I don't think I've ever seen so much work carried out on one machine. This thing should be like new when she leaves your shop. Thanks for taking us on the journey. These informational videos should be used as apprentice training aids. Great channel, please keep the knowledge flowing.👍

I don't think I'll ever get tired of watching you work.

I'm just amazed the amount of work on this unit!! Almost looks like the owner hasn't done much maintenance! I would hate to see the bottom line on parts and labor. However, I have enjoyed the process to make the repairs. Thanks ZK

You know I don't have a clue of what you do with farm machinery, but it is a real pleasure watching you do it. Keep up your great work for us to watch.

Viewed 4-2-22 from down state Illinois near St. Louis. Hi Zeth, I will have to say your workmanship is first class TOP NOTCH !! Any JD farmer sees your work would want only your hands on their machine and know the work was done correctly !!!

Your videos should be mandatory watching for the John Deere design team. Your imagination and talent are second to none for navigating the obstacles in repairing these colossal machines.

He's the Bob Ross of tractor repair. so relaxing!

I really enjoyed watching what all is involved in these combines. It’s amazing to watch you pull it all apart and put it back together and look, no parts left over. Truly a master tech. If it were possible, now that I’m retired, I’d love to spend a day with you and hand you tools just to be there

Your videos are so helpful. You explain everything to help us farmers to do things correctly with less pinched fingers and hurt tempers

When we brought equiment to the workshop in my days a proper cleansing was mandatory. Man what a dirty mess you must work in. Beautiful video!

Wow! Talk about a complex piece of equipment. ZK, I like your method of writing everything down on a checklist. Logical and makes a lot of sense. Thanks for a very detailed video.

Thanks for another absolutely great video. It was most interesting and was a wonderful teaching tool. Wow. Wow. I never had seen a combine torn that far down in the business end of things. You had to accomplish a lot of Big steps to get at the swing arms and bolts. I found what you went thru ever so interesting. Taught me a bunch. You are a excellent teacher and show each step in sequence. So important. Great content in this video. Never realized how much had to be removed to do the job. Probably one of the better videos on this machine getting overhauled. Heartfelt thanks for taking us along on the repairs. So, so interesting this was. Interesting to see the inside of the combine. Learned a lot. Special thanks to you ZK. You taught me a lot on this one. All for now. The Iowa farm boy. Steve.

You show exactly what an agricultural engineer has to know and be able to not only understand what and how all farm machines are for but how they should work. Also if they do not work what to do to ensure that they do work in the future. The agricultural engineer has to know electrics, transmissions all types and sizes, hydraulics and not forgetting the engine etc. then all of the equipment combines, tractors, ploughs, spraying etc etc. was a filed engineer for IH years ago and in the field away from the shop on your own the farmer relayed on you and you alone to be Mr fix it, and his go-for man. You show this in your vids so well I think that young people out there would be waiting at your door for an apprenticeship. Your attitude is spot on to be an ambassador to the trade. From a 71 year old ex Agric engineer you have my vote. Fantastic videos keep them coming. Thank you.

Amazing idea on the modified pliers, will be trying that out thanks.

Always a pleasure to watch your videos! You deliver great content.

Gonna change all the swing arms on our 4 machines and watched this video a couple times, thanks for the video,makes it a lots easier seeing how the pros do it!Once you work one these things yourself it is actually pretty easy what seemed difficult inn the past.

And this is why Zeth is called a Master Tech! Nice job! Keep these great vids turning! 👍

Very nice work Zeth, you really earn your pay. I would have thought JD would have had a procedure of sorts for dealing with those sieve frame seals but you found a way to make it work.

Just finished this job on a 670. Wish I could have watched this first would have made life easier. thanks for the post.

Not tired of watching at all. Love it. Steve. Wheat farmer in New Zealand

Dog I don't even know jack about farming but I've still been watching these. Idk why

Excellent video guys . Very professional and informative.

Great content as always zeth. The owners of these massive machines has no clue what you put yourself through repairing these machines. They'll know when they receive bill. Lol!! Enjoy watching your videos. Keep the knowledge coming. Definitely look you up at the next one. Stay safe!!

This man’s knowledge of the mechanics of these machines is impressive.

Very good educational video, a vibration can cause alot of headaches !!!!

Wow, that was a ton of work! Very informative too!! Keep it up!

Yet another awesome video Zeth! Thank-You Sir!

Wanted to say thank you very much for ur videos cause if it weren’t for people like u videotaping jobs I wouldn’t have learned and been able to do a lot of my own work that would have cost thousands of dollars that I don’t have. Thank you sir

Love your videos, Zeth! Keep posting. I watch every second of every video you post. Thanks for your content!

Dang ZK, it's gonna be a new machine!! $$$$$ Great work! Jim.

Awesome vid! Great job!

Another great video, thank you!

Awesome professionalism.

Enjoyed this video, thank you. Regards George

well done on a tough job , i like the special tools and wish i had some of them as i always work alone and its rough work .

