John Deere S680 Rotor Variable Drive & Reel Pump rebuild.

[@donalddehaven3229]

I’m always impressed with how easy you make it look. I’d love to spend a day with you just to hand you tools and help. What an experience that would be for a 65 year old guy who enjoys the iron. Love the channel and I really liked the opening on you video

[@ZKMasterTech]

Thanks Donald! You might be my number 1 fan!

[@rypkepaulusma]

@@ZKMasterTech I think folks are lining up 👍🏻

[@stanleyroberts2461]

Thanks for filming it especially for us non farmers!

[@paulbush7095]

Very cool repair and rebuild video Z! Viewers have an opportunity to appreciate the amount time and money our farmers spend to purchase and maintain the amazing equipment they operate. We are indebted to the hard working farmers and skilled tech services that you and Josh provide in order to keep our stores stocked with the variety of food that we are fortunate to have.

[@Chris-r3r]

It's nice to have help I never got that luxury when I worked on combines

[@wildedog3967]

The time lapse makes you look like a maniacal mechanic on a mission . Keep up the good work fellas .

[@garyshaw3937]

The forks were absorbing your love taps!

[@BruceBergman]

Farmer note : Air over hydraulic jack for the shop press.😉

[@chrisgossman6512]

This video went through so many levels of difficulties my head is spinning. So for me I think if I put in a like 👍 all should be good. Thanks for sharing.

[@ericmcrae7758]

You are a great teacher Zeth - Josh is learning fast it makes a great team.

[@DougsHomestead]

Josh is a keeper! Slim guy that can get in holes and is not afraid to work. Has good mechanical skills to boot!

[@terrybenson3632]

Hi Zeth. Always enjoy your videos. Thanks for taking the time to make these, and thanks to Sloan's for allowing you to film these as well.. I'm a TORO & DEERE golf equipment Tech, so I really enjoy seeing your BIG iron repair episodes. Thank you again.. Have a great week..🏁🏁

[@ZKMasterTech]

Thank you!

[@jacklisiecki2389]

Thanks for an informative video, Zeth. I don't think I've ever seen a splined shaft seized that thoroughly! Great job.

[@Noahs80series]

I love the fact that you two are alwasy laughing and enjoying the job no matter how much of a pain it can be sometimes Support all the way from New Zealand!

[@timnichols9015]

Who else replayed 24:46 MULTIPLE TIMES? Epic. Enjoy the content! Learn some, laugh some!

[@jonarmedpiandsecurityoffic9051]

Must have been very happy to meet him

[@arzamumma1202]

Viewed 8-13-22 from Illinois A lot of work, but you and Josh completed the mission !

[@mauricebrosseau9181]

Watched your video for the first time. Love it, enjoy your explanation of what you do. Being raised on a small grain farm I can relate what you do. Harvest being my favourite time of the year. Farmers down there are lucky to have someone with your knowledge.

[@doughuffman5790]

Glad to see the hot oil bearing installation. I had a stupid supervisor USN CPO that loved his hammer on $50K NT3 18” bearings. I criticized and was ordered to do it my way, with an oil bath.

[@aaronbecker847]

One rule about working on combines - it is always 20 degrees hotter than anywhere else…

[@samrugtiv3839]

You two are a good team.thanks for the video.

[@stevenicoson6670]

Thanks for another great video ZK and Josh. It was interesting and enjoyable as always. Well, you two technicians made a big job look easy. Tough area to get into but with the proper steps the job is easier to contend with. Appreciate all the do’s and Don’ts you showed us. Sure helps understand the job. You two are the best. Don’t know if I would tackle it but after watching it done might try with some knowledgeable assistance. As always, thanks for your excellent teaching skills. Much appreciated. About it for now. Thanks to you and Josh. You both take care and be safe. Looking forward to the next video. Thanks for everything. The Iowa farm boy. Steve.

[@johnbucklerfarms]

Looks like Josh is Working well I just hope he Stays! I was Director of Maintenance and after Hours of training People they left for better Jobs! I was Disabled 7 years ago but it’s my knees after seven operations no kneeling so no Service to equipment! I love watching you guys work!

[@harpreetsingh6819]

Hi. Josh you make every work very interesting to learn. Best way to explain and do the things..👍👍 I am from INDIA.

[@alffred4021]

Gute Arbeit, ihr seit gute Mechaniker 👍🇨🇭

[@timhewitt8894]

We have found that a small dab of silicone sealant at the end of each wire in the sieve and chaffer stops vibration and makes them last much longer

[@codyeftink7403]

I've replaced several of those rear channels with chaffer in. It's not much fun. Have to fish outside bolts in with a magnet but it is possible. Did not know about the washer spacing on the springs. Will definitely be checking them from now on.

