotor still in the machine. It's going to be a fun adventure!

Can’t even imagine taking all that stuff apart much less putting it all back
Truly amazing master mechanics 👍🏼
I once worked with a mechanic that found 11 grease fitting out of 55 on a truck . Hate for him to be working for you and trying to maintain a Green machine! Unbelievable seeing the guts of that monster.
I just recently found your channel, I’m speechless. Very impressive and informative. Let’s go back to the 70 & 80’s equipment, lol
Imagine the sound coming off of that thing as it RUD'ed! Must have been heart wrenching!
All I can say is .... I'm glad I don't have to write the check to pay for this ... that shank turned into one expensive piece of scrap steel!! The damage is just never ending it seems. Great Video as always thanks for bringing us along!
those combines are half scrap to start with..lol watching these repairs on them makes me realize how terrible the designs are.
@@2007dalin especially if you go with case lmao. This season (australia) I worked in a Case 2166, and we broke down no less than 30 times. I would often have to manually turn the rotor over to clear, even in light crop with a high concave.
If that Case is breaking down that many times or any combine for that matter then no one is prepping the machine in the off season. A friend has an 88 series and runs 2400 acres a year through it. It has 7600 hours on it. I run 450 acres through a 1400 series this year. Pull the belts and roll shafts over to check for rough bearings, etc. Separator bushing and bearings should be changed every 900- 1000 hours.
If it's a newer Deere and not in warranty it's not worth writing the check. Much better alternative brands out there - some doing things Deere is behind.
@@sodbusterone yeah that was the issue. It’s my cousins farm and he has gone a bit off the bend so to speak, he has some (some is an understatement) mental issues and basically left the machines in the paddock, I.e: the drill is still in the field to this day from April. We ran 7000 acres on 1.5 machines (the other combine’s shaker fell apart so we only got half a season out of it). It was a hell of a dodgy job.
Anymore damage and that thing would surely be a total loss. It’s incredible to see how much engineering goes into these things. Great video guys. Sloan is definitely getting their money’s worth with employees like you. Thank you for taking the time to produce this video especially after all of that hard labor!
Not necessarily. It's a relatively new unit and probably reasonably low on hours so still worth it to repair it. We had damage on one of our 790's in the 5-6 figure range and insurance still wants to repair it while a 90's era 4wd with 4-5 figure damage is being written off simply because of its hours and age.
@@joshuadoll9000 I forgot how much these things cost. Thanks Josh!
@@joshuadoll9000 I'd shell out the 4-5 figures myself to keep that 90s era 4wd going, no computers or Democrat mandated EPA emissions BS on that baby. The kid who rented our place after dad and I retired spends more time fiddling with computers in the cab and chasing electronic gremlins in his new green machines than he does farming. They had some big new 200+ HP Deere out there this spring, (I don't know the numbers anymore I haven't kept track since the 7000 ten and 8000 ten series) trying to plant beans and something went wrong with the computer and the Deere techs spent all afternoon out there under the hood trying to get it to run. I told the kid if he had an old 4955 instead of that new computerized plastic POS he would have been planting all afternoon. LOL
@@trevorn9381 We ended up buying it back in the mid-high 5 figure range because it has a PTO which we need since it's our cart tractor and PTO 4WD tractors are tough to find in our area and it's also our snow plowing tractor and if we bought a new one we'd have to buy a whole new blade as the blade we have is set up for the frame of the tractor and isn't compatible with any old tractor.
Was there any chips in the gearbox bottom?
Astonishing!! Since I was a kid I always wanted to know how this things work, what's inside and all of that. This is like a dream come true, and I thank you guys for that.
Simply awesome!
That was an amazing video. The engineering that goes into a combine staggers the imagination. It's also amazing that men like ZK Master Tech are able to repair these incredibly complicated machines. 👍
That must have made a hell of a racket when it went through! So much damage. Must have been a very expensive repair
I bet it did!
