You’re the best Zeth! Thank you for the great content. This one really caught my attention...I’ve got a tractor with the same problems. Keep up the good work!!!!

I am not a farmer nor a mechanic. I thoroughly enjoy watching your videos. You are in depth in explaining everything step by step even I understand after you are done. Keep up the hard work

Now there's a mechanic whose worth every penny...outstanding work sir.

Bedankt voor het uitleggen

love the speed montage, great way to show steps that are small and repetitious. Definitely adds quality and time efficiency to the videos! Please add more of these speed montages!

Great repair. Your customers have a great resource with you fixing those equipment.

Of course another successful repair and another satisfied customer. Thanks for sharing Zeth, keep them coming buddy. 💪👌

I really enjoy the education. Love the channel

Great Work, love watching someone that knows what they are doing !

Great job Zeth!!!!! Keep up the great work. Thanks for sharing.☺️☺️☺️👍👍👍👍

Zeth, you rock brother!!! You are a true professional

Thankyou for a great video, never to old to learn.👍

Great instructional video, thank you for sharing!

Nice! Never have worked on farm equipment but that fan system is cool... literally and figuratively!

Awesome video! Great information. Thank you for sharing!

Excellent video, very well explained. I'm gonna watch them all.

Excellent.Detailed.A great eyeopener for those who try to stay on top of service intervals.this is a must do when time allows.Great video.lots of thought an time and care.

It sure is a lot of fun watching you guys learning a few new tricks on the trade. We wrench on John Deere and timber jack skidders every day and we're also into Milwaukee tools. Thanks Mr for the shows you're awesome 👌

Another exceptional video as always, enjoy watching your videos. It shows that you're a certified technician, you're very knowledgeable showing specific steps to get the job done. Keep the action coming, definitely look you up at the next one. Stay safe!!

Excellent Zeth really enjoy watching your videos after nearly forty years in the trade I still enjoy my work and learning all the time

Precizní práce mistře. Na to je radost pohledět . God bless !

You guys are absolute professionals. The best

I am not a farmer or mechanic, but I enjoy watching agricultural related videos. I enjoy watching the big tractors being operated and repaired. You do a great job with your videos.

phenomonal ideas. still room for improvements

Awesome site! You do great work, very professional. Be safe and take care.

Me and my son noah thank you for all your hard work

Very talented Thanks for sharing

Excellent video Zeth! Sitting here looking up my parts list now. Looks like you can get most of it ordering 3 part numbers. I do most of my own repairs that are straight forward. Your video really helps. I’ve taken my fan drive apart and greased it by hand. Got 3800 hours so far. Would be nice of Deere to provide better info to make customers aware of improvements like this. I would rather update my tractor now than have it fail in season. Thanks for pointing out the improvements and sharing.

Always good to see a yellow water pump before the old one tears out the gear train! Haha we leave them primed too. Good vid! I haven’t done that style of Vari-Cool yet. Thanks for the tips!

The naysayers have no idea about the dedicated and inventive history of John Deere. From a self cleaning plow to equipment bigger than many small houses, saving manpower with increased productivity in the field. The vision and creativity of Mr. John Deere and his Company is only just beginning. Another great video Z!

Thank you for the videos..

Another great job seth

Great job 😊😊

Informative thanks. Watching from Ontario Canada 😊

Viewed 1-21-22 from Illinois I like your work ethics..........SO important to get the job done right the first time around no re-do's !!!

Nice work man!! I work on Cat iron, it's always cool to see how different manufacturers attack similar issues or designs.

Pretty amazing. And here I feel like I've accomplished something when I change my oil!

Thanks for sharing 👍

This house painter now knows how to swap out a vari-cool fan drive. 👍🏻

Thank you. A great vid. I enjoyed that.

No glove on his right hand, and no cuts from the radiator fins. Expert at work.

This video is perfect timing. 9330 with a fan drive service long overdue.

Another great vid!

Great awesome video Zeth , time for a good upgrade I’d say , great work

Another great vid! What a beast!!!

Very nice job zeth 👍👍👍👍

Great content. Straight to the point... Thanx

I find your videos fascinating. I marvel how clean you can keep your hands ! I wonder where you get those great gloves you use so much.

Well done.

Great job...great tips...I just might be able to do ours now!!

