- It takes a lot of work on these newer 9L and 13.5L Deere engines just to blow some wind! Vari-Cool fan drive maintenance is super important to keep these high horsepower tractors running nice and cool. In this video we tear into the fan drive of a John Deere 8310R. This iT4 9L engine uses a variable speed fan drive that is hydraulically controlled and if not maintained properly, it can get expensive fast.

Zeth - there's is no chance that I'll ever work on a John Deere tractor however I find myself totally immersed in your videos. You're a true professional and clearly are not only talented but also an asset to Sloan. Your approach and explanations, again while I will unlikely be working on a Deere tractor, are informative and educational. Something that will help me. Thank you, and continued success. Looking forward to future videos.
same here! Greets from Holland
Hello! Thanks for watching!
As a car mechanic who mostly touches european and asian cars I truly enjoy learning about something a bit different from a true expert. Thanks.
Dang, I wish this video was available 2 years ago when I rebuilt the fan drive on our 8345R. Very informative. Thanks for the information
you are the cleanest mechanic I have ever seen
Excellence and pride in his workmanship.!!
This video is absolute easy for normal operator of 8r . Super video feedback 10 !!! Yessssssssssss
squeezing the pulley out to get the belt in before putting the outer shiv on is probably what the master part of MasterTech comes from. Smart and makes perfect sense to see it but I'd probably never think of it if I was fighting that belt!
I am a former A&P mechanic and factory service rep for industrial gas turbines (3,500 to 8,000 shp) before I retired. I applaud your efforts to bring light on a very satisfying and rewarding profession. Good on you!
Thank you!
Another totally absorbing video Zeth - I've become an avid watcher here in the U.K. - you've become my regular evening relaxation! Just think of that next time you wanna curse the position John Deere designers put bolts you can hardly see let alone undo. Interestingly, we are divided by a common language too - oil pans are sumps over here and the two halves of a moving pulley here are sheaves ( sheee-ves, stress on the eee) that system was employed to work a kind of automatic final drive in an European car ( had to Google - it was the Dutch maker DAF and later Volvo) as Variomatic however; I think they managed it purely by centrifugal force rather than hydraulics ( trust J.D. to hook that up to ECU and solenoid actuators!!) Love all of your little "wrinkles" as we would call them here - helpful gems of experience. I have spent many a "happy hour" underneath machines far more ancient than the Green Giants you get to work on - I'm amazed and quite envious of how clean they are - does anyone in the U.S. ever do any work in the rain?
Yes we work in the rain! Try not to though. Thanks for watching!
Hey Zeth. I really like watching your videos. I come from Denmark in Europe, i started my apprenticship i 00 an graduated i 2004 as an agri cultural maschinerymechanic, long word 😜, I have been an ag mechanic for 20 years now and i love my job, new challenges every day.👍 i started at an Massey Ferguson dealer as an apprentics for 4 years. After i got my degree i stayed there for 6 years as an junior tech, and then i got headhunted to my current job at a Claas dealership where i have been for 10 as an Mastertech only servicing Claas tractors, wheelloaders and telehandlers.
I really love watching your channel, you have at lot of skill i what you do with troubleshooting i love watching that part of it.. true detective work😎.
My sister works at the local John deere dealer in the spare parts warehouse.
We have a lot of fights about what is best JD or Claas😜
I would love to hear from you, if you have the time for it.
And if not, just know that you have an deticated fan i Denmark that really loves your work with videos for TH-cam
Thank you very much! You know deep down that John Deere is the best! Lol. Glad you like the channel!
Man your so chill. Move to Oklahoma I need a transmission leak fixed. Kinda scared to fix it. 😬 lol
Just did one today in a s670 combine, job is a lot harder on the combine for sure, great job fellow Deere tech🤙🏻
It sure is!
Viewed 1-20-22 from Illinois Excellent job and appreciate the explaination of why and how you approach the project in ALL your videos !!!!