Hope he had insurance
@@agger838 $8.00 corn is the insurance.
@@robertreznik9330 but I bet he had no profit left.
You don’t farm for profit, you farm because you enjoy it
I have had to fix a lot of things on the farm, but I am sure happy I never had to tackle this project. And by the way, thank god there are men who can fix something like this. This is a show for Mike Rowe on Dirty Jobs.
Amazing video, thank you! Cool to be able to see inside such a machine in this detail. Incredible how densely packed the components are in there. And even using the special tool it obviously takes a lot of skill to remove that rotor without doing a lot more damage. Or losing an arm.
"That's a lot of damage!" -- Flex Tape guy
OH MY!!!!
That makes me hurt, just looking at the massive damage to the rotor and accompanying components!!
I'm sooooo glad you were able to save her, and not just put down at a salvage!!
As fewer and fewer new combines are built each year, we need each and every one, as they are a vital link in the human and animal food chain!!!
God bless you too!
he looks like he should be some super tuff Biker type, but that guy melts my heart! Very soft, kind and knows his stuff! Great videos
Absolutely incredible how intricate these machines are. Lot of hard work but at least you guys got to be in the nice warm shop which I'm sure was a nice trade.
That had to have made a racket! I'm guessing that the operator's seat cover needs to be replaced as well.
I recall plenty of Case/IH rotors when I worked in Osage IA. I don't recall seeing this much carnage on any of them. Great job!
I totally agree
Very cool to see the process of removing the rotor and other parts.
We bought a lease return CaseIH 8240 and are doing an end to end rebuild. I was telling the boys that maybe green paint would reward our efforts better, but after seeing how complex the Deere is, oooh man. We can get from feeder house removal to rotor out in, maybe a day, two guys. Ihle has all the Hardox rebuilds and liners. I've been waiting for someone to do a video on a Deere tear down. Thank you and Happy New Year
Real good video Zeth! Never seen a rotor and surrounding shields removed from a S series combine! I hope the farmer had insurance cause this will be a huge workorder! We did lots of stone damage repair mostly on New Holland combines but never from a cultivator shank! That must of been very loud when that shank went through! Thanks again! 👍
Great videos to watch and seeing the nuts and bolts of a combine!!!
Awesome content . Thanks for a GREAT year of vids. Can't wait for 2023 and see what you will be working on
Happy new year!
I do this job more than i would like, especially top covers. Have never had the opportunity to bring the covers out the front.
Good to know it can be done this way. Best of luck with reassembly.
God, these jobs look really extensive, hard and time consuming. This is really next level. Hope you are paid really well for this 😅
I think this is one of your most interesting videos. Thanks and have a safe and happy new year!
Happy new year!
That is absolutely incredible that the shank didn't lock up the feed accellerator and end the nightmare with a belt smoke instead. And the rotor tines all shearing like that is quite a sight as well. I think the White Hall store nearest me had a local S780 this fall with the very same issue that required the rotor removed and massive hood damage.
Glad you filmed it...Very professional..
Incredible amount of work went into that repair. I am impressed. Thanks for sharing. My like 👍 is in. Happy subscriber 😊!
Wow just catching up on the videos always enjoy watching them y’all are awesome yea it must have been one heck of a sound going through wow!!
Wow Zeth, what a job! When you think that sometimes a big rock can just plug and bring the machine to a halt, but this ripper shank just kept going until it had its way with the rotor etc. Thanks for making a video of this as its not every day you see a rotor being taken out. The other thing that kept going through my head was when you see the damage to the rotor components, just think what would happen with a human body going in, guess you would just need a water hose for that repair! Thanks as always from Scotland and have a great 2023.
I ran a flat rock in my gleaner and it pushed the cylinder into the tailings augers over 6hrs of fabrication and some new words I was back in corn,I love your videos keep up the good work.