Whatever your employer pays you zeth he is making out because you are a true professional and there lucky to have you keep your camera rolling i love watching your videos

Thank you for taking us along. That Deere makes those product improvements for older machines is a choice but in the case of factory-balanced parts I'm sure advances in technology have helped. Balancing parts is one thing but really automating it is another. Do you have an aquarium by chance? There's a fish disease called ick and I seem to recall it makes a mess like that oil leak.

Good work

Brillant mechanic top class fella videos unreal

Great video

YES. You are an engineer!!!!!

Regarding the comments you get about the engineering of the parts, engineers need field validated empirical data to refine the parts and make them better. If they had done this from the start for every part on the tractor, the price would be 10 times as high and people would complain that it was over-engineered. John Deere is doing it right. I wish my kitchen appliance manufacturers would take a page from JD on servicing older units. Great videos, BTW. I really enjoy watching skilled craftsman at work.

Wow. How am I only finding out about this channel today??? What awesome content!!! Keep it up!

Couple podcasts that I enjoy that pertain to wrenching are the Diesel Performance Podcast The Diesel Podcast. Even if your not into the performance side of things there are some good knowledge on emissions systems, fuel systems, vgt and diagnosing issues.

Great video Zeth!

Zeth, this is very informative. We have a 2011 9630 that is past 2,100 hours. It was overhauled in frame at 1,900 at Sloan's at White Hall due to a valve dropping in the head, but I'm almost sure the original fan drive is in place, and I had no idea that it would run out of lubrication in that cavity. I know we've had our tech put a 2nd water pump on it around 1,300 hrs, and it has now had what you refer to as the "rotary union" on the drive shieve put in. What I'm gathering from this video, is we need to discuss it with our tech, but definitely lean towards taking this apart just as you are doing and at least put new grease in our drive and check the shaft and bearings. I'm figuring this update is inevitable and looks like an improvement over what is there where it can be greased (we like to grease) and maybe the problem will be cured once and for all. I'm planning on keeping this tractor now that I've already had to take the hit overhauling it so soon into it's life, and the cost of new continuing to rocket up.

Very cool. I like the trade secrets you share. Myself, I would have put in a big piece of cardboard or similar after the fan was removed. It scares me that I would slip and punch a hole in the radiator. Just me. If it were not for bad luck I would have no luck at all. Thanks.

Sorry about that Zeth....great video of the replacement of that assembly, who would have thought you would see a snowmobile clutches on a tractor....It makes perfect sense for simplicity of variable speed drive for the fan...

Great step by step thank you ZK😂

Nice job sir.

Just started watching your channel and really enjoy it. Would be interesting to know how much the repair bill was for replacing the fan drive assembly and some of the other repairs on other tractors. Maybe the customer doesn't want that known but would put things into prospective what it costs to own and maintain a tractor like that.

I love it!

I'm loving these tear down/repairs. I'm reminded of my father who was an agricultural mechanic in the 1950's (WARAG in the UK). One good story he told was they were attaching a bulldozer blade and a work mate put his forefinger through the hole to see it it was aligned..... of course the blade slipped and took the top of his finger off. But the man just popped the top back on, wrapped an Elastoplast around the wound and carried on.

You are one of the better mechanics on the Tube. I was a mechanic in the 70's and 80's, but; had nowhere near the difficulties you have faced. My hat's off to you, sir.

Not that im much of a heavy machinery mechanic but 8:35 Is great general advice. Well done. Very well done.

Zeth makes this look so easy!

Excellent video - can't wait for the one on the steering! Seriously. I think you could work on anything you wanted - even airplanes or medical equipment!

mate such a great video very well done keep them up

One podcast I recommend is the Manure Spreader Podcast. It's a farming podcast, but it's a great show to listen to. Like listening to the farmer bs in the coffee lounge at the co-op. Great content you're making here. As a Deere tech out in west Texas, it's interesting to see how the same job is done in other areas of the world.

Surprised the fan was not included as a balanced set. Once said fan was removed I usually place some cardboard against the rad to protect from and ham-fisted-ness accidental dentage of fins I do like the way you work and how you explain the procedures...well done there Lad

شكرا على الفيديو التقني الرائع 👍 عمل جيد و بالتوفيق و النجاح متابع من المغرب from Morocco 🇲🇦

I've not long been following your videos and really enjoy them. If your looking for another service tech/mechanic to watch he is a fellow youtuber like yourself. Only difference being is that he is a sole trader. His channels called Western Truck and Tractor Repair, he works on absolutely every kind of vehicle from pickups to tractors and also heavy plant machinery.

très bonne video bonnes explications!

