John Deere S790 - How to repair the clean grain and unload system after harvesting down corn.

Here we got a trade in John Deere S790 combine that I inspected. Came up with a list of things to fix, but the clean grain and unload system took a pounding from running in down corn last harvest. Lots of dirt ran through this machine and wore down the augers badly. In this video I will show you how to repair the loading auger, clean grain elevator chain and sprockets, vertical auger, and horizontal unloading augers. Stick around for the next video as it's going to take more than one video to finish this monster. #johndeere #johndeerecombine

This helped me a ton..first time working on a combine they put me on, replacing the top shaft. Unfortunately service advisor didn't really have much info on replacing this. This video helped me a ton. Other than that mine didn't come apart as nicely as this one did 😂. But I still got it done in half a day.

[@donalddehaven3229]

It’s always interesting to watch how each piece of equipment you work on is different and I can understand how it takes years to be come a master tech. Great channel

[@DonMajicJuan82]

Doing this job right now and just can’t pull that hard to lift that chain over the sprocket but love watching all these jobs. We have a 670 and they give me a little insight before tackling the jobs. Thanks for everything. I’m also in Illinois about 10-15 miles north of Danville.

[@oolaisaac9967]

awesome you open my mind every time i watch your videos I keep learning. Keep the green iron moving

[@jacklisiecki2389]

Thanks Zeth. Valuable lesson learned about root balls and the action of dirt on augers.

[@frasermathers2287]

Zeth, loved how you keep it so real. Things like the Mag Parts tray falling and you tripping over show how simple things go wrong even for well skilled techs. We have all been there and some times these things are just a nuisance and other times they have far worse consequences, but every time we learn something from them that make us better! Thanks as always from Scotland.

[@georgeduncan5332]

Appreciate the time you put in to making these videos. Thanks.

[@stevenicoson6670]

Thanks for another great video ZK. This one was most interesting b Well, I do not know what to say. This video was a tremendous learning experience. Wow. Just never realized how much you had to take apart and dismantle to do this job. Sorry, I feel pretty uneducated with some of this work up in the grain tank. I have great respect for you and Josh for tackling this job. Wow. The hot weather does not help the situation. Considering all that you working against I feel you are doing great with a difficult repair job. This video was a great educational experience for me and I am sure others. Thanks for filming this and talking us through this situation. I am totally exhausted and I was just watching-ha. My hat is off to both of you doing a very hard job and dealing with the heat. You both take care and be safe. Looking forward to the next video. Thanks for everything ZK and Josh. The Iowa farm boy.

[@donalddoty2543]

Real good video on repairing augers. We have on our farm rebuilt many augers, on other brands. One thing bothered me was not wearing good protective gloves, and maybe long sleeves when lifting them out. Yes you mentioned the edges are shape. Those augers can slip, rotate and major cuts can happen. Thanks for the information on how a low hour machine can be worn that much.

[@arzamumma1202]

Viewed 7-18-22 from Fairview Hts, Ill. Yep........dirt in combine is job security. Grain mixed with soil will just eat up anything it comes in contact, this an example of MAJOR WEAR. Must be very careful the auger flighting can become razor sharp and cut you to pieces.....wear good gloves. Again an excellent video :)

[@jimclary7309]

Zeth enjoy setting back watching your videos it's a learning experience. I appreciate sharing your knowledge and skills you made repairs so easy. Keep the action coming catchya at the next one. Be safe!!

Thanks for sharing your time and experience. Really helps us DIY types.

[@christopherschneider3323]

I'll have to keep in mind that bearing trick. I've always just unbolted them on both sides then I can usually pound the shaft in enough to either cut the bearing or air hammer it off with a curved chisel bit. Then pull the shaft towards me to remove the spacers and sprocket and I can pull the shaft with the other bearing out as one piece. It works but I'll try that way next (Pretty much every other machine needs it done)

[@williamosullivan5920]

Good morning mate. thanks again for another awesome learning video. hard work being a John Deere AG tech with that heat in the shed bro

[@BRPFan]

Another awesome video! Them augurs get so sharp you could shave you face with them! Here in Manitoba we see that from bean combines. Keep up the good work Zeth!

[@adamtebrugge4937]

I find quite often that the bearing bores in the aluminum case are damaged, and then it is cheaper to install a new gearcase, rather than rebuild the existing one. Keep up the great videos.

[@ZKMasterTech]

I can rebuild it way cheaper than replacing the complete gear case.

[@gregorythomas333]

The before & after of the sprocket was like WOW!

[@Adam_Poirier]

Looks like you started off the video already at sweat level seven, I've heard it's been a hot summer for you guys in your area. We've been semi-fortunate here in the Northeast it has not been terrible although this week coming looks like it's going to be pretty hot. Nice work Zeth Awesome video

[@JOHNDEERE-X9]

Hello Zeth. I love JD and of course your videos. It’s a big joy for me to watch you repairing in a professional way. There is something I wonder about JD Brand. Is it true that JD produces every part by itself,from top to the bottom. Expect for the tyres and Turbo Charger. Thanks.