@@williamorman4779 How did it get past the rock door? On the old Gleaner we had if you picked up a rock it popped the door open and the rock fell out and a red light lit up on the console to alert you to stop and crawl under the combine with that tire iron looking thing that hung on the side of the clean grain elevator to close the door.
One time dad ran one of the clamps that held the Unverferth duals on our Deere 4230 tractor through the Deere 4400 combine. It fell off while we were planting corn one spring, looked all over the field for that thing but never found it. Found it several years later with the combine while cutting beans.
The pin move not letting the hing to get out of the way ,keeping pressure on the latch.
@@trevorn9381 the roll pin was to long keeping the latch from opening all the way,I repaired all the latch and the door too.
Our self propelled harvester had metal detector in place wire in earth to three-quarter million dollar combines not have metal detector
Hey there Zeth! I really enjoy your videos and insight into your repair processes! I'm a Service Manager at a JD Dealer down south but we see a lot of the same equipment. Keep up the great work! I constantly refer my guys to your videos for input and a better working knowledge of the repairs they may run into out in the fields!
Awesome!
I like watching you repair and fix John deere tractors
Holy cow! John Deere makes a rotary combine? They are on the cutting edge of development!
Great 👌👌👌😊😊😊 content. I loved learning about how a combine works I never knew that. Thank you again for the great content. You always bring. I look forward to seeing the next videos.
Thanks for another great video ZK.
It was interesting and enjoyable.
Well I must say I would be scared to death to tackle getting that rotor out. Wow and more wow.
Some big massive parts to deal with plus all the other pieces.
My compliments to you and Josh for your fine work. Lots and lots of damage here in this combine. My goodness. Never saw one beat up like this before. Massive damage for sure.
I am sure the figures on fixing this combine outweigh the overall cost of the machine. That is the first thing that crossed my mind. Wow.
Thanks so much for showing us all of this. Huge huge teaching tool on this one. Lot to learn and understand.
Heartfelt thanks to ZK and Josh for showing us the process. Glad you have that forklift tool to manage the rotor getting it out.
Looking forward to the next video that covers getting this back together.
You all take care and be safe.
Looking forward to the next video
Thanks for everything ZK. Now I know why you are a master technician.
Thanks
The Iowa farm boy.
nice video, got a few good laughs in and reminded me of some of the repairs i have done over the years. this doesnt even look bad compared to some of the combines i have seen. only thing worse then a piece of steel is boulders, , posts, header parts rolling thru. gravels wear down everything fast. eastern montana/ dakotas are known for rock farming. the older combines can eat alot of debri more so then new ones. at least you could get parts. theres some farmers stuck on there 80s combines and everything has to be bent/ welded back together or made. resurrected a few that are still going. just takes alot of creativity to take them apart and fix. find solutions for problems never thought possible. dont have to much fun. miss these machines but glad my nights of working on these is over with. lol
Now that was some carnage! That must of made a hell of a noise when that ripper shank went through! What a job! 👍
The driver didn't hear it's he must not have known how to stop it
And you’re hilarious brother! Don’t hold back! 😂
Wow , what a lot of work to fix !
Man, that is a lot of damage and requires a lot of hard work on you guys. It is impressive what you have to go through. Thanks and have a Great New Year.
Can’t imagine that bill. Wow, Happy new year!!!
Awesome video Eugene from Ontario Canada 🇨🇦
Wow what a job!
Wow. What a job!
Great video big man! Thanks!
Thank you for your awesome content 🙂 Happy New Year and keep that green iron moving, brother 💚
Happy new year!
I have replaced the left and right frame rails all the top rotor covers and multiple other parts a S680 and a 9870 john deere due to edible beans being ran throw the combine to wet and plugged the rotor. I also had to rebuild the five speed gear box on the S680. It was a long process repairing both combine but was a satisfying job to see them both running again.
dang, that rotor is big....its suprised me. Nice Vid MasterTech ! Happy and blessed new year for you and your family (incluing youtube family) From Turkiye.