Great video. Love seeing how these big tractors work. Why would JD have thought balancing wasn't necessary of a heavy cast component in the first place? I come from the automotive world, where even a 5 pound brake drum is balanced.

You are the best

Zeth - Another great video. I'm a mechanical engineer and former mechanic and just can't get enough of your work on these fine JD products. Overall, they are really well designed. Cheers

Great technical stuff here. Useful education to equipment operators and maintainers. There will always be armchair experts or frustrated owners who naturally have a opinion. My personal view is that despite its age, this tractor has low hours for this assembly to require total replacement. It is what it is as they say. Field mechanics on KZfaq sometimes have a low option of shop mechanics. You're doing a great job of countering this view. Like the unused position in the timing cover. Cheers from London

The music is dope 🎶

I never worked on tractors in the workshop , because I am a Millwright in technical trade, always working on Forklifts, reach trucks and mobile harbour cranes and workshop cranes. Really I love your show and wishes to work on tractors like you. You have so much skills and knowledge, although working hard but you had a great heart ❤ to teach others. In this fields of trades mechanical others are selfish to share knowledge. Please keep up your great spirit and wisdom , all the best. We are your fan here in South africa

I like you are the best u are the best because you work for John deere

👍👉 very good jop, thanks for information! lovely greetings from Switzerland from Bern! ✔️🚜👏👍😉👋

Interesting that the bearings on the replacement shaft are closer together! That increases the cantilever load on the bearings and housing by quite a bit and would seem to increase failure chances. Great video as always, Zeth!

Nice job boys, and I don't even own a tractor that big.

The mechanical design people at Deere would derive a huge benefit from communication with the folks that service their products.

I Can still get many parts for my 1984 John Deere 318 garden tractor with an Onan a p218 g motor. So I do respect Deere for that. I've had so many people try to buy that tractor for me and I will never let it go. Also I think I found one of my new favorite channels on KZfaq. It's so hard these days you watch all these other professions and think man why you think I would love to do that but you've already got 20 years invested

So beautiful video very very nice beautiful mkynic

Great Video!! Love watching your videos, so informative. Question? All them parts you replaced where they from Canada and the price was that in US Funds or Canadian?

Man I swear when you started talking about those little white plastic half washer things that it was an absolute prank waiting for a punchline. I cannot believe that was actually a part involved in the process although I guess technically it does make perfect sense. Funny how those things happen

Great vid Zack..... Guess don't need to remind you but tool cart tour coming soon????.......😅😅😅

Great job explaining what you are doing. "I can fix it, or I can upgrade it". Pay me now to upgrade it or pay me now to fix it and later to fix or upgrade it then.

2/17/22; ZK, love yur video, clean & well lighted & clear narration...Great! Then your camera work, also well lighted, close ups great & audio great 👍 👌. Oh yes your tool cart, very nice...but where is the (coffee?) cup holder? (🍺)? Also, where do you place the 'taken-off' parts & matching bolts 🔩, some bolts 🔩 are longer than others! Gotta have some tic-tac-toe # kinda organizational arrangement keeping parts & their bolts kept together/ pigeon-holed, separate from other parts. Hope you can show us armchair YT viewers...calm our anxieties about dirt contamination & bolt mix-ups from self-inflicted problems when reassembling these expensive spline shafts, hubs, sheaves, pullys each with different bolts etc. Also your tools look great, top notch flex-head-box-ratchet wrenches (with padded handle) & that 'glow-in-the-dark' torque wrench with 'Tone (& color lite) Stop' is mighty fine! Yup, ZK, you are the master! Show us more & stay safe!👍👍👍🧑‍🔧🛠😊🚜🍺

are referring to a manual when you are torqueing? crazy question to. do you have to use manuals on these jobs? wow just enjoy watching you videos as i am not a mechanic or a farmer. you do a great job explaining what you do and why. Keep up the great Job !!!!!! my dad was a mechanic all his live. he could listen to a car and tell you what was wrong with it. sorta like what ya have a real skill

I agree, power tools are great, but if you're not careful they do let you break stuff much quicker than you could with standard hand tools.

33:20 Genius :)

At least John Deere has one mechanic that actually double checks his torque. Cheers :)