Love your videos!!!! I’m going to check the fan drives on our 8295R and 8295R in the morning!!!
Cheers mate you're a very good technician greetings from a MAN Mechanic. Greek Aussie!!
Great stuff. I think your videos should be mandatory watching for JD designers. As a retired Mechanical Engineer, I am embarrassed how complex and difficult these machines are to work on. Warren over at Western Truck and Tractor repair is also a great testimony as to the lack of practicality in JD design. A good lesson in the old Detroit 671 series is in order.
That Reeves drive for the fan speed is an elegant, but complex way to control cooling capacity. These machines you work on need lots of effort to keep them moving.
Thanks for showing us your world.
Glad to see someone promote the Ag industry and showcase the complexity of todays equipment.
💪🏼
Working with your hands is also working with your brains!
UR words r so true the amount equipment u have to service those green machines and the sheer work involved in the service is nothin short of engineering bliss thank you for sharing
I don't really know why, but I never miss a new video just love this chanel, it's always fun to watch a professional
Just had my elbow recalibrated this year😂😂😂. Great job on the audio on this video. 👏
Hey ZK, love your vids. I used to be a John Deere salesman for the only remaining Non Ag Pro dealership in Ohio, Polen Implement. I have got some of my former co-workers watching your vids as well. Keep up the great work. Thanks Steve Elson
Hi Zeth, I am an IT professional in the automotive business for 37 years now and living in the Netherlands chances are slim that I will qualify for an apprenticeship with Sloan. Being raised on a dairy farm draws me to everthing concerning AG equipment. I have great admiration for the tranquility, detail and craftsmanship with which you show your work to the world. The footage is also of exceptionally good quality. In two words: fantastic channel!
Thank you!
They certainly have come a long way since the 1960 Olivers I drove and worked on as a teenager on a rice farm. Thanks for the wonderful episodes. After 25 years in my current job retraining for a second career is very interesting to me.
The big difference is the Olivers will still be running long after these over engineered monsters are scrapped
Absolutely crazy how fast your channel is growing Zeth. I’m really happy for you! Love the content and really not surprised people are coming onboard. Congrats!!!
Yeah it's been a wild ride!
Your welcome man from one john deere technician to another
You're certainly a good ambassador for both Sloan and John Deere!
I do snow removal been doing it for the past 12 years last summer I was cutting the side of the highways And I work on 6000 series we also have a 7000 and I love working on the tractors I love your channel and what you do it’s nice to see someone teaching how things get done
I have watched about 12 of your video's. Boy what an eye opener. NEVER had I ever thought that these tractors/farm machinery that you have shown us wer ever that complex. I have often wondered about the engineers that have created, tested, modified, all these machines so that they work well for all the farmers that use these beasts. Thanks for your time. It has been very revealing
Thank you!
I'm from Romania and since i discover your channel i've watched all your videos.Thank you for taking your time to do this for us and personaly i learn new stuff from all your videos. I hope your channel will grow much much bigger because you deserve this.Thank you!
Thank you!
Going to do this job this winter on 8345!!
Your videos on repair and maintenance of all these motors, pullies, shafts and mechanism assemblies are very interesting to watch and learn useful stuff, adding to my basic knowledge of the principles of all them working together. Greetings from Kyiv, Ukraine!
Thanks!
As a master tech myself, in aviation, and three decades, you get to know the feel of the torsion of a bolt, so I understand when you use your well calibrated elbow lol. Great video as usual.
Tractors don’t fall out of the sky when they break down though, calibrated elbow or not.
@@abitoutofsorts aviation has a perfect record, we have never left a plane in the air
KO funny
I am also a mechanic/operator by trade and I enjoy watching your videos. You do a great job explaining things and with editing. I am unfamiliar with John Deere, but many things are similar to other heavy equipment. I was amazed and bemused at the engineering and complexity for a variable-speed fan. Why not just mount the fan blade to a variable-speed hydraulic motor? That whole assembly seems way over-engineered and complicated!