I have repaired many things. Never a combine, I must say wow there is alot in there. Good stuff👍🏻👍🏻👍🏻
I think it needed more salt so the shank would taste better.
That was a tough take apart. Thank You for sharing the guts of a router. I didn’t see any smashed fingers. Great job 🎉
Loved this video and im waiting the next one.😃
Thanks for sharing wow that is some damage expensive stuff to glad I don’t have to pay that bill I seen a drive shaft underneath the cab that looks like it would be a heck of a job to repair too if it was to go out have a great new year
I was thinking the same! The universal joints don't last forever. Same with the augers under the rotor.
Great work and Happy New Year
Happy new year!
I don't know much about farm equipment to I had to look up with a ripper shank is. Wow, that's a big strong piece of metal to run through a precision machine.
Wow, major damage and work here !
Awesome video, Zeth!!.. Really cool to see the inner threshing system of these new combines!!.. It's amazing how large the rotors are in these machines.. Thank you for taking us along on this teardown.. Happy New Year!!.. 🥳🥳
Glad you enjoyed it! Happy new year!
All the best for 2023 to you, your work team and family.
that poor machine swallowed but could not quite chew properly and a chucked out mess was created.
Happy new year!
"Always time for lubrication" is your phrase. Ours is, "Everything is better with lube". Life in a mechanic shop. I love it.
That's a nightmare awesome video thanks for sharing 🚜🚜
when i was taught to cultivate row crops the farmer said to pick a landmark every so often ( electric pole, etc ) and make sure you haven't lost a shovel. if one came off you know where to go find it.
I always look forward to your repair jobs. I'm sure that was a "aw sh#$" moment for the owner. Always count your shanks when you leave the field....LOL. Happy New Year.
You made it look so easy but your description told us different. I’m always impressed with your skills. How many hours did it actually take to do just the tear down before you could start putting new parts back in? Love the channel
Hope you have a great NEW YEAR !!! Keep up the great Videos.
Happy new year!
@@ZKMasterTech non a mech. But I enjoy the vids. Do parts not like that. Be safe. Thanks for the heart. Means a lot. You and your I wish the best. Keep up the great work !
No governor, there was definitely no noise from the combine and I never heard a thing 😂
Another blinder Zeth, thank you guys for showing us this.
That’s an awesome and beautiful setup you got there
Great peek into what an ‘ag mechanic’ really has to do, day to day.
I’d suggest a slight edit to your video. Insert a still shot of a ripper shank, when you first talk about it, so your viewers can see what actually went thru the combine.
Also, the back story as to how that happened, would be interesting.
Great video as always. That's a textbook example of FUBAR.
looks fun with that angle
Those rotor covers wont go thru the side. So I took them off thru the back. But from the front it would be much easier and faster. Thank you for showing this.
Could you imagine the noise that made going through, ! Operator will have great stories to tell their grand kids. Josh mate, put some gloves on please while feeling damaged/chewed up steel brother. Keep up the good work mate from New Zealand.
Can you only imagine what the operator was thinking when he heard BANG AFTER BANG aside was going through. Great video
Absolute major props to y’all for working on these massive pieces of machinery. My brain couldn’t even begin to process how on gods green earth I would’ve even BEGAN to take that apart. I’ll happily stick to being a dodge dealership tech and stay in my lane😂
Unos maestros muy buena las erramientas que usan
What a job zeth
Happy new year Zeth and family see you in 2023
Happy new year!
Honestly I’m impressed the shank went all the way through?!!!
Probably punched a hole in a grain cart, and tore up an elevator. Currently residing in a silo waiting to continue its journey before somebody realizes it is there....
WORD bruh!!
Sort of surprised Machine is not totaled. With all The damage.
Happy new year 🎉 my friend to u and your family!!!
Happy new year!!
What the hell have been harvesting with it? Trees or what!!!! OPERATOR is key for the life of those machines.