Great awesome video zeth . Wish sloans was up in Canada . I would certainly be interested in working there if there up here

ZK. You put a full enema on that combin to get in where you needed to go to make the needed repairs. It was great to see you setting those shaker arm rubber bushing in their neutral position through the timing sequence. Please take care. I am looking forward to seeing the next green iron challenge. 👍😎

Not tired. More please.

Always enjoy seeing both good and bad design on incredibly complex machines. Odd to use rivets on what seems to be a consumable seal.

Awesome videos. Really well put together and informative. Love watching you guys work. Just one question . Do you leave some of the dirt and grit in the machine on purpose? Would be very interesting to know why you don't blow everything clean. I'm sure there's a good explanation for it. Anyway, keep up the great work. My favorite channel to watch.

Wow. A lot of work. I’d say buy a new one but this is probably a lot more cost effective and it might be a year before you get a new one. I’m surprise you are able to get parts, but what a great job you’re doing.

Looks like a Milwaukee M18 rivet gun may be in your future........ I think I'll be doing this project on our S770 this winter. I have not changed the swingarms yet and they still have green paint on them with 1200 separator hours now but probably 1300 by the end of the year. Thanks for the videos.

I understand if it’s a field breakdown ur going to have trash and dirt everywhere but a off season repair sure be nice for ur service tech to clean up and out ur equipment

Amigo Matt, como siempre muy buen video.... Te sigo y cordiales desde el Valle del Yaqui, Sonora, Mexico.

You can pull the chopper frame out of the combine. That's the way I've done the last couple s680 combines.

Great vid !

Love the content. The bill on this is going to be scary!!!

hey mate just subscribe to your channel I really like your attention to detail when you do your repairs mate from Australia 🇦🇺

Great job seith

Very nice!!

I’ll stick to fixing new Holland combines … seem to be quicker, less panels to remove and more straight forward to repair . But super interested on the Deere technicians ways and Deere ways of design . Great video!

Those frames are a real pain Right up the....... If you put it in the deep freeze it will be easier to put it back! Seriously though, good luck with reassembly. Nice video. Good job.

How is your back? Who is kidding who here...muscle work galore! Add a thought on what this work does for the end product: A more "efficient" operating machine uses less energy (saving fuel) plus it produces more product, less lost product (money out the back!) and most importantly--a lower chance of the unit breaking down in the field...lost time and higher repair costs....less profit for the farmer! As to your helper, assistant, back up guy, #2: work him harder, make him smarter...what a team! Who do I need to speak to in order for you two wrenches getting more money? Love your work and your commitment to excellence!

It is funny, I am watching some other channels talking about how farmers can't work on their own tractors. I am still split on the issue, I was an aviation mechanic and just owning it was not license to repair there, until they came along with "experimental" class and as long as you were not charging to fly people you can do your own work. Well that killed the small aircraft mechanic field and major airlines hire dozens of "workers" that work under a real mechanic's license... Yeah, I don't like the results. Sure these are on the ground, but they are still big, heavy, powerful machines and the tech is so advanced... I don't have the answers. Just ranting. LOL Good video.

I enjoy You doing all this work. But this job is getting expensive

The ViceGripGarage of John Deere tractors.

I just had one bolt break and one bolt pull thru on my lower shaker tray today. F me. Deere tech will be here next week to pull both trays out and replace the lower one.

PEOPLE JUST DON'T KNOW WHAT THE FARMER GOSE THRU GETTING FOOD TO THE TABLE. THEN TRUCK DRIVER GOT TO HAUL IT. CONGRATULATIONS ON U ALL TALENTED &THE KNOW HOW.

Zeth, when you remove the upper pre-Chaffer, usually we install plastic finger grates on the back of the pre-cleaner. Small grain machines are built this way from the factory. Question: how much vibration or movement due you get on the tension idler of the shoe drive belt after messing with the shoe? They always vibrate some while running, just wondering. Thanks

how many shop hours did it take to change the swing arms?

Looks like real fun there I'll let you have it Lol

With the amount of work being done to this machine, I would love to know what the final bill would be.

the torq for the arms is the same for 9770 sts combine?

Do you recommend removing the chaffer pre cleaner on the S780 combines too? Will it change how the chaffer sidehill kit mounts in there?

Tools: Employee vs Employer question. You raised an interesting point that I'm not sure many entering the industry thinks about up front. In your position where you do shop and service calls. Who is responsible for tools? It is my understanding that techs are responsible for their own tools (with the exception of specialty tools) for their role. Example: A strictly field service tech has the truck loaded with their tools. A dealer tech is responsible for their tools and storage. What is expected of a tech that does both? Can you speak towards how Sloan handles that, vs say the industry average?

I’m curious..is what you’re doing just part of routine maintenance? Holy cow it’s a lot of work! How long, in real time, did it take you to pull out that chaffer frame? Seems like the engineers have no understanding what mechanics go through…you’d think JD would send a team occasionally to watch, take notes, ask questions..to see it the real world. Great video Zeth, keep up the good work!