[@ZKMasterTech]

Thank you very much! And to answer your question, no there are lots of things Deere doesn’t make themselves.

I went back to the older style driver with 4 teeth and it minimized my issues i have with the tank auger HXE109643 mother deere told me a auger was 500 dollars this driver is cheaper as well. Give it a shot

[@davidberger4726]

Idea --- You should make some tarps of different sizes with magnets on to catch all parts and tools. Maybe some smaller platforms to hold things. Just a thought.

[@jamesbreault5762]

Great job guys👍👍👍👍👍

You need to improve the lifter into Mark 2 version - more adjustment for vertical and a caster base for rolling it out when holding the gearcase. Perhaps a vertical jack.

[@floriandiederichsen6597]

Quick questions: if the augers are worn like that aren‘t their housings shot, too? Is this normal wear and tear? Not very maintenance friendly if this has to be done every couple years.

[@nicolasgiasson2449]

great video as usual. as a automotive mechanic, i wonder how much time it take to do an inspection on a combine.?

[@ZKMasterTech]

We get 9 hours but no matter how long it takes you get 100% efficiency because usually I've got drive time and it's usually parked in the back of the shed and won't start. I usually get them done in a ten hour day but then it takes me a couple hours to do the estimate.

[@tobiasjacobsen_dk]

Boss: “zeth the S790 for you today” Zeth: “is it a easy one?” Boss: “get the bandana out son!” DANGER ⚠️ !!! 😂

[@ZKMasterTech]

Yup lol 😂 it shouldn't need much, it's a low hour combine

[@BruceBergman]

Add some graphite to the header and spread it on the downed corn?

[@kylekuntz5302]

I guess I could have waited until the next video covering a 9 series tractor, but do you guys ever do bearings to prolong engine life and can t even be done in frame? Sitting at 7,800 hrs on a 2007 9320. It runs great, injectors and cups, water pump and front dampener at 6,900 hrs.

[@ZKMasterTech]

Send in an oil sample and see what the results are. Then you can make a better decision because doing an over haul is very expensive and you probably can't get the parts right now possibly.

[@jjhanson8205]

Time stamp of 5:42 how dare you cheat on your beloved Milwaukee tools and use that snap on impact hahaha. Whatever it takes to get the job done. Once again another great video keep that green iron moving.

Hey it's not my impact it was Josh's Matco lol

Did the new auger strut go in upside down? Or does it actually matter?

[@matthofer5463]

Just a stupid question here lots of guys tighten the lock collar the same way as shaft rotation. Wats the difrents?

[@mauricebrosseau9181]

Wow, thought the green colour was the farming way to go.

[@timnichols9015]

Lock collar tightens WITH the direction of shaft rotation. Not too tight…. The inner bearing race will break if too tight.

^^ This. Lock collar always goes the same direction as rotation

Good job Zeth I like how you guys work together Now I know what to look for I am buying a used 770

[@johnbidwell2725]

You almost need a tool tray that hangs from the ceiling for the grain tank.

[@markdice2500]

Following the tool and bolt fall (06:17), more bolts, pins, and pliers were waiting and ready to cascade down into the chasm surrounding the gear box. The practice of placing hardware on flat surfaces above big holes in combines is something I would do...certainly not you guys?

[@Ollie603]

Count how many flat surfaces there are in a grain tank doofus

[@rickk6447]

I’m not sure where those xtra bolts came from, they started spitting them out the auger.LOL

[@alviney5138]

It seems the combines you work on and recondition are very worn yet not very many hours on them -- should a customer expect "major' or "many" repairs at just 1000, 1200 or 1500 separator hours /// is is just the nature of the beast that they take a lot of maintenance ??? maybe a profile of how the unit (combine or even tractor) was used (abused??) and the number of hours on it just as you start into your white board repair list ????

[@ZKMasterTech]

The combines around here get a lot of bushels ran through them. We have very good yields around here. At a 1,000-1,500 hrs you can expect to do some expensive maintenance. There are also a lot of things, like certain chains that we replace every year and there are certain things we do preventative maintenance on at certain hour ranges.

[@stevebrekken2547]

Seams like a lot of worn out parts for a fairly new machine.

[@ZKMasterTech]

Yeah it was ran hard and put away wet.

[@frank.s74]

@@ZKMasterTech Wow, for me as a German the amount of wear and tear is unbelievable, i mean this Machine isn't 5 Years old, is it? And this farmers new X9, which is over a Million $ i think, looks the same in 5 Years? He must have have made quite big Money with Corn to compensate for this. How would you estimate the wear per area and year between corn and grain?