Good job
Gotta wonder if the person who lost the shank was the same person who found the shank. Gawd, I bet that made a racket and a half.
Man that is some serious carnage glad I’m not the one cutting the cheque
Hey Zeth, awesome video, have been watching since your first videos, really appreciate the insight into your world, what ever happened to your other apprentice ? Is he still around hope everybody at sloans are doing well 👍🏻 Happy new year !
Thanks mate for another great educational video can't wait to see you put back in John Deere quality parts 👍
Не понятно, что все же попало в механизм. Отлично, что производитель обеспечивает даже такие запчасти👍
@@mmm365 thanks
Zeth I’m sure that’s the most expensive shank in history in the farmer probably has it hanging on the wall of his shop !
You should have ask him if you could borrow it for your video !!
I wonder if he considered just totaling the whole machine ?
I guess everything is reparable on a John Deere !!!!
I’m sure other people want too see that Ripper Shank !!
I hate loosing anything especially when tires are $5,000 to $10,000 apiece !
The farmer would have rather punctured a new tire. I’m sure , I feel sorry for him !
Enjoy your content, Zeth !
HAPPY NEW YEAR !
its crazy to see the parts i used to make at waupaca foundry (the stamping on the parts WF) be on the actual machine getting replaced.
Very good Video 👍👍👍
Thank you guys sure enjoyed the video
That must have made a heck of a noise when it went through the machine.
Great job repairing it.
Looks like the ripper shank did it's job. Busted things wide open. Will be good as new when done. I'm trying to figure out how it didn't punch a hole in the rotor.
That reminds me of a combine that came through our shop. Chunk of I beam about 3 feet long went all the way through. Wrecked everything including the separator gearcase and the 2 speed rotor gearbox. It was 120,000$ to fix it. And it was a tri stream rotor so all the elements and tine mounts were broken off. Extreme damage
Ouch!
@@ZKMasterTech Wow thanks for replying Zeth!! As a 3rd year ag mechanic/John Deere tech myself your videos are very helpful and entertaining. Keep up the great work
With a project this massive - How in the world do you keep track of all the nuts and bolts you remove? Do you ever put something back in place and then realize something should have gone in first? You guys are just amazing!!
You just gotta remember where they came from
Oh my every time I ZK opens his mouth I hear the register ringing
Another great job Zeth - good to see the customers are keeping you gainfully employed but I would have dearly loved to be within earshot of the interview of owner with operator ( if an owner operator he's gonna be kicking himself enough) but I don't know how something that would cause this amount of damage can be ingested from field beans!!? Lodged wheat or barley understandable if you're trying to pick up but beans don't need mud skimming eh? If the Green Machine had a maize header - again understandable as the leaf could hide a lot of sins - but then the feeder must have clanked out a scream or two - how long does this guy need to shut down?
I bet the parts list looks impressive even without your two handed labour! Looking forward to the reassembly - Happy New Year.
The u/j @ 26:50 looks handy to get at with everything still in place, assume it is accessible somehow. Bet it woke the operator up when the ripper shank went through!!!
It must have been a noisy 15 seconds to do so much damage. Love your logical way of doing things.
I see you did not bring in the comments from the introductory pictures. This looks like an exact duplicate rotor to the International Harvester Axial-Flow that came out in late 1976. As a young man just starting my career about fall of 1978, or spring of 1979 I helped to remove the IH rotor for repairs. Just from the looks i would be surprised these two manufacturers parts could not be inter changed.
Good video. You guys do great work.
Yep way back when I worked for Hendricks, agra power had a Herscher Illinois. I pulled a few rotors how they all 1600 and 1400 combines to be a lot easier than pulling it out of the John Deere.
All we need was a come a long and a table on wheels out in about 1/2 hour after the feeder house was off
fair job zeth keep up the good work. how close to the combine being a write off?
Very interesting 👍