What brand is that rivet gun/ tool

23:00 to 31:37 That segment needs to be sent to JD. Actually they need the unedited version.

Just one question, why not use a vacuum cleaner or airline to clean all the old corn and debris off the sieves etc?

Hey zk quick question. For those swing arms to replace them do you have to pull the seive frame out to get a couple of the bolts ?

You should get sloans to carry Andy clean soap

Muito top😊

I don't even want to see the final bill.it is huge.i am enjoying the repairs on the combine.

When ever I do swing arms I leave the chopper on and pull everything out just fine

Can both frames be pulled together as a set? Probably not was curious if it would make it easier?

Wrapping up this job on my s670. The video is really helpful, so thanks. After install of the sieve and chaffer frames, its apparent that the rear end of both frames favors the left side of the machine. The gap between the sieve frame and the sidewall is probably 1/2" and on the right hand side is about 1/4". There is no steel to steel contact and the seal wear marks show that it was wearing this way before. Do you have any recommendations for straightening out? Or do we just let it be? Thanks man.

they are going to have anew combine when you're finished.

Muito bom

I saw a guy weld a socket cut in half into a hydraulic hose for those tensioners

🏋️👈GENIUS i love jhon DEERE 😃💪

Can we get a total of hours and parts cost but chance on these repairs? I am very curious at the hours alone on this project.

If your back goes out, I think you should consider cardiac catheterization and angiography. Just had my 31st anniversary with my back, stay strong and work safely.

Hello friend. congratulations for your videos. everyone is great. in your video you have the tools to remove the sieve boxes. Can't you send me pictures so I can try to make an identical one?

Its 20 years since I pulled the sieves and grain pans out of MF combines, doesn't seem to have got any easier on a JD!!!!!! Least you're working in a clean shop with concrete floor instead of the corner of a field with the sun beating down and the farmer wanting to get going!!!

Where does John Deere make combines? I’d love to see them invite you to a factory tour. And you could take us along of course

Getting ready to do this tomorrow on my S790 mid season at 900 sep hours. Kinda disappointed in that...as far as all of the maintenance comments, there's not much maintenance that can be done on these cleaning shoes, what you just watched in this video is the maintenance..

Why replace the whole arms and not just the bushings? We run 2 older claas machines and boy have I had to press in and out alot of those. Its interessting that you pointed out to centre the bushing movement before thightening. It makes so much sense but I have never thought about it that way, and frankly Im annoyed🤣. Oh and we had those chaffer frames crack and tear out and man it gets all chewed up real quick

Great video but I have to disagree with not replacing the bearings on the cross shaft. Those bearings have X amount of hours on them while everything thing else has 0 hours. Alot of farmers have found out the hard way. A few more dollars is a drop in the bucket compared to the damage that can undo everything you just did. Like I said earlier, great video.

is this still the same machine that had metal shavings through the hydraulic system ???

you should design the Zek sieve corncob removal tool 5,000. Shove the sieve frame in....and here I thought it was being installed by highly experienced, formally educated professionals. Just shove it in there buddy!! And then stab that chaffer frame in there!!! Mail all the removed raised chaffers back to the corporate engineering dept. Maybe after the first 100 they'll get the hint and issue Mfg recall, so the customer doesn't have to pay the labor for bad engineering.

Only thing this machine is going to need after all this work is new pistons and a leather drivers seat!

I'm surprised the combine is so dirty.

Question. My s670 broke the rubber bushing out of shaker arm where it is driven by the Pittman arm. I pulled that arm and pressed in a new rubber bushing bc there’s no availability on shaker arms. Since then, I have broken the bolt that the Pittman arm connects to twice. The first Time I blamed reassembly error. Second time was more thorough. It breaks after about an hour. Do you have to detorque and re torque everything in sequence if you pull off one arm? Any thoughts on what could be causing it to break? In the process of pulling the chaffer and sieve now.

😍🤭😍

Scares me to think of what this "service" has cost the customer. At the end of the day, service is cheap compared to having a vehicle have a major break down in the middle of harvest season.

when a deer come for repair i have to find my only one 15 mm wrench between tons of 13 mm and 17 mm :D:D:D.. Just use them 17 mm if 13 mm can not hold :D:D and make my life easy :D cheers from europe. You doing great job

Only 500 easy steps!

I'm really impressed with your work. But I'm not impressed with John Deere's engineering in many cases. After watching many of your videos, I'm seeing equipment that requires maintenance too frequently and equipment that is not designed to be easily maintained.

Hi. For the uninitiated non-farmers like me would it be possible to very briefly give a short explanation of how the equipment work? Thanks.

It looks like a Part of a Tree inside after you pulled out the Siv Frame! The Owner should of Torched that Poor Engendered POS! Sorry but I used to work on Equipment that was Assembled Upside Down so I feel your Engendered Nightmare!