Thanks 👍
I notice today that very few bolts are lubricated when fitted back. I have always lubricated bolts as its easier to remove them next time, (of course some applications require lock tite). I have never had a issue with bolts coming loose in service. This was a very interesting maintenance procedure, I always find it interesting that manufacturers have different spec parts for the same application, for example the bushings. Yes, tight spaces are a challenge for big guys, but then heavy parts are easier for you to lift ! Keep safe and enjoy the green machines
So long as you torque to wet specs. Dry torque is different.
I’m a high school student looking to go in to diesel tech when I graduate next year, right now im in my local Caterpillar dealership intern program on the heavy equipment side to get some experience before I got to trade school, absolutely love the videos, keep up the great work
I’ve never been anywhere near any Big Green Iron, A symbol of Americas greatness, but I do have a New Holland TC 26, for use around my cactus filled two acres in southern Arizona.
Your camera work and expertise and ability to explain what and why you’re doing it is amazing. I love watching.
Thanks! I only use an iPhone for filming and editing.
Awesome video Zeth! 👍 Elbow calibration! 😂😂 Keep up the great work, I look forward to every video you upload!
First, thank you! Second, I’m not an engineer. I don’t design anything. I only fix what’s broken and improve what I can. Everybody always comes up with ideas to change a design that I have no control over. Deere does use hydraulic fans and electric viscous clutches on other tractors.
@@ZKMasterTech And you do a real fine job at fixing things! 👍👍
What a great video was this! Thanks all the way from The Netherlands
Thanks for sharing another part of our industry that's rarely talked about & for inspiring young people into the agriculture repair.
Having commenting on a previous video about my experience years ago at a Case/IH dealership in northern Iowa I want to thank you again for the videos you make. I've move on to being a Fixed Op's Director for a large automotive group back home in Kentucky but you always bring back great memories for me. I still have my completely stocked Snap-on tool box in my garage.
Here's a time stamp point of reference..In 1993 we were the first dealer for Case/IH to install a yield monitoring system on what was then a state of the art 2188 combine. We used a rudimentary pressure plate at the top of the elevator that transferred data to a pcmcia card docked in the cab. Bear in mind..We were strictly with DOS at the time..ahh good times.
Keep doing what you are doing young man. Looking forward to watching this channel grow.
I just love it, when you have the right tools for the job. great job!
I love your humility, skill and unmatched acumen. You are an asset and I am sure John Deere endorses that..God Bless!!
you sir know your stuff it’s good watching you explaining as you go. look forward to seeing you soon
Great repair job Zeth your one great Technician. Keep up the great work. Thanks for sharing.☺️☺️☺️👍👍👍👍
I'm really enjoying your videos, they are very well done. At 75 I'm too old to consider a career change, but these newer tractors require more complex maintenance than my grandfather's Model A and Model G. This would be a great racket to get into.
Zeth , I enjoy watching your video's. They are very informative! Just a little advice from an old John Deere mechanic. When your pressing bearings, always press on the race that is being fitted and not the whole bearing. The chatter of pressing will put dents in the races from the balls. I learned the hard way after having water pump failures shortly after a rebuild, because I was pressing the bearing in by the shaft and not the outer race. Keep up the good work!
I’m always willing to learn and has been learning how to fix this piece of equipment for 12 years now and I’m actually learning a lot from you just by your videos maybe not in full detail but I know enough that I know what needs to be done and while you’re doing it
Thanks for your video’s. I’m not a tech or a farmer but I find these very interesting.
Liked and subscribed. As a technician in material handling I appreciate your content. Keep it up and good luck.
Thank you so much for the video. I’m currently having my 4940 sprayer updated to the dry version and looked high and low for a video explaining the drive. Thanks again.
I am going to school right now for Ag tech! Can't wait to get a job fixing farm equipment! Your videos have gotten me even more excited to learn, and I'm learning new things from your videos! Thank you!