[@lastguy8613]

Your man Josh seems to have a real good attitude and work ethic, I hope he goes well

[@frasermathers2287]

Hi Zeth, great video as always. I always believe in keeping your equipment well lubricated, but when you pulled on that pipe, am sure that was a little too much lube :) . Getting that shaft to come out of the drive was a tough one, but as usual you made sure you and Josh were the winners. Thanks as always from Scotland

[@jameslopez407]

Might I suggest some foam like an old or new couch cushion for your knees in those tight spots. Great Job you guys!

[@randybreuer1685]

You almost make me miss our old 4400 combine

[@michaelbuxton9368]

What a project.. good work!!

[@chrisbrown9999]

It's a good looking combine

[@glennrhinehart3186]

Best channel on KZbin

[@ZKMasterTech]

Thank you!

[@farmahedvikaslatinky]

Opět TOP práce. WELL DONE Mastertech ! God bless.

[@steveanderson2095]

Hey Zeth. You and Jose should have a big deck umbrella set up when working in the sun like that. Well done. You should visit New Zealand sometime. Steve. Wheat farmer. New Zealand

[@rickk6447]

ZK, Love your videos first of all. Just brainstorming right now and a thought popped in my head. The problem grain dust, has John Deere ever thought about putting a blower in the hopes to help get the dust out of grain? I know the combine does really well, but I'm referring to all the dust that eventually gets to the bins and dryers. Just a thought, I know the number one destruction of Grain Elevators used to be explosions and fires, that has changed a lot over the years. But there's always xtra dust that always ends up in trucks, wagons, and eventually in Grain Bins. It's just another value item that could help withe increasing Sales, through value. It's called Value Selling for most Sales people, no, its not that John Deere needs more sales, but I'm betting it sure would! Keep up the Great Video's, I'm trying to get a job with John Deere, not so much as a Master Tech, but as a person that can help wherever I'm needed. Any idea's? If so I'd love to know. Let me know if ya do below. I wouldn't want ya to give names here so if ya know of someone I'll figure out a way to contact ya. Thanks and keep up the Great Video's, we Love them.

[@dln11]

Another good job Zeth! Keep up the great work!

[@garyriggins3354]

Wow ,that goes to show preventive maintenance does work.

[@TheVespap200e]

Nice job guys. That was quite the project! 👍

[@ollie-lk5dx]

That looks like extremely fun job ! I didn't even hear any working words lol You must be good at editing.

[@jean-marieberton1348]

Hello from France I did the same operation and by removing the panels and its support as well as the tension pulley of the auger belt it is easier to remove the variator from the rotor

[@gregorythomas333]

Well damn...I guess everything is now super-well lubricated!

[@brianfreitas4794]

You guys are awsome! Aloha from hawaii!

[@yougotmossed3592]

Just excellent videos!!!

[@genechronister7085]

Great vid! Very informative and interesting vid!

[@marcusjames3814]

zk my friend marvelous as always man

[@Ham68229]

Why aren't those splines anti-seized from the factory? Bad seals/O-rings won't matter, the anti-seize will remain on those splines. Air hammer works better than a hammer on some of those stuck shafts. Awesome video. Cheers :)

[@robertbarker3110]

What a job! Great!

[@BRPFan]

Great video Guys!

[@davidwulf288]

Would hate the bill on this one. lol. Awsome seeing what makes these things do what they do.

[@kywd51]

I roughly came up with about 6K in that shaft and those sheaves.

[@davidkraft3690]

Wondering how many hours or years on that combine ? You sure keep them running.

[@2007dalin]

holy shit.. glad i don't need to run john deere equipment lol.. just changing a belt looks like something you would never bother doing for maintenance

[@timjorden8329]

Another big job well done

[@kanyonwashburn1782]

Love the videos. The audio is high pitch since you switch to the new camera.

[@jest2927]

ud es una persona inteligente por usar el sistema metrico decimal,es decir,milimetros en vez de lo atrasado de las pulgadas

[@conradpaul58]

Had combine going in 4 hours to fix seperator drive and rebuild it with 6 guys

[@dmruemw]

Love these videos

[@Harvest9650]

Thanks for the video, ZK. I'm what you call a "custom cutter" here in Australia, also doing a lot of repairs and maintenance to farmers combines as a sideline business. This machine looks like an earlier series (judging by the chaffer and sieve) and I'm wondering how many sep hrs are on it?

[@ShainAndrews]

Like pulling a 454 from a Volkswagen on jack stands one story tall.

[@smitty9733]

I have a 67 year old massey ferguson that is built like a tank. It has been rebuilt 3 times but will last another 50 years if maintained. These new machines are awesome but very very fragile in my opinion.

[@ZKMasterTech]

This combine has moved more grain in the last 5 years than your 67 year old massy has done in its lifetime.

[@jamesbreault5762]

Great job men👍👍👍👍👍👍👍

[@davidkimmel4216]

Thank You 😊

[@stevetrowbridge7101]

Did ever John Deere dealer have old press like the one you were using?