Awesome!!
The first time I worked on a variable speed drive was the transmission drive on a Massey Harris 90 combine back in the early 1960's.
Hi from the Uk
Heavy Goods mechanic by trade until I packed it in back in 99
Don’t know why I’ve started watching your channel because I’ve never had any interest in farming or farm equipment but seem to be hooked and back tracked through your videos
Great content and good explanation to how the equipment works and how you explain stuff
Keep up the good work 👍
Thank you very much!
Easier of a job than I would’ve figured. A good idea but not a good design but sounds like they did a better job with the new design. Had those fan drives replaced on both of our CP690s. Got one on our 8310R that’s gonna need a rebuild or replacement. Always nice to see what it takes to repair what I tear up lol
That is very interested thank you for showing stuff like that I really enjoy your videos
Thanks!
Thanks Zeth ! This is realy a quality video , I work with these tractors and eventhough I am not a mechanic it is always helpful to have a better understanding of the equipment I am working with.
If I were only young again. I really enjoy your videos and the way you explain the process. I think I have to have my grandson look into an apprenticeship.
Awesome!
I am new to the ag industry with very little knowledge I'm, I'm also working for deere, going to be starting my first year of school this year and and you're video are super helpful as far as knowledge and explaining in depth, thanks for the killer content zk
Thank you!
Thanks for another great video. Lots of helpful tips in there. Keep them coming!
Nice video, Passion for iron!
That press is a very old one, we have the same in our shop in Holland.
Please continue with your great video's!
Thanks for the videos. Using this video, I'm just about done going through the fan drive on my 8130. The driver had been updated to the one in the video, but the driven is different. Nevertheless, I've got it about reassembled, thanks again for the videos!
Thank you very much for the demonstration
I just threw a fan belt on our 8245r i hope our setup is the same... wish me luck on the repair
You can do it!
@@ZKMasterTech and I did do it
It wasn't as difficult as I thought it would be
Just did the belt at this stage and will be giving both drives a service next month
Thanks again
I think my decision to go all Milwaukee power tools has been confirmed, even the grease gun is Milwaukee , Thank you DOCTOR ZK, great videos
I bleed Milwaukee lol. Thanks
Great content for those that believe in the Right To Repair. A real service, sir.
its interesting to see this type of CVT drive. i work on golf carts and work on the CVT drives on gas carts a lot. its interesting to the the differences and similarities
They say you should learn something new every day. And I just did that! Thanks Zeth for another excellent video! So glad I found your TH-cam channel! Keep up the great work. I have learned so much from watching your videos. 👍
Just as Frank stated, I will never work on a piece of large equipment John Deere or any other make but I enjoy your video's and you do an excellent job describing what your doing, how to do it and how it works. After watching I'm confidant I could if I had to. Thanks
💪🏼🤘
I have ZEROOOOOOOOOOOOOO interest in working in the AG field but I’ve literally watched every single one of your videos zeth. I’m a 4 year certified Chrysler tech(not fully certified yet) and watching you do all these super big jobs is such an amazement to me. I especially love seeing the electrical repair side of it!!! I highly suggest investing in a pico scope if y’all don’t use one yet for can bus issues. Mopar got a pico 4 channel and I absolutely LOVE using it.
Great video Zeth Love your videos. Keep up the Great work. Hello from Firebaugh California
I enjoy watching. I love to learn and see how stuff works. I doubt I'll ever qork on any of it, but watch all your videos. Great work.
I did almost the exact same repair on my 9460R last fall. Wish I had this video when I did it. I went into it blind but thankfully it was a pretty simple fix. My local deere dealer doesn’t offer this service when tractors come in. They seem to wait and replace the whole drive unit when she goes.
Good luck finding a drive unit now. There are none to be had nation wide.
1st.
Thanks for sharing, I’ve always worked on cars but have an interest in the bigger stuff and you reveal alot about what its like in your day to day working on those amazing machines.

Zeth, you sir are a great teacher and an asset to the trade. If I lived in IL I would look to get back to working on John Deere ag equipment again. I worked for a John Deere dealer here in North Texas about 10 years ago.
Very well done zeth. Sam
Great video, stuffed with useful tips. Thanks Zeth!
Just found this channel and you guys do great work on this channel
We always slip a piece of card board between the fan and the cooler to prevent dinging the cooler.
Hi Zeth
This was another fascinating video. I really enjoy the content and have seen them all. Please keep posting. I own a tractor and all I can do is change the oil, barely!
Thanks!
Zeth, great video. Perhaps you might have a part two to explain why it has to be a somewhat complicated fan drive. Most people will not realise how much horse power is involved in turning that fan and how it can have an effect on fuel consumption. We need the sales dream, we have seen the nightmare ! You make it look easy. Happy New Year.
32:01 who knew John Deere tractors came with chocolate pudding dispensers!
I think it’s awesome your company and Deere allow you to show these repairs! I followed a tech for Kubota and they shut him down….you do great work! Thanks for sharing!
Thank you! Did his dealer shut him down or Kubota corporate?
@@ZKMasterTech the dealer did….
Zeth you're talented in this field. I'm glad you started this channel your skill level blows me away. I enjoy watching and learning how you perform your tech skills and short cuts making the job a lot easier more efficiently. Keep the knowledge coming, definitely look you up at the next one. Stay safe my friend!!
Nice job zeth . You might as well replace all,the seals while you have it apart saves any come backs 👍👍👍👍👍👍👍
ZK, absolutely awesome video, very educational. Not sure I would have removed that pop off and got rid of all that old grease, You sure proved it was a necessary step, man that old grease was nasty looking. Great video, you are exceptional at filming and showing along with explaining how it all works. I really enjoy your videos, I am retired now but have many years under my belt as a tractor trailer mechanic, so this is all relatable. Jay from central Pa.
nice video Zeth!! seems like an awefully complicated and expensive way to have an adjustable fan speed. you would think an electric fan (that could be quickly and easily replaced at interval) or an electric motor driving the fan would be more maintenance friendly than a hydraulic actuated variable speed pulley setup.
great videos /// the price of the work orders to do some of the jobs you work on has to be high -- I know it is a cost of farming these days but if customers follow through the videos they are more likely to say the price is justified and fair // I also think owners should be able to learn how to do some of the checks and repairs themselves which unloads the dealership service shops somewhat // and with the detail you put into the work some customers (like the Welkers) will be able to do the repairs on their own // you provide huge value, hope the channel is being received well
Appreciate you doing these videos and showing more in depth a lot of this tech stuff, both good and bad. Lot of info.
Even though there is a relief valve on them, could it still be due to overgreaseing ruining the seal, and more debris gets in? Seems like bushings in this regard isnt a good thing. Good to hear JD has the improved kit available.
Great Job!
Very nice vid zk
Greatings South africa
Currently a heavy diesel tech, looking to move in to agriculture tech (green ones), gonna use this channel to learn some stuff and get up to speed
Just come on over!
@@ZKMasterTech Just an update to this, interviewed for a job and I start in a few weeks as a combine tech. Gonna keep wathing your videos for sure
Great video Chief! I l learned alot. Thanks
boy technology has come a long way since the early 80's when i farmed.
Great video keep them coming 👍
I feel even at 64 i could still do alot of what you do 😊
Great videos! I like watching your videos, very informative and fun to watch. Keep them going and I'll keep watching them!
Thank you!
You are amazing. It seems this task is needed at almost every oil change, incredible amount of maint for a farm tractor. That dry drive upgrade - seems like the only choice
I've sent a few guys your direction, and a few more to the Sloans intern opportunities.
Thanks!
Your amazing man love your videos thank you