[@BruceBergman]

Does the Farm assault vehicle have a lift gate for the tool cart? tommy gate or similar? For heavy equipment.

[@robertpeters9438]

I wonder if an all electric drive combine would make service easier.

[@BruceBergman]

Factory needs Antiseize on the manufacturing linr for the splines

[@smokken10]

In all steel things I use beef tallow, why do you use greas and oil ?

[@petereriksson1390]

When use a 3 mm washer should give you 46 to 47 mm, thats spot on! If you got low 42 to 43 mm, must been the steel get thats thinner over time, time to change, part of the frame😊 if it's the result!? From Peter Eriksson Sweden Europe 😊😅😊!

[@michaelburton5760]

good job men

[@floriandiederichsen6597]

Stupid question: why does the shim change compression length of the springs if you torque them down the same? Is the bolt bottoming out? If so, you can use your usual torque wrench…

[@donaldberg7955]

Always enjoy and learn from your videos....On a Typical JD combine, what would be the estimate of total gallons of hydraulic oil in the machine!! Always impressed with the engineering and manufacturing technology.

[@ZKMasterTech]

Around 50 gallons

[@matta3888]

What is the rebuild cost compared to new hydraulic drive you rebuilt.

[@chrisbrown9999]

I think we've had everything possible off of one

[@marine2ful]

If they don’t put overhead cranes in the shop, can the company at least some 7.5k crane body truck for you guys?

[@stevetrowbridge7101]

I still thing the best combines was the 95 and 105 Texas farmer be safe.

[@agger838]

Milwaukee should make a chain winch

[@jean-marieberton4607]

Bonjour de France j'ai fais la même opération et en enlevant les panneaux et son support ainsi que la poulie de tension de la courroie de vis de vidange il est plus facile pour déposer le variateur du rotor

[@ricko3145]

Josh seems a bit rough and ready. Old saying tortuse always wins the tace

[@t63a700]

Should have brought some fire crackers for them damn birds!!

[@williamorman4779]

Workin on my gleaner you have to bleep me some.

[@35markers]

What S series would you buy?

[@ZKMasterTech]

S790!

[@davidberger4726]

when you pound shafts out, etc. you need to have it on a solid backing?? Yes --no ????

[@petereriksson1390]

Superblower = hairdryer!😊😅😊

[@kennethfeld6639]

Smoke Wrench solves everything

[@BruceBergman]

Needs a shop press.

[@waltersmith7380]

Should have used the press to take the hub and the shaft apart ,would not have ruined the shaft.

[@jameshattenbach5578]

Should have called me I have a cap that would of worked lol but I have been there and done that

[@littlesteve855]

Does the Agression Level go to 11?

[@ZKMasterTech]

😂 it never ends...

[@jamesbreault5762]

Don't forget the pressure washer

[@1topfueldrag]

that screen could be better designed to eliminate or reduce wear on rods. Use a different metal

[@ms-mac521]

👍👍👍

[@CRice-ln8lm]

Zeth, you might not believe this story, but it is true. I noticed right before this point kzbin.info/www/bejne/ZmGqdp2tgJ52jbc that you used the heel of your hand as a deadblow hammer and it worked well. I had two friends that did this on a regular basis. Over time, both damaged the nerve center that is about where the lines in your hand approach the wrist. One lost the feeling and use of his arm and hand to the elbow and the other ended up in therapy trying to get use of his hand back. You cannot afford to have this happen to you. You have tools better suited to thump on stuff.

[@danielhiller9165]

why not plastic?

[@randydehne8866]

Zeth. who makes that t bar puller.

[@ZKMasterTech]

Not sure. Been in our tool room forever

[@randydehne8866]

If you ever see a name on it. Let us know.

[@ukaszklein6836]

😉👍

[@alliagrochannel2511]

How i contact with you brother

[@infinite97]

300F is way too hot for any bearing mfg. I’ve ever worked with. SKF recommends 110c, timken suggests no higher than 250F. Why are you going so hot?

[@ZKMasterTech]

Deere recommends 300

[@perfecttimeforadventure8126]

I’ve got a five hundred ton press

[@markjurkovich7814]

And this is what happens when you don't do your MAINTENANCE!

[@fyrman9092]

Man, there's no room to work.

[@marshalllarson8970]

The adjustable pulley's are not shives. It is spelled sheaves so pronounce it like the eaves of a house with an sh on it!

[@ZKMasterTech]

@marshalllarson8979 Then Google sheave how do you pronounce it. There’s multiple sources that says it’s pronounced “shiv”. From Wikipedia: A sheave (pronounced "shiv") is a wheel or roller with a groove along its edge for holding a belt, rope or cable. When hung between two supports with a belt, rope or cable, one or more sheaves make up a pulley. The words sheave and pulley are sometimes used interchangeably.
